以编程方式禁用 ScrollView？

发布于 2024-11-02 17:18:36 字数 1230 浏览 8 评论 0原文

我想启用 ScrollView 并通过单击按钮禁用它。
禁用意味着如果 ScrollView 不存在，则启用它会返回 ScrollView。

我想要这样，因为我有一个包含文本图像的画廊，并且单击按钮会更改屏幕方向，因此在横向中文本会变大。我想要 ScrollView 这样图像就不会自行拉伸并且文本变得不可读。

scrollview.Enabled=false / setVisibility(false) 不会做任何事情。

xml：

<ScrollView 
android:id="@+id/QuranGalleryScrollView" 
android:layout_height="fill_parent" 
android:layout_width="fill_parent">
<Gallery android:id="@+id/Gallery" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent"
android:scrollbars="horizontal"></Gallery>
</ScrollView>

我不能使用可见性（消失），因为这也会隐藏图库，我想要的是隐藏 ScrollView 的效果。当有ScrollView时，Gallery中的图像变得可滚动并且不适合屏幕，因此您必须滚动才能看到整个图像。我不想通过单击按钮来禁用/启用它。

我尝试了这个：

((ScrollView)findViewById(R.id.QuranGalleryScrollView)).setOnTouchListener(null);
                        ((ScrollView)findViewById(R.id.QuranGalleryScrollView)).setHorizontalScrollBarEnabled(false);
                        ((ScrollView)findViewById(R.id.QuranGalleryScrollView)).setVerticalScrollBarEnabled(false);
                        ((ScrollView)findViewById(R.id.QuranGalleryScrollView)).setEnabled(false);

但是图库中的图像仍然是可滚动的并且不适合屏幕。解决这个问题的办法是什么？

原文

I would like to enable ScrollView and disable it by a Button Click.
Disable means like if the ScrollView wasn't there, and enable it returns the ScrollView.

I want that because I have a gallery with text images, and on a button click the screen orientation changes, so in Landscape the text becomes bigger. And I want the ScrollView so the image does not stretch itself and the text becomes unreadable.

scrollview.Enabled=false / setVisibility(false) doesn't make anything.

xml:

<ScrollView 
android:id="@+id/QuranGalleryScrollView" 
android:layout_height="fill_parent" 
android:layout_width="fill_parent">
<Gallery android:id="@+id/Gallery" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent"
android:scrollbars="horizontal"></Gallery>
</ScrollView>

I can't use Visibility (gone) since that would also hide the Gallery, what I want is to hide the effect of the ScrollView. When there is ScrollView, the images in Gallery become scrollable and do not fit in the screen so you have to scroll to see the whole image. I don't want to disable/enable that on a button click.

I tried this:

((ScrollView)findViewById(R.id.QuranGalleryScrollView)).setOnTouchListener(null);
                        ((ScrollView)findViewById(R.id.QuranGalleryScrollView)).setHorizontalScrollBarEnabled(false);
                        ((ScrollView)findViewById(R.id.QuranGalleryScrollView)).setVerticalScrollBarEnabled(false);
                        ((ScrollView)findViewById(R.id.QuranGalleryScrollView)).setEnabled(false);

But still the images in the Gallery are scrollable and not fit the screen. What's the solution to this?

首先要注意的几点：

  1. 您无法禁用 ScrollView 的滚动。您需要扩展 ScrollView 并重写 onTouchEvent 方法，以便在匹配某些条件时返回 false。
  2. Gallery 组件水平滚动，无论它是否在 ScrollView 中 - ScrollView 仅提供垂直滚动（您需要一个 Horizo​​ntalScrollView 来进行水平滚动）
  3. 您似乎说图像拉伸本身有问题 - 这与对于 ScrollView，您可以使用 android:scaleType 属性 (XML) 或 setScaleType 方法更改 ImageView 的缩放方式 - 例如ScaleType.CENTER 不会拉伸您的图像，并将其以原始大小居中

您可以按如下方式修改 ScrollView 以禁用滚动，

class LockableScrollView extends ScrollView {

    ...

    // true if we can scroll (not locked)
    // false if we cannot scroll (locked)
    private boolean mScrollable = true;

    public void setScrollingEnabled(boolean enabled) {
        mScrollable = enabled;
    }

    public boolean isScrollable() {
        return mScrollable;
    }

    @Override
    public boolean onTouchEvent(MotionEvent ev) {
        switch (ev.getAction()) {
            case MotionEvent.ACTION_DOWN:
                // if we can scroll pass the event to the superclass
                return mScrollable && super.onTouchEvent(ev);
            default:
                return super.onTouchEvent(ev);
        }
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        // Don't do anything with intercepted touch events if
        // we are not scrollable
        return mScrollable && super.onInterceptTouchEvent(ev);
    }

}

使用

<com.mypackagename.LockableScrollView 
    android:id="@+id/QuranGalleryScrollView" 
    android:layout_height="fill_parent" 
    android:layout_width="fill_parent">

    <Gallery android:id="@+id/Gallery" 
        android:layout_width="fill_parent" 
        android:layout_height="fill_parent"
        android:scrollbars="horizontal">
    </Gallery>

</com.mypackagename.LockableScrollView>

然后您将在 XML 文件中 （刚刚更改） ScrollView 到您的特殊 LockableScrollView）。

然后调用

((LockableScrollView)findViewById(R.id.QuranGalleryScrollView)).setScrollingEnabled(false);

以禁用视图的滚动。

我认为您遇到的不仅仅是禁用滚动的问题，以达到您想要的结果（例如，画廊将使用上面的代码保持可滚动） - 我建议对三个组件中的每一个进行更多研究（画廊， ScrollView、ImageView）来查看每个视图具有哪些属性及其行为方式。

Several points to begin with:

  1. You cannot disable the scrolling of a ScrollView. You would need to extend to ScrollView and override the onTouchEvent method to return false when some condition is matched.
  2. The Gallery component scrolls horizontally regardless of whether it is in a ScrollView or not - a ScrollView provides only vertical scrolling (you need a HorizontalScrollView for horizontal scrolling)
  3. You seem to say you have a problem with the image stretching itself -- this has nothing to do with the ScrollView, you can change how an ImageView scales with the android:scaleType property (XML) or the setScaleType method - for instance ScaleType.CENTER will not stretch your image and will center it at it's original size

You could modify ScrollView as follows to disable scrolling

class LockableScrollView extends ScrollView {

    ...

    // true if we can scroll (not locked)
    // false if we cannot scroll (locked)
    private boolean mScrollable = true;

    public void setScrollingEnabled(boolean enabled) {
        mScrollable = enabled;
    }

    public boolean isScrollable() {
        return mScrollable;
    }

    @Override
    public boolean onTouchEvent(MotionEvent ev) {
        switch (ev.getAction()) {
            case MotionEvent.ACTION_DOWN:
                // if we can scroll pass the event to the superclass
                return mScrollable && super.onTouchEvent(ev);
            default:
                return super.onTouchEvent(ev);
        }
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        // Don't do anything with intercepted touch events if
        // we are not scrollable
        return mScrollable && super.onInterceptTouchEvent(ev);
    }

}

You would then use

<com.mypackagename.LockableScrollView 
    android:id="@+id/QuranGalleryScrollView" 
    android:layout_height="fill_parent" 
    android:layout_width="fill_parent">

    <Gallery android:id="@+id/Gallery" 
        android:layout_width="fill_parent" 
        android:layout_height="fill_parent"
        android:scrollbars="horizontal">
    </Gallery>

</com.mypackagename.LockableScrollView>

in your XML file (just changed the ScrollView to your special LockableScrollView).

Then call

((LockableScrollView)findViewById(R.id.QuranGalleryScrollView)).setScrollingEnabled(false);

to disable scrolling of the view.

I think that you have more than just the issue of disabling scrolling though to achieve your desired result (the gallery will remain scrollable with the above code for instance) - I'd recommend doing some more research on each of the three components (Gallery, ScrollView, ImageView) to see what properties each one has and how it behaves.

我是这样走的：

        scrollView.setOnTouchListener(new View.OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            // TODO Auto-generated method stub
            return isBlockedScrollView;
        }
    });

I had gone this way:

        scrollView.setOnTouchListener(new View.OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            // TODO Auto-generated method stub
            return isBlockedScrollView;
        }
    });

禁用ScrollView

ScrollView sw = (ScrollView) findViewById(R.id.scrollView1);
sw.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        return true;
    }
});

Disablend ScrollView

ScrollView sw = (ScrollView) findViewById(R.id.scrollView1);
sw.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        return true;

我没有足够的观点来评论答案，但我想说 mikec 的答案对我有用，只是我必须将其更改为 return !isScrollable ，如下所示：

mScroller.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
      return !isScrollable;
    }
});

I don't have enough points to comment on an answer, but I wanted to say that mikec's answer worked for me except that I had to change it to return !isScrollable like so:

mScroller.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
      return !isScrollable;
    }
});

首先，我使用了第一个评论中发布的代码，但我将其更改如下：

    public class LockableScrollView extends ScrollView {

    public LockableScrollView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        // TODO Auto-generated constructor stub
    }
    public LockableScrollView(Context context, AttributeSet attrs) 
    {
        super(context, attrs);
    }

    public LockableScrollView(Context context) 
    {
        super(context);
    }

    // true if we can scroll (not locked)
    // false if we cannot scroll (locked)
    private boolean mScrollable = true;

    public void setScrollingEnabled(boolean enabled) {
        mScrollable = enabled;
    }

    public boolean isScrollable() {
        return mScrollable;
    }

    @Override
    public boolean onTouchEvent(MotionEvent ev) {
        switch (ev.getAction()) {
            case MotionEvent.ACTION_DOWN:
                // if we can scroll pass the event to the superclass
                if (mScrollable) return super.onTouchEvent(ev);
                // only continue to handle the touch event if scrolling enabled
                return mScrollable; // mScrollable is always false at this point
            default:
                return super.onTouchEvent(ev);
        }
    }



@Override  
public boolean onInterceptTouchEvent(MotionEvent ev) {
    switch (ev.getAction()) {     
    case MotionEvent.ACTION_DOWN:         
        // if we can scroll pass the event to the superclass      
        if (mScrollable) return super.onInterceptTouchEvent(ev);      
        // only continue to handle the touch event if scrolling enabled    
        return mScrollable; // mScrollable is always false at this point     
        default:          
            return super.onInterceptTouchEvent(ev);      
            }
    }

}

然后我通过这种方式调用它，

((LockableScrollView)findViewById(R.id.scrollV)).setScrollingEnabled(false);

因为我尝试过，

((LockableScrollView)findViewById(R.id.scrollV)).setIsScrollable(false);

但它说 setIsScrollable 未定义，

我希望这会有所帮助你

to start, i used the Code posted posted in the first Comment but i changed it like this:

    public class LockableScrollView extends ScrollView {

    public LockableScrollView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        // TODO Auto-generated constructor stub
    }
    public LockableScrollView(Context context, AttributeSet attrs) 
    {
        super(context, attrs);
    }

    public LockableScrollView(Context context) 
    {
        super(context);
    }

    // true if we can scroll (not locked)
    // false if we cannot scroll (locked)
    private boolean mScrollable = true;

    public void setScrollingEnabled(boolean enabled) {
        mScrollable = enabled;
    }

    public boolean isScrollable() {
        return mScrollable;
    }

    @Override
    public boolean onTouchEvent(MotionEvent ev) {
        switch (ev.getAction()) {
            case MotionEvent.ACTION_DOWN:
                // if we can scroll pass the event to the superclass
                if (mScrollable) return super.onTouchEvent(ev);
                // only continue to handle the touch event if scrolling enabled
                return mScrollable; // mScrollable is always false at this point
            default:
                return super.onTouchEvent(ev);
        }
    }



@Override  
public boolean onInterceptTouchEvent(MotionEvent ev) {
    switch (ev.getAction()) {     
    case MotionEvent.ACTION_DOWN:         
        // if we can scroll pass the event to the superclass      
        if (mScrollable) return super.onInterceptTouchEvent(ev);      
        // only continue to handle the touch event if scrolling enabled    
        return mScrollable; // mScrollable is always false at this point     
        default:          
            return super.onInterceptTouchEvent(ev);      
            }
    }

}

then i called it in by this way

((LockableScrollView)findViewById(R.id.scrollV)).setScrollingEnabled(false);

because i tried

((LockableScrollView)findViewById(R.id.scrollV)).setIsScrollable(false);

but it said that setIsScrollable is undefined

i hope this will help you

这是一个更简单的解决方案。如果您想通过触摸绕过滚动，请覆盖 ScrollView OnTouchListener 的 onTouch() 并返回 false。编程滚动仍然有效，无需扩展 ScrollView 类。

mScroller.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
  return isScrollable;
}
});

Here is a simpler solution. Override the onTouch() for the ScrollView OnTouchListener and return false if you want to bypass the scroll by touch. The programmatic scrolling still works and no need to extend the ScrollView class.

mScroller.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
  return isScrollable;
}
});

我在 NestedScrollView 上有一个布局，消耗触摸事件并禁用滚动：

progressBarLayout.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View view, MotionEvent motionEvent) {
                return true;
            }
        });

并启用：

progressBarLayout.setOnTouchListener(null);

I had a layout over the NestedScrollView consuming the touch event and disable the scroll:

progressBarLayout.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View view, MotionEvent motionEvent) {
                return true;
            }
        });

and to enable:

progressBarLayout.setOnTouchListener(null);

扩展 ScrollView 并重写 onInterceptTouchEvent 以返回 false，在 Kotlin 中：

class SV(context: Context) : HorizontalScrollView(context) {
   var allowUserScroll = false

   override fun onInterceptTouchEvent(ev: MotionEvent?): Boolean {
      return if (allowUserScroll) super.onInterceptTouchEvent(ev) else false
   }
}

这就够了！

（与使用 setOnTouchListener 相比，优点是这样禁用的 ScrollView 不会以任何方式干扰后代的触摸事件处理）

Extend ScrollView and override onInterceptTouchEvent to return false, in Kotlin:

class SV(context: Context) : HorizontalScrollView(context) {
   var allowUserScroll = false

   override fun onInterceptTouchEvent(ev: MotionEvent?): Boolean {
      return if (allowUserScroll) super.onInterceptTouchEvent(ev) else false
   }
}

That's enough!

(The advantage over using setOnTouchListener is that this way the disabled ScrollView does not interfere with touch event handling of descendants in any way)

@JosephEarl +1 他在这里有一个很好的解决方案，对我来说非常适合，只需进行一些小的修改即可以编程方式完成。

以下是我所做的细微更改：

LockableScrollView Class:

public boolean setScrollingEnabled(boolean enabled) {
    mScrollable = enabled;
    return mScrollable;
}

MainActivity:

LockableScrollView sv;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    sv = new LockableScrollView(this);
    sv.setScrollingEnabled(false);
}

@JosephEarl +1 He has a great solution here that worked perfectly for me with some minor modifications for doing it programmatically.

Here are the minor changes I made:

LockableScrollView Class:

public boolean setScrollingEnabled(boolean enabled) {
    mScrollable = enabled;
    return mScrollable;
}

MainActivity:

LockableScrollView sv;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    sv = new LockableScrollView(this);
    sv.setScrollingEnabled(false);

您可以创建一个 CustomScrollView，为此您可以禁用它与其他视图的干扰。尽管这有时会让最终用户感到恼火。请谨慎使用。

这是代码：

import android.content.Context;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.view.ViewParent;

public class CustomScrollView extends android.widget.ScrollView {

    public CustomScrollView(Context context) {
        super(context);
    }

    public CustomScrollView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CustomScrollView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev)
    {
        /* Prevent parent controls from stealing our events once we've gotten a touch down */
        if (ev.getActionMasked() == MotionEvent.ACTION_DOWN)
        {
            ViewParent p = getParent();
            if (p != null)
                p.requestDisallowInterceptTouchEvent(true);
        }

        return false;
    }
}

如何使用CustomScrollView？

您可以将 CustomScrollView 作为父视图添加到要在其中添加另一个 Scrollview 作为子视图的屏幕，并且整个屏幕都是可滚动的。我将其用于相对布局。

<?xml version="1.0" encoding="utf-8"?>
<**package.**CustomScrollView 
xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/some_id"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    xmlns:tools="http://schemas.android.com/tools">
    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
    #**Inside this I had a TableLayout and TableRow. Inside the TableRow,**
    #**I had a TextView which I made scrollable from Java Code.**
    #**textView.setMovementMethod(new ScrollingMovementMethod());**
    </RelativeLayout>
</ankit.inventory.ankitarora.inventorymanagementsimple.CustomScrollView>

它对我的案例有用。

You can make a CustomScrollView, for which you can disable its interference with other views. Though this can be sometimes irritating for the end user. Use it with caution.

This is the code:

import android.content.Context;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.view.ViewParent;

public class CustomScrollView extends android.widget.ScrollView {

    public CustomScrollView(Context context) {
        super(context);
    }

    public CustomScrollView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CustomScrollView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev)
    {
        /* Prevent parent controls from stealing our events once we've gotten a touch down */
        if (ev.getActionMasked() == MotionEvent.ACTION_DOWN)
        {
            ViewParent p = getParent();
            if (p != null)
                p.requestDisallowInterceptTouchEvent(true);
        }

        return false;
    }
}

How to use the CustomScrollView?

You can add CustomScrollView as a parent to the screen in which you want to add another Scrollview as a child view, and the whole screen is scrollable. I used this for a RelativeLayout.

<?xml version="1.0" encoding="utf-8"?>
<**package.**CustomScrollView 
xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/some_id"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    xmlns:tools="http://schemas.android.com/tools">
    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
    #**Inside this I had a TableLayout and TableRow. Inside the TableRow,**
    #**I had a TextView which I made scrollable from Java Code.**
    #**textView.setMovementMethod(new ScrollingMovementMethod());**
    </RelativeLayout>
</ankit.inventory.ankitarora.inventorymanagementsimple.CustomScrollView>

It worked for my case.

科特林：

scrollView.setOnTouchListener { _, _ -> true }

Kotlin:

scrollView.setOnTouchListener { _, _ -> true }

这有帮助吗？

((ScrollView)findViewById(R.id.QuranGalleryScrollView)).setOnTouchListener(null);

Does this help?

((ScrollView)findViewById(R.id.QuranGalleryScrollView)).setOnTouchListener(null);

您可以扩展图库并在需要时使用一些标志来禁用滚动：

public class MyGallery extends Gallery {

public boolean canScroll;

public MyGallery(Context context, AttributeSet attrs) {
    canScroll = true;
    super(context, attrs);
}

public void setCanScroll(boolean flag)
{
    canScroll = flag;
}

@Override
public boolean onScroll(android.view.MotionEvent e1, android.view.MotionEvent e2, float distanceX, float distanceY) {
    if (canScroll)
        return super.onScroll(e1,e2,distancex,distancey);
    else
        return false;
}

@Override
public boolean onSingleTapUp(MotionEvent e)
{
    if (canScroll)
        return super.onSingleTapUp(ey);
    else
        return false;
}

@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY)
{
    if (canScroll)
        return super.onFling(e1,e2,velocityX,velocityY);
    else
        return false;
}
}

You can extend the gallery and use some flag to disable scrolling when you want:

public class MyGallery extends Gallery {

public boolean canScroll;

public MyGallery(Context context, AttributeSet attrs) {
    canScroll = true;
    super(context, attrs);
}

public void setCanScroll(boolean flag)
{
    canScroll = flag;
}

@Override
public boolean onScroll(android.view.MotionEvent e1, android.view.MotionEvent e2, float distanceX, float distanceY) {
    if (canScroll)
        return super.onScroll(e1,e2,distancex,distancey);
    else
        return false;
}

@Override
public boolean onSingleTapUp(MotionEvent e)
{
    if (canScroll)
        return super.onSingleTapUp(ey);
    else
        return false;
}

@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY)
{
    if (canScroll)
        return super.onFling(e1,e2,velocityX,velocityY);
    else
        return false;
}
}

这是 Kotlin 扩展

   @SuppressLint("ClickableViewAccessibility")
fun NestedScrollView.disableScroll() {
    this.setOnTouchListener { _, _ ->
        true
    }
}

@SuppressLint("ClickableViewAccessibility")
fun NestedScrollView.enableScroll() {
    this.setOnTouchListener { _, _ ->
        false
    }
}

@SuppressLint("ClickableViewAccessibility")
fun ScrollView.disableScroll() {
    this.setOnTouchListener { _, _ ->
        true
    }
}

@SuppressLint("ClickableViewAccessibility")
fun ScrollView.enableScroll() {
    this.setOnTouchListener { _, _ ->
        false
    }
}

Here is a Kotlin extension

   @SuppressLint("ClickableViewAccessibility")
fun NestedScrollView.disableScroll() {
    this.setOnTouchListener { _, _ ->
        true
    }
}

@SuppressLint("ClickableViewAccessibility")
fun NestedScrollView.enableScroll() {
    this.setOnTouchListener { _, _ ->
        false
    }
}

@SuppressLint("ClickableViewAccessibility")
fun ScrollView.disableScroll() {
    this.setOnTouchListener { _, _ ->
        true
    }
}

@SuppressLint("ClickableViewAccessibility")
fun ScrollView.enableScroll() {
    this.setOnTouchListener { _, _ ->
        false
    }
}

在按钮单击监听器上只需

ScrollView sView = (ScrollView)findViewById(R.id.ScrollView01);

sView.setVerticalScrollBarEnabled(false);
sView.setHorizontalScrollBarEnabled(false);

这样做，以便在按钮单击时不启用滚动条

on button click listener just do

ScrollView sView = (ScrollView)findViewById(R.id.ScrollView01);

sView.setVerticalScrollBarEnabled(false);
sView.setHorizontalScrollBarEnabled(false);

so that scroll bar is not enabled on button click

正如您在文档中看到的，您无法将可见性设置为 false。在你的情况下，你可能应该使用：

scrollview.setVisibility(Visibility.GONE);

As you can see in the documentation, you cannot set the visibility to false. In your case you should probably use:

scrollview.setVisibility(Visibility.GONE);
