如何使按钮随水平滚动条移动？

我的背景中有一张地图图片，底部有一个按钮，我想用水平滚动条进行滚动。它在开始时与屏幕右侧对齐，我想将其保留在那里。这可能吗？

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" android:id="@+id/mapBackground">
<HorizontalScrollView android:id="@+id/horizontalScrollView1"
    android:layout_height="fill_parent"
    android:scrollbars="none" android:layout_width="fill_parent">
<LinearLayout android:layout_width="fill_parent" android:id="@+id/linearLayout1"
    android:background="@drawable/large_map" android:layout_height="fill_parent"
    android:orientation="vertical"
    android:gravity="bottom">
<LinearLayout android:id="@+id/linearLayout4" android:layout_width="fill_parent"
    android:layout_height="400dp">
</LinearLayout>
<LinearLayout android:layout_height="wrap_content" android:id="@+id/linearLayout5"
   android:layout_width="320dp" android:gravity="right">
<Button android:background="@drawable/bt_play_circle"
    android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/playButton"></Button>
</LinearLayout>
</LinearLayout>
</HorizontalScrollView>
</LinearLayout>

I have a picture of a map in the background with a button on the bottom and I want to make this scroll with the horizontal scroll bar. It is aligned to the right of the screen at the start and I would like to keep it there. Is this possible?

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" android:id="@+id/mapBackground">
<HorizontalScrollView android:id="@+id/horizontalScrollView1"
    android:layout_height="fill_parent"
    android:scrollbars="none" android:layout_width="fill_parent">
<LinearLayout android:layout_width="fill_parent" android:id="@+id/linearLayout1"
    android:background="@drawable/large_map" android:layout_height="fill_parent"
    android:orientation="vertical"
    android:gravity="bottom">
<LinearLayout android:id="@+id/linearLayout4" android:layout_width="fill_parent"
    android:layout_height="400dp">
</LinearLayout>
<LinearLayout android:layout_height="wrap_content" android:id="@+id/linearLayout5"
   android:layout_width="320dp" android:gravity="right">
<Button android:background="@drawable/bt_play_circle"
    android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/playButton"></Button>
</LinearLayout>
</LinearLayout>
</HorizontalScrollView>
</LinearLayout>

您希望在滚动时按钮保留在地图的右侧吗？
将按钮放置在 HorizontalScrollView 之外。
例如，您可以使用RelativeLayout而不是顶部的LinearLayout。

<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
    <HorizontalScrollView>
    ...
    </HorizontalScrollView>
    <Button 
    android:id="@+id/playButton"
    android:background="@drawable/bt_play_circle"
    android:layout_height="wrap_content" 
    android:layout_width="wrap_content"
    android:layout_alignParentRight="true"
    />

</RelativeLayout>

You want the button to stay on the right side over the map while you are scrolling?
Place the button outside the HorizontalScrollView.
You could for example use RelativeLayout instead of the top LinearLayout.

<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
    <HorizontalScrollView>
    ...
    </HorizontalScrollView>
    <Button 
    android:id="@+id/playButton"
    android:background="@drawable/bt_play_circle"
    android:layout_height="wrap_content" 
    android:layout_width="wrap_content"
    android:layout_alignParentRight="true"
    />

</RelativeLayout>
