如何从选择器更改textView颜色

发布于 2024-12-23 21:40:07 字数 282 浏览 1 评论 0原文

我有带有 textView 的 LinearLayout 。

我已经从选择器中设置了 LinearLayout 背景

android:background="@drawable/tab_bg_selector"

，所以当按下布局时它会更改背景颜色

我的问题是如何在按下布局时更改文本颜色

我需要类似 onStateChangeListner 的东西，所以当用户按下布局时它也会更改文本颜色

谢谢，

托默

重复如何在以下情况下使形状的子 TextView 变为白色state_pressed="true" 这几乎是正确的答案。 licateParentState="true" 将父级 ListView 选择状态传输到子级 TextView。以下对我有用：

<TextView
    android:duplicateParentState="true"
    android:textColor="@drawable/text_selector"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" />

和 text_selector：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true"
        android:color="@color/text_on" /> <!-- pressed -->
    <item android:state_focused="true"
        android:color="@color/text_on" /> <!-- focused -->
    <item android:color="@color/text_off" /> <!-- default -->
</selector>

Duplicate of How to make shape's child TextView white when state_pressed="true" which is pretty much the correct answer. duplicateParentState="true" transfers the parent ListView selection state to the TextView child. The following worked for me:

<TextView
    android:duplicateParentState="true"
    android:textColor="@drawable/text_selector"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" />

and the text_selector:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true"
        android:color="@color/text_on" /> <!-- pressed -->
    <item android:state_focused="true"
        android:color="@color/text_on" /> <!-- focused -->
    <item android:color="@color/text_off" /> <!-- default -->
</selector>

只需尝试使用此代码 -

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
}
public void clickme(View view)
{
    TextView tv = (TextView)findViewById(R.id.textView1);
    tv.setTextColor(Color.RED);             
}

Main.xml

<?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:onClick="clickme"
android:orientation="vertical" >


<TextView
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal"
    android:text="Large Text"
    android:textAppearance="?android:attr/textAppearanceLarge" />
</LinearLayout>

使用您的选择器尝试此操作。

Just try with this code -

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
}
public void clickme(View view)
{
    TextView tv = (TextView)findViewById(R.id.textView1);
    tv.setTextColor(Color.RED);             
}

Main.xml

<?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:onClick="clickme"
android:orientation="vertical" >


<TextView
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal"
    android:text="Large Text"
    android:textAppearance="?android:attr/textAppearanceLarge" />
</LinearLayout>

Try this with your Selector.
