Question

我正在使用此代码表在不同的事件中定义textView的颜色。 textView位于listView（10个以上项目）中，效果（颜色）适用于每个listItem中的每个textView。如何才能更改仅按下的textView的颜色？

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item
    android:state_focused="true"
    android:state_pressed="true"
    android:color="@color/text_white" />
  <item
    android:state_focused="false"
    android:state_pressed="true"
    android:color="@color/text_white" />
  <item
    android:state_focused="true"
    android:color="@color/text_white" />
  <item
    android:state_selected="true"
    android:color="@color/text_white" />
  <item
    android:state_checked="true"
    android:color="@color/text_white" />
  <item
    android:state_selected="false"
    android:state_checked="false"
    android:state_focused="false"
    android:state_pressed="false"
    android:color="@color/text_blue" />
</selector>

    <selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_focused="true" //<<<<<Here focus us true then txt_pressed
          android:state_pressed="false" 
          android:drawable="@drawable/txt_pressed" />
    <item android:state_focused="true" 
          android:state_pressed="true"
          android:drawable="@drawable/txt_pressed" />
    <item android:state_focused="false" 
          android:state_pressed="true"
      android:drawable="@drawable/txt_pressed" />
    <item android:drawable="@drawable/txt_default" />
</selector>

在xml文件中，要想要更改颜色的textview，请添加

 android:background="@drawable/filename"

如何仅更改按下的textView的颜色？
