刚开始在item中使用findViewById找到其中的控件改变控件的显示状态，结果发现改变了多个item，纠结了半天，原来要使用position可以解决，多谢多谢！

Answer 4

<?xml version="1.0" encoding="utf-8"?>
<selector
  xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" android:drawable="@color/123456"></item>
    <item android:state_selected="true" android:drawable="@color/234567"></item>
    <item android:drawable="@android:color/345678"></item>
</selector>
把颜色改成你想要的就行了吧
