selector代码：

// 整个条目北京selector
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@color/white" android:state_window_focused="false" />
    <item android:drawable="@color/lightgray" android:state_focused="true" android:state_pressed="true" />
    <item android:drawable="@color/lightgray" android:state_focused="false" android:state_pressed="true" />
    <item android:drawable="@color/lightgray" android:state_selected="true" />
    <item android:drawable="@color/lightgray" android:state_focused="true" />
</selector>

// 对号的selector
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
