LinearLayout按下(pressed)或获取焦点（focused)时背景设置不同颜色或图片

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/myview"
    android:orientation="horizontal"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:gravity="top"
    android:background="@drawable/myDrawable"
    android:clickable="true"



>
</LinearLayout>

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

 千万注意上面红色标注的地方，一定要加这个属性，不然不起作用,另外在color.xml中可以定义drawable和color等多种属性，害我老是报找不到@color匹配的项，原来一直都在写drawable，尼玛！！！！！
