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！！！！！
