Android Selector和Shape的组合

1.自定义控件背景是需要selector，需要使用自定义颜色(图片不方便)，所以需要两者组合

<selectorxmlns:android="http://schemas.android.com/apk/res/android">

    <item android:state_pressed="false">        <shape android:shape="rectangle">            <solid android:color="@color/btn_blue_common"></solid>        </shape>    </item>    <item android:state_pressed="true">        <shape android:shape="rectangle">            <solid android:color="@color/btn_blue_press"></solid>        </shape>    </item></selector>
