xml - Android: Can I re-use a layer-list? -

-

when implementing selectors buttons , listview items, keep finding want reuse same item/background state_pressed , state_focused.

instead of duplicating xml 'code', possible re-use ?

e.g. here state_pressed 'code' - how can state_focused use same lump of 'code' without duplicating all?

<?xml version="1.0" encoding="utf-8"?> <selector     xmlns:android="http://schemas.android.com/apk/res/android">    <item android:state_pressed="true">     <layer-list xmlns:android="http://schemas.android.com/apk/res/android">      <!--  pds: side lowlight lines inset hidden underneath solid colour -->     <item android:bottom="0dp" android:right="0dp" android:top="0dp" android:left="0dp">       <shape>           <solid  android:color="#00000000" />           <stroke android:color="@color/butgreyselectframe" android:width="4dp"/>           <corners android:radius="4dp" />                     </shape>          </item>       <!-- pds: solid colour -->      <item android:left="4dp" android:right="4dp" android:top="4dp" android:bottom="4dp">                     <shape>         <solid android:color="@color/butgreyselectback" />         <padding             android:left="10dp"             android:top="10dp"             android:right="10dp"             android:bottom="10dp" />       </shape>       </item>      </layer-list> </item>

yes, drawable can reused in selector.

just create separate file layer-list, reference with

<item android:state_xxx android:drawable="@drawable/the_resource" />
