Is it possible to use several 9 patch images inside LayerDrawable?

I want to use two nine patches inside LayerDrawable

   <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
       <item android:id="@+id/solid">
           <nine-patch android:src="@drawable/button_header_solid" android:dither="true" />
       </item>
       <item android:id="@+id/transparent">
           <nine-patch android:src="@draw开发者_如何学JAVAable/button_header_transparent" android:dither="true" />
       </item>
   </layer-list>

And it seems that only first layer is stretched while second one stays as is.

Both images are of the same size as .png, and have equal stretchable and padding areas.

The question is: Do we allowed to use several 9-patches (in one layer-list) or only one is allowed?

Thanks.

Just now faced with the same problem. Try this:

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
       <item android:id="@+id/solid">
           <nine-patch android:src="@drawable/button_header_solid" android:dither="true" />
       </item>
       <item android:id="@+id/transparent">
           <clip>
              <nine-patch android:src="@drawable/button_header_transparent" android:dither="true" />
           </clip>
       </item>
   </layer-list>

The following makes both 9-patches behave as you would expect (tested on Android 2.2). Both 9-patches are expanded to fill the whole drawable area.

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/solid" 
        android:drawable="@drawable/button_header_solid"/>
    <item android:id="@+id/transparent" 
        android:drawable="@drawable/button_header_transparent"/>
</layer-list>
