Resize bitmap inside a drawable layer-list

Question

Currently I\'m developing a Android application. I want to make a text (a header) with a background that looks like this:

 _______
/______/

Answer 1

I solved it using two (half-transparant) images which represent the corners.

The XML looks like this:

<?xml version="1.0" encoding="UTF-8"?> 
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
        <item>
                <shape>    
                    <gradient
                      android:startColor="@color/jaarkleur"
                      android:centerColor="@color/jaarkleur"
                      android:endColor="#E66C2C00"
                      android:angle="0" />
                    <stroke android:width="1dp"
            android:color="#ff000000"
            />       
                </shape>
        </item>
        <item>
            <bitmap android:src="@drawable/overlay_left" android:gravity="left|top"  />
        </item>
        <item>
            <bitmap android:src="@drawable/overlay_right" android:gravity="right|bottom" />
        </item>        
</layer-list>

Answer 2

Instead of using a layer-list with gradient / border stroke and a custom image, consider using a NinePatchDrawable.

There is also a handy 9-patch creater that comes with the android SDK.
