Nested shapes in Android

Question

I am trying to draw a shape that has three rectangular shapes:
1. solid color 2. gradient 3. white line
How do I do that? When I try this, it does not work. The layout has the parent color.

<shape 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle"
    android:height="60px"
    >
    <shape 
        android:shape="rectangle" 
        android:height="30px"
        >
        <solid 
            android:color="#ff297baf" 
            />
    </shape>
    <shape 
        android:shape="rectangle"
        android:height="30px"
        >
         <gradient
  android:type="linear"
  android:startColor="#ff297baf"
  android:endColor="#ff16c0e3"
  android:angle="270"/> 
    </shape>
    <shape
        android:shape="rectangle"
        android:height="3px"
        >
        <solid 
            android:color="#FFFFFFFF"
            />
    </shape>
</shape>

I am trying to make a gradient in 3 colors. Start with a solid color #ff297baf, at 60% start a gradient from #ff297baf to #ff16c0e3 and add a while line at the end.

If you're going to look into using multiple shapes, you should try a LayerListDrawable. Something like this works for me, but only for your example height of 60px. You may have to modify it to suit your needs exactly, but this should get you a good start:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
    <shape android:shape="rectangle">
        <gradient
            android:angle="270"
            android:endColor="#ff16c0e3"
            android:startColor="#ff297baf"
            android:type="linear" />
    </shape>
</item>
<item android:top="57px">
    <shape android:shape="rectangle">
        <solid android:color="#FFFFFFFF" />
        <size android:height="3px" />
    </shape>
</item>
