レイアウトである：blue_gradient.xml /描画可能 RES /ここ

<?xml version="1.0" encoding="utf-8"?> 
<shape xmlns:android="http://schemas.android.com/apk/res/android" 
    android:shape="rectangle" > 
    <gradient 
     android:startColor="#003399" 
     android:endColor="#002288" 
     android:angle="270" 
    /> 
</shape>
