How to position radial gradient background

You can move the middle of the radial gradient at a different position of the drawable using "centerX" and "centerY" attributes of the gradient. They are a floating point values ranging from 0 to 1.0 where (values of centerX,centerY accordingly) 0,0 is upper left and 1,1 is bottom right corner.

Default is 0.5,0.5 which is the middle of the drawable / assigned space.Example for a 100px long (radius), black-white gradient whose middle starts at upper left corner would be:

    <shape android:shape="rectangle">        <gradient            android:type="radial"            android:startColor="#ffffff"            android:endColor="#000000"            android:gradientRadius="100"            android:angle="270"            android:centerX="0"            android:centerY="0"/>    </shape>

set this as background mybackground.xml:

<?xml version="1.0" encoding="utf-8"?><layer-list xmlns:android="http://schemas.android.com/apk/res/android">    <item>        <shape android:shape="rectangle" android:layout_width="wrap_content">            <stroke android:width="10dp" android:color="@color/darkBlue" />            <solid android:color="#00000000" />            <padding android:left="1dp" android:top="1dp" android:right="1dp"                android:bottom="1dp" />        </shape>    </item>    <item>        <shape android:shape="rectangle">            <gradient android:startColor="@color/grayBlue"                android:endColor="@color/lightBlue" android:angle="270"                android:centerColor="@color/lightBlue" />            <!-- border width and color -->            <stroke android:width="1dp" android:color="#FFDDDDDD" />            <padding android:left="10dp" android:top="8dp" android:right="10dp"                android:bottom="8dp" />        </shape>    </item></layer-list>
