How can I position a radial gradient shape as background in a LinearLayout ? Here is what I presently have :
The shape :
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<gradient
android:endColor="#e6e6e6"
android:gradientRadius="800"
android:startColor="#fafaf9"
android:type="radial"/>
</shape>
The LinearLayout :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/accueil_bg_gradient">
</LinearLayout>
I just want to have my gradient starting from the left upper corner of the screen, and ending at the right lower corner.
Thanks a lot !

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>

<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" />
