[android] Android LinearLayout Gradient Background

It is also possible to have the third color (center). And different kinds of shapes.

For example in drawable/gradient.xml:

<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <gradient
        android:startColor="#000000"
        android:centerColor="#5b5b5b"
        android:endColor="#000000"
        android:angle="0" />
</shape>

This gives you black - gray - black (left to right) which is my favorite dark background atm.

Remember to add gradient.xml as background in your layout xml:

android:background="@drawable/gradient"

It is also possible to rotate, with:

angle="0"

gives you a vertical line

and with

angle="90"

gives you a horizontal line

Possible angles are:

0, 90, 180, 270.

Also there are few different kind of shapes:

android:shape="rectangle"

Rounded shape:

android:shape="oval"

and problably a few more.

Hope it helps, cheers!
