How to Make Gradient Background in Android

How to make gradient background in android

You can create this 'half-gradient' look by using an xml Layer-List to combine the top and bottom 'bands' into one file. Each band is an xml shape.

See this previous answer on SO for a detailed tutorial: Multi-gradient shapes.

Android LinearLayout Gradient Background

Ok I have managed to solve this using a selector. See code below:

main_header.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="50dip"
    android:orientation="horizontal"
    android:background="@drawable/main_header_selector">
</LinearLayout>

main_header_selector.xml:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
    <shape>
        <gradient
            android:angle="90"
            android:startColor="#FFFF0000"
            android:endColor="#FF00FF00"
            android:type="linear" />
    </shape>
</item>
</selector>

Hopefully this helps someone who has the same problem.

Set the background colour of a Layout view to a gradient in Android?

create gradient.xml in /res/drawable:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <gradient
        android:startColor="#FFFFFF"
        android:endColor="#00000000"
        android:angle="45"/>    
</shape>

and in your main.xml layout file in /res/layout:

<?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/gradient"
    >   
</LinearLayout>

you can specify the angle by replacing the android:angle value and start/end colour by replacing android:startColor and android:endColor

How to set a gradient background to a Material Button?

To use a custom drawable background with the MaterialButton you can use the android:background attribute:

<MaterialButton
    app:backgroundTint="@null"
    android:background="@drawable/bkg_button_gradient"
    ... />

NOTE: It requires at least the version 1.2.0-alpha06

Currently it is very important to add app:backgroundTint="@null" to avoid that the custom background doesn't get tinted by default with the backgroundTint color.

With lower versions of the Material Components Library you have to use an AppCompatButton.

How to set a gradient background in a Material Button from Material Components?

From the documentation for MaterialButton:

Do not use the android:background attribute. MaterialButton manages its own background drawable, and setting a new background means MaterialButton can no longer guarantee that the new attributes it introduces will function properly. If the default background is changed, MaterialButton cannot guarantee well-defined behavior.

The only supported way to modify the background of the button is to set a color value to the app:backgroundTint attribute. Unfortunately, gradients are not supported here either; you can only use a simple color value or a ColorStateList.

So, there is no supported way to use a gradient background with MaterialButton.

    android:angle="-90"/>

I got the solution. By adding this code in the button xml file, it worked just fine.
