<item>
    <bitmap android:src="@drawable/bg"/>
    <shape>
        <gradient
            android:startColor="#631f68"

Solution:

In your main_activity.xml,

set the background image for your topmost layout: (Relative or Constraint whatever you are using)

Then take another layout and give height and width to match_parent and apply the below Gradient to the background of it.

Gradient file:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <gradient
        android:angle="135"
        android:centerColor="@color/colorAccentSecondary"
        android:endColor="@color/colorPrimary"
        android:startColor="@color/colorAccent"
        android:type="linear" />

    <corners android:radius="0dp" />
</shape>

Hope it helps.
