Gradient color drawable not working properly on Android 10 (rotated 90 degrees)

Question

I applied a gradient drawable resource as a background for a view.

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <corners android:radius="10dp" />
    <gradient
        android:startColor="#cf2aff"
        android:endColor="#5409ff"
        android:type="linear" />
</shape>

In devices with Android version < 10 it is shown as expected:

But in devices with Android 10 it is rotated 90 degrees:

Did anyone have the same problem and know how to fix it?

Answer 1

Add android:angle="0"

I got a fix for this. You need to set android:angle attribute even if it is 0 to make it work on Android 10.

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <corners android:radius="10dp" />
    <gradient
        android:angle="0"
        android:startColor="#cf2aff"
        android:endColor="#5409ff"
        android:type="linear" />
</shape>

I suppose for Android 10, angle is set to 90 degrees by default.
