如何向工具栏添加颜色渐变（Android）

Question

I want to add a color gradient to my toolbar (app bar/title bar).

I've created an xml gradient file to the drawable folder called "side_nav_bar.xml".

side_nav_bar.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
    android:angle="135"
    android:endColor="#7524f6"
    android:startColor="#2691f6"
    android:type="linear" />

I found some suggestions on the internet to create a new custom toolbar then set this as the background image etc. But I don't have enough info about this.

Any help will be highly appreciated. Thanks.

Try this

ActionBar actionbar = getSupportActionBar();
actionbar.setBackgroundDrawable(getResources().getDrawable(R.drawable.side_bar_nav));
