How to set color for drawable background in android

Question

I want to create a view like this in android studio https://i.sstatic.net/BTm5P.png

As you can see, three views are using the same background but with different colors. I wonder how to create a view like this with only one drawable background file. Three views are using the same drawable background file, and I can set a different color for each view.

Answer 1

You can use android:backgroundTint for this purpose.

For example:

1. Define rounded drawable (ex: rounded.xml)

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
   android:shape="rectangle">
    <corners android:radius="10dp" />
</shape>

2. Set your color with backgroundTint

<RelativeLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:backgroundTint="@color/black"
    android:background="@drawable/rounded"/>
