How do you animate the change of background color of a view on Android ?

The idea is to use this code snippet. ColorDrawable[] colorDrawables = { new ColorDrawable(Color.RED), new ColorDrawable(Color.BLUE), new ColorDrawable(Color.GREEN) }; TransitionDrawable transitionDrawable = new TransitionDrawable(colorDrawables); textView.setBackground(transitionDrawable); transitionDrawable.startTransition(2000); In this code snippet, we created a list of colorDrawables, then feed them to the TransitionDrawable. And now we have an animating color change, so we pass it to the setBackground to get the animating colors in the background. Got the idea ? let’s create a complete code example. use this xml code in res/layout/activity_main.xml. <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:id="@+id/relativeLayout" android:padding="8dp" tools:context=".MainActivity"> <Button android:id="@+id/button" android:text="Animate background color" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_above="@id/textView" android:layout_centerInParent="true" android:layout_marginBottom="15dp"/> <TextView android:id="@+id/textView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textSize="36sp" android:textStyle="bold" android:text="Changing Background color of this view.
