How to change background color in android app

Question

I want to be able to change the background color to white in my android app in the simplest way possible.

Answer 1

You need to use the android:background property , eg

android:background="@color/white"

Also you need to you need to add a value for white in the strings.xml

<color name="white">#FFFFFF</color>

Answer 2

You can also use

android:background="#ffffff"

in your xml layout, or you can change the theme in your AndroidManifest.xml by adding

android:theme="@android:style/Theme.Light"

to your activity tag.

If you want to change the background dynamically, use

YourView.setBackgroundColor(Color.argb(255, 255, 255, 255));
