Change the color of the navigation bar, Android

Question

How to change the color / transparency of the navigation bar from black to the general color in devices before Lollipop (for example, the color of the status bar or action bar)?

Can I do this using AppCompat or is this only possible for SDK 21?

Answer 1

You can set the navigationBarColor attribute in the AppCompat theme or android:navigationBarColor in the native v21 theme.

 <style name="AppTheme" parent="@style/Theme.AppCompat.Light"> ... <item name="navigationBarColor">#123456</item> </style>

Please note that this does not work on Pre-Lollipop devices, since this function must be supported by the system, which is not available in Android 4.4 or later.

Answer 2

Another software way:

 window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS); window.setStatusBarColor(getResources().getColor(R.color.DarkOrange)); window.setNavigationBarColor(getResources().getColor(R.color.red)); 

Next, to change the color of the status bar, add the following line:

 window.setStatusBarColor(getResources().getColor(R.color.green));
