Answer 1

If your activity needs to extends from AppCompatActivity, you can create a custom style for your activity

And then change the default style of your activity in the Manifest

Otherwise, if you do not need your activity to extend from AppCompatActivity, just change the theme of your activity in the manifest in this way.
