    In the manifest:

    <activity android:name=".ActivityName" android:label="@string/app_name" android:theme="@android:style/Theme.NoTitleBar.Fullscreen"/>

    Or programmatically:

     public class ActivityName extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // remove title requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); setContentView(R.layout.main); } }

      Yes you can. It is necessary to set:

       actionBar.setStackedBackgroundDrawable(new ColorDrawable(Color.parseColor("#33aaccbb")));

      Where color is set in ARGB format ( #33aaccbb ) - the first byte shows transparency, the rest in RGB colors.

      PS In the first version, the question was about the transparency of the action bar :)

      • Well, if actionBar==null then I’m not guilty - learn how to extract it correctly! - Barmaley
      • I'll try to figure it out. I guess I was wrong somewhere. - Jason Statham
      • wrote so, but the transparency of the ActionBar does not change actionBar = getSupportActionBar (); actionBar.setStackedBackgroundDrawable (new ColorDrawable (Color.parseColor ("# 33aaccbb"))); - Jason Statham
