Android - Making activity full screen with status bar on top of it

Question

I have used this code in manifest inside activity

Answer 1

Put this code in your Activity onCreate this will hide the status bar

View decorView = getWindow().getDecorView();
// Hide the status bar.
int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
// Remember that you should never show the action bar if the
// status bar is hidden, so hide that too if necessary.
ActionBar actionBar = getActionBar();
actionBar.hide();
