Answer 1

to try

Dialog dialog=new Dialog(this,android.R.style.Theme_Black_NoTitleBar_Fullscreen) 

Answer 2

based on this link , the correct answer (which I tested myself):

put this code in the constructor or in the onCreate() method of the dialog box:

 getWindow().setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT); 

add a dialogue style:

 <style name="full_screen_dialog"> <item name="android:windowFrame">@null</item> <item name="android:windowIsFloating">true</item> <item name="android:windowContentOverlay">@null</item> <item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item> <item name="android:windowSoftInputMode">stateUnspecified|adjustPan</item> </style> 

this can be achieved using a constructor, for example:

 public FullScreenDialog(Context context) { super(context, R.style.full_screen_dialog); ...

EDIT: An alternative to all of the above would be to set the style for android.R.style.Theme and what it is.

Answer 3

EDIT Until StackOverflow allows us to update our answers, this is an answer that works for Android 3 and below. Please do not reduce it, because it does not work for you now, because it definitely works with older versions of Android.

You only need to add one line to your onCreateDialog() method:

 @Override protected Dialog onCreateDialog(int id) { //all other dialog stuff (which dialog to display) //this line is what you need: dialog.getWindow().setFlags(LayoutParams.FLAG_FULLSCREEN, LayoutParams.FLAG_FULLSCREEN); return dialog; } 

Answer 4

The easiest way to find

 Dialog dialog=new Dialog(this,android.R.style.Theme_Black_NoTitleBar_Fullscreen); dialog.setContentView(R.layout.frame_help); dialog.show(); 

Answer 5

 dialog = new Dialog(getActivity(),android.R.style.Theme_Translucent_NoTitleBar); dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); dialog.setContentView(R.layout.loading_screen); Window window = dialog.getWindow(); WindowManager.LayoutParams wlp = window.getAttributes(); wlp.gravity = Gravity.CENTER; wlp.flags &= ~WindowManager.LayoutParams.FLAG_BLUR_BEHIND; window.setAttributes(wlp); dialog.getWindow().setLayout(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT); dialog.show(); 

try it.
