How to set dialog to show in full screen?

Question

I have a GridView and i want to make an implémentation of a dialog, on which the picture that i have selected should display in full screen.

so how can i make the dialog shows in a full screen mode ? thanks!

If you want to use a FULL SCREEN `Dialog`, why not just use the default `ACTION_VIEW` `Intent` for image files? — Will Tate, Jun 13 '11 at 10:45
In conjunction with answer to willytate if you have to dialog then use android.R.style.Theme_Translucent_NoTitleBar_Fullscreen in theme — ingsaurabh, Jun 13 '11 at 10:50
I do NOT understand why this question get closed. Annoying. Have a suggestion, but can't post. Kudos to @Andrew Barber!!! -.- — Martin Pfeffer, Apr 18 '17 at 11:58
@MartinPfeffer i also have a suggestion for future user but question closed Andrew Barber is not from android community. this is really a simple question new android developers always curious about this. this question should be open again for better answers and future users — Abhishek Singh, Mar 23 '18 at 07:42

For this to work for me I had to use android.R.style.Theme_Black_NoTitleBar_Fullscreen – Ben Clayton Nov 23 '11 at 17:43

What about fullscreen _with_ a titlebar? – Heath Borders Nov 25 '13 at 21:27

When I do this (using `DialogFragment`) I see the status bar color is killed by the dialog, the whole screen is the dialog's background color. Does anyone know of a workaround? I tried setting the statusBarColor of the dialog's window, to no effect. P.S.: navigation bar color gets killed too. – androidguy Dec 22 '16 at 08:39
But it gets black color as background how to change it? – VVB Sep 19 '17 at 08:10
still shows a gap where the statusbar should be... – desgraci Oct 30 '17 at 22:09
you could use any theme with Fullscreen at the end of it, for me android.R.style.Theme_Holo_NoActionBar_Fullscreen worked the best, Theme_Black adds backgrounds to my EditTexts. – Meisam Nov 08 '17 at 06:09

In kotlin it is: `dialog = Dialog(context!!, android.R.style.Theme_Black_NoTitleBar_Fullscreen)` – Shailendra Madda Dec 21 '19 at 14:27

For fullscreen Dialog with titlebar you can use android.R.style.Theme_Black_NoTitleBar – Ban Markovic Sep 16 '20 at 14:18

based on this link , the correct answer (which i've tested myself) is:

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

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

in addition , set the style of the dialog to :

<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 could be achieved via the 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 to android.R.style.ThemeOverlay and that's it.

EDIT2: To support material library, add Gradle dependency to app(module) build.gradle file

implementation "com.google.android.material:material:$material_version"

Then set dialog's theme to R.style.ThemeOverlay_MaterialComponents

With my try, this one is the only work one. `android.R.style.ThemeOverlay` is the key. – Yeung Jun 11 '21 at 11:31
@Yeung I wonder if `ThemeOverlay.MaterialComponents` is also suitable. Can you please check? – android developer Jun 12 '21 at 00:31

Tried. It works, but don't know it is useful or not as I am developing with an old Android 5 device. – Yeung Jun 15 '21 at 08:13
@Yeung I think it's better than what I wrote, then. Supports new material library. Can you please write me what exactly you did, so that I could update my answer ? Or maybe you could edit mine? – android developer Jun 15 '21 at 10:41
When deal with old issue, just found this also has reference value `getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(any bg color));` will "expand" the dialog's width to fullscreen which no need to set theme `android.R.style.ThemeOverlay` . Notice that for "width" only. – Yeung Jun 22 '21 at 06:31
For me `ThemeOverlay.MaterialComponents` was enough. Thanks. – Ahmad Reza Enshaee Oct 13 '22 at 14:28

The easiest way I found

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

EDIT Until such time as StackOverflow allows us to version our answers, this is an answer that works for Android 3 and below. Please don't downvote it because it's not working for you now, because it definitely works with older Android versions.

You should 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;
}

Why I can't use FLAG_FULLSCREEN – user790156 Jun 13 '11 at 10:52

Well, that's hard to say - Did you import LayoutParams? Is your layout xml set to either fill_parent or match_parent? – Caspar Harmer Jun 13 '11 at 19:03

use android.view.WindowManager.LayoutParams.FLAG_FULLSCREEN – Derzu Jun 14 '12 at 20:49

It's possible that this answer is getting out of date - it might not work for android 4.0 and up. – Caspar Harmer Jun 16 '13 at 22:50
@CaspNZ In android 4.0+, you should override the `DialogFragment`s `onCreateDialog` method. This way, everything is cool. ;-) – Lovis Oct 14 '13 at 11:34
This was driving me nuts, whenever I created the Dialog the top region was clipped although it seems the window was actually fully sized (e.g. the window background was also clipped). I set LayoutParams.FLAG_FULLSCREEN after requestWindowFeature(Window.FEATURE_NO_TITLE) but before setContentView() – mwk Feb 19 '14 at 23:28
you need to import like: import android.view.WindowManager; – Jan Ziesse Dec 03 '14 at 10:12
this not worked for me .... in api 18 ... android studio emulator – iman kazemayni Mar 07 '17 at 06:54
This is a very old answer. It's possible that it no longer works in newer versions of the API – Caspar Harmer Mar 07 '17 at 08:38

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 this.
