Answer 1

Try to use DialogFragment :

public class FullScreenDialogFragment extends DialogFragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        return inflater.inflate(R.layout.dialog, container, false);
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        Dialog dialog = super.onCreateDialog(savedInstanceState);
        dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
        return dialog;
    }

    @Override
    public void onStart() {
        super.onStart();
        Dialog dialog = getDialog();
        if (dialog != null) {
            dialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
            dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
        }
    }
}

Answer 2

In your question you have asked how to show full-screen fragment activity?

If you know how to make how to make an activity to full screen. You have to use the same way to make the FragmentActivity full screen. Because FragmentActivity is a subclass of Activity .

   ↳    android.app.Activity
               ↳    android.support.v4.app.FragmentActivity

Also in your question, The class you have included is Fragment , not FragmnetActivity .

If you need to make your fragment full screen you have to make your hosting activity fullscreen.

use getActivity() method to get hosting activity from the fragment. Then you can make the fragment fullscreen.

The answer by @shmakova worked for me, but then my colleague pointed out a simpler solution. It is enough to have the dialog's style inherit from a style, whose name ends with NoTitleBar.Fullscreen and add a windowNoTitle element. For example: In my Dialog:

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    return new AppCompatDialog(getActivity(), R.style.MyDialogStyle);
}

in src/main/res/values/styles.xml :

<style name="MyDialogStyle" parent="@android:style/Theme.Light.NoTitleBar.Fullscreen">
    <item name="windowNoTitle">true</item>
</style>

There are several advantages of such an approach: you don't have to override onCreateDialog and can have multiple styles.xml instances depending on device features. For example, you can have your dialog extend to full screen only on the smaller screens.

try this solution

public class setWallpaperFragment extends DialogFragment {

    public setWallpaperFragment() {
        // Required empty public constructor
    }

    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        int theme = android.R.style.Theme_Black_NoTitleBar_Fullscreen;
        setStyle(DialogFragment.STYLE_NO_TITLE,theme);
    }
