Full Screen DialogFragment in Android

To get DialogFragment on full screen

Override onStart of your DialogFragment like this:

@Overridepublic void onStart(){    super.onStart();    Dialog dialog = getDialog();    if (dialog != null)    {        int width = ViewGroup.LayoutParams.MATCH_PARENT;        int height = ViewGroup.LayoutParams.MATCH_PARENT;        dialog.getWindow().setLayout(width, height);    }}

And thanks very much to this post: The-mystery-of-androids-full-screen-dialog-fragments

@Overridepublic void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setStyle(DialogFragment.STYLE_NORMAL,             android.R.style.Theme_Black_NoTitleBar_Fullscreen);}

Try switching to a LinearLayout instead of RelativeLayout. I was targeting the 3.0 Honeycomb api when testing.

public class FragmentDialog extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.main);    Button button = (Button) findViewById(R.id.show);    button.setOnClickListener(new OnClickListener() {        public void onClick(View v) {            showDialog();        }    });}@Overridepublic void onSaveInstanceState(Bundle outState) {    super.onSaveInstanceState(outState);}void showDialog() {    FragmentTransaction ft = getFragmentManager().beginTransaction();    DialogFragment newFragment = MyDialogFragment.newInstance();    newFragment.show(ft, "dialog");}public static class MyDialogFragment extends DialogFragment {    static MyDialogFragment newInstance() {        MyDialogFragment f = new MyDialogFragment();        return f;    }    @Override    public View onCreateView(LayoutInflater inflater, ViewGroup container,        Bundle savedInstanceState) {        View v = inflater.inflate(R.layout.fragment_dialog, container, false);        return v;    }}}

and the layouts: fragment_dialog.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout     xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:minWidth="1000dp"      android:minHeight="1000dp">  </LinearLayout> 

main.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical"     android:layout_width="match_parent"     android:layout_height="match_parent"    android:background="#ffffff">    <Button android:id="@+id/show"        android:layout_width="wrap_content"         android:layout_height="wrap_content"        android:layout_weight="0"        android:text="show">    </Button></LinearLayout>
