How to create a DialogFragment without title?

Question

I'm creating a DialogFragment to show some help messages regarding my app. Everything works fine besides one thing: There is a black stripe at the top of the window that shows the DialogFragment, that I presume is reserved for the title, something I don't want to use.

This is specially painful since my custom DialogFragment uses a white background, so the change is way too notorious to be left aside.

Let me show you this in a more graphical manner:

Now the XML code for my DialogFragment is as follows:

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="fill_parent"     android:layout_height="fill_parent">      <LinearLayout         android:id="@+id/holding"          android:orientation="vertical"          android:layout_width="fill_parent"          android:layout_height="fill_parent"         android:background="@drawable/dialog_fragment_bg"         >         <!-- Usamos un LinearLayout para que la imagen y el texto esten bien alineados -->         <LinearLayout             android:id="@+id/confirmationToast"              android:orientation="horizontal"              android:layout_width="wrap_content"              android:layout_height="wrap_content"             >              <TextView android:id="@+id/confirmationToastText"              android:layout_width="wrap_content"             android:layout_height="fill_parent"              android:text="@string/help_dialog_fragment"             android:textColor="#AE0000"             android:gravity="center_vertical"             />          </LinearLayout>         <LinearLayout             android:id="@+id/confirmationButtonLL"              android:orientation="horizontal"              android:layout_width="fill_parent"              android:layout_height="fill_parent"             android:gravity="center_horizontal"             >                 <Button android:id="@+id/confirmationDialogButton"                 android:layout_width="wrap_content"                 android:layout_height="wrap_content"                 android:gravity="center"                 android:layout_marginBottom="60dp"                 android:background="@drawable/ok_button">             </Button>         </LinearLayout>     </LinearLayout> </ScrollView> 

And the code of the class that implements the DialogFragment:

public class HelpDialog extends DialogFragment {      public HelpDialog() {         // Empty constructor required for DialogFragment     }      @Override     public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {         //Inflate the XML view for the help dialog fragment         View view = inflater.inflate(R.layout.help_dialog_fragment, container);         TextView text = (TextView)view.findViewById(R.id.confirmationToastText);         text.setText(Html.fromHtml(getString(R.string.help_dialog_fragment)));         //get the OK button and add a Listener         ((Button) view.findViewById(R.id.confirmationDialogButton)).setOnClickListener(new OnClickListener() {             public void onClick(View v) {                  // When button is clicked, call up to owning activity.                 HelpDialog.this.dismiss();              }          });         return view;     }  } 

And the creation process in the main Activity:

/**  * Shows the HelpDialog Fragment  */ private void showHelpDialog() {     android.support.v4.app.FragmentManager fm = getSupportFragmentManager();     HelpDialog helpDialog = new HelpDialog();     helpDialog.show(fm, "fragment_help"); } 

I really don't know if this answer, related with a Dialog, fits here also Android: How to create a Dialog without a title?

How can I get rid of this title area?

Answer 1

Just add this line of code in your HelpDialog.onCreateView(...)

getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE); 

This way you're explicitly asking to get a window without title :)

EDIT

As @DataGraham and @Blundell pointed out on the comments below, it's safer to add the request for a title-less window in the onCreateDialog() method instead of onCreateView(). This way you can prevent ennoying NPE when you're not using your fragment as a Dialog:

@Override public Dialog onCreateDialog(Bundle savedInstanceState) {   Dialog dialog = super.onCreateDialog(savedInstanceState);    // request a window without the title   dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);   return dialog; } 

Answer 2

Dialog fragment has setStyle method, which should be called before view creation Java Doc. Also style of the dialog can be set with the same method

public static MyDialogFragment newInstance() {         MyDialogFragment mDialogFragment = new MyDialogFragment();         //Set Arguments here if needed for dialog auto recreation on screen rotation         mDialogFragment.setStyle(DialogFragment.STYLE_NO_TITLE, 0);         return mDialogFragment; }
