title: How to create a DialogFragment without title?
body: <p>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.</p>
  
  <p>This is specially painful since my custom DialogFragment uses a white background, so the change is way too notorious to be left aside.</p>
  
  <p>Let me show you this in a more graphical manner:</p>
  
  <p><img src="https://i.stack.imgur.com/iGWC5.png" alt="enter image description here"></p>
  
  <p>Now the XML code for my DialogFragment is as follows:</p>
  
  <pre><code>&lt;ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="fill_parent"
      android:layout_height="fill_parent"&gt;
  
      &lt;LinearLayout
          android:id="@+id/holding" 
          android:orientation="vertical" 
          android:layout_width="fill_parent" 
          android:layout_height="fill_parent"
          android:background="@drawable/dialog_fragment_bg"
          &gt;
          &lt;!-- Usamos un LinearLayout para que la imagen y el texto esten bien alineados --&gt;
          &lt;LinearLayout
              android:id="@+id/confirmationToast" 
              android:orientation="horizontal" 
              android:layout_width="wrap_content" 
              android:layout_height="wrap_content"
              &gt;
  
              &lt;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"
              /&gt;
  
          &lt;/LinearLayout&gt;
          &lt;LinearLayout
              android:id="@+id/confirmationButtonLL" 
              android:orientation="horizontal" 
              android:layout_width="fill_parent" 
              android:layout_height="fill_parent"
              android:gravity="center_horizontal"
              &gt;    
              &lt;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"&gt;
              &lt;/Button&gt;
          &lt;/LinearLayout&gt;
      &lt;/LinearLayout&gt;
  &lt;/ScrollView&gt;
  </code></pre>
  
  <p>And the code of the class that implements the DialogFragment:</p>
  
  <pre><code>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;
      }
  
  }
  </code></pre>
  
  <p>And the creation process in the main Activity:</p>
  
  <pre><code>/**
   * Shows the HelpDialog Fragment
   */
  private void showHelpDialog() {
      android.support.v4.app.FragmentManager fm = getSupportFragmentManager();
      HelpDialog helpDialog = new HelpDialog();
      helpDialog.show(fm, "fragment_help");
  }
  </code></pre>
