Fragment placed on top of NavigationDrawer

问题

I'm trying to add a PreferenceFragmentin my application. The problem is, it's auto placed on top of my NavigationDrawer.

public class SetPreferenceActivity extends Activity {

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  // TODO Auto-generated method stub
  super.onCreate(savedInstanceState);
  setContentView(R.layout.settings);
  navigationDrawer(); // Loads the NavigationDrawer

  getFragmentManager().beginTransaction().replace(android.R.id.content,
               new Settings()).commit();

 }

As you can see I load the "SettingsFragment" and replace the content with it? (I'm unsure) but it places it on top of everything else.. Here's my Settings fragment.

public class Settings extends PreferenceFragment  {
    static final String TAG = "MAIN";

    @Override
    public void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
         addPreferencesFromResource(R.xml.preferences);

    }

Everything work as expected, BUT the PreferenceFragment are loaded in front, covering up the NavigationDrawer slideout, I tried calling bringToFront(); on the listview, with no luck.

A picture for reference :

Is it possible to tell the fragment to load behind the listview? I also tought about loading the fragment in a ViewPager, but I get an error that the Pager Adapter wont accept fragments of type PreferenceFragment.

Don't replace android.R.id.content, use the the id of the FrameLayout you have in the layout that contains your DrawerLayout.

In addition to what adneal said (in case others have the same problem):

The Activity which calls the PreferenceFragment needs to have the setContentView() method if you extend the Activity with your NavigationDrawer:

public class SetPreferenceActivity extends MyNavigationDrawer {

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

  setContentView(R.layout.settings);

  getFragmentManager().beginTransaction().replace(R.id.drawer_frame_layout,
               new Settings()).commit();    
 }

And the settings.xml should only contain a FrameLayout:

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
             android:layout_width="match_parent"
             android:layout_height="match_parent"/>

I had same issue and i resolved it by replacing android.R.id.content to R.id.container.
