El cajón de navegación se cierra al hacer clic

He implementado un cajón de navegación, pero tengo problemas para que funcione correctamente. Cuando hago clic en la posición 1 o 2, no se inicia el nuevo fragmento.

MainActivity.java

public class MainActivity extends Activity { private DrawerLayout mDrawerLayout; private ListView mDrawerList; private ActionBarDrawerToggle mDrawerToggle; // nav drawer title private CharSequence mDrawerTitle; // used to store app title private CharSequence mTitle; // slide menu items private String[] navMenuTitles; private TypedArray navMenuIcons; private ArrayList<NavDrawerItem> navDrawerItems; private NavDrawerListAdapter adapter; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Typeface tf = Typeface.createFromAsset(getAssets(),"Roboto-Light.ttf"); TextView title = (TextView) findViewById(R.id.appTitle); TextView newRecord = (TextView) findViewById(R.id.newRecord); TextView pastRecords = (TextView) findViewById(R.id.pastRecords); TextView statistics = (TextView) findViewById(R.id.statistics); TextView settings = (TextView) findViewById(R.id.settings); title.setTypeface(tf); newRecord.setTypeface(tf); pastRecords.setTypeface(tf); statistics.setTypeface(tf); settings.setTypeface(tf); newRecord.setOnClickListener(new OnClickListener() { @Override public void onClick(View v){ Intent i = new Intent(MainActivity.this, newRecord.class); startActivity(i); } }); pastRecords.setOnClickListener(new OnClickListener() { @Override public void onClick(View v){ Intent i = new Intent(MainActivity.this, history.class); startActivity(i); } }); statistics.setOnClickListener(new OnClickListener() { @Override public void onClick(View v){ Intent i = new Intent(MainActivity.this, statistics.class); startActivity(i); } }); /* * NavBar Starts Here */ mTitle = mDrawerTitle = getTitle(); // load slide menu items navMenuTitles = getResources().getStringArray(R.array.nav_drawer_items); // nav drawer icons from resources navMenuIcons = getResources() .obtainTypedArray(R.array.nav_drawer_icons); mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout); mDrawerList = (ListView) findViewById(R.id.list_slidermenu); navDrawerItems = new ArrayList<NavDrawerItem>(); // adding nav drawer items to array // Home navDrawerItems.add(new NavDrawerItem(navMenuTitles[0], navMenuIcons.getResourceId(0, -1))); // Find People navDrawerItems.add(new NavDrawerItem(navMenuTitles[1], navMenuIcons.getResourceId(1, -1))); // Photos navDrawerItems.add(new NavDrawerItem(navMenuTitles[2], navMenuIcons.getResourceId(2, -1))); // Communities, Will add a counter here navDrawerItems.add(new NavDrawerItem(navMenuTitles[3], navMenuIcons.getResourceId(3, -1), true, "22")); // Pages navDrawerItems.add(new NavDrawerItem(navMenuTitles[4], navMenuIcons.getResourceId(4, -1))); // What's hot, We will add a counter here navDrawerItems.add(new NavDrawerItem(navMenuTitles[5], navMenuIcons.getResourceId(5, -1), true, "50+")); // Recycle the typed array navMenuIcons.recycle(); // CLICK LISTENER FOR NAV MENU mDrawerList.setOnItemClickListener(new SlideMenuClickListener()); // setting the nav drawer list adapter adapter = new NavDrawerListAdapter(getApplicationContext(), navDrawerItems); mDrawerList.setAdapter(adapter); // enabling action bar app icon and behaving it as toggle button getActionBar().setDisplayHomeAsUpEnabled(true); getActionBar().setHomeButtonEnabled(true); mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.drawable.ic_drawer, //nav menu toggle icon R.string.app_name, // nav drawer open - description for accessibility R.string.app_name // nav drawer close - description for accessibility ){ public void onDrawerClosed(View view) { getActionBar().setTitle(mTitle); // calling onPrepareOptionsMenu() to show action bar icons invalidateOptionsMenu(); } public void onDrawerOpened(View drawerView) { getActionBar().setTitle(mDrawerTitle); // calling onPrepareOptionsMenu() to hide action bar icons invalidateOptionsMenu(); } }; mDrawerLayout.setDrawerListener(mDrawerToggle); if (savedInstanceState == null) { // on first time display view for first nav item displayView(0); } } // CLICK LISTENER STUFF /** * Slide menu item click listener * */ private class SlideMenuClickListener implements ListView.OnItemClickListener { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { // display view for selected nav drawer item displayView(position); Log.d("Listener", "" + position); } } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.main, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { // toggle nav drawer on selecting action bar app icon/title if (mDrawerToggle.onOptionsItemSelected(item)) { return true; } // Handle action bar actions click switch (item.getItemId()) { case R.id.action_settings: return true; default: return super.onOptionsItemSelected(item); } } /*** * Called when invalidateOptionsMenu() is triggered */ @Override public boolean onPrepareOptionsMenu(Menu menu) { // if nav drawer is opened, hide the action items boolean drawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList); menu.findItem(R.id.action_settings).setVisible(!drawerOpen); return super.onPrepareOptionsMenu(menu); } /** * Diplaying fragment view for selected nav drawer list item * */ private void displayView(int position) { // update the main content by replacing fragments Fragment fragment = null; switch (position) { case 0: fragment = new HomeFragment(); Log.d("displayView", "click HomeFragment"); break; case 1: fragment = new FindPeopleFragment(); break; /*case 2: fragment = new PhotosFragment(); break; case 3: fragment = new CommunityFragment(); break; case 4: fragment = new PagesFragment(); break; case 5: fragment = new WhatsHotFragment(); break;*/ default: break; } if (fragment != null) { FragmentManager fragmentManager = getFragmentManager(); fragmentManager.beginTransaction() .replace(R.id.frame_container, fragment).commit(); // update selected item and title, then close the drawer mDrawerList.setItemChecked(position, true); mDrawerList.setSelection(position); setTitle(navMenuTitles[position]); mDrawerLayout.closeDrawer(mDrawerList); } else { // error in creating fragment Log.e("MainActivity", "Error in creating fragment"); } } @Override public void setTitle(CharSequence title) { mTitle = title; getActionBar().setTitle(mTitle); } /** * When using the ActionBarDrawerToggle, you must call it during * onPostCreate() and onConfigurationChanged()... */ @Override protected void onPostCreate(Bundle savedInstanceState) { super.onPostCreate(savedInstanceState); // Sync the toggle state after onRestoreInstanceState has occurred. mDrawerToggle.syncState(); } @Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); // Pass any configuration change to the drawer toggls mDrawerToggle.onConfigurationChanged(newConfig); } } 

¿Alguien puede ver lo que estoy haciendo mal? Cuando hace clic en la vista de lista en el cajón, sólo cierra el cajón. No está registrando nada que tenga en su lugar.

No me di cuenta de esto, pero el contenedor principal debe venir antes del cajón de nav. Moví el ListView para el cajón nav al fondo de mi activity_main.xml y viola, funciona!
