SlidingMenu：「getActionBar（）。setHomeButtonEnabled（true）;」未採取

Question

HomeButton未啓用切換菜單！

它在我的測試應用程序內，但不是我想要的應用程序。

這裏NavigationDrawerActivity：

public class NavigationDrawerActivity extends Activity{ 

    protected String[] drawerList; 
    protected ListView drawerView; 
    protected DrawerLayout drawerLayout; 
    protected Context context; 

    private ActionBarDrawerToggle mDrawerToggle; 

    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     context=this; 

     drawerView=(ListView) findViewById(R.id.left_drawer); 
     drawerLayout=(DrawerLayout) findViewById(R.id.drawer_layout); 


     //Android doesn't accept the ListView.setAdapter here..!? 
     drawerList = getResources().getStringArray(R.array.nav_drawer_items); 

     ((ListView) findViewById(R.id.left_drawer)).setAdapter(new ArrayAdapter<String>(this, R.layout.menu_list_item, drawerList)); 

     drawerView.setOnItemClickListener(new OnItemClickListener() { 
      @Override 
      public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 
       Intent menu; 
       switch (position) { 
       case 0: 
        drawerLayout.closeDrawer(drawerView); 
        if(context.getClass().equals(ActivityMain.class)) { 
         Log.i("menu", "same Actvity"); 
         break; 
        } 
        menu = new Intent(context, ActivityMain.class); 
        menu.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
        startActivity(menu); 
        overridePendingTransition(R.anim.in, R.anim.out); 
        break; 
       default: 
        drawerLayout.closeDrawer(drawerView); 
        //new RalaAlertToast(context, "default"); 
        break; 
       } 
      } 
     }); 

     mDrawerToggle = new ActionBarDrawerToggle((Activity) context, drawerLayout, R.drawable.ic_drawer, R.string.drawer_open, R.string.drawer_close) { 
      /** Called when a drawer has settled in a completely closed state. */ 
      public void onDrawerClosed(View view) { 
       super.onDrawerClosed(view); 
       getActionBar().setTitle(R.string.app_name); 
      } 

      /** Called when a drawer has settled in a completely open state. */ 
      public void onDrawerOpened(View drawerView) { 
       super.onDrawerOpened(drawerView); 
       getActionBar().setTitle(R.string.app_name); 
      } 
     }; 

     drawerLayout.setDrawerListener(mDrawerToggle); 

     getActionBar().setDisplayHomeAsUpEnabled(true); 
     actionAPI14(); 
    } 

    @TargetApi(14) 
    private void actionAPI14() { 
     if(Build.VERSION.SDK_INT>=14) {//disabled Target Check 
      getActionBar().setHomeButtonEnabled(true); 
     } 
    } 

    @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); 
     mDrawerToggle.onConfigurationChanged(newConfig); 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     // Pass the event to ActionBarDrawerToggle, if it returns 
     // true, then it has handled the app icon touch event 
     if (mDrawerToggle.onOptionsItemSelected(item)) { 
      return true; 
     } 
     // Handle your other action bar items... 

     return super.onOptionsItemSelected(item); 
    } 

    @Override 
    public boolean onKeyDown(int keyCode, KeyEvent event) { 
     if ((keyCode == KeyEvent.KEYCODE_BACK)) { 
      if(! drawerLayout.isDrawerOpen(drawerView)) { 
       finish(); 
       System.exit(0); 
       return true; 
      }else{ 
       drawerLayout.closeDrawer(drawerView); 
      } 
     } 
     return false; 
    } 

    @Override 
    public boolean onKeyDown(int keyCode, KeyEvent event) { 
     if ((keyCode == KeyEvent.KEYCODE_BACK)) { 
      if(drawerLayout.isDrawerOpen(drawerView)) { 
       drawerLayout.closeDrawer(drawerView); 
       return true; 
      } 
     } 
     return false; 
    } 
} 

我讀過很多論壇和有關目標等網站...
但沒有任何幫助。
有什麼可能的原因？

我也發佈了它，他們正在尋找一種簡單的方法來製作自己的菜單。只是擴展了這個Claes。 （我搜索長，在我的測試應用它的工作沒有任何問題！）

確保，您在活動super.onOpionsItemSelected來電！
