Android導航抽屜級別

我在Android中導航抽屜出現問題。所以這些代碼與我：Android導航抽屜級別

public class NavigationDrawer extends FragmentActivity { 
private String[] drawerListViewItems; 
private DrawerLayout drawerLayout; 
private ListView drawerListView; 
private ActionBarDrawerToggle actionBarDrawerToggle; 

protected DrawerLayout fullLayout; 
protected FrameLayout actContent; 

@Override 
public void setContentView(final int layoutResID) { 

    fullLayout = (DrawerLayout) getLayoutInflater().inflate(
      R.layout.navigation_drawer, null); // Your base layout here 
    actContent = (FrameLayout) fullLayout.findViewById(R.id.act_content); 
    getLayoutInflater().inflate(layoutResID, actContent, true); 
    super.setContentView(fullLayout); 
    drawerListViewItems = getResources().getStringArray(R.array.items); 
    drawerListView = (ListView) findViewById(R.id.left_drawer); 
    drawerListView.setAdapter(new ArrayAdapter<String>(this, 
      R.layout.drawer_listview_item, drawerListViewItems)); 
    drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout); 

    actionBarDrawerToggle = new ActionBarDrawerToggle(this, 
    drawerLayout, 
    R.drawable.ic_drawer, 
    R.string.drawer_open, 
    R.string.drawer_close 
    ); 
    drawerLayout.setDrawerListener(actionBarDrawerToggle); 
    getActionBar().setDisplayHomeAsUpEnabled(true); 
    drawerLayout.setDrawerShadow(R.drawable.drawer_shadow, 
      GravityCompat.START); 
    drawerListView.bringToFront(); 
    drawerListView.setOnItemClickListener(new DrawerItemClickListener()); 
} 

@Override 
public void onConfigurationChanged(Configuration newConfig) { 
    super.onConfigurationChanged(newConfig); 
    actionBarDrawerToggle.onConfigurationChanged(newConfig); 
} 

@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    if (actionBarDrawerToggle.onOptionsItemSelected(item)) { 
     return true; 
    } 
    return super.onOptionsItemSelected(item); 
} 

@Override 
protected void onPostCreate(Bundle savedInstanceState) { 
    super.onPostCreate(savedInstanceState); 
    actionBarDrawerToggle.syncState(); 
} 

private class DrawerItemClickListener implements 
     ListView.OnItemClickListener { 
    @Override 
    public void onItemClick(AdapterView parent, View view, int position, 
      long id) { 
     switch (position) { 
     } 
     drawerLayout.closeDrawer(drawerListView); 
    } 
} 
}

我的XML文件：

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@+id/drawer_layout" 
android:layout_width="match_parent" 
android:layout_height="match_parent" > 
<ListView 
    android:id="@+id/left_drawer" 
    android:layout_width="240dp" 
    android:layout_height="match_parent" 
    android:layout_gravity="start" 
    android:background="#111" 
    android:divider="#CCCCCC" 
    android:dividerHeight="0.5dp" 
    android:paddingLeft="16dp" 
    android:paddingRight="16dp" /> 

<FrameLayout 
    android:id="@+id/act_content" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical" > 
</FrameLayout> 

</android.support.v4.widget.DrawerLayout>

而且在那裏我宣佈了抽屜式導航欄項目的話字符串文件：

<string-array name="items"> 
    <item>Dashboard</item> 
    <item>Account</item> 
    <item>Setting</item> 
    <item>Recurring</item> 
    <item>Budget</item> 
</string-array>

但隨着這些代碼中，導航抽屜級別只有一個。我想要做的是在儀表板，設置和預算下仍然會有子項目。

我不知道如何修改它，這樣的導航抽屜可以採取在項目中的一個多層次。

在此先感謝。
