安卓抽屜和谷歌地圖

Question

嗨無盡的論壇和嘗試我想我會需要更多的幫助。

我需要結合我的應用程序中的兩個功能： 1. Android抽屜。 2.谷歌地圖。

的想法是，我的應用程序的「主」屏幕是一張地圖，抽屜會幫助我改變設置，個人文件等..

所以，問題是什麼是最好的方式來結合他們？ 我的意思是我不想每次返回地圖時重新打開地圖（我有一個地圖數據庫，我不想每次都重新加載它）。我希望抽屜通過所有屏幕出現。

任何想法？

到目前爲止我的代碼：（除了與他們的名字空白頁其它碎片） 主要業務的xml：

<?xml version="1.0"?> 
    <android.support.v4.widget.DrawerLayout android:layout_height="match_parent" android:layout_width="match_parent" android:id="@+id/drawer_layout" xmlns:android="http://schemas.android.com/apk/res/android"> 
    <!-- <?xml version="1.0" encoding="utf-8"?> <fragment xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/map" android:layout_width="match_parent" android:layout_height="match_parent" android:name="com.google.android.gms.maps.MapFragment"/> --> 
    <FrameLayout android:layout_height="match_parent" android:layout_width="match_parent" android:id="@+id/content_frame"/> 
    <ListView android:layout_height="match_parent" android:layout_width="240dp" android:id="@+id/left_drawer" android:background="#fff" android:dividerHeight="0dp" android:divider="@android:color/transparent" android:choiceMode="singleChoice" android:layout_gravity="start"/> 
    </android.support.v4.widget.DrawerLayout>

     menu = new String[]{"Home","Android","Windows","Linux","Raspberry Pi","WordPress","Videos","Contact Us"}; 
     dLayout = (DrawerLayout) findViewById(R.id.drawer_layout); 
     dList = (ListView) findViewById(R.id.left_drawer); 
     adapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,menu); 
     dList.setAdapter(adapter); 
     dList.setSelector(android.R.color.holo_blue_dark); 
     dList.setOnItemClickListener(new OnItemClickListener(){ 
      @Override 
      public void onItemClick(AdapterView<?> arg0, View v, int position, long id) { 
       dLayout.closeDrawers(); 
       Bundle args = new Bundle(); 
       args.putString("Menu", menu[position]); 
       Fragment detail = new DetailFragment(); 

        if(position == 0){ 
    //      if(map == null){ 
           map = new MyMapFragment(); 
    //      } 
         detail = map; 
        } 
        detail.setArguments(args); 
        FragmentManager fragmentManager = getFragmentManager(); 
      fragmentManager.beginTransaction().replace(R.id.content_frame,detail).commit(); 
        } 
      }); 
     } 
    }

我能夠通過使用2個活動解決此問題： 1 - 帶地圖的抽屜。帶有其他窗口框架的抽屜。這兩個活動都繼承了一些基本的Drawer類。
