Drawerlayout +谷歌地圖會導致死機

Question

我堅持抽屜佈局，我嘗試實施谷歌地圖上的抽屜項按下時1 它類似於像什麼，我在這裏找到：Google Maps V2 + Drawer Layout

我試圖重現他做了什麼，並且把我推向了正確的方向。

更新

我提出 「setUpMapIfNeeded」 和 「SetUpMap」 到MapFragment並移除了類的靜態。 Google地圖現在可以工作，但在嘗試導航到抽屜導航中的片段後崩潰。

有人知道如何幫助我嗎？我非常感謝！

基本的東西

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    mTitle = mDrawerTitle = getTitle(); 
    mMenuTitles = getResources().getStringArray(R.array.menu_array); 
    mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout); 
    mDrawerList = (ListView) findViewById(R.id.left_drawer); 

    // set a custom shadow that overlays the main content when the drawer opens 
    mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START); 
    // set up the drawer's list view with items and click listener 
    mDrawerList.setAdapter(new ArrayAdapter<String>(this, 
      R.layout.drawer_list_item, mMenuTitles)); 
    mDrawerList.setOnItemClickListener(new DrawerItemClickListener()); 

    // enable ActionBar app icon to behave as action to toggle nav drawer 
    getActionBar().setDisplayHomeAsUpEnabled(true); 
    getActionBar().setHomeButtonEnabled(true); 

    // ActionBarDrawerToggle ties together the the proper interactions 
    // between the sliding drawer and the action bar app icon 
    mDrawerToggle = new ActionBarDrawerToggle(
      this,     /* host Activity */ 
      mDrawerLayout,   /* DrawerLayout object */ 
      R.drawable.ic_drawer, /* nav drawer image to replace 'Up' caret */ 
      R.string.drawer_open, /* "open drawer" description for accessibility */ 
      R.string.drawer_close /* "close drawer" description for accessibility */ 
      ) { 
     public void onDrawerClosed(View view) { 
      getActionBar().setTitle(mTitle); 
      invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu() 
     } 

     public void onDrawerOpened(View drawerView) { 
      getActionBar().setTitle(mDrawerTitle); 
      invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu() 
     } 
    }; 
    mDrawerLayout.setDrawerListener(mDrawerToggle); 

    if (savedInstanceState == null) { 
     selectItem(0); 
    } 
} 

我的選擇

Fragment mapFragment; 
Fragment fragment; 
private void selectItem(int position) { 
    FragmentManager fragmentManager = getFragmentManager(); 

    if (position == 0) { 
     if (mapFragment == null) { 
      mapFragment = new MapFragment(); 
     } 
     Bundle args = new Bundle(); 

     args.putInt(MapFragment.ARG_NUMBER, position); 
     mapFragment.setArguments(args); 

     fragmentManager.beginTransaction().replace(R.id.content_frame, mapFragment).commit(); 

    } else if (position == 1) { 
     if (fragment == null) { 
      fragment = new InformationFragment(); 
     } 
     Bundle args = new Bundle(); 

     args.putInt(InformationFragment.ARG_NUMBER, position); 
     fragment.setArguments(args); 

     fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).commit(); 
    } 

    // update selected item and title, then close the drawer 
    mDrawerList.setItemChecked(position, true); 
    setTitle(mMenuTitles[position]); 
    mDrawerLayout.closeDrawer(mDrawerList); 
} 

我MapFragments（抽屜第1項）

public class MapFragment extends Fragment { 

    public static final String ARG_NUMBER = "arg_number"; 

    public MapFragment() { 
     // Empty constructor required for fragment subclasses 
    } 

    private void setUpMapIfNeeded() { 
     // Do a null check to confirm that we have not already instantiated the map. 
     if (mMap == null) { 
      // Try to obtain the map from the SupportMapFragment. 
      mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)) 
        .getMap(); 
      // Check if we were successful in obtaining the map. 
      if (mMap != null) { 
       setUpMap(); 
      } 
     } 
    } 

    private void setUpMap() { 
     LatLng museum = new LatLng(52.360011, 4.885216); 

     mMap.setBuildingsEnabled(true); 
     mMap.setMyLocationEnabled(false); 

     // Construct a CameraPosition focusing on Mountain View and animate the camera to that position. 
     CameraPosition cameraPosition = new CameraPosition.Builder() 
       .target(museum)    // Sets the center of the map to Mountain View 
       .zoom(19)     // Sets the zoom 
       .bearing(90)    // Sets the orientation of the camera to east 
       .tilt(30)     // Sets the tilt of the camera to 30 degrees 
       .build();     // Creates a CameraPosition from the builder 

     mMap.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition)); 

     CameraUpdate upd = CameraUpdateFactory.newLatLngZoom(new LatLng(52.360011, 4.885216), 18); 
     mMap.moveCamera(upd); 
    } 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
      Bundle savedInstanceState) { 

     View rootView = inflater.inflate(R.layout.maps_fragment, container, false); 
     int i = getArguments().getInt(ARG_NUMBER); 

     String title = getResources().getStringArray(R.array.menu_array)[i]; 
     setUpMapIfNeeded(); 
     getActivity().setTitle(title); 
     return rootView; 
    } 
}

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
android:orientation="vertical" >

     android:paddingRight="20dp" 
     android:text="Lorem Ipsum is simply dummy text of the printing and typesetting industry.

嘗試修改喜歡你的代碼add fragmentManager.executePendingTransactions（）;提交後

Fragment mapFragment; 
Fragment fragment; 
private void selectItem(int position) { 
    FragmentManager fragmentManager = getFragmentManager(); 

    if (position == 0) { 
     if (mapFragment == null) { 
      mapFragment = new MapFragment(); 
     } 
     Bundle args = new Bundle(); 

     args.putInt(MapFragment.ARG_NUMBER, position); 
     mapFragment.setArguments(args); 

     fragmentManager.beginTransaction().replace(R.id.content_frame, mapFragment).commit(); 

    } else if (position == 1) { 
     if (fragment == null) { 
      fragment = new InformationFragment(); 
     } 
     Bundle args = new Bundle(); 

     args.putInt(InformationFragment.ARG_NUMBER, position); 
     fragment.setArguments(args); 

     fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).commit(); 
    } 

    fragmentManager.executePendingTransactions(); 
    // update selected item and title, then close the drawer 
    mDrawerList.setItemChecked(position, true); 
    setTitle(mMenuTitles[position]); 
    mDrawerLayout.closeDrawer(mDrawerList); 
}
