Android應用程序崩潰Tabs和谷歌地圖

我使用ActionBar選項卡，有三個選項卡，第三個選項卡具有Google地圖。當我在第一和第三之間切換時，它在第一和第二之間崩潰，它也崩潰，但在第二和第三切換之間從不崩潰。我不知道爲什麼會發生這種情況。Android應用程序崩潰Tabs和谷歌地圖

我已添加日誌貓請參考它，並幫助我爲什麼是應用程序崩潰，同時切換標籤第二次 – AnonymousDev

好吧，讓我試試.. – AnonymousDev

感謝dainel它工作，但我不明白原因可以解釋我th原因？ – AnonymousDev

，以確保你不會遇到這個錯誤的最好辦法是使片段延長SupportMapFragment代替嵌套一個內次e片段。

我剛剛得到這個工作，使用ViewPager與FragmentPagerAdapter與地圖作爲其中一個選項卡。

這裏是一般結構，注意有沒有需要重寫onCreateView()方法，而且也沒有必要誇大任何佈局的xml：

public class MyMapFragment extends SupportMapFragment implements OnMapReadyCallback { 

    private GoogleMap mMap; 
    private Marker marker; 


    public MyMapFragment() { 
    } 

    @Override 
    public void onResume() { 
     super.onResume(); 

     Log.d("MyMap", "onResume"); 
     setUpMapIfNeeded(); 
    } 

    private void setUpMapIfNeeded() { 

     if (mMap == null) { 

      Log.d("MyMap", "setUpMapIfNeeded"); 

      getMapAsync(this); 
     } 
    } 

    @Override 
    public void onMapReady(GoogleMap googleMap) { 
     Log.d("MyMap", "onMapReady"); 
     mMap = googleMap; 
     setUpMap(); 
    } 

    private void setUpMap() { 

     mMap.setMyLocationEnabled(true); 
     mMap.setMapType(GoogleMap.MAP_TYPE_HYBRID); 
     mMap.getUiSettings().setMapToolbarEnabled(false); 


     mMap.setOnMapClickListener(new GoogleMap.OnMapClickListener() { 

      @Override 
      public void onMapClick(LatLng point) { 

       Log.d("MyMap", "MapClick"); 

       //remove previously placed Marker 
       if (marker != null) { 
        marker.remove(); 
       } 

       //place marker where user just clicked 
       marker = mMap.addMarker(new MarkerOptions().position(point).title("Marker") 
         .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_MAGENTA))); 

       Log.d("MyMap", "MapClick After Add Marker"); 

      } 
     }); 

    } 


}

結果：

原因運行時異常：當應用程序是不是啓動它初始化所有並再次滑動到選項卡3即地圖選項卡，代碼正試圖創建另一個尚未銷燬的地圖片段，這導致了非法狀態異常，此兩種解決方案：

解決方案1：

public View onCreateView(LayoutInflater inflater, ViewGroup container, 
       Bundle savedInstanceState) { 
       ctx=getActivity(); 

       if (view != null) { 
        ViewGroup parent = (ViewGroup) view.getParent(); 
        if (parent != null) 
         parent.removeView(view); 
       } 
       try { 
        view = inflater.inflate(R.layout.nearbyplaces, container, false); 
       } catch (InflateException e) { 

       } 

//rest of code is same  
}

在此我們要更換由從父隨後再次加入移除第一現有片段..

解決方案2：這個人是最好的解決辦法：

public View onCreateView(LayoutInflater inflater, ViewGroup container, 
      Bundle savedInstanceState) { 
      ctx=getActivity(); 

      if (view == null) { 
    view = inflater.inflate(R.layout.nearbyplaces, container, false); 
      } 
//rest of code is same 
      return view; 


    }
