源附件不包含该文件Layoutinflater.class

源

我想要编写使用谷歌地图API版本2
在调试应用程序崩溃的Android应用程序，当执行该指令：源附件不包含该文件Layoutinflater.class

 setContentView(R.layout.activity_poi_map);

这是错误：

the source attachment does not contain the source for the file Layoutinflater.class

我不明白其中的道理。在标题我导入全班

android.view.*

谢谢您的任何答案。

这是代码：

public class PoiMap extends FragmentActivity { 

    private GoogleMap pMap; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     Intent callerIntent = getIntent(); 
     final LatLng userCoord = callerIntent.getParcelableExtra("userCoord"); 
     final Poi poi = (Poi) callerIntent.getSerializableExtra("poi"); 

     setContentView(R.layout.activity_poi_map); 
     setUpMapIfNeeded(userCoord); 

     // Sets a callback that's invoked when the camera changes. 
     pMap.setOnCameraChangeListener(new OnCameraChangeListener() { 

      @Override 
      /* Only use the simpler method newLatLngBounds(boundary, padding) to generate 
      * a CameraUpdate if it is going to be used to move the camera *after* the map 
      * has undergone layout. During layout, the API calculates the display boundaries 
      * of the map which are needed to correctly project the bounding box. 
      * In comparison, you can use the CameraUpdate returned by the more complex method 
      * newLatLngBounds(boundary, width, height, padding) at any time, even before the 
      * map has undergone layout, because the API calculates the display boundaries 
      * from the arguments that you pass. 
      * @see com.google.android.gms.maps.GoogleMap.OnCameraChangeListener#onCameraChange(com.google.android.gms.maps.model.CameraPosition) 
      */ 
      public void onCameraChange(CameraPosition arg0) {

        .snippet(poi.getCategory()) 
        .icon(BitmapDescriptorFactory.fromResource(R.drawable.ic_star))); 

        Log.d("userCoord", userCoord.toString()); 
        Log.d("poiCoord", poiCoord.toString()); 

        double minY = Math.min(userCoord.latitude, poiCoord.latitude);

        // move camera 
        pMap.animateCamera(CameraUpdateFactory.newLatLngBounds(bounds, 40)); 

        // Remove listener to prevent position reset on camera move. 
        pMap.setOnCameraChangeListener(null); 
       } 
      } 
     }); 
    } 

    @Override

    }

这不是应用程序崩溃的原因，读取红色LogCat行堆栈跟踪。您所看到的仅仅意味着您没有将您的项目链接到Android源代码（这不需要编写应用程序）。 – Sam 2013-02-18 18:34:36
