Question

我在我的android项目的同一个java文件中声明了一个类，我的代码由于某种原因不能识别它吗？当我在模拟器中运行它时，我在运行时得到一个NoClassDefFoundError。

当我尝试在模拟器中运行我的Android应用程序时，我收到以下错误：

这是我的代码：

AsyncOverlay(LoggerMap loggermap, Handler handler)
{
  mLoggerMap = loggermap;
  mHandler = handler;
  mWidth = 1;
  mHeight = 1;
  mPaint = new Paint();
  mActiveZoomLevel = -1;
  mActiveBitmap = Bitmap.createBitmap(mWidth, mHeight, Bitmap.Config.ARGB_8888);
  mActiveTopLeft = new GeoPoint(0, 0);
  mActivePointTopLeft = new Point();
  mCalculationBitmap = Bitmap.createBitmap(mWidth, mHeight, Bitmap.Config.ARGB_8888);

  mOsmOverlay = new SegmentOsmOverlay(mLoggerMap.getActivity(), mLoggerMap, this);
  mMapQuestOverlay = new SegmentMapQuestOverlay(this);
}

这是我的班级：

   static class SegmentOsmOverlay extends org.osmdroid.views.overlay.Overlay {
   AsyncOverlay mSegmentOverlay;
  LoggerMap mLoggerMap;

  public SegmentOsmOverlay(Context ctx, LoggerMap map, AsyncOverlay segmentOverlay)
  {
     super(ctx);
     mLoggerMap = map;
     mSegmentOverlay = segmentOverlay;
  }

  public AsyncOverlay getSegmentOverlay()
  {
     return mSegmentOverlay;
  }

  @Override
  public boolean onSingleTapUp(MotionEvent e, org.osmdroid.views.MapView openStreetMapView)
  {
     int x = (int) e.getX();
     int y = (int) e.getY();
     GeoPoint tappedGeoPoint = mLoggerMap.fromPixels(x, y);
     return mSegmentOverlay.commonOnTap(tappedGeoPoint);
  }

  @Override
  protected void draw(Canvas canvas, org.osmdroid.views.MapView view, boolean shadow)
  {
     if (!shadow)
     {
        mSegmentOverlay.draw(canvas);
     }
  }
}

有什么建议吗？

尝试清理你的项目（项目 - ＆gt;干净......）然后刷新项目（右键单击项目名称 - > gt;刷新..）

请告诉我它是否有效。

当类已经在同一个java文件中声明时，NoClassDefFoundError
