Android 谷歌地图多边形点击事件

Question

<分区>

Answer 1

我遇到了同样的问题。 onMapClickListener 不会在用户点击多边形时调用，它只会在其他叠加层(例如多边形)未处理点击事件时调用。正如您所见，Polygon 会处理它 - GM 将多边形移动到屏幕中心。并且事件没有传递给onMapClickListener，仅此而已。 为了解决这个问题，我在 GM 处理点击事件之前拦截它们，在 View 包装 MapFragment 中，如所述 here ，将屏幕坐标中的点击点投影到 map ，然后检查它是否在 map 上的多边形内，如所述here (其他答案也说明了这一点)

相关代码:

public class MySupportMapFragment extends SupportMapFragment {
private View mOriginalContentView;
private TouchableWrapper mTouchView;
private BasicMapActivity mActivity;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mActivity = (BasicMapActivity) getActivity();
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup parent,
        Bundle savedInstanceState) {
    mOriginalContentView = super.onCreateView(inflater, parent,
            savedInstanceState);
    mTouchView = new TouchableWrapper();
    mTouchView.addView(mOriginalContentView);
    return mTouchView;
}

@Override
public View getView() {
    return mOriginalContentView;
}

class TouchableWrapper extends FrameLayout {

    public TouchableWrapper() {
        super(mActivity);
    }

    @Override
  public boolean dispatchTouchEvent(MotionEvent event) {
    switch (event.getAction()) {
      case MotionEvent.ACTION_DOWN:
          break;
      case MotionEvent.ACTION_UP: {
          int x = (int) event.getX();
          int y = (int) event.getY();
          mActivity.tapEvent(x,y);
          break;
      }
    }
    return super.dispatchTouchEvent(event);
  }
}

}

基本 map Activity :

public void tapEvent(int x, int y) {
    Log.d(TAG,String.format("tap event x=%d y=%d",x,y));
    if(!isEditMode()) {
        Projection pp = mMap.getProjection();
        LatLng point = pp.fromScreenLocation(new Point(x, y));
        for (Shape ss : mPolygons) {
            if(ss.isPointInPolygon(point)) {
                ss.mMarkers.get(0).marker.showInfoWindow();
            }
        }
    }
}

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_map);
}
