我有下表:

+--------+----------+---------+---------+---------
|  From  |    To    |Departure| Arrival |   ID   | 
+--------+----------+---------+---------+---------
|   A    |    B     |   0900  |   0930  |   1    | 
+--------+----------+---------+---------+---------
|   C    |    D     |   1000  |   1030  |   2    | 
+--------+----------+---------+---------+---------
|   B    |    C     |   1100  |   1130  |   3    | 
+--------+----------+---------+---------+---------
|   D    |    E     |   1200  |   1230  |   4    | 
+--------+----------+---------+---------+---------
|   C    |    D     |   1300  |   1330  |   5    | 
+--------+----------+---------+---------+---------

• 出发/到达时间和身份证总是在上升;
  
• C_D可以前后发现B_C. …

我正在创建这样的标记:

            Marker MO =  mMap.addMarker(new MarkerOptions()
                .position(latLng)
                .draggable(true)
                .icon(BitmapDescriptorFactory.fromBitmap(icon))
        );

            Marker M2 =  mMap.addMarker(new MarkerOptions()
                .position(latLng)
                .draggable(true)
                .icon(BitmapDescriptorFactory.fromBitmap(icon2))
        );

我希望在每个拖放时得到它的坐标,但是当使用它时:

             mMap.setOnMarkerDragListener(new OnMarkerDragListener() {

            @Override
            public void onMarkerDragStart(Marker M0) {  }

            @Override
            public void onMarkerDragEnd(Marker M0) {

                LatLng pos = M0.getPosition();


                TextView err = (TextView)findViewById(R.id.text1);
                err.setText("M0" + pos.latitude + "," + pos.longitude);

            }

            @Override
            public void onMarkerDrag(Marker M0) {     }

        });



        mMap.setOnMarkerDragListener(new OnMarkerDragListener() {

            @Override
            public void onMarkerDragStart(Marker M2) {  }

            @Override
            public void onMarkerDragEnd(Marker M2) {

                LatLng pos2 = M2.getPosition(); …
