自定義標記圖像不顯示在谷歌地圖

Question

位圖圖像不drawing.i不明白爲什麼圖像正在繪製作爲標記在谷歌maps.is有任何其他方式來定製谷歌地圖標記爲圖像 我不能理解圖像是否是越來越加載或不

final LatLng MELBOURNE = new LatLng(-37.813, 144.962); 

      final URL url = new URL(
        "http://indervilla.com/home/Mickey-Mouse-Cartoon-HD.jpg"); 
      HttpURLConnection conn = (HttpURLConnection) url.openConnection(); 
      conn.setDoInput(true); 
      conn.connect(); 
      InputStream is = conn.getInputStream(); 
      Bitmap bmImg = BitmapFactory.decodeStream(is); 

      Bitmap.Config conf = Bitmap.Config.ARGB_8888; 
      Bitmap bmp = Bitmap.createBitmap(80, 80, conf); 
      Canvas canvas1 = new Canvas(bmp); 

      // paint defines the text color, 
      // stroke width, size 
      Paint color = new Paint(); 
      color.setTextSize(20); 
      color.setColor(Color.RED); 
      color.setStrokeWidth(10); 

      // modify canvas 
      canvas1.drawBitmap(bmImg, -10, -10, color); 


      // add marker to Map 
      googleMap.addMarker(new MarkerOptions().position(MELBOURNE) 
        .icon(BitmapDescriptorFactory.fromBitmap(bmp)) 
        // Specifies the anchor to be at a particular point in the 
        // marker image. 
        .anchor(.5f, 1)); 

      CameraPosition cameraPosition = new CameraPosition.Builder() 
        .target(new LatLng(-37.813, 144.962)).zoom(15).build(); 

      googleMap.animateCamera(CameraUpdateFactory 
        .newCameraPosition(cameraPosition)); 

     } catch (Exception e) { 
      e.printStackTrace(); 
     } 

    } 

    @Override 
    protected void onResume() { 
     super.onResume(); 
     initilizeMap(); 
    } 

    /** 
    * function to load map If map is not created it will create it for you 
    * */ 
    private void initilizeMap() { 
     if (googleMap == null) { 
      googleMap = ((MapFragment) getFragmentManager().findFragmentById(
        R.id.map)).getMap(); 

      // check if map is created successfully or not 
      if (googleMap == null) { 
       Toast.makeText(getApplicationContext(), 
         "Sorry! unable to create maps", Toast.LENGTH_SHORT) 
         .show(); 
      } 
     } 
    } 

}

我建議你看一看的Maps Utils Library。它有很多整潔的功能，包括相對容易的自定義Marker創建和插入到GoogleMap。
