问题描述

下面就是我如何添加标记地图

Here is how i am adding marker to map

map.addMarker(new MarkerOptions()
                    .position(model.getLatLongfromService())
                    .title(model.getCoupon_name())
                    .snippet(model.getCoupon_id())
                    .icon(BitmapDescriptorFactory.fromFile(DataHolder.imageUrl
                            + model.getCoupon_image())));

• 我越来越coupon_image格式如下： http://www.xyz.com/coupon21 .JPG **

  我收到此错误当u运行我的应用程序。

  推荐答案

  我认为这个问题是该方法BitmapDesc​​riptorFactory.fromFile使用参数字符串的文件名，从而重新presents的文件名（图像）加载。
  您提供的图像的HTTP URL（ http://test.xyz.de/uploads /company_logo/sample-logo-110x60.jpg ）代替它。

  I think the problem is that method BitmapDescriptorFactory.fromFile uses parameter String fileName, which represents name of the file(image) to load. You supply image's http url (http://test.xyz.de/uploads/company_logo/sample-logo-110x60.jpg) instead of it.

  您可能需要先下载图像，然后使用BitmapDesc​​riptorFactory.fromBitmap;

  You probably need to download the image first and then use BitmapDescriptorFactory.fromBitmap;

  编辑：
  要下载图片，你可以使用一些AsyncTask的像这样的例子：

  To download image, you can use some AsyncTask like this for example:

      AsyncTask<String, Void, Bitmap> loadImageTask = new AsyncTask<String, Void, Bitmap>(){
          @Override
          protected Bitmap doInBackground(String... params) {
              Bitmap bmImg = null;
              try { 
                  URL url = new URL(params[0]);
                  HttpURLConnection conn = (HttpURLConnection) url.openConnection();   
                  conn.setDoInput(true);   
                  conn.connect();     
                  InputStream is = conn.getInputStream();
                  bmImg = BitmapFactory.decodeStream(is); 
              }
              catch (IOException e)
              {       
                  e.printStackTrace(); 
                  bmImg = null;
              }
  
              return bmImg; 
          }
  
          @Override
          protected void onPostExecute(Bitmap result) {
              super.onPostExecute(result);
              // TODO: do what you need with resulting bitmap - add marker to map
          }
      };
  

  这时别忘了适当的参数来执行的AsyncTask - 包含图像的URL字符串数组下载：

  then don't forget to execute asynctask with proper parameter - String array containing url of image to download:

  loadImageTask.execute(new String[]{yourImageUrl});
