图像不从自定义URL信息窗口加载在Android中使用毕加索的图像加载库 [英] image not loading from URL in custom infoWindow using Picasso image loading library in android

问题描述

我想自定义信息窗口从URL加载图像时的标记，用户点击。我可以加载其他的细节，但图像没有加载INT它。我使用的毕加索库来帮我这个忙。我搜索到很多相关的话题，看到了解决方案，但无法理解适用于解决我的问题，这解决方案。我使用的是Web服务调用来获取所需的数据。

I am trying to load an image from the URL in custom infoWindow when the user click on the marker. I was able to load the other details but the image is not loading int it. i'm using Picasso library to do this for me. I have search many related topics and see the solutions but was not able to understand which solution to apply to solve my problem. I am using an web service call to get the required data.

这是我的code：

  @Override
        public View getInfoContents(Marker arg0) {

            //marker.showInfoWindow();
            return null;
        }

        @Override
        public View getInfoWindow(Marker arg0) 
        {

            View v = getLayoutInflater().inflate(R.layout.map_infowindow, null);


             for(int i=0 ; i<lstMain.size();i++)
                {
                    Pojo b=lstMain.get(i);
                    double slat= Double.parseDouble(b.getLatitude());
                    double slng= Double.parseDouble(b.getLongitude());

                    double lat= Math.round(slat*100000.0)/100000.0;
                    double lng= Math.round(slng*100000.0)/100000.0;

                    String s1=String.valueOf(lat);
                    String s2=String.valueOf(lng);

                    Log.v("comparing latilongi pojo===>", lat+" , "+lng);
                    Log.v("comparing latilongi marker===>", Clickedlatitude+" , "+Clickedlongitude);

                    if(s1.equals(String.valueOf(Clickedlatitude)) && s2.equals(String.valueOf(Clickedlongitude)))
                    {
                        txtDname=(TextView)v.findViewById(R.id.infoDoctorName);
                        txtDspe=(TextView)v.findViewById(R.id.infoDoctorSpe);
                        txtDaddress=(TextView)v.findViewById(R.id.infoDoctorAddress);
                        imgUrl=(ImageView)v.findViewById(R.id.infoDoctorImage);
                        String url=b.getPhotoURL();

                        txtDname.setText(b.getDoctorName());
                        txtDspe.setText(b.getSpecialization());
                        txtDaddress.setText(b.getAddress1()+" , "+b.getAddress2());


                        Picasso.with(MapActivity.this)
                        .load(url)
                        .placeholder(R.drawable.ic_launcher)
                        .error(R.drawable.ic_launcher).resize(50, 50)
                        .into(imgUrl);


                    }

                }
            return v;
        }

我已经看到了这些解决方案，但不明白到底是什么将解决我的问题：

推荐答案

您可以使用一个毕加索回调的onSuccess加载图像，像这样

You can use a Picasso Callback onsuccess loading the image, like this

if (image != null) {
   Picasso.with(getApplicationContext())
          .load(image)
          .placeholder(R.drawable.ic_launcher)
          .into(i, new MarkerCallback(marker));
}

和创建一个新类来处理毕加索回调这样MarkerCallback.java

and create a new class to handle the Picasso Callback like this MarkerCallback.java

public class MarkerCallback implements Callback {
   Marker marker=null;

   MarkerCallback(Marker marker) {
     this.marker=marker;
   }

   @Override
   public void onError() {
     Log.e(getClass().getSimpleName(), "Error loading thumbnail!");
   }

   @Override
   public void onSuccess() {
     if (marker != null && marker.isInfoWindowShown()) {
       marker.hideInfoWindow();
       marker.showInfoWindow();
     }
   }
}
