一张图像显示在我的应用程序上，另一张图像没有显示，但是都可以从浏览器访问。
我的免费主机中的这个未显示在我的应用程序上。请注意，我可以从免费主机服务器看到图像：
http://www.justedhak.comlu.com/images/uploaded_images.jpg
这个来自一个随机网站，它显示在应用程序上。
http://api.androidhive.info/json/movies/1.jpg
我的问题是我上传图片的方式有问题吗？或者可能是免费主机（000webhost）？请给我你的意见
我正在将图像上传到服务器，然后在活动中显示我可以看到url http://www.justedhak.comlu.com/images/uploaded_images.jpg但它没有显示在应用程序中。不过，我还添加了另一个图像网址及其在应用程序中的显示。
这是获取图片url的代码
protected void showList(){
try {
JSONObject jsonObj = new JSONObject(myJSON);
peoples = jsonObj.getJSONArray(TAG_RESULTS);
for(int i=0;i<peoples.length();i++){
JSONObject c = peoples.getJSONObject(i);
String id = c.getString(TAG_ID);
String url = c.getString(TAG_PATH);
Listitem.add(new Listitem(id,url));
}
GridViewAdapter adapter = new GridViewAdapter(this, R.layout.grid_item_layout, Listitem);
// gridView.setAdapter(gridAdapter);
list.setAdapter(adapter);
} catch (JSONException e) {
e.printStackTrace();
}
}
public class GetDataJSON extends AsyncTask<String, Void, String>{
@Override
protected String doInBackground(String... params) {
DefaultHttpClient httpclient = new DefaultHttpClient(new BasicHttpParams());
HttpPost httppost = new HttpPost("http://justedhak.comlu.com/get-data.php");
// Depends on your web service
httppost.setHeader("Content-type", "application/json");
InputStream inputStream = null;
String result = null;
try {
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
inputStream = entity.getContent();
// json is UTF-8 by default

StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null)
{
sb.append(line + "\n");
}
result = sb.toString();
} catch (Exception e) {
// Oops
}
finally {
try{if(inputStream != null)inputStream.close();}catch(Exception squish){}
}
return result;
}
这是上传图片
