I can get data from the database but why does it still show that there is no value for the image? I have checked that the url is right to get the photo. The following things are the error showed in the logcat. Please give me some helps. Thank you.

Answer 1

You get wrong JSONObject , try this

try {
     JSONObject objId = response.getJSONObject(0);
     JSONObject objImage = response.getJSONObject(1);
     Patient patient = new Patient();
     patient.setTitle(objId.getString("id"));
     patient.setThumbnailUrl(objImage.getString("image"));

     patientList.add(patient);

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

Answer 2

Look at your response and try this

JSONObject obj = response.getJSONObject(0);
JSONObject obj1 = response.getJSONObject(1);
Patient patient = new Patient();
patient.setTitle(obj.getString("id"));  
patient.setThumbnailUrl(obj1.getString("image"));
