我是新来的Android和我使用的MySQL数据库，在那里我链接连接这是工作的罚款php文件，但我的code未显示任何东西它只是显示背景色而不是黑色显示的数据数据库

i am new to android and i am using mysql database where i am linking php file for connection which is working fine but my code is not displaying anything it is only showing background color black instead of displaying the data from the database

public class HomeFragment extends Fragment {



GridView gv;
@SuppressLint("NewApi")
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.home, container, false);
    StrictMode.enableDefaults();
    gv = (GridView) rootView.findViewById(R.id.gridView_home);
    getData();
    return rootView;
}
public void getData(){
    String result = "";
    InputStream isr = null;
    try{
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost("http://192.168.1.2/Android/App/getcu.php"); //YOUR PHP SCRIPT ADDRESS 
        HttpResponse response = httpclient.execute(httppost);
        HttpEntity entity = response.getEntity();
        isr = entity.getContent();
}
catch(Exception e){
        Log.e("log_tag", "Error in http connection "+e.toString());
        gv.setFilterText("Couldnt connect to database "+ e.getMessage()); //not printing anything
}
//convert response to string
try{
        BufferedReader reader = new BufferedReader(new InputStreamReader(isr,"iso-8859-1"),8);
        StringBuilder sb = new StringBuilder();
        String line = null;
        while ((line = reader.readLine()) != null) {
                sb.append(line + "n");
        }
        isr.close();

        result=sb.toString();
}
catch(Exception e){
        Log.e("log_tag", "Error  converting result "+e.toString());
}


try {


   String s = "";
   JSONArray jArray = new JSONArray(result);

   for(int i=0; i<jArray.length();i++){
       JSONObject json = jArray.getJSONObject(i);
       s = s + 
               "Name : "+json.getString("FirstName")+" "+json.getString("LastName")+"n"+
               "Age : "+json.getInt("Age")+"n"+
               "Mobile Using : "+json.getString("Mobile")+"nn";//+
               "Artist:"+json.put("Images",true ); // not printing anything 
   }

   gv.setFilterText(s); // not printing showing empty
} catch (Exception e) {



// TODO: handle exception
   Log.e("log_tag", "Error Parsing Data "+e.toString()); }

}  }

多了一个错误，而从文件夹中的Android /图片/ JSON此搜索检索图像不打印部署到数据库中的特定图像

one more error while retrieving images from folder Android/pictures/image1 json is not printing the particular image deployed into database

"Artist:"+json.put("Images",true );

是上面的语句正确检索使用JSON的图像或我必须纠正

is the above statement correct to retrieve the images using json or i have to correct it

请帮我纠正上述方案感谢您的宝贵时间我不能够理解为什么它没有打印任何东西，但它工作时，我把它扩展到活动如何使用它的片断

please help me to correct the above program thanks for your valuable time i am not able to understand why it is not printing anything but it is working when i extend it to activity how to use it in fragment
