How to load image in Viewholder of MovieAdapter?

Main Code

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.movie);
lv =(ListView)findViewById(R.id.lstMovieData);
moviename.clear();


// tv = (TextView) findViewById(R.id.tv);


Bundle b = getIntent().getExtras();
try {
Title = b.getString("MOVIE");
t = replace(Title);

} catch (Exception e) {

}

String API = "https://api.cinemalytics.com/v1/movie/title/?value=" + t + "&auth_token=<token>";
Toast.makeText(getApplicationContext(), Title, Toast.LENGTH_LONG).show();
OkHttpClient Client = new OkHttpClient();
Request request = new Request.Builder()
.url(API).build();
Call call = Client.newCall(request);
call.enqueue(new Callback() {
@Override
public void onFailure(Request request, IOException e) {

}

@Override
public void onResponse(final Response response) throws IOException {
try {


String json = response.body().string();
Log.v(TAG, json);
if (response.isSuccessful()) {

getDATA(json);

runOnUiThread(new Runnable() {
@Override
public void run() {


mAdapter = new MovieAdapter(getApplicationContext(),moviename);
lv.setAdapter(mAdapter);
}

});

} else {

}
} catch (Exception e) {

}


}
});



}



public String replace(String str) {
return str.replaceAll(" ", "%20");
}

private void getDATA(String json) throws JSONException {
try {

moviename = new ArrayList<>();
Currentmovie c = new Currentmovie();
String story = "About The Story";

JSONArray values = new JSONArray(json);
for(int i = 0; i < values.length(); i++) {
JSONObject jsonObject = values.getJSONObject(i);

String movieTitle = jsonObject.getString("Title");
String disc = jsonObject.getString("Description");
Log.e(TAG,"GIRISH"+movieTitle);
c= new Currentmovie();
c.setTitle("Movie Name::"+movieTitle);
c.setDesc(story+"::\n"+disc);
if(jsonObject.getString("Description")==null)
{

c.setDesc(story+"::Not Available");
}
moviename.add(c);

}
}
catch (Exception e)
{
System.out.println("Error in Result as " + e.toString());
}

}


2.MovieAdapter.java

public class MovieAdapter extends BaseAdapter {

Context context;
private List<Currentmovie> movieData;
private static LayoutInflater inflater = null;


public MovieAdapter( Context context,List<Currentmovie> movieData)
{
this.context = context;
this.movieData = movieData;
inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}

@Override
public int getCount() {
return movieData.size();
}

@Override
public Object getItem(int position) {
return movieData.get(position);
}

@Override
public long getItemId(int position) {
return position;
}


public static class ViewHolder{
public TextView movieTitle,movieDesc;
public ImageView movieImage;


}

public View getView(int position, View convertView, ViewGroup parent)
{


View vi = convertView;
ViewHolder holder;

if(convertView==null){
vi = inflater.inflate(R.layout.row, null);

holder = new ViewHolder();
holder.movieTitle = (TextView) vi.findViewById(R.id.tv);
holder.movieDesc=(TextView)vi.findViewById(R.id.tv1);


vi.setTag( holder );
}
else
holder=(ViewHolder)vi.getTag();



holder.movieTitle.setText(movieData.get(position).getTitle());
holder.movieDesc.setText(movieData.get(position).getDesc());



return vi;
}

}



//i can successfully show all data except image

//image link comes with "posterpath" key

//tell me how to load image in viewholder of MovieAdapter

//currentmovie is just a getter and setter class


3.Currentmovie.java

public class Currentmovie {

private String mTitle;
private String Description;


public String getDesc() {
return Description;
}

public void setDesc(String desc) {
Description = desc;
}
public String getTitle() {
return mTitle;
}

public void setTitle(String title) {
mTitle = title;
}
}

Answer

I am using this library and loading images by

first creating the Display options object by

    DisplayImageOptions builder = new DisplayImageOptions.Builder()
                                .cacheOnDisk(true)
                                .showImageOnLoading(R.drawable.empty_photo)        
                                .showImageForEmptyUri(R.drawable.empty_photo)
                                .build();

Then initialze the image loader by

  ImageLoader imageLoader = ImageLoader.getInstance();

and load images by

 imageLoader.displayImage(url, 
                          holder.movieImage, builder);

Hope this helps.. also add this to you gradle

  compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.5'

Refer this first

EDIT: Add this to onCreate() of activity

    ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(this)
        ...
        .build();
    ImageLoader.getInstance().init(config);

or this

   ImageLoader.getInstance().init(ImageLoaderConfiguration.createDefault(Activity.this‌​));
