i'm working on an app that loads images of popular movies using TheMovieDB API and display them in a Grid view (and other things as well, but that's not important at this moment) i'm facing these errors and i need help to solve them..here is a snapshot for the errors
enter image description here here is MovieAdapter.java
package com.example.android.movies;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import com.squareup.picasso.Picasso;
import java.util.ArrayList;
/**

*/
public class MovieAdapter extends BaseAdapter{
ArrayList<Movies> MovieList;
Context mContext;
public MovieAdapter(Context context,ArrayList<Movies> movieArrayList) {
this.mContext=context;
this.MovieList=movieArrayList;
}
@Override
public int getCount() {
return MovieList == null ? 0 : MovieList.size();
}
@Override
public Object getItem(int position) {
return MovieList.get(position);
}
@Override
public long getItemId(int id) {return MovieList.get(id).getMposter_id(); }
@Override
public View getView(int position, View ConvertedView, ViewGroup viewGroup) {
View view=ConvertedView;
if (view==null)
{
LayoutInflater inflater=(LayoutInflater)
mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view=inflater.inflate(R.layout.grid_item,null);
}
ImageView ivMovieName= (ImageView) view.findViewById(R.id.image_view);
Picasso.with(mContext)
.load("http://image.tmdb.org/t/p/w185"+MovieList.get(position).getMposter_path()).into(ivMovieName);
return view;
}
}
