Showing Selected Grid Image in New Activity (Full Screen)

in main java class:

            gridView = (GridView) findViewById(R.id.gridView1);
            gridView.setAdapter(new ImageAdapter(this));
            gridView.setOnItemClickListener(new OnItemClickListener() 
                 {
      public void onItemClick(AdapterView parent,View v,int position,long id) 
                 {          
                 System.out.println("====>>"+position);
                 Intent i = new Intent(getApplicationContext(),GidImage.class);
                 // passing array index
                 i.putExtra("id", position);
                 startActivity(i);
                   }
            });

create a new java file with an image view:

            Intent i = getIntent();
               // Selected image id
            int position = i.getExtras().getInt("id");
            ImageAdapter imageAdapter = new ImageAdapter(this);
            ImageView imageView =(ImageView)
                                        findViewById(R.id.full_image_view);    
                                                                               
            imageView.setImageResource(imageAdapter.mThumbIds[position]);

in custom Adapter class:

    public class ImageAdapter extends BaseAdapter {
    private Context context;
    public Integer[] mThumbIds = {
            R.drawable.card0, R.drawable.card1,
            R.drawable.card2, R.drawable.card3,
            R.drawable.card0, R.drawable.card1,
            R.drawable.card2, R.drawable.card3,
            R.drawable.card0, R.drawable.card1,
            R.drawable.card2, R.drawable.card3
         };
    public ImageAdapter(Context context) {
        this.context = context;
    }
     @Override
    public int getCount() {
        return mThumbIds.length;
    }

    @Override
    public Object getItem(int position) {
        return mThumbIds[position];
    }

    @Override
    public long getItemId(int position) {
        return 0;
    } 
   public View getView(int position, View convertView, ViewGroup parent) {
         ImageView imageView = new ImageView(context);
         imageView.setImageResource(mThumbIds[position]);
         imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
         imageView.setLayoutParams(new GridView.LayoutParams(130, 100));
         imageView.setPadding(8, 8, 8, 8);
         return imageView;
        }
}
