Gridview - Click image to view image in Viewpager

First of all you have to implement ImageAdapter class' method getItem(int position) to return the item at "position" in MyArr.Next, in click listener, you can do something like

HashMap<String, Object> selected = (HashMap<String, Object>) gridView.getItemAtPosition(position);

With selected you have your bitmap.

See this class you can find

GridView gridView = (GridView) findViewById(R.id.gridview);        gridView.setAdapter(new ImageAdapter());        gridView.setOnItemClickListener(new OnItemClickListener() {            @Override            public void onItemClick(AdapterView<?> parent, View view,                    int position, long id) {                startImageGalleryActivity(position);            }        });

Here you will get same output what you wants.
