MainActivity.java`
public class MainActivity extends Activity {
static ArrayList<Actors> actorsList;
ActorAdapter adapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
actorsList = new ArrayList<Actors>();
//final ArrayList<Actors> movieList = new ArrayList<Actors>();
new JSONAsyncTask().execute("http://microblogging.wingnity.com/JSONParsingTutorial/jsonActors");
ListView listview = (ListView)findViewById(R.id.list);
adapter = new ActorAdapter(getApplicationContext(), R.layout.row, actorsList);
listview.setAdapter(adapter);
listview.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position,
long id) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), actorsList.get(position).getName(), Toast.LENGTH_LONG).show();
Actors m = actorsList.get(position);
Intent i = new Intent(MainActivity.this, SingleView.class);
i.putExtra("position", String.valueOf(position));
i.putExtra("thumb", m.getImage());
i.putExtra("name", m.getName());
i.putExtra("dob", m.getDob());
i.putExtra("height", m.getHeight());
i.putExtra("country", m.getCountry());
// View imageView = null;
//imageView.buildDrawingCache();
// Bitmap image= imageView.getDrawingCache();
// Bundle extras = new Bundle();
// extras.putParcelable("imagebitmap", image);
// i.putExtras(extras);
startActivity(i);
}
});

Try this

setContentView(R.layout.singleview);
Intent i = getIntent();
final String image1 = i.getStringExtra("thumb");
String name1 = i.getStringExtra("name");
String dob1 = i.getStringExtra("dob");

movieList_detail = MainActivity.actorsList;
name.setText(name1);

new DownloadImageTask(img).execute(image1);
back.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub

}
});
prev.setOnClickListener(new OnClickListener() {
@Override

}else
{
prev.setVisibility(View.GONE);
