private void getDataAndPopulate()
{
Cursor cursor = getEvents("bcuk_book");
while (cursor.moveToNext())
{
String temp_id = cursor.getString(0);
final String temp_name = cursor.getString(1);
String temp_author=cursor.getString(2);
String temp_desc=cursor.getString(3);
byte[] temp_image = cursor.getBlob(4);
String temp_rating = cursor.getString(5);

String temp_update=cursor.getString(7);
mapId.add(temp_id);
mapName.add(temp_name);

String[] captionArray = (String[]) mapName.toArray(new String[mapName.size()]);
itemsAdapter = new ItemsAdapter(
Bookicon.this, R.layout.item,captionArray);
gridView=(GridView)findViewById(R.id.list);
gridView.setAdapter(itemsAdapter);
gridView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v, int position, long id)
{
Intent i = new Intent(getApplicationContext(), DetailsActivity.class);
i.putExtra("id", position);
startActivity(i);
}
});
}
}
और मेरे आइटम एडाप्टर वर्ग है ::
private class ItemsAdapter extends BaseAdapter implements ListAdapter

ImageView img = null;
if (view == null)

view = vi.inflate(R.layout.item, null);
}
img = (ImageView) view.findViewById(R.id.image);
Log.i("iiiiii","iiiii");
cap = (TextView) view.findViewById(R.id.caption);
System.err.println("Position of the book is "+mapName.get(POSITION));
bookTitle=mapName.get(POSITION);
System.err.println("title of the book is "+bookTitle);
cap.setText(mapName.get(POSITION));
img.setImageBitmap(BitmapFactory.decodeByteArray(map.get(POSITION), 0, map.get(POSITION).length));
return view;
}
public int getCount()

return items.length;
}
public Object getItem(int position)
