GridView From SDCard Video

I tryed GridView. It was made from SD Card Video Clip.

I created class at extends BaseAdatpter.
Override getCount(), getItem(), getItemId(), getView().
getView() is creating ImageView from video clip.
getCount() return is SDCard Video Clip Number

public int getCount() {
 Cursor c = managedQuery(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, null, null, null,null);
 return c.getCount();
}

getItem() is no use.

public Object getItem(int arg0) {
 return null;
}

getItemId() is no use.

public long getItemId(int position) {
 return 0;
}

This is getView()..

I create Cursor and move position.

Cursor c = managedQuery(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, null, null, null,null);
c.moveToPosition(position);

check file path.

int dataIndex = c.getColumnIndex(MediaStore.Video.Media.DATA);
String path = c.getString(dataIndex);

get thumbnail bitmap.

Bitmap bmp = ThumbnailUtils.createVideoThumbnail(path,MediaStore.Video.Thumbnails.MINI_KIND );

setView.

imageView.setImageBitmap(bmp);

view set adapter extends BaseAdapter.

mGridView = (GridView)findViewById(R.id.gridView1);
mGridView.setAdapter(new ImageAdapter());
