I am trying to display my video thumbnails, but my emulator displays an empty screen. I don't know where I'm making a mistake. I am trying to show these video thumbnails in my tab host.
This is my code:
public class video extends Activity {
//set constants for MediaStore to query, and show videos
//flag for which one is used for images selection
private GridView _gallery;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mavideo);
//set GridView for gallery
_gallery = (GridView)findViewById(R.id.sdcard);
//set default as external/sdcard uri
//set gallery adapter
setGalleryAdapter();
}
private void setGalleryAdapter() {
_gallery.setAdapter(new VideoGalleryAdapter(this));
}
//
private class VideoGalleryAdapter extends BaseAdapter {
private Context mContext;
public VideoGalleryAdapter(Context c) {
mContext = c;
}
public int getCount() {
return tabview.videoList.size();
}
public Object getItem(int position) {
return null;
}
public long getItemId(int position) {
return 0;
}
public View getView(int position, View convertView, ViewGroup parent) {
ImageView imageView;
if (convertView == null) { // if it's not recycled, initialize some attributes
imageView = new ImageView(mContext);
imageView.setLayoutParams(new GridView.LayoutParams(85, 85));
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageView.setPadding(8, 8, 8, 8);
} else {
imageView = (ImageView) convertView;
}
Bitmap bitmap = BitmapFactory.decodeFile(tabview.videoList.get(position));
imageView.setImageBitmap(bitmap);
return imageView;
}
}
}
