GridviewExampleActivity.java
public class GridviewExampleActivity extends Activity

public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
GridView gridview = (GridView) findViewById(R.id.gridview);
gridview.setAdapter(new ImageAdapter(this));
}
public class ImageAdapter extends BaseAdapter{
private Context mContext;
public ImageAdapter(Context c){
mContext = c;
}
public int getCount()
{
return mThumbIds.length;
}
public Object getItem(int position)
{
return null;
}
public long getItemId(int position)
{
return 0;
}
// create a new ImageView for each item referenced by the Adapter
public View getView(int position, View convertView, ViewGroup parent)
{
ImageView imageView;
if (convertView == null)
{
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;
}
imageView.setImageResource(R.drawable.icon);
return imageView;
