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;

}

private Integer[] mThumbIds = {

R.drawable.icon, R.drawable.icon,

R.drawable.icon, R.drawable.icon,

R.drawable.icon, R.drawable.icon,

R.drawable.icon, R.drawable.icon,

R.drawable.icon, R.drawable.icon};

}

}
