import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;
public class GridItemAdapter extends BaseAdapter
{
private LayoutInflater inflater;
private List<GridItem> gridItemList;

public GridItemAdapter(String[] titles, int[] images,String[] description, Context context)
{
super();
gridItemList = new ArrayList<GridItem>();
inflater = LayoutInflater.from(context);
for (int i = 0; i < images.length; i++)
{
GridItem picture = new GridItem(titles[i], images[i],description[i]);
gridItemList.add(picture);
}
}
@Override
public int getCount( )
{
if (null != gridItemList)
{
return gridItemList.size();
}
else
{
return 0;
}
}
@Override
public Object getItem( int position )
{
return gridItemList.get(position);
}
@Override
public long getItemId( int position )
{
return position;
}
@Override
public View getView( int position, View convertView, ViewGroup parent )
{
ViewHolder viewHolder;
if (convertView == null)
{
convertView = inflater.inflate(R.layout.grid_item, null);
viewHolder = new ViewHolder();
viewHolder.title = (TextView) convertView.findViewById(R.id.title);
viewHolder.image = (ImageView) convertView.findViewById(R.id.image);
viewHolder.time = (TextView) convertView.findViewById(R.id.description);
convertView.setTag(viewHolder);
} else
{
viewHolder = (ViewHolder) convertView.getTag();
}
viewHolder.title.setText(gridItemList.get(position).getTitle());
viewHolder.time.setText(gridItemList.get(position).getTime());
viewHolder.image.setImageResource(gridItemList.get(position).getImageId());
return convertView;
}

然后调用

GridItemAdapter adapter = new GridItemAdapter(titles, images,description,this);
gridView.setAdapter(adapter);
