Android中有没有更快的替代Gallery小部件,因为Gallery太慢而且滞后,我试图使用视图持有者重用视图,但没有结果。我用经典方法
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = mInflater.inflate(R.layout.image, null);
// Creates a ViewHolder and store references to the two children views
// we want to bind data to.
holder = new ViewHolder();
holder.icon = (ImageView) convertView.findViewById(R.id.ImageView01);
convertView.setTag(holder);
} else {
// Get the ViewHolder back to get fast access to the TextView
// and the ImageView.
holder = (ViewHolder) convertView.getTag();
}
holder.icon.setImageDrawable(getPicture(items[position]));
return convertView;
}
