画廊小部件的替代品
Android 中是否有比 Gallery 小部件更快的替代方案,因为 Gallery 太慢且滞后,我尝试使用视图持有者来重用视图,但没有结果。我用了经典的方法
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;
}
Is there any faster alternative to Gallery widget in Android, because Gallery is so slow and lagging, i tryed to use view holder to reuse views, but without result. i used classic method
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;
}
