Question

android fragment有listview，每次进入这个fragment，listview的item都会重复加载。如何解决？

Adapter 部分代码
public class ListViewItemAdapter extends BaseAdapter {

@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
try {

ViewHolder holder = null;

if (convertView == null) {

holder = new ViewHolder();

convertView = inflater.inflate(R.layout.layout_listview_item,
null);
holder.item_icon = (ImageView) convertView
.findViewById(R.id.item_icon);// 设置每个条目的图标
holder.item_text = (TextView) convertView
.findViewById(R.id.item_text); // 设置条目的文字说明
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}

if (0 == position) {
holder.item_icon
.setBackgroundResource(android.R.drawable.ic_menu_agenda);
} else if (1 == position) {
holder.item_icon
.setBackgroundResource(android.R.drawable.ic_menu_share);
} else if (2 == position) {
holder.item_icon
.setBackgroundResource(android.R.drawable.ic_menu_manage);
} else if (3 == position) {
holder.item_icon
.setBackgroundResource(android.R.drawable.ic_menu_edit);
} else {
holder.item_icon
.setBackgroundResource(android.R.drawable.ic_menu_close_clear_cancel);
}
holder.item_text.setText(more_list.get(position));

return convertView;
} catch (Exception e) {
Log.e(TAG, "getView error", e);
return null;
}
}
}
