我开发了一个应用程序，在其中显示数据Gridview。所有数据都来自本地存储。我能够正确显示每个数据并且没有问题。但是当我滚动Gridview并转到底部并返回时Top，它会改变位置。有时当我向下滚动并返回顶部时，屏幕上会出现一个空白屏幕；根本找不到数据！
所以我认为有问题getView()。我无法找出问题所在
代码getView()：
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
ViewHolder viewholder;
// LayoutInflater inflator = activit.getLayoutInflater();
if(convertView == null) {
// recycled view is null so create it.
viewholder = new ViewHolder();
convertView = inflator.inflate(R.layout.gridviewrow, null);
viewholder.imgvGridicon = (ImageView) convertView.findViewById(R.id.imgvGridicon);
viewholder.txtGridItemlabel = (TextView) convertView.findViewById(R.id.txtGridItemlabel);
convertView.setTag(viewholder);
} else {
viewholder = (ViewHolder) convertView.getTag();
}
if ((lstpinfo.get(position).appname.toString()) != null) {
viewholder.imgvGridicon.setImageDrawable((lstpinfo.get(position).icon));
viewholder.txtGridItemlabel.setText(lstpinfo.get(position).appname.toString());
}
return convertView;
}
更新:: Intitalize of inflater::
private LayoutInflater inflator;
private ArrayList<PInfo> lstpinfo = new ArrayList<PInfo>();
public GridViewAdapter(Context cntx, ArrayList<PInfo> lstpinfo) {
activit = cntx;
inflator = LayoutInflater.from(cntx);
this.lstpinfo = lstpinfo;
}
