您好,我在Gridview中遇到问题。并且主要是在三星手机中。有时候图标在滚动时是不可见的,或者在屏幕上留下大量空间。这一切都发生在滚动菜单时。请检查截图。 gridviewadapter.java
public class GridviewAdapter extends ArrayAdapter<HomepageGeSe>
{
Context context;
int layoutResourceId;
ArrayList<HomepageGeSe> data = null;
RecordHolder holder = null;
public GridviewAdapter(Context context, int layoutResourceId, ArrayList<HomepageGeSe> data) {
super(context, layoutResourceId, data);
this.layoutResourceId = layoutResourceId;
this.context = context;
this.data = data;
}
static class RecordHolder {
TextView txtTitle;
ImageView imageItem;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = mInflater.inflate(layoutResourceId, parent, false);
holder = new RecordHolder();
holder.txtTitle = (TextView) convertView.findViewById(R.id.item_text);
holder.imageItem = (ImageView) convertView.findViewById(R.id.item_image);
convertView.setTag(holder);
} else {
holder = (RecordHolder) convertView.getTag();
}
HomepageGeSe list = data.get(position);
holder.txtTitle.setText(list.getName());
if(list.getDrawableId() != 0)
{
holder.txtTitle.setText(list.getName());
Picasso.with(context)
.load(list.getDrawableId())
.fit ()
.error(R.drawable.imagenotavailable)
.into(holder.imageItem);
}
return convertView;
}
}
