我有自定义适配器列表视图PROGRAMM工作没有错误回报,但列表视图是空如何使用自定义适配器填充ListView?列表视图空(
我的适配器看起来象是:。
public class CustomAdapter extends BaseAdapter implements Filterable {
private ArrayList<OItem> _data;
Context _c;
public CustomAdapter(ArrayList<OItem> data, Context c) {
_data = data;
_c = c;
}
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null)
{
LayoutInflater vi = (LayoutInflater)_c.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.item, null);
}
OItem oItem = _data.get(position);
TextView tvId = (TextView)v.findViewById(R.id.id);
TextView tvName = (TextView)v.findViewById(R.id.name);
TextView tvBatch = (TextView)v.findViewById(R.id.batch);
tvId.setText(oItem.getId());
tvName.setText(oItem.getName());
tvBatch.setText(oItem.getBatch());
return v;
}
}
在活动时间:
ArrayList<OItem> arrItems = new ArrayList<OItem>();
....
here I fill arrItens with the data
....
ListView lvSimple = (ListView) findViewById(R.id.lvContent);
lvSimple.setAdapter(new CustomAdapter(arrItems, this));
可能是什么问题? 也许应该在getView方法中加入适配器?
谢谢
尝试_data = data.clone添加这个(); – 2013-04-06 19:26:42
你有没有使用ArrayAdapter而不是BaseAdapter的具体原因? – FoamyGuy 2013-04-06 19:28:32
