@Override

@Override

@Override

封装的适配器基类。用起来挺方便哒

public class TestAdapter extends MyBaseAdapter<String> {

public TestAdapter(Context context) {
super(context);
// TODO Auto-generated constructor stub
}

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

}
