我有一个扩展ArrayAdapter的内部类,以自定义ListView。我想将此内部类分解为一个单独的文件,以便其他类可以使用它,但在getLayoutInflater()上遇到了一些麻烦。
基本上,即使扩展了ArrayAdapter,我的getView()方法也不知道getLayoutInflater()是什么。任何人都知道如何使它正常工作吗?
谢谢!
public class myDynAdap extends ArrayAdapter<String>
{
String [] list;
public myDynAdap (Context context, int textViewResourceId, String [] objects)
{
super (context, textViewResourceId, objects);
mCtx = context;
list = objects;
}
@Override
public View getView (int position, View convertView, ViewGroup parent)
{
View row = convertView;
if (row == null)
{
LayoutInflater inflater = getLayoutInflater (); // <--- "The method getLayoutInflater() is undefined for the type myDynAdap"
row = inflater.inflate (R.layout.main_listitem, parent, false);
}
TextView tv1 = (TextView) row.findViewById (R.id.tv_item);
tv1.setBackgroundColor (Color.BLUE);
// change background of 0th list element only
if (position == 0)
tv1.setBackgroundColor (Color.CYAN);
return row;
}
}
最佳答案
在传入的上下文中调用getLayoutInflater()
怎么样?
LayoutInflater inflater = ((Activity)context).getLayoutInflater();
