我正在尝试我在网上看到的教程，该应用程序从服务器获取并显示 JSONfeed，这部分工作正常，我正在尝试在自定义列表视图中显示此提要，但是当我尝试这样做时，我收到“尝试完成输入事件，但输入事件接收器已被处理” logcat 中的错误，应用程序中没有任何反应，我有一个适配器类：
public class UserAdapter extends ArrayAdapter<UserData>{
private Context context;
private List<UserData> users_list;
public UserAdapter(Context context, int resource,List<UserData> objects) {
super(context, resource);
this.context= context;
this.users_list= objects;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater= (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View customview= inflater.inflate(R.layout.item_user, parent, false);
UserData userData= users_list.get(position);
TextView tv = (TextView) customview.findViewById(R.id.textview1);
tv.setText(userData.getName());
return customview;
}
}

In your Public UserAdapter function, your super is not passing in the Objects.
在您的 Public UserAdapter 函数中，您的 super 没有传入对象。
It should be:
它应该是：
public UserAdapter(Context context, int resource,List<UserData> objects)
{
super(context, resource, objects);
this.context= context;
this.users_list= objects;
}
and not:
并不是：
public UserAdapter(Context context, int resource,List<UserData> objects)
{
super(context, resource);
this.context= context;
this.users_list= objects;
}
