Question

实际上我是从一个片段转到另一个片段，它将异常上下文显示为null。有人有解决方案吗？

dashboard_newrequest_list.setAdapter(new OngingmechanicAdapter(getActivity(),
                                                    Newrequest_Makes_Name,Newrequest_Model_Name,Newrequest_Servicenames,Newrequest_Pknames,Newrequest_Location,Newrequest_order_number,Newrequest_Bookid,Newrequest_Imgpath));

OngingmechanicAdapter

Context con;
 psapplication appication;
public OngingmechanicAdapter(Context con,
                             ArrayList<String> Newrequest_Makes_Name,  ArrayList<String> Newrequest_Model_Name,
                             ArrayList<String> Newrequest_Servicenames, ArrayList<String> Newrequest_Pknames, ArrayList<String> Newrequest_Location,
                             ArrayList<String> Newrequest_Bookid,
                             ArrayList<String> Newrequest_order_number,
                             ArrayList<String> Newrequest_Imgpath
                           ) {


    appication=new psapplication(con);

    this.Newrequest_Makes_Name  = Newrequest_Makes_Name;
