我和Recyclerview一起工作。我想从其持有者处完成当前活动。当我单击项目时,我想打开新活动并完成当前活动。请帮忙 我的代码如下所示`

public class GcmNotificationHolder extends RecyclerView.ViewHolder implements View.OnClickListener {

    protected TextView gcmMessage;
    protected TextView  messageTital;
    protected  TextView messageDate;
    protected ImageButton removeMessage;
    protected Context context;
    protected  List<Notification> notificationList;
    protected  boolean isRead = true;

    public GcmNotificationHolder(View itemView, List<Notification> notificationList, Context applicationContext) {
        super(itemView);
        itemView.setOnClickListener(this);
          context = applicationContext;
        this.gcmMessage = (TextView)itemView.findViewById(R.id.gcmMessage);
        this.messageTital=(TextView)itemView.findViewById(R.id.messagTital);
        this.messageDate=(TextView)itemView.findViewById(R.id.gcmMessageDate);
        this.notificationList = notificationList;
    }



    @Override
    public void onClick(View v) {

        Intent intent = new Intent(context.getApplicationContext(), NotificationDescriptionActivity.class);
        intent.putExtra("messageDescription", notificationList.get(getAdapterPosition()).getMessage());
        intent.putExtra("messageTital", notificationList.get(getAdapterPosition()).getMessagetital());
        intent.putExtra("messageDate", notificationList.get(getAdapterPosition()).getMessagedate());
         notificationList.get(getAdapterPosition()).getId();
         notificationList.get(getAdapterPosition()).setIsRead(true);
        DaoMaster.DevOpenHelper helper = new DaoMaster.DevOpenHelper(context, "notification-db", null);
        SQLiteDatabase db = helper.getWritableDatabase();
        DaoMaster daoMaster = new DaoMaster(db);
        DaoSession daoSession = daoMaster.newSession();
        NotificationDao notificationDao = daoSession.getNotificationDao();
        notificationDao.updateInTx(notificationList);
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(intent);

}}
公共类GcmNotificationHolder扩展了RecyclerView.ViewHolder实现了View.OnClickListener{
受保护的文本视图GCM消息;
受保护的文本视图消息标题;
受保护的文本视图消息日期;
受保护的ImageButtonRemoveMessage;
受保护的语境;
受保护列表通知列表;
受保护布尔值isRead=true;
公共GcmNotificationHolder(查看项目视图、列表通知列表、上下文应用程序上下文){
超级(项目视图);
setOnClickListener(这个);
上下文=应用上下文;
this.gcmMessage=(TextView)itemView.findViewById(R.id.gcmMessage);
this.messageTital=(TextView)itemView.findViewById(R.id.messagTital);
this.messageDate=(TextView)itemView.findViewById(R.id.gcmMessageDate);
this.notificationList=notificationList;
}

当我在holder构造函数中传递Activity实例时,请解决我的问题

只需在onClick()的末尾添加下一行即可:


调用context.finish();我尝试了这种方式,但无法以这种方式调用finish(),
((Activity)context).finish();
