xamarin - 从片段关闭活动

Question

我的片段会显示交易。这是一个recyclerView。当我从片段中单击一个事务时，它将以具有相应值的形式显示，我可以删除或更新它。

如何在开始另一项活动之前通过我的片段所连接的片段关闭活动？

Answer 1

很抱歉没有更新我的问题也没有给出答案。经过试验，我只想在片段构造函数上传递活动，然后使用activity.Finish（）;当我点击回收站视图中的项目时

    private Expense_Objects expenseObject;
    private Denomination_Objects denominationObject;
    private Activity activity;

    /// <summary>
    /// Fragment for Petty Cash
    /// </summary>
    /// <param name="expenseObject">Expense Object</param>
    /// <param name="denominationObject">Denomination Object</param>
    /// <param name="activity">Activity where fragment will reside</param>
    public Fragment_PettyCash(Expense_Objects expenseObject, 
            Denomination_Objects denominationObject, Activity activity)
    {
        this.pcExpenseObject = pcExpenseObject;
        this.denominationObject = denominationObject;
        this.activity = activity;
    }

    /// <summary>
    /// Setting up recyclerView
    /// </summary>
    /// <param name="recyclerView">recyclerView</param>
    private void setUpRecyclerView(RecyclerView recyclerView)
    {
        recyclerView.SetLayoutManager(new LinearLayoutManager(recyclerView.Context));
        recyclerView.SetAdapter(new SimpleStringRecyclerViewAdapter(recyclerView.Context, 
                expenseObject.payeeList, expenseObject.totalAmountList));

        recyclerView.SetItemClickListener((rv, position, view) =>
            {
                //doing other stuffs

                Context context = view.Context;

                Intent intent = new Intent(context, typeof(UpdateDeleteExpense));

                intent.PutExtra(IntentExtras.denominationSerialized, 
                        JsonConvert.SerializeObject(denominationObject));

                intent.PutExtra(IntentExtras.pettyCashExpenseSerialized, 
                        JsonConvert.SerializeObject(expenseObject));

                context.StartActivity(intent);

                activity.Finish();
            }
        );
    }
