如何解决如何将点击方法分配给外部键盘上的按键安卓系统

嗨，我有一些 Clik 方法，如果按下外部键，它们也需要执行，即。 F1、F2、F3...如何将按下的键分配给这些方法？可能吗？

       // UnfinishedissuedGoodsView layout ---> button ---------> goodsIssued
        Button buttonIssued = FindViewById<Button>(Resource.Id.goodsIssued);
        buttonIssued.Click += ButtonIssued_Click;
        // btnPrint-----------PrintingMenu();
        Button buttonPrint = FindViewById<Button>(Resource.Id.btnPrint);
        buttonPrint.Click += ButtonPrint_Click;
        // btnInventory-------InventoryMenu();
        Button btnInventory = FindViewById<Button>(Resource.Id.btnInventory);
        btnInventory.Click += BtnInventory_Click;
        // btCheckStock-------CheckStock();
        Button btnCheckStock = FindViewById<Button>(Resource.Id.btCheckStock);
        Keycode.F9 =>  btnCheckStock.Click += BtnCheckStock_Click;
        // goodsPackaging-----PackagingEnteredPositionsView();
        Button btnPackaging = FindViewById<Button>(Resource.Id.goodsPackaging);
        btnPackaging.Click += BtnPackaging_Click;
