处理按钮手势，单击和点击双击 [英] Handling Button gesture for both single and double click/tap

问题描述

在Xamarin表单中：我想要能够检测到点击/点击和双击/点击，并能够执行不同的操作。

In Xamarin Forms: I want to be able to detect both click/tap and double-click/tap, and to be able to perform different actions.

是，当点击按钮时，我想执行 actionA ，当按钮被双击时，我想执行 actionB ，而只有 actionB 。

That is, when the button is clicked I want to perform actionA, and when the button is double-clicked I want to perform actionB, and only actionB.

做（对Amit Patil的赞许）：

Here's what I ended up doing (kudos to Amit Patil):

    private static int clickCount;
    private static object _sender;

    private void Button_Clicked(object sender, EventArgs e)
    {
        if (clickCount < 1)
        {
            TimeSpan tt = new TimeSpan(0, 0, 0, 0, 250);
            _sender = sender;
            Device.StartTimer(tt, ClickHandle);
        }
        clickCount++;
    }

    bool ClickHandle()
    {
        if (clickCount > 1)
        {
            Minus1(_sender);
        }
        else
        {
            Plus1(_sender);
        }
        clickCount = 0;
        _sender = null;
        return false;
    }
