Prevent Rapid Clicks On a Button in Xamarin Forms

Things developers face while programming: We have seen rapid clicking on a button invoking the same event or the same process many times. Here we will find a way to control the rapid click error of a button.

We can write a class named SingleClick, in which we will write a method, Click with Object and EventArgs, as arguments to do the magic. Refer to the below code snippet for more. 



public class SingleClick  
{  
    bool hasClicked;  
    #region Button Click  
    Action < object, EventArgs > _setClick;  
    public SingleClick(Action < object, EventArgs > setClick)  
    {  
        _setClick = setClick;  
    }#endregion Button Click  
  
    public void Click(object s, EventArgs e)   
    {  
        if (!hasClicked)  
        {  
            _setClick(s, e);  
            hasClicked = true;  
        }  
        Reset();  
    }  
    async void Reset()   
    {  
        await Task.Delay(800);  
        await Task.Run(new Action(() => hasClicked = false));  
    }  

}  



Usage :

var button = new Button();  

button.Clicked += new SingleClick(Button_Clicked).Click;
