Android toasts showing time

Question

In my application for Android the user has to tap a button and every time the button is tapped a toast appears saying "you have tapped n times", but if the user taps quickly several times the toasts are too slow and they appear one by one.

public void onClick(View v)
{
    n++;
    Toast.makeText(MainActivity.this, "You have tapped "+n+" times", Toast.LENGTH_SHORT).show();
}

Is there a way to "delete" all the old toasts in order to let appear only the last one?

Keep a reference to your Toast object and call .cancel() to it. [Toast.cancel()](https://developer.android.com/reference/android/widget/Toast.html#cancel()) — ElegyD, Feb 09 '17 at 16:05

Instead of making a new Toast everytime, keep your instance and update the text

mToast.setText("newMessage");

Didn't know you could do that. And I thought I had the 'Toast topic' pretty much exhausted. – fweigl Feb 09 '17 at 19:44

Keep a reference to the toast and dismiss it.

Toast toast; 

public void onClick(View v)
{
    if (toast != null) toast.dismiss()
    n++;
    toast =  Toast.makeText(MainActivity.this, "You have tapped "+n+" times", Toast.LENGTH_SHORT);
    toast.show()
}
