Input cancellation on Android
Users should be able to cancel accidental interaction. For example, when users accidentally touches the wrong button, they should be able to undo this and avoid performing an action. Accidental interaction is more common for people with various disabilities.
On Android, you should avoid using the ACTION_DOWN
event of OnTouchListener
, because users will not be able to cancel their interaction. Actions should only be activated through an ACTION_UP
event. Use an OnClickListener
instead, because it has built-in support for cancellation.
webView.setOnTouchListener { _, event ->
if (event == MotionEvent.ACTION_DOWN) {
// Use OnClickListener instead
}
}
