how to fire an event when someone clicks anywhere on the screen in an android app?

Question

how can I catch the event when click occurs somewhere on the app screen? It doesn\'t matter if there is a button or something else. I just need to apply an onClick()

Answer 1

You should just override Activity's dispatchTouchEvent(ev: MotionEvent) method

Look at this example in Kotlin. This approach will not affect any onClickListenters in your app

/**
 * On each touch event:
 * Check is [snackbar] present and displayed
 * and dismiss it if user touched anywhere outside it's bounds
 */
override fun dispatchTouchEvent(ev: MotionEvent): Boolean {
    // dismiss shown snackbar if user tapped anywhere outside snackbar
    snackbar?.takeIf { it.isShown }?.run {
        val touchPoint = Point(Math.round(ev.rawX), Math.round(ev.rawY))
        if (!isPointInsideViewBounds(view, touchPoint)) {
            dismiss()
            snackbar = null // set snackbar to null to prevent this block being executed twice
        }
    }

    // call super
    return super.dispatchTouchEvent(ev)
}
