Android - Intercept and pass on all touch events

Question

I have an overlay ViewGroup that is the size of the screen which I want to use to show an effect when the user interacts with the app, but still passes the onTouch event to any

Answer 1

I tried all of the solutions in the above answers however still had issues receiving all touch events while still allowing children views to consume the events. In my scenario I would like to listen in on events that a child views would consume. I could not receive follow up events after a overlapping child view started consuming events.

I finally found a solution that works. Using the RxBinding library you can observe all touch events including events that are consumed by overlapping children views.

Kotlin Code snippet

RxView.touches(view)
    .observeOn(AndroidSchedulers.mainThread())
    .subscribe(

        object  : Observer {
            override fun onCompleted() {
            }

            override fun onNext(t: MotionEvent?) {
                Log.d("motion event onNext $t")
            }

            override fun onError(e: Throwable?) {
            }
        }
    )
