title: Android Kotlin child onClick blocks parent OnTouch
body: <p>I have this layout hierarchy:</p>
  
  <pre><code>&lt;LinearLayout
      xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto"
      android:id="@+id/parent"
      android:layout_width="match_parent"
      android:layout_height="match_parent"&gt;
  
      &lt;com.xxxxxx.Widget
          android:id="@+id/widget1"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"/&gt;
  
      &lt;com.xxxxxx.Widget
          android:id="@+id/widget2"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"/&gt;
      &lt;/LinearLayout&gt;
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>I have touch Events for the Parent LinearLayout like this:</p>
  
  <pre><code>parent.setOnTouchListener(myCustomTouchParent)
  
      class MyCustomTouchParent(ctx: Context): View.OnTouchListener {
  
          private var isScrollingDown = false
          private var isScrollingUp = false
          private val myGestureDetected = GestureDetector(ctx, MyGestureListener())
  
          var onRecyclerViewMovingDown: (() -&gt; Unit)? = null
  
          override fun onTouch(p0: View?, e: MotionEvent): Boolean {
              myGestureDetected.onTouchEvent(e)
  
              when(e.action){
                  MotionEvent.ACTION_UP -&gt; {
                      if (isScrollingDown) {
                          onRecyclerViewMovingDown?.invoke()
                      }
                  }
  
                  MotionEvent.ACTION_DOWN -&gt; {
                      Log.i("TAg", "Action Down")
                      isScrollingDown = false
                      isScrollingUp = false
  
                  }
              }
              return true
          }
  
          inner class MyGestureListener: GestureDetector.SimpleOnGestureListener() {
              override fun onScroll(e1: MotionEvent, e2: MotionEvent, distanceX: Float, distanceY: Float): Boolean {
                  if(e2.y - e1.y &gt; 0){
                      isScrollingUp = true
                  } else if(e2.y - e1.y &lt; 0){
                      isScrollingDown = true
                  }
                  return super.onScroll(e1, e2, distanceX, distanceY)
              }
  
  
          }
      }
  </code></pre>
  
  <p>Basically, this will detect a 'Scroll Up' event on the parent, and will perform some animations. The problem is, as soon as I set a click listener for widget1 and widget2, the touch event of the parent is no longer working. Is there any workaround for this?</p>
