Solution to having nested scrolling within Android. In this scenario a multiline EditText resides within a root level ScrollView. In order to have scroll momentum, the EditText itself doesn't scroll but it is wrapped within a ScrollView.

nested_scroll.xml

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
          xmlns:app="http://schemas.android.com/apk/res-auto"
          android:layout_width="match_parent"
          android:layout_height="match_parent">

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
  
  <!-- More views can go here-->
    
    <ScrollView
        android:layout_width="320dp"
        android:layout_height="284dp">
    
        <EditText
            android:id="@+id/edit_text"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="top"
            android:inputType="textCapSentences|textAutoCorrect|textMultiLine"
            android:minHeight="284dp"/>
    </ScrollView>
    
    <!-- More views can go here-->
</ScrollView>

SomeFragment.java

// When the EditText is touched, disable touches on it's ScrollView's parents.  
// Once the user lifts up their finger, enable touches on on the ScrollView's parents once again.

@OnTouch(R.id.edit_text)
boolean handleNoteFieldTouch(View v, MotionEvent event) {
    v.getParent().getParent().requestDisallowInterceptTouchEvent(true);
    switch (event.getAction() & MotionEvent.ACTION_MASK){
        case MotionEvent.ACTION_UP:
            v.getParent().getParent().requestDisallowInterceptTouchEvent(false);
            break;
    }
    return false;
}
