Scrollview not scrolling in Android bottomsheet

Question

I tried the new BottomSheet in Android support. Inside the BottomSheet I have put a TextView and a ScrollView. The BottomSheetshowing just fine, the only problem I found is that the ScrollView in the BottomSheet is not scrolling. Every time I try to scroll, either the layout in main activity that scroll or the BottomSheet changing state from collapse to expand.

This is snippet of my Activity Class code:

private BottomSheetBehavior behavior; View bottomSheet;  @Override protected void onCreate(Bundle savedInstanceState) {     super.onCreate(savedInstanceState);     setContentView(R.layout.main);      setTextViewOnClickListener(this, findViewById(R.id.parentLayout));      CoordinatorLayout coordinatorLayout = (CoordinatorLayout) findViewById(R.id.main_content);      // The View with the BottomSheetBehavior     bottomSheet = coordinatorLayout.findViewById(R.id.bottom_sheet);     behavior = BottomSheetBehavior.from(bottomSheet);     behavior.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {         @Override         public void onStateChanged(@NonNull View bottomSheet, int newState) {             // React to state change          }           @Override         public void onSlide(@NonNull View bottomSheet, float slideOffset) {             // React to dragging events         }     });  @Override public void onClick(View v) {     switch (v.getId()) {         case R.id.tv1:             setTextViewHeader("Header1");             setTextViewContent("Long_Text_1");              break;          case R.id.tv2:             setTextViewHeader("Header2");             setTextViewContent("Long_Text_2");              break;          case R.id.tv3:             setTextViewHeader("Header3");             setTextViewContent("Long_Text_3");              break;          default:             break;     }      behavior.setPeekHeight(100);     behavior.setState(BottomSheetBehavior.STATE_COLLAPSED);     behavior.setHideable(true);      bottomSheet.requestLayout(); } 

This is my Layout XML:

Hope you figured out this by now, but change View bottomSheet to NestedScrollView bottomSheet.
