Android BottomSheetDialogFragment does not expand completely

Using this code in onCreateView.

getDialog().setOnShowListener(new DialogInterface.OnShowListener() {
        @Override
        public void onShow(DialogInterface dialog) {
            BottomSheetDialog d = (BottomSheetDialog) dialog;
            FrameLayout bottomSheet = (FrameLayout) d.findViewById(R.id.design_bottom_sheet);
            CoordinatorLayout coordinatorLayout = (CoordinatorLayout) bottomSheet.getParent();
            BottomSheetBehavior bottomSheetBehavior = BottomSheetBehavior.from(bottomSheet);
            bottomSheetBehavior.setPeekHeight(bottomSheet.getHeight());
            coordinatorLayout.getParent().requestLayout();
        }
    });

I've found another solution. Maybe for future readers it can be useful.

@Override
public void setupDialog(Dialog dialog, int style) {
    super.setupDialog(dialog, style);
    final View root = View.inflate(getContext(), R.layout.fragment_bottom_sheet_choose_time, null);
    dialog.setContentView(root);
    initView(root);

    CoordinatorLayout.LayoutParams params = (CoordinatorLayout.LayoutParams) ((View) root.getParent()).getLayoutParams();
    CoordinatorLayout.Behavior behavior = params.getBehavior();

    if (behavior != null && behavior instanceof BottomSheetBehavior) {
        mBottomSheetBehavior = (BottomSheetBehavior) behavior;
        mBottomSheetBehavior.setBottomSheetCallback(mBottomSheetBehaviorCallback);

        root.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
            @Override
            public void onGlobalLayout() {
                root.getViewTreeObserver().removeGlobalOnLayoutListener(this);
                int height = root.getMeasuredHeight();
                mBottomSheetBehavior.setPeekHeight(height);
            }
        });
    }
}

As @Anthonyeef mentioned, here ViewTreeObserver is aimed to get the exact measure height after the view is really measured and the GlobalOnLayoutListener is removed for better performance.

But please, before using in production, test this solution on different devices and screens, because if your content in bottom sheet is higher than your screen it can produce some strange swipe behavior.
