How to Allow outside touch for BottomSheetDialog?

I am working on BottomSheetDialogFragment my requirement is to create Bottom menu, Where if I click outside fragment area it should not cancel the Dialog and should persist.

ISSUE: And Event outside the Fragment should propagate to the lower fragment view/fragment.

I have already tried below(doesn't work for BottomDialogFragment): Allow outside touch for DialogFragment

To stop the dialog cancel i tried Below(i call setCancelable(boolean) in onStart() of BottomDialogFragment):

@Override
    public void setCancelable(boolean cancelable) {
        super.setCancelable(cancelable);

        BottomSheetDialog dialog = (BottomSheetDialog) getDialog();
        dialog.setCanceledOnTouchOutside(cancelable);

        View bottomSheetView = dialog.getWindow().getDecorView().findViewById(R.id.design_bottom_sheet);
        BottomSheetBehavior.from(bottomSheetView).setHideable(cancelable);
    }

EDIT: Found it the hard way there is no other go then using Coordinate layout.The best solution for BottomSheetDialog is here

This Solution solve's the issue but bring's in one more issue. i.e all the actionMode event's are not navigated while all other app event's are.
And this is my best solution to the problem

Solution

you should use android.support.design.widget.BottomSheetBehavior.

but if you want to have a bottomSheet in other class I suggest you use a Fragment and in this fragment open your bottomSheet

open your fragment in this way.

And in your fragment, open your bottomSheet in the following code:

in onInitViews

var mBottomSheetBehavior = BottomSheetBehavior.from(bottomSheetCoordinatorLayout)
mBottomSheetBehavior!!.state = BottomSheetBehavior.STATE_HIDDEN

mBottomSheetBehavior!!.setBottomSheetCallback(object : BottomSheetBehavior.BottomSheetCallback() {
     override fun onStateChanged(bottomSheet: View, newState: Int) {
          when (newState) {
             BottomSheetBehavior.STATE_HIDDEN -> {
                  fragmentManager?.popBackStack()
             }
             //BottomSheetBehavior.STATE_COLLAPSED -> "Collapsed"
             //BottomSheetBehavior.STATE_DRAGGING -> "Dragging..."
             //BottomSheetBehavior.STATE_EXPANDED -> "Expanded"
             //BottomSheetBehavior.STATE_SETTLING -> "Settling..."
           }
      }

      override fun onSlide(bottomSheet: View, slideOffset: Float) {
          //text_view_state!!.text = "Sliding..."
      }
})

And your layout should be like this:

<android.support.design.widget.CoordinatorLayout 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"
    android:layoutDirection="ltr">

    <android.support.design.widget.CoordinatorLayout
        android:id="@+id/bottomSheetCoordinatorLayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:behavior_hideable="true"
        app:behavior_peekHeight="55dp"
        app:layout_behavior="@string/bottom_sheet_behavior">

        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@drawable/top_radius_primary_color"
            android:paddingStart="@dimen/material_size_32"
            android:paddingEnd="@dimen/material_size_32">

        </RelativeLayout>
    </android.support.design.widget.CoordinatorLayout>
</android.support.design.widget.CoordinatorLayout>

I hope it helps you
