How to disable BottomSheetDialogFragment dragging

Question

How to disable BottomSheetDialogFragment dragging by finger?

I saw similar questions, but they\'re all about BottomSheet not BottomSheetD

Answer 1

There is simpler way of achieving the same after material design 1.2.0 was released.

https://developer.android.com/reference/com/google/android/material/bottomsheet/BottomSheetBehavior#setdraggable

When calling from BottomSheetDialogFragment:

    override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
        val bottomSheetDialog = super.onCreateDialog(savedInstanceState) as BottomSheetDialog
        bottomSheetDialog.setOnShowListener {
            val bottomSheet = bottomSheetDialog
                .findViewById(com.google.android.material.R.id.design_bottom_sheet)

            if (bottomSheet != null) {
                val behavior: BottomSheetBehavior<*> = BottomSheetBehavior.from(bottomSheet)
                behavior.isDraggable = false
            }
        }
        return bottomSheetDialog
    }

Or with styling:

And then in onCreate of your dialog fragment:

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setStyle(DialogFragment.STYLE_NORMAL, R.style.SomeStyle)
    }
