Bottomsheetdialogfragment Doesn't Show Full Height In Landscape Mode

I am using BottomSheetDialogFragment in my activity, the dialog shows full height in portrait mode but doesn't when I switch to landscape mode. MainActivity.java public class M

Solution 1:

the solution for this issue is.

@OverridepublicvoidonViewCreated(View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    view.getViewTreeObserver().addOnGlobalLayoutListener(newViewTreeObserver.OnGlobalLayoutListener() {
        @OverridepublicvoidonGlobalLayout() {
            if (Build.VERSION.SDK_INT < 16) {
                view.getViewTreeObserver().removeGlobalOnLayoutListener(this);
            } else {
                view.getViewTreeObserver().removeOnGlobalLayoutListener(this);
            }
            BottomSheetDialogdialog= (BottomSheetDialog) getDialog();
            FrameLayoutbottomSheet= (FrameLayout)
            dialog.findViewById(android.support.design.R.id.design_bottom_sheet);
            BottomSheetBehaviorbehavior= BottomSheetBehavior.from(bottomSheet);
            behavior.setState(BottomSheetBehavior.STATE_EXPANDED);
            behavior.setPeekHeight(0); // Remove this line to hide a dark background if you manually hide the dialog.
        }
    });
}

Solution 2:

This worked for me and was the cleanest approach:

overridefunonCreateDialog(savedInstanceState: Bundle?): Dialog {
    val dialog = BottomSheetDialog(requireContext(), theme)
    dialog.behavior.state = BottomSheetBehavior.STATE_EXPANDED
    return dialog
}

Solution 3:

Thanks to @avez raj and Prevent dismissal of BottomSheetDialogFragment on touch outside I wrote in onCreateDialog().

overridefunonCreateDialog(savedInstanceState: Bundle?): Dialog {
    val dialog = super.onCreateDialog(savedInstanceState)

    dialog.setOnShowListener {
        val bottomSheet = dialog.findViewById<View>(
            com.google.android.material.R.id.design_bottom_sheet) as? FrameLayout
        val behavior = BottomSheetBehavior.from(bottomSheet)
        behavior.state = BottomSheetBehavior.STATE_EXPANDED
    }

    return dialog
}

Currently I use MakinTosH solution, it is shorter.

Solution 4:

The ViewTreeObserver solution did not work for me, but I found a superior solution here and converted it to Kotlin. This one doesn't have the expensive computational waste which comes with a ViewTreeObserver and nicely bundles the functionality into the class.

classExpandedBottomSheetDialog(context: Context) : BottomSheetDialog(context) {

    overridefunshow() {
        super.show()
        // androidx should use: com.google.android.material.R.id.design_bottom_sheetval view = findViewById<View>(R.id.design_bottom_sheet)
        view!!.post {
            val behavior = BottomSheetBehavior.from(view)
            behavior.setState(BottomSheetBehavior.STATE_EXPANDED)
        }
    }
}

Solution 5:

You can simply do the following:

overridefunonViewCreated(view: View, savedInstanceState: Bundle?) {
    super.onViewCreated(view, savedInstanceState)
    dialog?.let {
        val sheet = it as BottomSheetDialog
        sheet.behavior.state = BottomSheetBehavior.STATE_EXPANDED
    }

    // rest of your stuff
}
