soft keyboard is covering bottom sheet dialog

Question

I've searched all over the related questions on SO, tried basically all of their solutions, and have gotten nowhere. I want to have a bottom sheet modal dialog with a a few EditText and other components in it, using BottomSheetDialogFragment, which is easy enough.

The problem I am having is that the soft keyboard covers half the dialog. No settings I change seem to make any difference in anything. Did something change in the API? No amount of googling seems to be revealing a solution. What currently happens: keyboard does not cover the edit text that is currently selected, but it covers the dialog below it. I want the whole dialog to be visible at all times and move when the keyboard opens.

Here is my Fragment class:

public class GoalUpdateFormDialogFragment extends BottomSheetDialogFragment {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.goal_update_form, container, false);

        assert getDialog().getWindow() != null;

        getActivity().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
        getDialog().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);

        return view;
    }

}

Here is the dialog layout file I am using:

    android:layout_height="match_parent">

    <RelativeLayout

        android:layout_height="match_parent">

        <LinearLayout

                android:layout_gravity="center"
                android:textAlignment="center"/>

            <Button
                android:id="@+id/pick_image_button"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Pick image"
                android:onClick="onClickPickImage"/>

            <Button
                android:id="@+id/test_comment_box_button"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Test comment box"
                android:onClick="onClickTestCommentBox"/>

            <ImageView

If you have a very large ui on bottomsheet, best thing is to use NestedScrollView with fixed size;

<android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="500dp"
    android:background="@color/colorWhite"
    android:orientation="vertical">

......Other views

</android.support.v4.widget.NestedScrollView>

also have a BottomSheetBehavior like following in your bottomSheet;

define a member variable

private BottomSheetBehavior.BottomSheetCallback mBottomSheetBehaviorCallback = new BottomSheetBehavior.BottomSheetCallback() {

    @Override
    public void onStateChanged(@NonNull View bottomSheet, int newState) {
        if (newState == BottomSheetBehavior.STATE_HIDDEN) {
            dismiss();
        }
    }

    @Override
    public void onSlide(@NonNull View bottomSheet, float slideOffset) {
    }
};

and then set it

@Override
public void setupDialog(Dialog dialog, int style) {
    super.setupDialog(dialog, style);
    View contentView = View.inflate(getContext(), R.layout.content_register, null);
    ButterKnife.bind(this, contentView);
    dialog.setContentView(contentView);

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

    if( behavior != null && behavior instanceof BottomSheetBehavior ) {
        ((BottomSheetBehavior) behavior).setBottomSheetCallback(mBottomSheetBehaviorCallback);
        ((BottomSheetBehavior) behavior).setState(BottomSheetBehavior.STATE_EXPANDED);
    }
}
