android - BottomSheetDialogFragment 不是模态的

Question

是否可以使 BottomSheetDialogFragment 不是模态的？这意味着底层内容不会变暗，也不会阻止与其交互。

也许只能通过经典 fragment ？

Answer 1

尝试用这种方式扩展BottomSheetDialogFragment类

public class CustomBottomSheetDialogFragment extends BottomSheetDialogFragment {


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

    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) {
        }
    };

    @Override
    public void setupDialog(Dialog dialog, int style) {
        super.setupDialog(dialog, style);
        View contentView = View.inflate(getContext(), R.layout.dialog_modal, null);
        dialog.setContentView(contentView);
        CoordinatorLayout.LayoutParams layoutParams =
                (CoordinatorLayout.LayoutParams) ((View) contentView.getParent()).getLayoutParams();
        CoordinatorLayout.Behavior behavior = layoutParams.getBehavior();
        if (behavior != null && behavior instanceof BottomSheetBehavior) {
            ((BottomSheetBehavior) behavior).setBottomSheetCallback(mBottomSheetBehaviorCallback);
        }
    }
}
