解決使用BottomSheetDialog底部虛擬導航欄NavigationBar的顏色

最新版本的BottomSheetDialog狀態列發黑問題已經沒有了但是虛擬導航欄還是會發黑。
華為手機在使用BottomSheetDialog的時候底部虛擬導航欄總是黑色的看著和App整個UI不搭配

這裡可以看到底部是黑色，要想解決需要單獨為底部虛擬導航欄設定一下

    @RequiresApi(api = Build.VERSION_CODES.M)
    private void setWhiteNavigationBar(@NonNull Dialog dialog) {
        Window window = dialog.getWindow();
        if (window != null) {
            DisplayMetrics metrics = new DisplayMetrics();
            window.getWindowManager().getDefaultDisplay().getMetrics(metrics);

            GradientDrawable dimDrawable = new GradientDrawable();

            GradientDrawable navigationBarDrawable = new GradientDrawable();
            navigationBarDrawable.setShape(GradientDrawable.RECTANGLE);
            navigationBarDrawable.setColor(Color.WHITE);//這裡設定顏色

            Drawable[] layers = {dimDrawable, navigationBarDrawable};

            LayerDrawable windowBackground = new LayerDrawable(layers);
            windowBackground.setLayerInsetTop(1, metrics.heightPixels);

            window.setBackgroundDrawable(windowBackground);
        }
    }

當然整個設定方法我也是從別人那裡學的，地址如下

上面操後就Ok了，效果如下

完整程式碼如下

//標籤選擇頁面
public class TagDataSelectFragment extends BottomSheetDialogFragment {


    @NonNull
    @Override
    public Dialog onCreateDialog(@Nullable Bundle savedInstanceState) {
        BottomSheetDialog dialog = new BottomSheetDialog(getActivity());
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O_MR1) {
            setWhiteNavigationBar(dialog);
        }

        return dialog;
    }

    @Override
    public void onStart() {
        super.onStart();
        //獲取dialog物件
        BottomSheetDialog dialog = (BottomSheetDialog) getDialog();
        Window window = dialog.getWindow();
        //設定Dialog背景透明
        window.findViewById(R.id.design_bottom_sheet).setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
    }

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

    @Override
    public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
    }


    @RequiresApi(api = Build.VERSION_CODES.M)
    private void setWhiteNavigationBar(@NonNull Dialog dialog) {
        Window window = dialog.getWindow();
        if (window != null) {
            DisplayMetrics metrics = new DisplayMetrics();
            window.getWindowManager().getDefaultDisplay().getMetrics(metrics);

            GradientDrawable dimDrawable = new GradientDrawable();
            
            GradientDrawable navigationBarDrawable = new GradientDrawable();
            navigationBarDrawable.setShape(GradientDrawable.RECTANGLE);
            navigationBarDrawable.setColor(Color.WHITE);

            Drawable[] layers = {dimDrawable, navigationBarDrawable};

            LayerDrawable windowBackground = new LayerDrawable(layers);
            windowBackground.setLayerInsetTop(1, metrics.heightPixels);

            window.setBackgroundDrawable(windowBackground);
        }
    }

}
