StatusBarUtil 类中 setColor 适配问题

 public static void setColor(Activity activity, @ColorInt int color, @IntRange(from = 0, to = 255) int statusBarAlpha) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
            activity.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
            activity.getWindow().setStatusBarColor(calculateStatusColor(color, statusBarAlpha));
        } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
            ViewGroup decorView = (ViewGroup) activity.getWindow().getDecorView();
            View fakeStatusBarView = decorView.findViewById(FAKE_STATUS_BAR_VIEW_ID);
            if (fakeStatusBarView != null) {
                if (fakeStatusBarView.getVisibility() == View.GONE) {
                    fakeStatusBarView.setVisibility(View.VISIBLE);
                }
                fakeStatusBarView.setBackgroundColor(calculateStatusColor(color, statusBarAlpha));
            } else {
                decorView.addView(createStatusBarView(activity, color, statusBarAlpha));
            }
            setRootView(activity);
        }
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            activity.getWindow().getDecorView().setSystemUiVisibility(
                    View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);
        }
    }
