当设置带有导航栏和状态栏的全屏时 fitsystemwindows 被忽略

Question

我希望屏幕背景（登录屏幕背景只是渐变）显示在透明工具栏和透明导航栏后面，但需要手动添加填充。目前我将填充添加到工具栏 20dp 以使其看起来也有，但解决方案应该是在容器和工具栏上使用 fitsystemwindows，但它不起作用，因为我们以编程方式设置标志，我认为它会覆盖它们。有没有人有解决办法。我尝试了样式并且它有效但是导航栏不是完全透明它有透明的黑色边框我发现唯一有效的是如果我以编程方式设置标志。有任何想法吗？

        getWindow().setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
    }

        android:paddingTop="20dp" />  <!-- Current solution for padding because fitsystemwindows doesn't work-->
</LinearLayout>
