Android全屏弹出Dialog显示状态栏和导航栏的问题及解决方案
UqndTf__的博客
09-20 4046
然而，当我们尝试实现这样的Dialog时，可能会遇到一个问题：状态栏和导航栏在全屏Dialog中仍然可见，这可能会影响用户体验。然后，我们将全屏Dialog的内容设置为之前创建的布局文件。当我们使用Android中的Dialog类创建一个全屏的Dialog时，状态栏和导航栏通常会继续显示在全屏Dialog的顶部和底部，这可能会导致Dialog与应用的主题不一致，给用户带来困惑。通过上述步骤，我们成功地创建了一个全屏的Dialog，并隐藏了状态栏和导航栏，以实现更好的用户体验。方法来显示全屏Dialog。

Android中全屏Dialog的实现
FynnJason的技术屋

Dialog是APP开发中常用的控件，同Activity类似，拥有独立的Window窗口，但是Dialog跟Activity还是有一定区别的，最明显的就是：默认情况下Dialog不是全屏的，所以布局实现不如Activity舒服，比如顶部对齐，底部对齐、边距、宽度、高度等。如果将Dialog定义成全屏的就会省去很多问题，可以完全按照常用的布局方式来处理。网上实现方式有不少，一般情况下也都能奏效，不过
