我遇到了一个奇怪的问题:片段底部有一个空白区域,我无法摆脱它。值得一提的是,如果我点击任何按钮,这个空间就会消失。
任何帮助表示赞赏!请在下面找到截图和布局代码。

调试奇怪空格和边距的最佳方法是使用XML快照。
在Android studio
中,点击&#34; Android device monitor
&#34;按钮(绿色机器人图标)
在设备监视器中,确保在左窗格中选择了您的设备,然后单击&#34; Dump view hierarchy
&#34;按钮(3个电话图标)。
然后,您应该看到可见屏幕的屏幕截图,其中xml在右侧创建了它。
您可以将鼠标悬停在底部间距上,以查看xml中的来源。

正如所建议的@marmor所使用的Android设备监视器,并显示该片段的根目录存在问题。因此,我决定遵循@DanielNugent的建议并制作片段的CoordinatorLayout根布局,之后奇数空格消失。
答案 2 :(得分:0)
在我的情况下,问题不仅出现在CoordinatorLayout
和Activity
的{{1}}中(正如Orkhan Gasimli建议的那样,我在Fragment
中变成了ConstraintLayout
)。
Fragment
(Android How to adjust layout in Full Screen Mode when softkeyboard is visible)在全屏模式下调整布局时出现问题。首先是全屏显示,然后更改为通常的样式,并出现空白(SoftInputAssist
比片段容器有更多的空间)。在这种情况下,请移除id/content
并查看https://stackoverflow.com/a/52850584/2914140。
