工具栏上的中心标题 [英] Center title on ToolBar
问题描述
我有问题，我无法将标题放在工具栏中(@ + id/toolbar_title).我试图放一个RelativeLayout，使用layout_gravity:center，但是不起作用.我添加了颜色来区分布局，但是我还不能发布图片.
I have a problem, I can't center my title in my Toolbar (@+id/toolbar_title). I tried to put a RelativeLayout, use layout_gravity: center but it doesn't work. I have added colors to distinguish the layout but I can't post pictures yet.

推荐答案
在工具栏中居中放置文本违反了Android设计标准.我认为这就是您在实现此目标时遇到问题的原因.我不会尝试调整您的文本对齐方式，以确保您的应用适合Android生态系统.
Centering the Text in the Toolbar is against Android design standards. I think this is why you are having issues accomplishing this. I would not try to adjust your text alignment, which will insure your app fits within the Android ecosystem.

我不是在回答您将如何做您要问的事情，而是建议您一开始就不要做(使用标准格式，这对您来说会更容易).
I am not answering how you WOULD do what you are asking, but suggesting that you DON'T do it in the first place (use the standard format, and this will be easier for you).
