【已解决】Android中RelativeLayout的字符水平(垂直居中)对齐

【背景】

此处Android中显示出来的TextView中的内容,水平中间不对其。

想要实现水平居中对齐。

【折腾过程】

1.搜:

android RelativeLayout horizontal center

参考:

android – TextView horizontal center in RelativeLayout – Stack Overflow

试过了:

android:layout_centerHorizontal="true"

但没用。

2.后来看到:

relativelayout – Android Relative Layout Align Center – Stack Overflow

去试了试:

android:layout_centerVertical="true"

才明白:

我上面是错误的搜了horizontal ,实际上该去搜Vertical才对。

现在效果是所需要的了:

android text horizontal center align

 

【总结】

想要水平居中对齐,则只需要去设置:

android:layout_centerVertical="true"

即可。

 

【引申】

更多的其他参数,可以去官网:
