我假设你使用的是 XML 布局.

I'm assuming you're using XML layout.

<TextView  
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:gravity="center"
    android:text="@string/**yourtextstring**"
/>

您也可以根据需要使用重力center_vertical或center_horizo​​ntal.

You can also use gravity center_vertical or center_horizontal according to your need.

正如@stealthcopter 所说，在java 中:.setGravity(Gravity.CENTER);.

As @stealthcopter commented, in java: .setGravity(Gravity.CENTER);.

对于 Kotlin 用户，.gravity = Gravity.CENTER

And for Kotlin users, .gravity = Gravity.CENTER
