我假设您正在使用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_horizontal.

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);

and as @stealthcopter commented in java: .setGravity(Gravity.CENTER);
