android - 如何在 TextView 中将文本居中并将部分文本设为粗体

Question

现在，我有一个 2x3 的图像按钮表，我需要在窗口底部包含一个 TextView 这是我为 TextView 准备的:

<TextView
    android:layout_height="wrap_content"
    android:layout_width="match_parent" 
    android:layout_gravity="center_horizontal|bottom"
    android:text = "Hello Connor"
    android:textColor = "#000000"
    android:background = "@drawable/back"/>     
</LinearLayout>
</LinearLayout>
</LinearLayout>

现在它在屏幕底部创建了一个 TextView，但是我需要将框内的文本居中，并且我需要将名称“Connor”加粗。我如何在 XML 中执行此操作？

<?xml version="1.0" encoding="utf-8"?>

没关系，我想通了。我将 textView 的重力设置为居中，并将文本设置为在我的 res/values/strings.xml 文件中定义的字符串“footer”:

<string name="footer">Hello <b>Connor</b></string>

感谢大佬们的帮助!
