Android XML字符串

发表于 更新于 分类于 阅读次数： 本文字数： 4.6k 阅读时长 ≈ 4 分钟

Android在开发过程中，一些特殊字符时无法直接在 strings.xml 文件中写，需要用对应的转义字符代替或者在特殊符号（比如：´，" 等待）前添加 \ ，比如一个 TextView 控件中，需要动态替换其中的一些数据，再比如需要调整 TextView 字体的一些HTML样式（比如：粗体，斜体，下划线等），虽然这些都可以用 TextView 去修改，但更简单的方法是设置string提供的属性即可

<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:tools="http://schemas.android.com/tools">
    <!-- 
    无法直接使用I'm developer
    <string name="name_introduce">I'm developer</string> 
    -->
    <!-- 解决方法一 转义字符代替 -->
    <string name="name_introduce">I&#039;m developer</string>
    <!-- 解决方法二 使用 \  -->
    <string name="name_introduces">I\'m developer</string>
</resources>

动态替换或拼接

  • %n$ms：代表输出的是字符串，n代表是第几个参数，设置m的值可以在输出之前放置空格
  • %n$md：代表输出的是整数，n代表是第几个参数，设置m的值可以在输出之前放置空格
  • %n$mf：代表输出的是浮点数，n代表第几个参数，m在浮点类型之前放置几个空格

    <!-- 
    %1$s 第一个参数，对应Jerry
    %2$d 第二个参数，对应36
    %3$4.2f 第三个参数，对应 195.1255 ，但保留两位小数，实际显示195.13
    -->
    <string name="welcome_messages">Hello, %1$s, You have %2$d new messages. total cost %3$4.2f</string>
</resources>
