Android String.xml 设置加粗字体/修改字体颜色/动态设置修改文案

之前经常使用Spannable

这次主要在String.xml使用：<! $CDATA\[和$ ]>

效果：

html 复制代码

<resources>
    <string name="str_bianse"><![CDATA[变色 <font color="#ff0000">曲项向天歌</font> 白毛浮绿水]]></string>
    <string name="str_jiacu"><![CDATA[加粗1 <b>曲项向天歌</b> 白毛浮绿水]]></string>
    <string name="str_huanhang"><![CDATA[变色、换行 <font color="#ff0000">曲项向天歌</font><br> 白毛浮绿水]]></string>
    <string name="str_xieti"><![CDATA[斜体 <i><font>曲项向天歌</font></i> 白毛浮绿水]]></string>
    <string name="str_xiahuaxian"><![CDATA[下划线 <u>曲项向天歌</u> 白毛浮绿水]]></string>
    <string name="str_xiahuaxian_bianse"><![CDATA[下划线、变色 <u><font color="#ff0000">曲项向天歌</font></u> 白毛浮绿水]]></string>
    <string name="str_zhonghuaxian"><![CDATA[中划线 <s>曲项向天歌</s> 白毛浮绿水]]></string>
    <string name="str_jiacu2"><![CDATA[加粗2 <strong>曲项向天歌</strong> 白毛浮绿水]]></string>
    <string name="str_fangda"><![CDATA[放大 <big>曲项向天歌</big> 白毛浮绿水]]></string>
    <string name="str_souxiao"><![CDATA[缩小 <small>曲项向天歌</small> 白毛浮绿水]]></string>
    <!--    "<"改成HTML转义符&lt-->
    <string name="welcome_messages">Hello, %1$s! You have &lt;b>%2$d new messages&lt;/b></string>
    <!--    内容放在<![CDATA[和]]>里   %1$s 第一个要填充的字符串 %2$d 第二个要填充的int值-->
    <string name="welcome_messages2"><![CDATA[Hello, %1$s! You have <b>%2$d new messages</b>]]></string>
</resources>
