String.xml

<!-- Material Design Icons --> 
<string name="material_icon_bike">&#xe915;</string> 
<string name="material_icon_go">&#xea04;</string> 
<string name="material_icon_sleep">&#xe9c2;</string> 
<string name="material_icon_eat">&#xeac6;</string> 
<string name="material_icon_play">&#xe831;</string> 
<string name="material_icon_drink">&#xea08;</string> 
<string name="material_icon_party">&#xe937;</string> 

什么是这些字符串   ... 以及如何字符串&#xea08变为图标的含义是什么？

我在资产/字体中有一个字体文件（MaterialDesignIcons.ttf）？

我不知道这种方法的原理是什么？

如何字符串成为图标？

字符串可以变成图标，（:)）它的字符串编码技术，这里是HTML实体（十六进制）编码。有很多编码技术。

比方说当你在你的智能手机中输入:)然后变成笑脸表情符号，还有编码发挥作用。

你可以找到Unique Characters list

我有资产/字体的字体文件（MaterialDesignIcons.ttf）这些符号列表？

如果我理解正确，你的问是把.ttf文件放在字体文件夹中？

此.ttf与这些图标之间没有任何关系。

我不知道这种方法的原理是什么？

希望大家通过看Unique Characters list

注意列表获取的原则：如果你想改变这些图标的颜色，你需要找出它们的字符串值
