字符串.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>

这些字符串是什么意思   ...字符串  如何变成图标？

我在 assets/font 中有一个字体文件 (MaterialDesignIcons.ttf) ??

不知道这个方法的原理是什么？

Answer 1

How String  Becomes icon ?

字符串可以变成图标，(:))它的String编码技术，这里是HTML Entity(hex)编码。有很多编码技术。

假设当您在智能手机中键入 :) 然后变成微笑表情符号时，编码也起作用。

您可以在 Unique Characters list 中找到这些符号的列表

I have a Font File (MaterialDesignIcons.ttf) in the assets/font ??

如果我没理解错的话，你是问把 .ttf 文件放在字体文件夹中？

此 .ttf 与那些图标之间没有任何关系。

I know not what is the principle of this method ?

希望大家看到Unique Characters list的列表就明白原理了

注意: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
