缺少TextAppearances.Micro风格 [英] Missing TextAppearances.Micro style

问题描述

根据 Android开发者设计风格印刷术，有4 TextAppearance S（微型，小型，中型，大型）。

According to Android Developer Design Style for Typography, there are 4 TextAppearances (Micro, Small, Medium, Large).

但没有predefined样式微：

But there is no predefined style for Micro:

?android:attr/textAppearanceMicro
android:style/TextAppearance.Micro

他们没有在Android的源被发现。我缺少什么？

None of them can be found in sources of Android. What am I missing?

推荐答案

好问题！研究一点点后，我没有找到TextAppearance.Micro。

Good question! After researching a little bit, I didn't find any results for "TextAppearance.Micro".

在另一方面，我发现<一个href=\"https://android.googlesource.com/platform/frameworks/base/+/refs/heads/master/core/res/res/values/styles.xml\"相对=nofollow>官方Android源相关的样式资源 TextAppearance 秒。

On the other hand, I found the official Android source for style resource related to TextAppearances.

<style name="TextAppearance.Small">
    <item name="android:textSize">14sp</item>
    <item name="android:textColor">?textColorSecondary</item>
</style>

<style name="TextAppearance.Medium">
    <item name="android:textSize">18sp</item>
</style>

<style name="TextAppearance.Large">
    <item name="android:textSize">22sp</item>
</style>

正如你所看到的，所有的人都只会影响文字的大小（除 TextAppearance.Small ，这也影响文本颜色）。所以，我可以肯定地说，该网站显示的文字大小，因为只有一个准则。在另一方面，你可以随时添加自定义样式，支持 TextAppearance.Micro ！只是里面的 styles.xml 插入此。

As you can see, all of them only affect the text size (except TextAppearance.Small, which also affect the text color). So, I can safely say that the site displays the text sizes as a guideline only. On the other hand, you can always add a custom style to support TextAppearance.Micro! Just insert this inside styles.xml.

<style name="TextAppearance.Micro" parent="@android:style/TextAppearance.Small">
    <item name="android:textSize">12sp</item>
</style>

和使用它像：

<TextView
    ...
    android:textAppearance="@style/TextAppearance.Micro" />

在一个有点相关的说明，当我搜索textAppearanceMicro，我发现在GitHub上3个项目。他们都加入了一些自定义的属性，其中一个是 textAppearanceMicro 。此外，所有的人都使用 ActionBarSherlock 。我不知道是否有之间的连接 textAppearanceMicro 和 ActionBarSherlock ，但我没有找到该属性是在code任何地方使用。

On a bit related note, when I searched "textAppearanceMicro", I found 3 projects on GitHub. All of them adding some custom attributes, which one of them is textAppearanceMicro. Also, all of them are using ActionBarSherlock. I don't know whether there is a connection between textAppearanceMicro and ActionBarSherlock, but I didn't find that attribute was used anywhere in the code.
