推荐答案

请参阅在Android SDK目录。

See in the android sdk directory.

在 \平台\ android的-X \ DATA \水库\值\的themes.xml ：

    <item name="textAppearanceLarge">@android:style/TextAppearance.Large</item>
    <item name="textAppearanceMedium">@android:style/TextAppearance.Medium</item>
    <item name="textAppearanceSmall">@android:style/TextAppearance.Small</item>

在 \平台\ android的-X \ DATA \水库\值\ styles.xml ：

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

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

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

TextAppearance.Large 表示风格从 TextAppearance 风格的继承，你必须跟踪它也是，如果你想看到一个风格的完整定义。

TextAppearance.Large means style is inheriting from TextAppearance style, you have to trace it also if you want to see full definition of a style.
