默认值&“大"&“中&"的dpi值和“小型"文字检视Android [英] dpi value of default "large", "medium" and "small" text views android

问题描述

文档(或任何人)是否谈论默认的dpi值

Does the documentation ( or anyone) talks about the dpi values of the default

• 大TextView {android:textAppearance="?android:attr/textAppearanceLarge"}
• 中等TextView {android:textAppearance="?android:attr/textAppearanceMedium"}
• 小型TextView {android:textAppearance="?android:attr/textAppearanceSmall"}

• Large TextView {android:textAppearance="?android:attr/textAppearanceLarge"}
• Medium TextView {android:textAppearance="?android:attr/textAppearanceMedium"}
• Small TextView { android:textAppearance="?android:attr/textAppearanceSmall"}

SDK中的小工具吗?

widgets in the SDK ?

换句话说，我们可以在不使用android:textAppearance属性的情况下复制这些文本视图的外观吗?

To put it in another way, can we replicate the appearance of these text views without using the android:textAppearance attribute?

推荐答案

请参阅android sdk目录.

See in the android sdk directory.

在\platforms\android-X\data\res\values\themes.xml中:

    <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\platforms\android-X\data\res\values\styles.xml中:

<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表示样式是从TextAppearance样式继承的，如果要查看样式的完整定义，也必须对其进行跟踪.

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.
