java - 如何为多种屏幕尺寸设置操作栏和标题窗口文本大小？

Question

我想根据屏幕尺寸和分辨率(例如 4"480 x 800 hdpi)设置操作栏的文本大小。我的应用程序开发已经结束，所以现在我只是确保应用程序布局适合所有多个 Android 屏幕尺寸。问题是我无法设置每个布局的标题大小，例如布局正常 hdpi 和布局正常 ldpi，因此在某些设备布局中我放置在标题文本中的文本在模拟器上测试时，由于文本太大，空间不足。这是 styles.xml 代码。

<style name="ActionBar" parent="android:style/Widget.Holo.ActionBar">
<item name="android:background">@color/title_background</item>
<item name="android:titleTextStyle">@style/TextMedium</item>
<item name="android:displayOptions">showTitle</item>
</style>

<style name="TextMedium">
    <item name="android:textSize">16sp</item>
</style>

Answer 1

我认为这个问题类型的最佳解决方案，以及维度的值(value)

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <dimen name="font_size">16sp</dimen>
</resources>

//改成这个

<style name="TextMedium">
    <item name="android:textSize">@dimen/font_size</item>
</style>
