使用 strings.xml 文件

字符串资源为应用程序提供可选的文本样式和格式的文本字符串。有三种类型的资源可以为你的应用程序提供字符串:

字符串

XML resource that provides a single string.

句法:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="string_name">text_string</string>
</resources>

并在布局中使用此字符串:

<TextView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/string_name" />

字符串数组

XML resource that provides an array of strings.

句法:

    <resources>
<string-array name="planets_array">
    <item>Mercury</item>
    <item>Venus</item>
    <item>Earth</item>
    <item>Mars</item>
</string-array>

用法

Resources res = getResources();
String[] planets = res.getStringArray(R.array.planets_array);

数量字符串(复数)

XML resource that carries different strings for pluralization. 

句法:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <plurals
        name="plural_name">
        <item
            quantity=["zero" | "one" | "two" | "few" | "many" | "other"]
            >text_string</item>
    </plurals>
</resources>

用法:

int count = getNumberOfsongsAvailable();
Resources res = getResources();
String songsFound = res.getQuantityString(R.plurals.plural_name, count, count);
