/res/values 目录详解

/res/values 下可以放置的文件有：

• strings.xml 
• arrays.xml
• dimens.xml
• colors.xml
• styles.xml

2、arrays.xml

详解利用arrays.xml文件存放数组，并读取的过程。

方式1：

    <string-array name="proto">
        <item>刀兵</item>
        <item>龙骑</item>
        <item>黑暗圣堂</item>
        <item>电兵</item>
    </string-array>
    <string-array name="zerg">
        <item>小狗</item>
        <item>飞龙</item>
        <item>刺蛇</item>
    </string-array>
    <string-array name="terran">
        <item>机枪兵</item>
        <item>护士MM</item>
        <item>幽灵</item>
        <item>大舰</item>
    </string-array>

int[] resIds = new int[] { R.array.proto, R.array.zerg, R.array.terran };
String[] armType = new String[] { "神族兵种：", "虫族兵种：", "人族兵种：" };
getArms(resIds, armType);

private void getArms(int[] ids, String[] typeNames) {
    int len1 = ids.length;
    String[][] arms = new String[len1][];

    for (int i = 0; i < len1; i++) {
        String[] armsType = this.getResources().getStringArray(ids[i]);
        int len2 = armsType.length;
        arms[i] = new String[len2];
        System.out.println(typeNames[i]);
        for (int j = 0; j < len2; j++) {
            arms[i][j] = armsType[j];
            System.out.print(arms[i][j] + " ");
        }
        System.out.println();
    }
}

输出结果：

　　　　

方式2：

    <string-array name="planet">
        <item>太阳</item>
        <item>水星,金星,地球,火星,木星,土星,天王星,海王星</item>
        <item>哈雷,恩克</item>
    </string-array>

String[] planetType = new String[] { "恒星：", "行星：", "彗星：" };
getPlanets(planetType);

private void getPlanets(String[] typeNames) {
    String[] ids = this.getResources().getStringArray(R.array.planet);
    int len1 = ids.length;
    String[][] planets = new String[len1][];
    for (int i = 0; i < len1; i++) {
        String[] planetArr = ids[i].split(",");
        int len2 = planetArr.length;
        planets[i] = new String[len2];
        System.out.println(typeNames[i]);
        for (int j = 0; j < len2; j++) {
            planets[i][j] = planetArr[j];
            System.out.print(planetArr[j]+" ");
        }
        System.out.println();
    }
}

输出结果：

　　　　

方式3：

    <string-array name="china">
        <item>@array/guangdong</item>
        <item>@array/beijing</item>
        <item>@array/yunnan</item>
    </string-array>
    <string-array name="guangdong">
        <item>广州</item>
        <item>深圳</item>
    </string-array>
    <string-array name="beijing">
        <item>北京</item>
    </string-array>
    <string-array name="yunnan">
        <item>昆明</item>
        <item>大理</item>
        <item>丽江</item>
    </string-array>

　　

String[] province = new String[] { "广东：", "北京：", "云南：" };
getCities(province);

private void getCities(String[] names) {
    TypedArray typedArray = getResources().obtainTypedArray(R.array.china);
    int len1 = typedArray.length();
    String[][] cities = new String[len1][];
    for (int i = 0; i < len1; i++) {
        int resArrID =  typedArray.getResourceId(i, 0);
        String[] cityArr = this.getResources().getStringArray(resArrID);
        int len2 = cityArr.length;
        cities[i] = new String[len2];
        System.out.println(names[i]);
        for (int j = 0; j < len2; j++) {
            cities[i][j] = cityArr[j];
            System.out.print(cityArr[j]+" ");
        }
        System.out.println();
    }
}

输出结果：

　　　　

 对于不同数据类型的读取：

    <string-array name="FourPoets">
            <item>唐伯虎</item>
            <item>祝枝山</item>
            <item>文征明</item>
            <item>徐祯卿</item>
    </string-array>

    <integer-array name="capability">
        <item>99</item>
        <item>96</item>
        <item>90</item>
        <item>85</item>
    </integer-array>
    
    <array name="sex">
        <item>男</item>
            <item>女</item>
    </array>


CharSequence[] name = getResources().getTextArray(R.array.FourPoets);

int[] capability = getResources().getIntArray(R.array.price);

String[] sex = getResources().getStringArray(R.array.sex);

　　默认使用<array>标签，item里面内容需以String数组形式读出。
