我有一个文本到语音的应用程序，用户可以选择一种语言，还可以选择男性或女性的声音。的问题是，对于每一种语言有用于称为男性和女性的声音不同的字符串，但在我preference我只有两个选项（男性和女性）。

I have a text to speech application where the user can select a language and also select a male or female voice. The problem is that for each language there are different strings used to called the male and female voice but in my preference I only have two options (male and female).

<string-array name="Language">
    <item>English (US)</item>
    <item>English (UK)</item>
    <item>French (France)</item>
    <item>Spanish (Spain)</item>
    <item>Italian</item>
</string-array>

<string-array name="languageAlias">
    <item>"en-US"</item>
    <item>"en-GB"</item>
    <item>"fr-FR"</item>
    <item>"es-ES"</item>
    <item>"it-IT"</item>
</string-array>

<string-array name="Voice">
    <item>Male</item>
    <item>Female</item>
</string-array>

<string-array name="VoiceAlias">
    <item>"usenglishmale"</item>
    <item>"usenglishfemale"</item>
    <item>"ukenglishmale"</item>
    <item>"ukenglishfemale"</item>
    <item>"eurfrenchmale"</item>
    <item>"eurfrenchfemale"</item>
    <item>"eurspanishmale"</item>
    <item>"eurspanishfemale"</item>
    <item>"euritalianmale"</item>
    <item>"euritalianfemale"</item>        
</string-array>

我试图找到一种方法，仅供参考，相关的公视所选择的语言女voiceAlias​​。是否有可能在这里做这个或做我必须写一些code选择这改变了voiceAlias​​阵列取决于语言的价值？

I'm trying to find a way to only reference the relevant male and female voiceAlias depending on the language selected. Is it possible to do this here or do I have to write some code which changes the values of the voiceAlias array depending on the language selected?

在此先感谢

好了，你可以用两个目录preference 和一个在preferenceChangeListener 每个。首先，XML：

Ok, you can accomplish this with two ListPreferences and an OnPreferenceChangeListener for each. First the XML:

<ListPreference 
    android:key="language_preference"
    android:title="Language"
    android:entries="@array/Language"
    android:entryValues="@array/languageAlias"/>

<ListPreference 
    android:key="gender_preference"
    android:title="Gender"
    android:entries="@array/Voice"
    android:entryValues="@array/VoiceData"/>

让我们在RES /价值/ array.xml一个新的条目：

Let's make a new entry in res/values/array.xml:

<integer-array name="VoiceData">
    <item>0</item>
    <item>1</item>
</integer-array>

现在，在你的 preferenceActivity 的延伸，我们将采取哪些坚持你的共享$ P $的字符串值pferences ，并从他们创造的共享preferences 从VoiceAlias​​获取其值一个完全新的条目。

And now in your extention of PreferenceActivity, we're going to take the string values which persist in your SharedPreferences and from them create a completely new entry in the SharedPreferences which gets its value from "VoiceAlias".

SharedPreferences shareprefs = getPreferenceManager().getSharedPreferences();
Resources resources = YourContext.getResources();

private void makeVoiceData() {
    String languageData = shareprefs.getString("language_preference", "en-US");
    int genderData = shareprefs.getInteger("gender_preference", 0);
    String[] voiceAlias = resources.getStringArray(R.array.VoiceAlias);

    int a = 0
    String[] languageAlias = resources.getStringArray(R.array.languageAlias);
    for (a ; a < languageAlias.length ; a++) {
        if (languageAlias[a].equals(languageData)) {
            break;
        }
    }

    shareprefs.putString("VoiceAlias", voiceAlias[(2 * a) + genderData]);
}

ListPreference language_preference = getPreference("language_preference");
ListPreference gender_preference = getPreference("gender_preference");

language_preference.setOnPreferenceChangeListener(new OnPreferenceChangeListener() {
    public boolean onPreferenceChanged(Preference preference, Object newValue) {
        shareprefs.putString("language_preference", (String) newValue);
        makeVoiceData();
    }
});

gender_preference.setOnPreferenceChangeListener(new OnPreferenceChangeListener() {
    public boolean onPreferenceChanged(Preference preference, Object newValue) {
        shareprefs.putString("gender_preference", (String) newValue);
        makeVoiceData();
    }
});
