如何在res/raw文件夹中将我的应用的自定义铃声添加到铃声首选项 [英] How can I add my app's custom ringtones in res/raw folder to a ringtonepreference

问题描述

我有这个RingtonePreference(来自Android Studio的默认SettingsActivity):

I have this RingtonePreference (from Android Studio's default SettingsActivity):

pref_notification.xml:

pref_notification.xml:

<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
    <RingtonePreference
        android:dependency="notifications_alarm"
        android:key="notifications_alarm_ringtone"
        android:title="@string/pref_title_ringtone"
        android:ringtoneType="notification|all"
        android:defaultValue="content://settings/system/notification_sound" />

SettingsActivity.java:

SettingsActivity.java:

private void setupSimplePreferencesScreen() {
    if (!isSimplePreferences(this)) {
        return;
    }

    // Add 'general' preferences.
    addPreferencesFromResource(R.xml.pref_general);

    // Add 'notifications' preferences, and a corresponding header.
    PreferenceCategory fakeHeader = new PreferenceCategory(this);
    fakeHeader.setTitle(R.string.pref_header_notifications);
    getPreferenceScreen().addPreference(fakeHeader);
    addPreferencesFromResource(R.xml.pref_notification);

    bindPreferenceSummaryToValue(findPreference("notifications_alarm_ringtone"));
}

@TargetApi(Build.VERSION_CODES.HONEYCOMB)
public static class NotificationPreferenceFragment extends PreferenceFragment {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        addPreferencesFromResource(R.xml.pref_notification);

        bindPreferenceSummaryToValue(findPreference("notifications_alarm_ringtone"));
    }
}

我想将我的应用程序的自定义铃声从res/raw文件夹添加到列表中. (我不需要其他应用可以使用它们.)

I would like to add my app's custom ringtones from res/raw folder to the list. (I don't need them to be available for other apps.)

推荐答案

最后，我根据以下答案创建了自己的ExtraRingtonePreference:

Finally I made my own ExtraRingtonePreference based on this answer: In preferences, select my sound just like with RingtonePreference

我将其包括在这里以供将来参考:
