我正在我的Android应用程序中创建通知,并希望在我的首选项中有一个选项来设置用于通知的声音。我知道在“设置”应用程序中,您可以从列表中选择默认通知声音。该列表来自哪里,是否有办法在我的应用程序中显示相同的列表?

只需从我的某个应用程序中复制/粘贴一些代码,这些代码可以满足您的需求。
这是一个标记为“set ringtone”或类似内容的按钮的onClick处理程序:
Intent intent = new Intent(RingtoneManager.ACTION_RINGTONE_PICKER);
intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TYPE, RingtoneManager.TYPE_NOTIFICATION);
intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TITLE, "Select Tone");
intent.putExtra(RingtoneManager.EXTRA_RINGTONE_EXISTING_URI, (Uri) null);
this.startActivityForResult(intent, 5);
此代码捕获用户做出的选择:
@Override
protected void onActivityResult(final int requestCode, final int resultCode, final Intent intent)
{
if (resultCode == Activity.RESULT_OK && requestCode == 5)
{
Uri uri = intent.getParcelableExtra(RingtoneManager.EXTRA_RINGTONE_PICKED_URI);
if (uri != null)
{
this.chosenRingtone = uri.toString();
}
else
{
this.chosenRingtone = null;
}
}
}
另外,我建议我的用户从Android电子市场安装“Rings Extended”应用程序。然后,无论何时在他们的设备上打开此对话框,例如从我的应用程序或手机的设置菜单,用户都可以选择选择存储在其设备上的任何mp3,而不仅仅是内置的铃声。

或者只是将其添加到首选项XML中:
<RingtonePreference android:showDefault="true"
android:key="Audio" android:title="Alarm Noise"
android:ringtoneType="notification" />
我的示例XML的完整内容仅用于上下文:
<?xml version="1.0" encoding="UTF-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<EditTextPreference android:title="Some value"
android:key="someval"
android:summary="Please provide some value" />
<EditTextPreference android:title="Some other value"
android:key="someval2"
android:summary="Please provide some other value" />
<RingtonePreference android:showDefault="true"
android:key="Audio" android:title="Alarm Noise"
android:ringtoneType="notification" />
</PreferenceScreen>

这是我用来获取手机中可用通知声音列表的方法:)
public Map<String, String> getNotifications() {
RingtoneManager manager = new RingtoneManager(this);
manager.setType(RingtoneManager.TYPE_NOTIFICATION);
Cursor cursor = manager.getCursor();
Map<String, String> list = new HashMap<>();
while (cursor.moveToNext()) {
String notificationTitle = cursor.getString(RingtoneManager.TITLE_COLUMN_INDEX);
String notificationUri = cursor.getString(RingtoneManager.URI_COLUMN_INDEX);
list.put(notificationTitle, notificationUri);
}
return list;
}
编辑:这是关于如何在NotificationCompat.Builder中设置声音的注释。相反,该方法获取手机使用的铃声ID,而不是其他方法获得的人类可读标题。结合uri和id,你就有了铃声的位置。
public ArrayList<String> getNotificationSounds() {
RingtoneManager manager = new RingtoneManager(this);
manager.setType(RingtoneManager.TYPE_NOTIFICATION);
Cursor cursor = manager.getCursor();
ArrayList<String> list = new ArrayList<>();
while (cursor.moveToNext()) {
String id = cursor.getString(RingtoneManager.ID_COLUMN_INDEX);
String uri = cursor.getString(RingtoneManager.URI_COLUMN_INDEX);
list.add(uri + "/" + id);
}
return list;
}
上面的代码将返回一个字符串列表,例如&#34; content:// media / internal / audio / media / 27&#34; ..然后您可以传递其中一个字符串作为一个Uri进入.setSound()就像:
.setSound(Uri.parse("content://media/internal/audio/media/27"))
希望足够清楚:)

public void listRingtones() {
RingtoneManager manager = new RingtoneManager(this);
manager.setType(RingtoneManager.TYPE_NOTIFICATION);
// manager.setType(RingtoneManager.TYPE_RINGTONE);//For Get System Ringtone
Cursor cursor = manager.getCursor();
while (cursor.moveToNext()) {
String title = cursor.getString(RingtoneManager.TITLE_COLUMN_INDEX);
String uri = manager.getRingtoneUri(cursor.getPosition());
String ringtoneName= cursor.getString(cursor.getColumnIndex("title"));
Log.e("All Data", "getNotifications: "+ title+"-=---"+uri+"------"+ringtoneName);
// Do something with the title and the URI of ringtone
}
}

这是另一种方法(在Kotlin中),它是根据该问题的其他答案构建的,该方法允许您指定音调的名称,然后播放它:
fun playErrorTone(activity: Activity, context: Context, notificationName: String = "Betelgeuse") {
val notifications = getNotificationSounds(activity)
try {
val tone = notifications.getValue(notificationName)
val errorTone = RingtoneManager.getRingtone(context, Uri.parse(tone))
errorTone.play()
} catch (e: NoSuchElementException) {
try {
// If sound not found, default to first one in list
val errorTone = RingtoneManager.getRingtone(context, Uri.parse(notifications.values.first()))
errorTone.play()
} catch (e: NoSuchElementException) {
Timber.d("NO NOTIFICATION SOUNDS FOUND")
}
}
}
private fun getNotificationSounds(activity: Activity): HashMap<String, String> {
val manager = RingtoneManager(activity)
manager.setType(RingtoneManager.TYPE_NOTIFICATION)
val cursor = manager.cursor
val list = HashMap<String, String>()
while (cursor.moveToNext()) {
val id = cursor.getString(RingtoneManager.ID_COLUMN_INDEX)
val uri = cursor.getString(RingtoneManager.URI_COLUMN_INDEX)
val title = cursor.getString(RingtoneManager.TITLE_COLUMN_INDEX)
list.set(title, "$uri/$id")
}
return list
}
可能需要进行一些重构和优化,但是您应该了解一下。
