我不知道这是一个容易解决的愚蠢问题。我有一个铃声选择器,显示默认铃声选项(用于通知)。像这样:
Intent intent = new Intent(RingtoneManager.ACTION_RINGTONE_PICKER);
intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TYPE, RingtoneManager.TYPE_NOTIFICATION);
intent.putExtra(RingtoneManager.EXTRA_RINGTONE_SHOW_DEFAULT, true);
startActivityForResult(intent, RingtoneManager.TYPE_NOTIFICATION);
然后我抓住了结果:
protected void onActivityResult(int requestCode, int resultCode, Intent mRingtone) {
switch (requestCode) {
case RingtoneManager.TYPE_NOTIFICATION:
if (resultCode == RESULT_OK) {
notifToneUri = mRingtone.getParcelableExtra(RingtoneManager.EXTRA_RINGTONE_PICKED_URI);
Ringtone ringtone = RingtoneManager.getRingtone(this, uri);
Log.d(TAG,"Uri = " + notifToneUri.toString() + " and title = " + ringtone.getTitle(this));
}
break;
}
}
发生奇怪的事情,如果我选择“默认通知音”选项,则uri应该是:* content:// settings / system / notification_sound *但是uri是内容:// settings / system / ringtone (这是铃声的默认值,而不是通知)。它与默认警报音相同。
我这样解决了:
if (notifToneUri.equals(Settings.System.DEFAULT_RINGTONE_URI)){
notifToneUri = Settings.System.DEFAULT_NOTIFICATION_URI;
}
好的,这有效...但我想知道是否有更好的方法,或者我做错了。
提前谢谢。

我认为您没有正确检索Uri
。以下是一个示例:
启动RingtoneManager
final Intent ringtone = new Intent(RingtoneManager.ACTION_RINGTONE_PICKER);
ringtone.putExtra(RingtoneManager.EXTRA_RINGTONE_TYPE, RingtoneManager.TYPE_NOTIFICATION);
ringtone.putExtra(RingtoneManager.EXTRA_RINGTONE_SHOW_DEFAULT, true);
ringtone.putExtra(RingtoneManager.EXTRA_RINGTONE_DEFAULT_URI,
RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION));
startActivityForResult(ringtone, 0);
在Uri
Activity.onActivityResult
和标题
if (requestCode == 0 && resultCode == RESULT_OK) {
final Uri uri = data.getParcelableExtra(RingtoneManager.EXTRA_RINGTONE_PICKED_URI);
final Ringtone ringtone = RingtoneManager.getRingtone(this, uri);
// Get your title here `ringtone.getTitle(this)`
}
您可以看到here in the source for Ringtone
,只有当Uri
的权威性等于Settings.AUTHORITY
且永远不会MediaStore.AUTHORITY
时,才会添加前缀。
