How to implement RingtonePreference in PreferenceFragmentCompat?

Question

I create an application using one AppCompactActivity, and all other views use Fragment. Therefore, I would like to use PreferenceFragmentCompat. But I get the following error when I create this.

Please let me know if there is a way to implement Ringtone preference in PreferenceFragmentCompat?

Answer 1

Not my decision, but I will publish it anyway, because it works.

In your preferences XML resource, change RingtonePreference to Preference. Then in your implementation of PreferenceFragment add:

 @Override public boolean onPreferenceTreeClick(Preference preference) { if (preference.getKey().equals(KEY_RINGTONE_PREFERENCE)) { 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); intent.putExtra(RingtoneManager.EXTRA_RINGTONE_SHOW_SILENT, true); intent.putExtra(RingtoneManager.EXTRA_RINGTONE_DEFAULT_URI, Settings.System.DEFAULT_NOTIFICATION_URI); String existingValue = getRingtonePreferenceValue(); // TODO if (existingValue != null) { if (existingValue.length() == 0) { // Select "Silent" intent.putExtra(RingtoneManager.EXTRA_RINGTONE_EXISTING_URI, (Uri) null); } else { intent.putExtra(RingtoneManager.EXTRA_RINGTONE_EXISTING_URI, Uri.parse(existingValue)); } } else { // No ringtone has been selected, set to the default intent.putExtra(RingtoneManager.EXTRA_RINGTONE_EXISTING_URI, Settings.System.DEFAULT_NOTIFICATION_URI); } startActivityForResult(intent, REQUEST_CODE_ALERT_RINGTONE); return true; } else { return super.onPreferenceTreeClick(preference); } } @Override public void onActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == REQUEST_CODE_ALERT_RINGTONE && data != null) { Uri ringtone = data.getParcelableExtra(RingtoneManager.EXTRA_RINGTONE_PICKED_URI); if (ringtone != null) { setRingtonPreferenceValue(ringtone.toString()); // TODO } else { // "Silent" was selected setRingtonPreferenceValue(""); // TODO } } else { super.onActivityResult(requestCode, resultCode, data); } }

There is currently no support in the music library. You need to use the framework version or create your own. I think he will appear soon

If you need a version of XAMARIN.Droid :

  public override void OnActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == REQUEST_CODE_ALERT_RINGTONE && data != null) { var ringtone = data.GetParcelableExtra(RingtoneManager.ExtraRingtonePickedUri); if (ringtone != null) { SetRingtonePreferenceValue(ringtone.ToString()); } else { // "Silent" was selected SetRingtonePreferenceValue(""); } } else { base.OnActivityResult(requestCode, resultCode, data); } } public override bool OnPreferenceTreeClick(Android.Support.V7.Preferences.Preference preference) { if (preference.Key == KEY_RINGTONE_PREFERENCE) { Intent intent = new Intent(RingtoneManager.ActionRingtonePicker); intent.PutExtra(RingtoneManager.ExtraRingtoneType, (int)RingtoneType.Notification); intent.PutExtra(RingtoneManager.ExtraRingtoneShowDefault, true); intent.PutExtra(RingtoneManager.ExtraRingtoneShowSilent, true); intent.PutExtra(RingtoneManager.ExtraRingtoneDefaultUri, Android.Provider.Settings.System.DefaultRingtoneUri); string existingValue = GetRingtonePreferenceValue(); if (existingValue != null) { if (existingValue.Length == 0) { // Select "Silent" intent.PutExtra(RingtoneManager.ExtraRingtoneExistingUri, (Android.Net.Uri)null); } else { intent.PutExtra(RingtoneManager.ExtraRingtoneExistingUri, Android.Net.Uri.Parse(existingValue)); } } else { // No ringtone has been selected, set to the default intent.PutExtra(RingtoneManager.ExtraRingtoneExistingUri, Android.Provider.Settings.System.DefaultRingtoneUri); } StartActivityForResult(intent, REQUEST_CODE_ALERT_RINGTONE); return true; } return base.OnPreferenceTreeClick(preference); } void SetRingtonePreferenceValue(string ringtone) { var editor = prefs.Edit(); editor.PutString(KEY_RINGTONE_PREFERENCE, ringtone); editor.Commit(); } string GetRingtonePreferenceValue() { return prefs.GetString(KEY_RINGTONE_PREFERENCE, "content://settings/system/notification_sound"); }
