我想在颤动中访问我的系统铃声

Question

有什么方法可以使用flutter获取手机的所有铃声，并将选择的铃声设置为我的应用的默认铃声？

提前致谢

我设法使用本机代码完成了它

1. 首先，您将在 Flutter 端创建这些东西。

   
   // here where your ringtones will be stored
   List<Object?> result = ['Andromeda'];
   
   // this is the channel that links flutter with native code
   static const channel = MethodChannel('com.example.pomo_app/mychannel');
   
   // this method waits for results from the native code 
   Future<void> getRingtones() async {
       try {
         result = await channel.invokeMethod('getAllRingtones');
       } on PlatformException catch (ex) {
         print('Exception: $ex.message');
       }
     }
   
   

2. 知道您需要实现本机代码。转到 MainActivity.kt

   // add the name of the channel that we made in flutter code
   private val channel = "com.example.pomo_app/mychannel"
   
   // add this method to handle the calls from flutter
   MethodChannel(flutterEngine.dartExecutor.binaryMessenger, channel)
     .setMethodCallHandler { call, result ->
               when (call.method) {
                   "getAllRingtones" -> {
                       result.success(getAllRingtones(this))
                   }
   
   
   
   // this function will return all the ringtones names as a list
   private fun getAllRingtones(context: Context): List<String> {
   
     val manager = RingtoneManager(context)
     manager.setType(RingtoneManager.TYPE_RINGTONE)
   
     val cursor: Cursor = manager.cursor
   
     val list: MutableList<String> = mutableListOf()
     while (cursor.moveToNext()) {
       val notificationTitle: String = cursor.getString(RingtoneManager.TITLE_COLUMN_INDEX)
       list.add(notificationTitle)
     }
     return list
   }
   

就是这样，希望对您有所帮助。有任何问题请告诉我。
