这是因为保存到文件是静态设置的，每次都保存R.raw.sound4（你已经写过savering（R.raw.sound4））。您需要使用传递给它的变量（ressound）并使用它来决定要保存的文件。

执行此操作的最佳方法可能是创建一个声音数组（或对它们的引用），这样做（这是在java文件的开头，其余的可变减速）：

  int[] soundArray = {R.raw.sound1,R.raw.sound2,R.raw.sound3}; // etc...

你会像这样添加到soundManager中（这是你手动添加声音的地方）

  for (int i=0; i<soundArray.length; i++){   // Loops over the sound array
  mSoundManager.addSound(i, soundArray[i]);  // Adds sounds to sound manager
  }

然后你的savering函数将使用传递的参数来知道要保存的文件。（这是你以前称之为函数的地方）

  savering(soundArray[ressound]);
