目前它只适用于声音4但不适合声音5

这是因为你保存到文件是静态设置的，每次保存R.raw.sound4（你已经写了保存（R.raw.sound4））。 您需要使用您传递给它的变量（ressound）并使用它来决定保存哪个文件。
这样做的最好方法是创建一个声音数组（或者对它们的引用），就像这样（这会在你的java文件的开始处以其他变量减速）：
int[] soundArray = {R.raw.sound1,R.raw.sound2,R.raw.sound3}; // etc...
你可以像这样添加到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，您的保存函数将使用传递的参数来知道要保存哪个文件。 （这是你以前称之为功能的地方）
savering(soundArray[ressound]);
