Question

如何将声音设置为长按按钮上的铃声？

在它仅适用于sound4但不sound5

这是因为你保存到文件的设置静态每次都保存R.raw.sound4（你写savering（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。

要做到这一点，最好的办法可能是创造声音的阵列（或它们的引用）像这样（这正好在你的java文件开始与可变减速的其余部分）：

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

哪你会添加到SoundManager类像这样（这正好你在哪里手动添加的声音）

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savering功能将使用传递的参数知道哪些文件进行保存。 （这正好在那里你以前称为函数）

savering(soundArray[ressound]);
