修改 的
好的，我发现如果我在尝试保存之前播放任何声音，当你试图保存它们时它会正常工作?????
修改 的
我有一个声音板，我已经制作了一个小问题，我将声音保存到手机的SDCARD，在Android 2.2安卓平板电脑上工作正常。
但是当我在使用Android 2.3的手机上运行并尝试保存声音时，我会收到强制关闭错误？

不确定是否与我保存声音的位置有关，如果这对于不同版本而言是不同的？也许这一行？

答案 0 :(得分：1)
savering(selectedSoundId)
似乎“selectedSoundId”可能未初始化
为了使您的selectedSoundId成为有效值，您需要单击声音并播放它。那部分会发生吗？
否则，你必须在function1（和2）方法中使用与clickListener中相同的代码，以便为menuId找到合适的soundId。
