按钮声音问题

当我启动我的应用程序时，出现主菜单，当我点击2个按钮中的任何一个时，它会使按钮发声，然后转到指定的布局。我遇到的问题是，如果我从布局返回到主屏幕并尝试再次按下按钮，它仍然会将我带到布局，但不会使按钮响起。有任何想法吗？谢谢您的帮助。按钮声音问题

     }); 
     ImageButton settingsbutton = (ImageButton) findViewById(R.id.settingsbutton); 
     settingsbutton.setOnClickListener(new View.OnClickListener() {

编辑：试试这个：

if(buttonSound.isPlaying()) { 
    buttonSound.stop(); 
} 

try { 
    buttonSound.prepare(); 
} catch (IllegalStateException e) { 
    e.printStackTrace(); 
} catch (IOException e) { 
    e.printStackTrace(); 
} 

buttonSound.start();

（check out Google MediaPlayer state diagram）

好吧，似乎几分钟的工作，但现在它回到它开始。我把我的新代码。它看起来不错吗？ – Zach

你可以在按下按钮时将你在LogCat中获得的东西放到哪里？我的图像有一个堆栈跟踪，每当声音不播放时就会发生。 – mopsled

我把它放在上面。 – Zach
