Android 按钮声音有问题

android eclipse

Android 按钮声音有问题,android,eclipse,Android,Eclipse,当我启动我的应用程序时，主菜单会出现，当我点击两个按钮中的任何一个时，按钮会发出声音，然后进入指定的布局。我遇到的问题是，如果我从布局返回到主屏幕，并尝试再次点击按钮，它仍然会将我带到布局，但不会使按钮发出声音。有什么想法吗？谢谢你的帮助 DragonFutureActivity.java package com.Dragon_Fruit; import android.app.Activity; import android.content.Intent; import android.me

编辑：尝试以下操作：

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

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

buttonSound.start();

好吧，这似乎在几分钟内奏效，但现在又回到了起点。我把我的新密码放上去了。它看起来对吗？当你按下按钮时，你能把你得到的东西放进LogCat吗？我想象每当声音不播放时就会出现堆栈跟踪。我编辑了代码来处理已经播放的声音。再试一次。这也很有效，但我刚刚想出了一些办法。当我认为它没有发出声音时，实际上是这样。真的很安静。如果我听清楚了，我就能听到。你可以尝试一下MediaPlayer的方法，但是你可能想开始一个新的问题，因为这个问题与原来的问题大不相同。
