Eclipse：Android Soundboard按钮可以“过度点击”

Question

在我的android音板中，所有按钮都可以正常工作，声音可以正常播放，但存在问题。问题是，当你按下应用程序中的按钮时，你可以按其他按钮。例如，如果我按下的按钮播放噪音声，我可以按另一个按钮，同时播放两个声音。这不是我想要的。有没有我可以添加的代码，以便我可以一次只点击一个按钮，或者一些代码可以让以前的声音停止，并且它会播放新选择的声音？

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.soundboard" 
    android:versionCode="1" 
    android:versionName="1.2"> 
<application android:icon="@drawable/icon" android:label="@string/app_name" android:debuggable="false" android:allowClearUserData="true"> 
    <activity android:label="Vegeta Soundboard" android:screenOrientation="portrait" android:name="Soundboard" android:icon="@drawable/icon"> 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 
      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity> 


</application> 

<uses-sdk android:minSdkVersion="3" />

最简单的事情是只是有一个soundPlaying布尔值，是全球性的，你当用户点击一个按钮的声音，这是由声中结束未设置设置。

public class Main extends Activity{ 




    //global variable, notice how it's not in any method or inner class 
    //so it's accessible to all the members of this class 
    private boolean soundPlaying = false; 




    @Override 
     public void onCreate(Bundle b){ 
      super.onCreate(b); 
     } 


    //Somewhere in here you have your onclick function that you have called from your xml button 
    public void playSound(View v){ 
    if(soundPlaying) 
     return; 
    soundPlaying = true; 
//myMedia is your media player object 

    myMedia.start();//this will only work if you have a media player set up with media 

    myMedia.setOnCompletionListener(new OnCompletionListener() {    
      @Override 
      public void onCompletion(MediaPlayer mp) { 
       soundPlaying = false;//here you set it to false cause the sound is done 

      } 
     }); 
    } 





    }
