安卓闹钟设置多个,只有第一个设置的闹钟能正确进行闹铃提醒

毕业设计做的是基于安卓平台的备忘录闹钟,整个程序可以运行,但是闹钟可以新建多个,只有第一个设置的闹钟可以
正确进行提醒,后面的闹钟事件一到时间整个程序就会出错,求大神帮忙,本来对安卓知识就知道甚少,也不会进行错误调试,希望能有大神来帮我看一下,谢谢了。
这是闹钟事件触发时弹出的提醒对话框的java方法:
public class AlertDialogActivity extends Activity implements OnClickListener{

public static AlertDialogActivity context = null;
private MediaPlayer player = new MediaPlayer();
WakeLock mWakelock;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);
    getWindow().addFlags(
            WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
                            | WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);
    getWindow().addFlags(
            WindowManager.LayoutParams.FLAG_ALLOW_LOCK_WHILE_SCREEN_ON
                            | WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON); //在锁屏时仍能启动闹钟
    context = this;
    try{
        Uri localUri = RingtoneManager.getActualDefaultRingtoneUri(context, RingtoneManager.TYPE_ALARM);
        if((player != null) && (localUri != null))
        {
                player.setDataSource(context,localUri);
                player.prepare();
                player.setLooping(false);
                player.start();
        }

        AlertDialog.Builder localBuilder = new AlertDialog.Builder(context);
        localBuilder.setTitle(R.string.alertName);
        localBuilder.setMessage("看看该做什么了");
        localBuilder.setPositiveButton(R.string.positiveButton,this);
        localBuilder.setNegativeButton(R.string.negativeButton,this);
        localBuilder.show();

    }catch (IllegalArgumentException localIllegalArgumentException)
    {
          localIllegalArgumentException.printStackTrace();
        }
        catch (SecurityException localSecurityException)
        {
          localSecurityException.printStackTrace();
        }
        catch (IllegalStateException localIllegalStateException)
        {
          localIllegalStateException.printStackTrace();
        } catch (IOException e) 
        {
            e.printStackTrace();
        }
    }
@Override
public void onClick(DialogInterface dialog, int which) {
    // TODO Auto-generated method stub
    switch(which){
    case DialogInterface.BUTTON1:
    {
        Intent intent = new Intent(AlertDialogActivity.this, EditActivity.class);
        Bundle b = new Bundle();
        b.putString("datetime",getIntent().getStringExtra("datetime"));
        b.putString("content", getIntent().getStringExtra("content"));
        b.putString("alerttime",getIntent().getStringExtra("alerttime"));
        intent.putExtra("android.intent.extra.INTENT", b);
        startActivity(intent);                                //启动转到的Activity
        finish();
    }
    case DialogInterface.BUTTON2:
    {

// mWakelock.release();
player.stop();
finish();
}
}
}
}
