我有一个程序，允许用户输入 3 次警报，然后在适当的时间显示警报。但是，每当我设置警报时，只会执行最后一个警报。
所以基本上，用户输入 1,2 或 3 然后我执行时间选择对话框的数量，然后将这些时间发送到警报接收器。但只有最后一个警报正在执行。任何帮助表示赞赏。为代码长度道歉，我知道这非常低效。

和广播接收器活动：
public class AlarmReceiver extends BroadcastReceiver {

public void onReceive(Context arg0, Intent arg1) {

Toast toast;

toast.setGravity(Gravity.CENTER, 0,0);
toast.show();
Vibrator vibrator = (Vibrator) arg0.getSystemService(Context.VIBRATOR_SERVICE);
vibrator.vibrate(1000);
}
public void playSound(){
ToneGenerator alertTone = new ToneGenerator(AudioManager.STREAM_DTMF,ToneGenerator.MAX_VOLUME);
alertTone.startTone(ToneGenerator.TONE_DTMF_1, 1000);
}
}
