我有一个程序允许用户输入三次警报，然后在适当的时候显示警报。但是，每当我设置警报时，只执行最后一次警报。
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。但只有最后一次警报正在进行中。任何帮助表示赞赏。对代码长度表示道歉，我知道它效率非常低。

广播接收器活动：
public class AlarmReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context arg0, Intent arg1) {
playSound();
Toast toast;
toast = Toast.makeText(arg0, "Time for Blood Glucose Testing!", Toast.LENGTH_LONG);
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);
}
}
答案 0 :(得分：0)
req，req2和req3的值是多少？每个警报需要有所不同。
此外，我认为这不会解决您的问题，但您不需要调用set（）＆amp;在AlarmManager上设置setRepeating（），只是其中一个。
调用set（）并在发生警报时自行重置警报，或让AlarmManager使用setRepeating（）处理重置。
