Android 即使我按下停止按钮，闹钟也会一直响

我做了一个闹钟，它几乎正常工作，只是它从不停止。 即使我按下了“停止”按钮，闹钟也会一直响

我有两个按钮，一个id为setthealarm，另一个id为stopthealarm

在公共类

main活动中

I定义

TimePicker

、

pendingent

和

AlarmManager

public class activity_mainnew extends Activity {
TimePicker alarmTimePicker;
    PendingIntent pendingIntent;
    AlarmManager alarmManager;



@SuppressLint("NewApi")
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_mainnew);
alarmTimePicker = (TimePicker) findViewById(R.id.timePicker);
alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
}

单击一次设置时间

：

@RequiresApi(api = Build.VERSION_CODES.M)
    public void setthealarm(View view){
        Toast.makeText(activity_mainnew.this, "ALARM ON", Toast.LENGTH_SHORT).show();
        long time;

        Calendar calendar = Calendar.getInstance();
        calendar.set(Calendar.HOUR_OF_DAY, alarmTimePicker.getHour());
        calendar.set(Calendar.MINUTE, alarmTimePicker.getMinute());

        Intent intent = new Intent(this, AlarmReceiver.class);
        pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);

        alarmTimePicker.setDescendantFocusability(TimePicker.FOCUS_BLOCK_DESCENDANTS);

        time = (calendar.getTimeInMillis()-(calendar.getTimeInMillis()%60000));
        if(System.currentTimeMillis()>time)
        {
            if (calendar.AM_PM == 0)
                time = time + (1000*60*60*12);
            else
                time = time + (1000*60*60*24);
        }
        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, time, 10000, pendingIntent);
    }

@RequiresApi(api = Build.VERSION_CODES.M)
public void stopthealarm(View view){
    Toast.makeText(activity_mainnew.this, "ALARM OFF", Toast.LENGTH_SHORT).show();
    Intent intent = new Intent(this, AlarmReceiver.class);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);
    AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
    alarmManager.cancel(pendingIntent);
    pendingIntent.cancel();
}

并在单击时停止报警
：

@RequiresApi(api = Build.VERSION_CODES.M)
    public void setthealarm(View view){
        Toast.makeText(activity_mainnew.this, "ALARM ON", Toast.LENGTH_SHORT).show();
        long time;

        Calendar calendar = Calendar.getInstance();
        calendar.set(Calendar.HOUR_OF_DAY, alarmTimePicker.getHour());
        calendar.set(Calendar.MINUTE, alarmTimePicker.getMinute());

        Intent intent = new Intent(this, AlarmReceiver.class);
        pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);

        alarmTimePicker.setDescendantFocusability(TimePicker.FOCUS_BLOCK_DESCENDANTS);

        time = (calendar.getTimeInMillis()-(calendar.getTimeInMillis()%60000));
        if(System.currentTimeMillis()>time)
        {
            if (calendar.AM_PM == 0)
                time = time + (1000*60*60*12);
            else
                time = time + (1000*60*60*24);
        }
        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, time, 10000, pendingIntent);
    }

@RequiresApi(api = Build.VERSION_CODES.M)
public void stopthealarm(View view){
    Toast.makeText(activity_mainnew.this, "ALARM OFF", Toast.LENGTH_SHORT).show();
    Intent intent = new Intent(this, AlarmReceiver.class);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);
    AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
    alarmManager.cancel(pendingIntent);
    pendingIntent.cancel();
}

在AlarmReceiver类中，我有以下内容：

public class AlarmReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Uri alarmUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM);

        if (alarmUri == null) {
        alarmUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        }

        Ringtone ringtone = RingtoneManager.getRingtone(context, alarmUri);
        ringtone.play();
    }
}

你知道为什么铃声没有停止吗？
这可能是因为你没有在这个问题中粘贴代码，但我实际上没有看到将stopthealarm连接到单击按钮的代码。您确定stopthealarm函数会触发吗

你这样做是为了setthealarm，但不是为了stopthealarm

善意的问候

要正确取消您的报警，您需要让挂起的帐篷使用
标志\u UPDATE\u CURRENT
标志

PendingIntent pendingIntent = PendingIntent.getBroadcast(this, AlarmReceiver.REQUEST_CODE, intent, PendingIntent.FLAG_UPDATE_CURRENT);

在AlarmReceiver类的开头，在
onReceive（）
之前添加请求代码行：

要在单击停止按钮时停止铃声上的铃声
stop（）
：

Ringtone ringtone = RingtoneManager.getRingtone(context, alarmUri);
ringtone.stop();

我忘记写了。。按钮功能正在工作，但他们忘了写。。按钮功能在两个方面都起作用。您是否尝试过
ringtone.stop（）何时停止？您是否尝试过
铃声.stop（）
