【中文标题】如何在android中停止闹钟【英文标题】:How to stop an alarm in android 【发布时间】:2013-07-11 01:25:36 【问题描述】:

在我的主要活动中,其中有一个按钮。在其 onclick 侦听器中,我正在调用函数来设置警报。警报正在工作,但我无法停止它。有人可以帮我吗

MainActivity.java

public class MainActivity extends Activity 

    @Override
    protected void onCreate(Bundle savedInstanceState) 
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        findViewById(R.id.button1).setOnClickListener(new OnClickListener() 
            @Override
            public void onClick(View v) 
                setalarm();
            


        );
    

    private void setalarm() 

        Calendar cal=Calendar.getInstance();
        // cal.set(Calendar.MONTH,6);
        // cal.set(Calendar.YEAR,2013);
        // cal.set(Calendar.DAY_OF_MONTH,12);
        cal.set(Calendar.HOUR_OF_DAY,18);
        cal.set(Calendar.MINUTE,32);
        Intent intent = new Intent(this, Mote.class);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(this.getApplicationContext(), 1253, intent, PendingIntent.FLAG_UPDATE_CURRENT|  Intent.FILL_IN_DATA);

        AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);

        alarmManager.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),pendingIntent );
        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);
        Toast.makeText(this, "Alarm SET.", Toast.LENGTH_LONG).show();
    

    @Override
    public boolean onCreateOptionsMenu(Menu menu) 
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    

Mote.java:

public class Mote  extends BroadcastReceiver

    public void onReceive(Context context, Intent intent) 
        Toast.makeText(context, "Alarm worked.", Toast.LENGTH_LONG).show();
        int icon = R.drawable.ic_launcher;
        CharSequence tickerText = "Hello you have to take medicine I am Nitin Sharma";
        long when = System.currentTimeMillis();

        CharSequence contentTitle = "My notification";
        CharSequence contentText = "Hello World!";

        final int NOTIF_ID = 1234;
        NotificationManager notofManager = (NotificationManager)context. getSystemService(Context.NOTIFICATION_SERVICE);
        Intent notificationIntent = new Intent(context, Alset.class);
        PendingIntent contentIntent = PendingIntent.getActivity(context,0, notificationIntent, 0);
        Notification notification = new Notification(icon, tickerText,when );
        notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
        notification.flags = Notification.FLAG_INSISTENT;
        notification.defaults |= Notification.DEFAULT_SOUND;
        notofManager.notify(NOTIF_ID,notification);

        Toast.makeText(context, "Alarm worked.", Toast.LENGTH_LONG).show();

        Intent i = new Intent(context,Alset.class);
        i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(i);

Alset.java:

public class Alset extends Activity

    @Override
    protected void onCreate(Bundle savedInstanceState) 
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activitystop); 
        Log.e("IM here ","Im here");

        findViewById(R.id.button1).setOnClickListener(new OnClickListener() 

            @Override
            public void onClick(View v) 
                Toast.makeText(Alset.this, "Stop the alrm now", Toast.LENGTH_LONG).show();
            
        );
       

一旦警报开始,我将在接收者的OnReceive() 方法中获得回调。从那里我要去活动 Alset,在那里我保留了一个停止按钮。如何从这里停止闹钟?

注意:- 我正在硬编码设置闹钟的时间。

【问题讨论】:

您需要从报警管理器中取消报警尝试==== AlarmManager alarmManager = (AlarmManager) _cntx.getSystemService(Context.ALARM_SERVICE); PendingIntent pendingIntent = PendingIntent.getBroadcast(this.getApplicationContext(), 1253, 意图, PendingIntent.FLAG_UPDATE_CURRENT| Intent.FILL_IN_DATA); alarmManager.cancel(pendingIntent); 【参考方案1】:

你可以这样取消闹钟:

     Intent intent = new Intent(this, Mote.class);
     PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(), 1253, intent, 0);
     AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
     alarmManager.cancel(pendingIntent);

此外,您应该在设置闹钟的代码中从对getBroadcast() 的调用中删除Intent.FILL_IN_DATA

@droid_dev 如果您遇到问题,请打开一个新问题并发布您的代码并解释什么不起作用。社区可以帮助您。 alarmManager.cancel(pendingIntent) 只会取消来自alarmManager的警报。它不会杀死被解雇的活动。我还提出了知道如何杀死被解雇的活动的问题。参考***.com/questions/29735209/…如果有人知道答案请回复 我最初的意图添加了一个动作,所以为了让它工作,我添加了相同的动作到意图中。 @Favolas 是的,当然。您需要创建一个匹配的Intent,因此 ACTION、CATEGORY、DATA 和 COMPONENT 信息必须全部匹配。 @DavidWasser 嘿伙计,你能帮我解决我 2-3 天以来一直遇到的问题吗,这是我的问题***.com/questions/43950978/…【参考方案2】:

你需要从警报管理器取消警报试试这个,

Intent intent = new Intent(this, Mote.class);
AlarmManager alarmManager = (AlarmManager) _cntx.getSystemService(Context.ALARM_SERVICE);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this.getApplicationContext(), 1253, intent, PendingIntent.FLAG_UPDATE_CURRENT|  Intent.FILL_IN_DATA);          
alarmManager.cancel(pendingIntent);
