单击按钮启动AlarmManager

Question

I want to start an AlarManager when a button is pressed. The problem is: The AM starts when I start the app :/

My Code:

public void scheduleAlarm()
    {  
            int time = 10 * 1000;

            intentAlarm = new Intent(this, AlarmReciever.class);

            alarm = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
            alarm.setRepeating(AlarmManager.RTC_WAKEUP, time, time, PendingIntent.getBroadcast(this,1,  intentAlarm, PendingIntent.FLAG_UPDATE_CURRENT));

    }

And I try to call this in a onClickListener of a button. But it starts from beginning of activity :/

Can anyone help me?

Answer 1

thanks for posting your code. Try this:

public static String ALARM_TO_SET = "ALRMTOSEND";
yourButton.setOnClickListener(new OnClickListener(){
public void onClick(View view){
     int time = 10 * 1000;

    intentAlarm = new Intent(ALARM_TO_SET);

    alarm = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
    PendingIntent pIntent = PendingIntent.getBroadcast(this, 0, intentAlarm, 0)
    alarm.setRepeating(AlarmManager.RTC_WAKEUP, time, time, pIntent);


  }
});

Your Broadcast receiver should be registered in the Manifest.xml file as:

<receiver android:name=".AlarmRecieverClass">
<intent-filter>
<action android:name="ALRMTOSEND" />
</intent-filter>
</receiver>

你应该移动setRepeating电话里面onClickListener方法

为什么不为此使用timerTask。

Try this:

Button yourButton = (Button)findViewById(R.id.yourId);
yourButton.setOnClickListener(new OnClickListener(){
   public void onClick(View view){
         int time = 10 * 1000;

        intentAlarm = new Intent(this, AlarmReciever.class);

        alarm = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
        alarm.setRepeating(AlarmManager.RTC_WAKEUP, time, time, PendingIntent.getBroadcast(this,1,  intentAlarm, PendingIntent.FLAG_UPDATE_CURRENT));


   }
  });
