在我的主要活动中有一个按钮.在其onclick监听器调用功能设置闹钟.闹钟正在工作,但我无法阻止它.可以帮助一个人
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,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,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,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();
}
});
}
}
}
}
一旦报警开始,我将在接收机的OnReceive()中收到回叫,从那里我进入活动Alset,我保持停止按钮.如何阻止这里的闹钟
注意： – 我可以硬编码设置闹钟的时间
解决方法
您可以这样取消警报：
Intent intent = new Intent(this,Mote.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(),0);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.cancel(pendingIntent);
