我发现这个很多类似的问题，但他们太复杂（太多的代码），至少我这样认为。
可这件事情中的行数代码来完成？ 我想火在10活动（比方说）分钟，仅此而已。 谢谢。
Answer 1:
本博客文章介绍正是你所期待的。
Answer 2:
到10分钟，设置闹钟（比方说）使用此代码
AlarmManager alarmMgr = (AlarmManager)getSystemService(ALARM_SERVICE);
Intent intent = new Intent(this, ShortTimeEntryReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(),10*60*1000, pendingIntent);
要启动活动
public class ShortTimeEntryReceiver extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent) {
try {
Bundle bundle = intent.getExtras();
String message = bundle.getString("alarm_message");
// Your activity name
Intent newIntent = new Intent(context, ReminderPopupMessage.class);
newIntent.putExtra("alarm_message", message);
newIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(newIntent);
} catch (Exception e) {
e.printStackTrace();
}
}
}
在您的清单文件中添加以下
<receiver android:name=".ShortTimeEntryReceiver"
android:enabled="true"
android:process=":remote">
</receiver>
Answer 3:
这个功能我用的设定或取消根据“设置”参数报警
public static void SetAlarm(Context c, long AlarmTime, int ItemID, String Message, Boolean Set) {
Intent intent = new Intent(c, AlarmReceiver.class);
intent.putExtra("Message", Message);
intent.putExtra("ItemID", ItemID);
PendingIntent sender = PendingIntent.getBroadcast(c, 8192 + ItemID, intent, PendingIntent.FLAG_UPDATE_CURRENT);
// Clear the seconds to 0 for neatness
Calendar ca = Calendar.getInstance();
ca.setTimeInMillis(AlarmTime);
ca.set(Calendar.SECOND, 0);
AlarmTime = ca.getTimeInMillis();
// Get the AlarmManager service
AlarmManager am = (AlarmManager) c.getSystemService(Context.ALARM_SERVICE);
if (Set) {
am.set(AlarmManager.RTC_WAKEUP, AlarmTime, sender);
} else {
am.cancel(sender);
}
}
那么你就需要一个广播接收器来处理报警，做什么是你想做的事情。
public class AlarmReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
try {
Bundle bundle = intent.getExtras();
String Message = bundle.getString("Message");
int ItemID = bundle.getInt("ItemID");
// Do what you want to do, start an activity etc
} catch (Exception e) {
e.printStackTrace();
}
}
}
