当您设置正在进行广播的AlarmManager.RTC_WAKEUP时，您需要一个广播接收器，在接收时启动报警活动
例如，当您按下设置警报按钮
public void onClick(View v) {
Intent intent = new Intent(getBaseContext(), AlarmBroadcastReciever.class);
intent.putExtra("message", "alarm 1 starts");
PendingIntent alarmIntent = PendingIntent.getBroadcast(getBaseContext(), 0, intent, 0);
long startTime = ...
AlarmManager alm = (AlarmManager) getSystemService(ALARM_SERVICE);
alm.set(AlarmManager.RTC_WAKEUP, startTime, alarmIntent);
Toast.makeText(.....Toast.LENGTH_LONG).show();
}
};
现在你需要AlarmBroadcastReciever
public class AlarmBroadcastReciever extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
String msg = intent.getStringExtra("message");
Toast.makeText(context, msg, Toast.LENGTH_SHORT).show();
Intent alarmPage = new Intent(context, Alarm.class);
alarmPage.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(alarmPage);
}
}
