我在日曆中插入了一個事件。創建事件的時間也必須在同一時間響起的警報創建。怎麼做?我使用了下面的代碼,它給出了錯誤。 主要活動:如何在創建日曆事件時創建鬧鐘?
Calendar caln = Calendar.getInstance();
caln.add(Calendar.SECOND, 2);
Intent intent = new Intent(ToDoApplicationActivity.this, AlarmReceiver.class);
intent.putExtra("alarm_message", title1);
PendingIntent sender = PendingIntent.getBroadcast(this, 192837, intent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), sender);
startActivity(intent);
的onReceive方法overrided:
public void onReceive(Context context, Intent intent) {
try {
Bundle bundle = intent.getExtras();
String message = bundle.getString("alarm_message");
Intent newIntent = new Intent(context, ToDoApplicationActivity.class);
newIntent.putExtra("alarm_message", message);
newIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(newIntent);
} catch (Exception e) {
Toast.makeText(context, "There was an error somewhere, but we still received an alarm", Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
}
錯誤了:
android.content
當我使用下面的代碼我得到以下錯誤。 ActivityNotFoundException:無法找到顯式活動類{com.android.todoapplication/android.todoapplica tion.AlarmReceiver};你有沒有在你的AndroidManifest.xml中聲明這個活動?
任何幫助,高度讚賞,並在此先感謝...
