Answer 1

使用以下步骤。

日历提醒：

1.创建一个事件：

// get calendar
Calendar cal = Calendar.getInstance();     
Uri EVENTS_URI = Uri.parse(getCalendarUriBase(this) + "events");
ContentResolver cr = getContentResolver();

// event insert
ContentValues values = new ContentValues();
values.put("calendar_id", 1);
values.put("title", "Reminder Title");
values.put("allDay", 0);
values.put("dtstart", cal.getTimeInMillis() + 11*60*1000); // event starts at 11     minutes from now
values.put("dtend", cal.getTimeInMillis()+60*60*1000); // ends 60 minutes from now
values.put("description", "Reminder description");
values.put("visibility", 0);
values.put("hasAlarm", 1);
Uri event = cr.insert(EVENTS_URI, values);

2.然后创建提醒并将其设置为：

// reminder insert
Uri REMINDERS_URI = Uri.parse(getCalendarUriBase(this) + "reminders");
values = new ContentValues();
values.put( "event_id", Long.parseLong(event.getLastPathSegment()));
values.put( "method", 1 );
values.put( "minutes", 10 );
cr.insert( REMINDERS_URI, values );

3.将权限设置为：

<uses-permission android:name="android.permission.READ_CALENDAR" />
<uses-permission android:name="android.permission.WRITE_CALENDAR" />

仅限闹钟：

1.创建广播接收器：

public class AlarmReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        try {
            Bundle bundle = intent.getExtras();
            String message = bundle.getString("alarm_message");
            Toast.makeText(context, message, Toast.LENGTH_SHORT).show();
        } catch (Exception e) {
            Toast.makeText(context, "There was an error somewhere, but we still received an alarm", Toast.LENGTH_SHORT).show();
            e.printStackTrace();
        }
    }
}

2.设置权限：

<receiver  android:process=":remote" android:name="AlarmReceiver"></receiver>

3.设置活动：

// get a Calendar object with current time
Calendar cal = Calendar.getInstance();
// add 5 minutes to the calendar object
cal.add(Calendar.MINUTE, 5);
Intent intent = new Intent(ctx, AlarmReceiver.class);
intent.putExtra("alarm_message", "O'Doyle Rules!");
// In reality, you would want to have a static variable for the request code instead of 192837
PendingIntent sender = PendingIntent.getBroadcast(this, 192837, intent,    PendingIntent.FLAG_UPDATE_CURRENT);

// Get the AlarmManager service
AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), sender);

4.广播接收机的活动：

@Override
public void onReceive(Context context, Intent intent) {
    try {
        Bundle bundle = intent.getExtras();
        String message = bundle.getString("alarm_message");

        Intent newIntent = new Intent(context, AlarmActivity.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();
    }
}

根据需要修改代码。
