我已经创建了一个从主活动调用的服务,并传递一个简单的变量来访问服务内部并向屏幕干杯.我似乎无法找到从服务内部访问变量的正确代码.任何帮助将不胜感激.谢谢.

从按钮单击侦听器内部调用服务的主Activity:

@Override
public void onClick(View v) {

    Intent eSendIntent = new Intent(getApplicationContext(), eSendService.class);

    eSendIntent.putExtra("extraData", "somedata");

    startService(eSendIntent);

}

eSendService服务类代码:

public class eSendService extends Service {


    @Override
    public IBinder onBind(Intent intent) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public void onCreate() {
        // TODO Auto-generated method stub
        super.onCreate();

            // This is the code that I am struggling with.  Not sure how to access the
            // variable that was set in the intent.  Please advise.
            // The below code …

我在Drupal 7中有一个查询正在搜索自定义表:

$query5 = "SELECT COUNT(reservation_id) as rcount5, reservation_id FROM {reservations} WHERE resource_id = :resource_id AND reservation_date = :reservation_date AND start_time BETWEEN :start_time AND :end_time";
$result5 = db_query($query5, array(':resource_id' => $resource_id, ':reservation_date' => $reservation_date, ':start_time' => $start_time, ':end_time' => $end_time));

查询无效,因为我认为它没有正确识别BETWEEN函数并返回end_time,因为它存在.有没有办法显示drupal或db api这是BETWEEN语句？谢谢.
