尝试在特定时间创建通知

我删除了日历属性，它在我运行应用程序后直接运行但是当我尝试使用日历设置特定时间时，我在设置它时不起作用

MainActivity

import android.support.v7.app.ActionBarActivity;
 import android.os.Bundle;
 import android.view.Menu;
 import android.view.MenuItem;
  import android.app.*;
  import android.*;
   import android.support.v4.app.NotificationCompat;
   import android.content.*;
  import android.view.View;
  import android.widget.Button;

  import java.util.Calendar;

 import static android.app.PendingIntent.FLAG_CANCEL_CURRENT;


 public class MainActivity extends ActionBarActivity {
  private PendingIntent pendingIntent;

@Override
  public void onCreate(Bundle savedInstanceState)
{

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Calendar calendar = Calendar.getInstance();



    calendar.set(Calendar.HOUR_OF_DAY, 13);
    calendar.set(Calendar.MINUTE, 48);
    calendar.set(Calendar.SECOND, 00);
    calendar.set(Calendar.AM_PM,Calendar.PM);

    Intent myIntent = new Intent(MainActivity.this, MyReceiver.class);
    pendingIntent = PendingIntent.getBroadcast(MainActivity.this, 0,                      
     myIntent,0); 
    AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
    alarmManager.set(AlarmManager.RTC, calendar.getTimeInMillis(),     pendingIntent);

} //end onCreate



}

MyReceiver

  import android.content.BroadcastReceiver;
  import android.content.Context;
  import android.content.Intent;
  public class MyReceiver extends BroadcastReceiver {
   @Override
  public void onReceive(Context context, Intent intent) {
    Intent service1 = new Intent(context, MyAlarmService.class);
    context.startService(service1);

}

}

MyAlarmService

mport android.app.Service;
import android.content.Intent;
 import android.os.IBinder;
  import android.app.*;

 /**
   * Created by osamaalammari on 4/10/15.
  */
 public class MyAlarmService extends Service {
private NotificationManager mManager;

@Override
public IBinder onBind(Intent intent) {
    return null;
}

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

@SuppressWarnings("static-access")
@Override
public void onStart(Intent intent, int startId)
{
    super.onStart(intent, startId);

    mManager = (NotificationManager) 
                     this.getApplicationContext().getSystemService(this.getApplicationContext().   

    NOTIFICATION_SERVICE);
    Intent intent1 = new     
     Intent(this.getApplicationContext(),MainActivity.class);

    Notification notification = new 
      Notification(R.drawable.ic_launcher,"This is a test message!",  
      System.currentTimeMillis());
    intent1.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP|    
     Intent.FLAG_ACTIVITY_CLEAR_TOP);
           PendingIntent pendingNotificationIntent =    
        PendingIntent.getActivity( this.getApplicationContext(),0,  
        intent1,PendingIntent.FLAG_UPDATE_CURRENT);


    notification.flags |= Notification.FLAG_AUTO_CANCEL;
    notification.setLatestEventInfo(this.getApplicationContext(),  
       "AlarmManagerDemo", "This is a test message!",    
    pendingNotificationIntent);

    mManager.notify(0, notification);
}

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


  }

尝试这样的事情。

public class MyAlarmService extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        CreateNotification(context, "Forgetting something?", "Click here for more details", "Alert");
    }

    private void CreateNotification(Context context, String title, String text, String alert) {
        PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, new Intent(context, MainActivity.class), 0);

        NotificationCompat.Builder notification = new NotificationCompat.Builder(context)
                .setTicker(alert)
                .setSmallIcon(R.drawable.ic_launcher)
                .setContentTitle(title)
                .setContentText(text)
                .setDefaults(Notification.DEFAULT_SOUND)
                .setAutoCancel(true);

                notification.setContentIntent(pendingIntent);

        NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(1, notification.build());

    }
}

请记住在清单中添加这样的内容：

<receiver
            android:name="yourpackagename.MyAlarmService">
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED"/>
            </intent-filter>
        </receiver>

然后在您希望发出通知的班级中：

notificationTime = calendar.getTimeInMillis();

Intent intent = new Intent(getActivity(), MyAlarmService.class);
            AlarmManager alarmManager = (AlarmManager) getActivity().getSystemService(Context.ALARM_SERVICE);
            alarmManager.set(AlarmManager.RTC_WAKEUP, notificationTime, PendingIntent.getBroadcast(getActivity()
                    .getApplicationContext(), 1, intent, PendingIntent.FLAG_UPDATE_CURRENT));
            Toast.makeText(getActivity(), "Notification sent!" ,Toast.LENGTH_SHORT).show();
