I know, there are tons of these on here, but I ve been trying solutions all day and haven t gotten anywhere. Neither the example on google s docs, nor any of the 5 other ways I ve found on here have worked for me at all. As is the typical case, when I click the notification it closes the status bar and nothing new is shown onscreen. I am creating the notification from a service and need the notification to trigger a new activity that has not yet been created. I also will need a way to pass information to that activity via intent.

And yes... this is java for Android

以下是我法典的破碎残余物。

import android.app.Notification;
import android.app.NotificationManager;

import android.provider.ContactsContract;
import android.widget.Toast;

public class contactBackup extends Service
{
    private NotificationManager nManager;
    private static final int NOTIFY_ID = 1100;

    @Override
    public void onCreate()
    {
        super.onCreate();

        String ns = Context.NOTIFICATION_SERVICE;
        nManager = (NotificationManager)getSystemService(ns);
    }

    @Override
    public void onStart(Intent intent, int startId) {
        super.onStart(intent, startId);

        // inform user that service has started
        Toast.makeText(getApplicationContext(), R.string.service_started,Toast.LENGTH_LONG).show();

        String data = lookUpContacts();
        if( saveToSDCard(getResources().getString(R.string.backup_file_name),data) )
        {
            Context context = getApplicationContext();

            // create the statusbar notification
            Intent nIntent = new Intent(this,contactViewer.class);//Intent nIntent = new Intent(Intent.ACTION_MAIN);
            nIntent.setClass(context,contactViewer.class);
            //nIntent.putExtra("data",data);


            Notification msg = new Notification(R.drawable.icon,"All contacts records have been written to the file.",System.currentTimeMillis());
            // start notification
            //PendingIntent pIntent = PendingIntent.getService(getApplicationContext(),0,nIntent,PendingIntent.FLAG_UPDATE_CURRENT|Intent.FLAG_FROM_BACKGROUND);
            PendingIntent pIntent = PendingIntent.getActivity(this,0,nIntent,0);
            msg.flags = Notification.FLAG_AUTO_CANCEL;
            msg.setLatestEventInfo(context,
                                   "success",
                                   "All contacts records have been written to the file.",
                                   pIntent);
            nManager.notify(NOTIFY_ID,msg);


        }



    }

    @Override
    public void onDestroy()
    {
        nManager.cancel(NOTIFY_ID);
        super.onDestroy();
    }

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

    // function returns string containing information
    // from contacts
    public String lookUpContacts()
    {
        ...
    }

    public boolean saveToSDCard(String fileName, String data)
    {
        ...
    }

}

我只能希望,造成我问题的任何事情都是可以解决的,而不是我所 的摇篮(似乎没有人看到过这种lip;U)
