android - 当我从 GCM 服务器收到通知时如何更新操作栏上的通知图标

Question

当我从服务器收到通知时如何更新通知图标？这是我从服务器获取通知的代码。

 public class GCMMessageHandler extends GCMBaseIntentService {
    static int notificationcount;
    TAB_Activity tab_Activity;
    int count= 0;
    public GCMMessageHandler() {
        super("GCMMessageHandler");
        // TODO Auto-generated constructor stub
    }
    String message,ticketno,name,status,problem;
    private Handler handler;
    @Override
    protected void onError(Context arg0, String arg1) {
        // TODO Auto-generated method stub

    }



    @Override
    protected void onMessage(Context context, Intent intent) {
        // TODO Auto-generated method stub

        Bundle extras = intent.getExtras();

        GoogleCloudMessaging gcm = new GoogleCloudMessaging().getInstance(this);
        String messagetype= gcm.getMessageType(intent);
        count++;
        System.out.println(extras);
        message = extras.getString("message");
        ticketno= extras.getString("ticket_no");
        problem=extras.getString("problem_desc");
        name= extras.getString("name");
        status= extras.getString("t_status");
        Log.i("GCM   Messge Recieved"," (" +messagetype+")  "+extras.getString("message"));
        GCMintentService.completeWakefulIntent(intent);
        Intent in = new Intent(this, Chat_activity.class);
        // Pass data to the new activity
        Bundle bd = new Bundle();
        bd.putString("TicketID", ticketno);
        bd.putString("problem", problem);
        in.putExtras(bd);

        in.setData(Uri.parse("tel:/"+(int)System.currentTimeMillis()));

        // Starts the activity on notification click
        PendingIntent pIntent = PendingIntent.getActivity(this, 0, in,
        Intent.FLAG_ACTIVITY_NEW_TASK);
        // Create the notification with a notification builder
        NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(context)
        .setWhen(System.currentTimeMillis())
        .setContentText(message+" :-"+name)
        .setContentTitle(ticketno)
        .setSmallIcon(R.drawable.assignedtickets)
        .setTicker("Smart CRM")
        .setContentIntent(pIntent)
        .setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION));


Notification notification = notificationBuilder.build();

    manager.notify((int)System.currentTimeMillis(), notification);

    ActivityManager  activityManager = (ActivityManager)context.getSystemService(ACTIVITY_SERVICE);
    List<RunningAppProcessInfo> procinfo = activityManager.getRunningAppProcesses();
        for (int i = 0; i < procinfo.size(); i++) {

            if(procinfo.get(i).processName.equals("com.xsinfosol.helpdesk_customer"))
            {
                notification.number=++notificationcount;
                notificationcount =notificationcount++;
                setBadgeNotify(getApplicationContext(),notificationcount);
                break;

            }

        }




        {
        // Wake Android Device when notification received
        PowerManager pm = (PowerManager) context
        .getSystemService(Context.POWER_SERVICE);
        final PowerManager.WakeLock mWakelock = pm.newWakeLock(
        PowerManager.FULL_WAKE_LOCK
        | PowerManager.ACQUIRE_CAUSES_WAKEUP, "GCM_PUSH");
        mWakelock.acquire();

        // Timer before putting Android Device to sleep mode.
        Timer timer = new Timer();
        TimerTask task = new TimerTask() {
        public void run() {
        mWakelock.release();
        }
        };
        timer.schedule(task, 5000);
        }


    }
    @Override
    protected void onRegistered(Context arg0, String arg1) {
        // TODO Auto-generated method stub

    }
    @Override
    protected void onUnregistered(Context arg0, String arg1) {
        // TODO Auto-generated method stub

    }





     private static void setBadgeNotify(Context context, int count) {
            String launcherClassName = getLauncherClassName(context);
            if (launcherClassName == null) {
                return; 
            }

            Intent intent = new Intent();
            intent.setAction("com.sonyericsson.home.action.UPDATE_BADGE");
            intent.putExtra("com.sonyericsson.home.intent.extra.badge.ACTIVITY_NAME",launcherClassName );//"com.xsinfosol.helpdesk_customer.MainActivity"
            intent.putExtra("com.sonyericsson.home.intent.extra.badge.SHOW_MESSAGE", true);
            intent.putExtra("com.sonyericsson.home.intent.extra.badge.MESSAGE", String.valueOf(count));
            intent.putExtra("com.sonyericsson.home.intent.extra.badge.PACKAGE_NAME",context.getPackageName() );//"com.xsinfosol.helpdesk_customer"

            context.sendBroadcast(intent);
        }   


     private static String getLauncherClassName(Context context) {

            PackageManager pm = context.getPackageManager();

            Intent intent = new Intent(Intent.ACTION_MAIN);
            intent.addCategory(Intent.CATEGORY_LAUNCHER);

            List<ResolveInfo> resolveInfos = pm.queryIntentActivities(intent, 0);
            for (ResolveInfo resolveInfo : resolveInfos) {
                String pkgName = resolveInfo.activityInfo.applicationInfo.packageName;
                if (pkgName.equalsIgnoreCase(context.getPackageName())) {
                    String className = resolveInfo.activityInfo.name;
                    return className;
                }
            }
            return null;
        }



}

下面是 GCMintentService 的代码，我在其中获取消息并显示通知。

public class GCMintentService extends WakefulBroadcastReceiver {

    private static final String TAG= "GCM Tutorial::Service";

    public static final String senderId="************";

    @Override
    public void onReceive(Context context, Intent intent) {
        ComponentName comName = new ComponentName(context.getPackageName(), GCMMessageHandler.class.getName()); 
        startWakefulService(context, (intent.setComponent(comName)));
        setResultCode(Activity.RESULT_OK);
}
}

将此值更改为所需的可绘制图像

.setSmallIcon(R.drawable.assignedtickets)

要更新操作栏图标，您需要获取 Activity 实例

如果你在 Activity 中，那么

this.getActionBar.setIcon()

如果在 fragment 中则

getActivity.getActionBar.setIcon()
