java - 如何在点击推送通知时打开特定 Activity

Question

我正在开发一个Android应用程序，在该应用程序中我使用GCM添加​​通知服务。问题是我想在单击通知时打开特定 Activity 。我不知道如何执行此任务。我还想更改服务器端和客户端上的更改。 Activity 名称由服务器提供，然后当我单击通知时 Activity 将打开。请帮助我。

我已经尝试过这段代码。

protected void onMessage(Context context, Intent intent) {
        Log.i(TAG,
                "Received message. Extras:*************************************************** "
                        + intent.getExtras());
        // String message = getString(R.string.gcm_message);
        // displayMessage(context, message);
        // notifies user

        String inAction = intent.getAction();
        ArrayList<Notify> notifyData = new ArrayList<Notify>();
        if (inAction.equals("com.google.android.c2dm.intent.RECEIVE")) {

            String json_info = intent.getExtras().getString("data");
            Notify notify = new Notify();
            if (json_info != null) {
                try {

                    JSONObject jsonObj = new JSONObject(json_info);
                    notify.setdetail(jsonObj.get("Detail").toString());
                    notify.setappUpdate(jsonObj.get("App Update").toString());
                    notify.setcontentUpdate(jsonObj.get("Content Update")
                            .toString());
                    notify.setSpecial(jsonObj.get("Special Event").toString());
                    notify.setSpecialContent(jsonObj.get("splEvtDes")
                            .toString());
                    notifyData.add(notify);
                } catch (JSONException e) {
                    // do nothing
                    return;
                }
            } else {

                notify.setdetail(intent.getStringExtra("Detail"));
                notify.setappUpdate(intent.getStringExtra("App Update"));
                notify.setcontentUpdate(intent.getStringExtra("Content Update"));
                notify.setSpecial(intent.getStringExtra("Special Event"));
                notify.setSpecialContent(intent.getStringExtra("splEvtDes"));
                notifyData.add(notify);
            }

        }
        String message = null;
        if (notifyData.get(0).getappUpdate().equalsIgnoreCase("YES")) {
            createNotificationForAppUpdate();
        } else if (notifyData.get(0).getcontentUpdate().equalsIgnoreCase("YES")) {
            message = notifyData.get(0).getdetail();

            generateNotification(context, message);
        } else {
            System.out
                    .println("=-----------------------------inside else_________________________");
            message = notifyData.get(0).getSpecialContent();
            generateNotification(context, message);

        }

    }

根据您的示例代码，似乎您正在尝试在 Appupdate、contentUpdate 和特殊内容的情况下执行不同的操作。因此，根据您的代码创建三个方法。第一个用于 AppUpdate，第二个用于内容更新，最后一个用于特殊内容。

         String message = null;
                if (notifyData.get(0).getappUpdate().equalsIgnoreCase("YES")) {
                    createNotificationForAppUpdate();
    //This will notify for App update
                } else if (notifyData.get(0).getcontentUpdate().equalsIgnoreCase("YES")) {
                    message = notifyData.get(0).getdetail();
        //This will notify for Content updte
                    generateNotification(context, message);
                } else {

//This will notify for special content
                    message = notifyData.get(0).getSpecialContent();
                    generateNotification(context, message);

                }

AppUpdate方法

private void createNotificationForAppUpdate()
{
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("Enter here playstore link"));
startActivity(browserIntent);
}

内容通知方法。

 private void generateNotification(Context context,String message){
int notificationId = 001;
// Build intent for notification content
Intent viewIntent = new Intent(context, YourActivity.class);
viewIntent.putExtra(EXTRA_EVENT_ID, eventId);
PendingIntent viewPendingIntent =
        PendingIntent.getActivity(context, 0, viewIntent, 0);

NotificationCompat.Builder notificationBuilder =
        new NotificationCompat.Builder(this)
        .setSmallIcon(R.drawable.ic_event)
        .setContentTitle("Title")
        .setContentText(message)
        .setContentIntent(viewPendingIntent);

// Get an instance of the NotificationManager service
NotificationManagerCompat notificationManager =
        NotificationManagerCompat.from(context);

// Build the notification and issues it with notification manager.
notificationManager.notify(notificationId, notificationBuilder.build());
 }

也相应地创建特殊方法。 希望这会有所帮助，祝你好运
