Question

我正在开发一个Android应用程序，其中我正在使用GCM添加通知服务。问题是我想在点击通知时打开特定活动。我不知道如何执行此任务。我还想更改服务器端和客户端的更改。活动名称由服务器提供，然后当我单击通知时，活动将打开。请帮帮我。

我试过这段代码。

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Special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());
 }

因此也为特殊创造方法。希望这有助于GOOD LUCK

您可以指定任何活动作为推送通知的接收者：

<intent-filter>
<action android:name="PACKAGE_NAME.MESSAGE"/>
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>

此活动的意图过滤器指定响应推送通知将启动哪个活动（PACKAGE_NAME是您的Android应用包）

因此，您可以在活动中添加此意图过滤器，然后单击“推送通知”即可打开该活动。

在Pending Intent中提及您的具体活动（此处为MainActivity.class）

Intent notificationIntent = new Intent(context, MainActivity.class);

PendingIntent intent = PendingIntent.getActivity(context, 0, notificationIntent, 0);

Answer 4

private void notificationMethod(){

        NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(yourActivity.this)
                .setSmallIcon(R.drawable.app_icon)
                .setContentTitle("title")
                .setContentText("text");
        // Creates an explicit intent for an Activity in your app
        Intent resultIntent = new Intent(yourActivity.this, wantToOpenActivity.this);

        // The stack builder object will contain an artificial back stack for the
        // started Activity.
        // This ensures that navigating backward from the Activity leads out of
        // your application to the Home screen.
        TaskStackBuilder stackBuilder = TaskStackBuilder.create(yourActivity.this);
        // Adds the back stack for the Intent (but not the Intent itself)
        stackBuilder.addParentStack( wantToOpenActivity.this);
        // Adds the Intent that starts the Activity to the top of the stack
        stackBuilder.addNextIntent(resultIntent);
        PendingIntent resultPendingIntent =
                stackBuilder.getPendingIntent(
                    0,
                    PendingIntent.FLAG_UPDATE_CURRENT
                );
        mBuilder.setContentIntent(resultPendingIntent);
        NotificationManager mNotificationManager =
            (NotificationManager) getActivity().getSystemService(Context.NOTIFICATION_SERVICE);
        // mId allows you to update the notification later on.
        int mId=001;;
        mNotificationManager.notify(mId, mBuilder.build());
    }

Answer 5

<intent-filter>
      <action android:name="android.intent.action.VIEW"/>
     <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

我遇到了类似的问题，在我加入＆＃34; android.intent.action.VIEW＆＃34;后，活动就开始了。
