【问题标题】：Push notifications with big Images using cordova push plugin使用 Cordova 推送插件推送带有大图像的通知
【发布时间】：2015-02-25 12:18:10
【问题描述】：

我想获得类似 Flipkart 或 myntra 的推送通知。（推送通知将附带一张详细介绍优惠的大图，点击后将进入优惠区）。有谁知道如何完成它。我有这样的代码：

NotificationCompat.Builder mBuilder =
        new NotificationCompat.Builder(context)
            .setDefaults(defaults)
            .setStyle(new NotificationCompat.BigTextStyle().bigText("This is a test for push notification with big images."))
            .setLargeIcon(icon)
            .setSmallIcon(context.getApplicationInfo().icon)
            .setWhen(System.currentTimeMillis())
            .setContentTitle(extras.getString("title"))
            .setTicker(extras.getString("title"))
            .setContentIntent(contentIntent)
            .setAutoCancel(true);

以前，我为此创建了一个pull request。

重要代码：

public void createBigPicNotification(Context context, Bundle extras)
{
    NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    String appName = getAppName(this);

    .
    .
    .


    String bigPictureUrl= null;
    bigPictureUrl=extras.getString("bigPicture");
    Bitmap bigPictureBMP = null;
    if (bigPictureUrl != null) {
        try {
        URL url = new URL(bigPictureUrl);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setDoInput(true);
        connection.connect();
        InputStream input = connection.getInputStream();
            bigPictureBMP = BitmapFactory.decodeStream(input);
        } catch (IOException e) {
        e.printStackTrace();
        }
    }

    NotificationCompat.BigPictureStyle bigPicStyle = new
        NotificationCompat.BigPictureStyle();
    bigPicStyle.setBigContentTitle(extras.getString("title"));
    bigPicStyle.setSummaryText(extras.getString("message"));
    bigPicStyle.bigPicture(bigPictureBMP);

    NotificationCompat.Builder mBuilder =
        new NotificationCompat.Builder(context)
            .setDefaults(defaults)
            .setSmallIcon(context.getApplicationInfo().icon)
            .setWhen(System.currentTimeMillis())
            .setTicker(extras.getString("title"))
                    .setContentIntent(contentIntent)
                    .setAutoCancel(true)
                    .setStyle(bigPicStyle);

    String message = extras.getString("message");
    if (message != null) {
        mBuilder.setContentText(message);
    } else {
        mBuilder.setContentText("<missing message content>");
    }

    String msgcnt = extras.getString("msgcnt");
    if (msgcnt != null) {
        mBuilder.setNumber(Integer.parseInt(msgcnt));
    }

    int notId = 0;

    try {
        notId = Integer.parseInt(extras.getString("notId"));
    }
    catch(NumberFormatException e) {
        Log.e(TAG, "Number format exception - Error parsing Notification ID: " + e.getMessage());
    }
    catch(Exception e) {
        Log.e(TAG, "Number format exception - Error parsing Notification ID" + e.getMessage());
    }

    mNotificationManager.notify((String) appName, notId, mBuilder.build());
}
