新 NotificationCompat.BigPictureStyle() 显示错误无法为通知充气视图

Question

我想在通知栏中显示我正在使用此代码的大尺寸图像

我的图像来自 server.so 在 AsyncTask 中将其转换为位图并在活动图像视图中显示其工作正常，但是当使用通知生成器在通知中加载相同的位图时显示错误

 Bitmap img = BitmapFactory.decodeByteArray(result, 0, result.length);
                imgView.setImageBitmap(img);
  NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(ctx)
                        .setSmallIcon(R.mipmap.ic_launcher)
                        .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher))
                        .setContentTitle("hahahha").setStyle(new NotificationCompat.BigPictureStyle()
                                .bigPicture(img))
                        .setAutoCancel(true);
   NotificationManager notificationManager =
                        (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
   notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());

您从 api 响应中获取图像并转换为 Bitmap，但在您的通知构建器中添加了可绘制的图像，只需更改此设置

Bitmap img = BitmapFactory.decodeByteArray(result, 0, result.length);              
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(ctx)
                    .setSmallIcon(R.mipmap.ic_launcher)
                    .setLargeIcon(img)
                    .setContentTitle("hahahha").setStyle(new NotificationCompat.BigPictureStyle()
                            .bigPicture(img))
                    .setAutoCancel(true); 

现在要设置大图样式

Notification notif = new Notification.Builder(context)
     .setContentTitle("hahahha")
     .setContentText("content")
     .setSmallIcon(R.drawable.ic_launcher)
     .setLargeIcon(bitmap)
     .setStyle(new Notification.BigPictureStyle()
     .bigPicture(img)
     .setBigContentTitle("hahahha"))
     .build();

试试他的，为我工作

使用线程从服务器获取图片

new Thread(new Runnable() {
    @Override
    public void run() {
        try {
            showBigNotification();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}).start();

发送通知

private void showBigNotification() {
    Bitmap bitmap = getBitmapFromURL(**Your image url**);

    Notification.BigPictureStyle bigPictureStyle = new Notification.BigPictureStyle();
    bigPictureStyle.setBigContentTitle("title");
    bigPictureStyle.setSummaryText("message");
    bigPictureStyle.bigPicture(bitmap);

    Intent notificationIntent = new Intent(mContext, MainActivity.class);
    PendingIntent contentIntent = PendingIntent.getActivity(mContext,
                101, notificationIntent,
                PendingIntent.FLAG_CANCEL_CURRENT);

    NotificationManager nm = (NotificationManager) mContext
                .getSystemService(Context.NOTIFICATION_SERVICE);

    Resources res = mContext.getResources();
    Notification.Builder builder = new Notification.Builder(mContext);

    builder.setContentIntent(contentIntent)
                .setSmallIcon(R.mipmap.ic_launcher)
                .setLargeIcon(BitmapFactory.decodeResource(mContext.getResources(), R.mipmap.ic_launcher))
                .setTicker(res.getString(R.string.app_name))
                .setStyle(bigPictureStyle)
                .setWhen(System.currentTimeMillis())
                .setAutoCancel(true)
                .setContentTitle("Title")
                .setContentText("Message");
    Notification n = builder.build();

    if (nm != null) {
        nm.notify(1001, n);
    }
}

从服务器获取图片

public Bitmap getBitmapFromURL(String strURL) {
    try {
        URL url = new URL(strURL);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setDoInput(true);
        connection.connect();
        InputStream input = connection.getInputStream();
        return BitmapFactory.decodeStream(input);
    } catch (MalformedURLException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    return null;
}
