Android 如何仅以10%的增量调用NotificationManager

我有一个上传照片的服务。我有一个由NotificationManager更新的progressbar，但是它被称为multipletimes

IntentService[n相同的127行

我如何使经理只在上传10%的增量时通知

@Override
        public void writeTo(@NonNull BufferedSink sink) throws IOException {
            long fileLength = mFile.length();
            byte[] buffer = new byte[DEFAULT_BUFFER_SIZE];
            FileInputStream in = new FileInputStream(mFile);
            long uploaded = 0;
            int read;

            while (is_uploading && (read = in.read(buffer)) != -1) {
                int percent = 10* (int) (10 * uploaded / fileLength);
                mManager.notify(NOTIFICATION_ID, uploadingProgressNotification(String.valueOf(current_image_uploading+1), percent + 10));
                uploaded += read;
                sink.write(buffer, 0, read);
            }



        }

编辑：

Log.d（标记，“writeTo:test”）；

仍被多次调用，尽管它应该只有10次

IntentService[n相同的346行

使用以下代码：

int percent = (int) (100 * uploaded / fileLength);
if(percent % 10 == 0 && lastPercent != percent){
   lastPercent = percent;
   mManager.notify(NOTIFICATION_ID, uploadingProgressNotification(String.valueOf(current_image_uploading+1), percent));
}

---

同时创建globle变量

public int lastPercent=0；

hmmm我试过了，但它仍被多次调用

IntentService[n相同的1326行

int percent = (int) (100 * uploaded / fileLength);
if(percent % 10 == 0 && lastPercent != percent){
   lastPercent = percent;
   mManager.notify(NOTIFICATION_ID, uploadingProgressNotification(String.valueOf(current_image_uploading+1), percent));
}
