推荐答案

尝试包装你的上传过程到AsyncTask的。所以，你必须在 doInBackground），载（在这里您可以上传您的图片的部分（实际上，具有一定的缓冲液），并经过每一部分都调用下载 publishProgress（）。在 onProgressUpdate（）方法你有新的进展状态更新你的用户界面的能力。您可以更新进度条，或百分之新值设置为TextView的 - 你想要做什么

Try to wrap your uploading process into AsyncTask. So, you'll have uploading in doInBackground(), where you can upload your image "by parts" (actually, with some buffer), and after each portion is downloaded call publishProgress(). In onProgressUpdate() method you have ability to update your ui with the new progress state. You can update your progress bar, or set new percent value to TextView - do what you want.
