ProgressDialog并不只显示闪烁 [英] ProgressDialog doesn't show just flashes

问题描述

我有耗时功能上传/ *约10秒* /。开始上传前，我想显示ProgressDialog，当上传完成解雇ProgressDialog，我试图像

I have time consuming function upload /* around 10 sec */. I am trying before start upload to show ProgressDialog and when upload finishes to dismiss ProgressDialog and I trying like

        pd = ProgressDialog.show(Uploader.this,
                "Connecting...", "Uploading",
                true, false);
        Uploader.this
        .runOnUiThread(new Runnable() {
            public void run() {

                upload();
                handler.sendEmptyMessage(0);

            }
        });

问题是，进展并不说明10秒左右，只有闪烁，像是第一次上传，然后调用表演和解雇（我试图把上面显示线程，但它是一样的）。
该怎么办 ？ （上载是无效的功能）

Problem is that Progress doesn't show for around 10s, only flashes, like it first upload and then call show and dismiss ( I tried to put show above thread, but it is the same ). What to do ? ( Upload is void function)

推荐答案

您是上传code不应该在UI线程上运行。如果确实如此，那么它会阻止从其他做任何事情，如显示一个进度对话框线程。保存进度对话框，显示它，产生一个新的线程来完成上传，而上传完成后，使用处理，回到UI线程并关闭进度对话框

You're upload code should not run on the UI thread. If it does, then it will block that thread from doing anything else, such as displaying a progress dialog. Save your progress dialog, show it, spawn a new thread to do the upload, and when the upload is complete, use a Handler to get back to the UI thread and close the progress dialog
