String HttpPost(String aURL) throws Exception

        URL url = new URL(aURL);
        BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
        String response="";

        while ((inputLine = in.readLine()) != null)
            response+=inputLine;    

      //  Log.i(TAG, response);
        if(in!=null)

public void userpost(View v){

问题是您在UI或主线程中使用Web服务，因此您需要将AsyncTask用于Web服务。见link。这给出了如何使用AsyncTask的想法。这是最常见的错误

这个链接提到你的一切。我只在这里添加代码。

第1步：首先，您需要像这样调用Asynctask

new DownloadFilesTask().execute(url1, url2, url3);

第2步：实现您的Async类

private class DownloadFilesTask extends AsyncTask<URL, Integer, Long> {
     protected Long doInBackground(URL... urls) {
         int count = urls.length;
         long totalSize = 0;
         for (int i = 0; i < count; i++) {
             totalSize += Downloader.downloadFile(urls[i]);
             publishProgress((int) ((i / (float) count) * 100));
             // Escape early if cancel() is called
             if (isCancelled()) break;
         }
         return totalSize;
     }

     protected void onProgressUpdate(Integer... progress) {
         setProgressPercent(progress[0]);
     }

     protected void onPostExecute(Long result) {
         showDialog("Downloaded " + result + " bytes");
     }
 }

注意：有三种方法onPreExecute()，doInBackground()和onPostExecute()。您的下载是否适用于doInBackground()方法。

这只是示例代码。试试你自己的。
