I keep getting an error with network on main thread. It points to this part in the code: HttpResponse response = httpclient.execute(httppost);

This is my whole thread, but I don't understand how it says I am running it on the main thread when its most definitely on this specific separate thread!

new Thread(new Runnable() {

            @Override
            public void run() {

                 try {
                    HttpClient httpclient = new DefaultHttpClient();
                    HttpPost httppost = new HttpPost("http://mywebsite.com");
                    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
                    nameValuePairs.add(new BasicNameValuePair("username", name));
                    nameValuePairs.add(new BasicNameValuePair("phonenumber", phone));
                    httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

                    HttpResponse response = httpclient.execute(httppost);

                    result = EntityUtils.toString(response.getEntity());
                            edit_name.post(new Runnable() {
                        @Override
                        public void run() {
                            Toast.makeText(getActivity(), result, Toast.LENGTH_LONG).show();
                                }
                        });

                            db.submitFirstUser(name, phone);
                        }
                        catch(ClientProtocolException e){

                        }
                        catch (IOException e) {

                        }

                    }

                }).run();

您实际上是在调用在主线程上执行代码的 run() 方法。调用 start() 方法 instaed 将产生一个单独的线程。

run()只是调用run()Runnable 上的方法。您希望start()在新线程上实际启动 Runnable。

要启动一个线程使用start()，所以：

.run();

应该：

.start();

你应该开始线程

thread.start();

不与thread.run()
