在我决定联系这里之前，我已经在 Stackoverflow 和互联网上查看了大部分 q/a 以获得答案。

我正在尝试在我的网站上调用 php 页面，并且在调用 httpclient.execute 时不断收到此错误：

08-19 12:42:33.889: E/AndroidRuntime(5340): FATAL EXCEPTION: main 08-19 12:42:33.889:
E/AndroidRuntime(5340): java.lang.IllegalStateException: Could not execute method of the activity 08-19 12:42:33.889: E/AndroidRuntime(5340):
at android.view.View$1.onClick(View.java:3046)

所以我通读了一些帖子，一件事我确定我有

<uses-permission android:name="android.permission.INTERNET" />

添加到我的清单（我这样做）下面是我从互联网上获得的一个片段，我从一个按钮 onclick 事件中调用它：

 HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost("http://mywebsite/scripts/test.php");

        try {
            // Add your data
            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(3);
            nameValuePairs.add(new BasicNameValuePair("function", "1"));
            nameValuePairs.add(new BasicNameValuePair("user", "username"));
            nameValuePairs.add(new BasicNameValuePair("pass", "123"));
            httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

            // Execute HTTP Post Request
            HttpResponse response = httpclient.execute(httppost);
            Log.e("log_tag", response.toString());


        } catch (ClientProtocolException e) {
             Log.e("log_tag", e.toString());
        } catch (IOException e) {
            Log.e("log_tag", e.toString());
        }

看起来你得到了 NetworkOnMainThreadException

尝试在不同的线程上运行它？

来自 Javadocs：

“当应用程序尝试在其主线程上执行网络操作时引发的异常。

这仅针对面向 Honeycomb SDK 或更高版本的应用程序抛出。允许以早期 SDK 版本为目标的应用程序在其主事件循环线程上进行网络连接，但非常不鼓励这样做。请参阅文档设计响应性。"

这是一个 NetworkOnMainThreadException ...您正在尝试在主线程上执行网络操作，在 Android 应用程序的主 UI 线程中是不允许的。

要解决此问题，请使用AsyncTask或Thread 并将您的网络相关操作放入其中。
