HttpPost 不工作它没有显示任何错误，但它没有在 php localhost 中存储任何内容，

Question

此代码在单击按钮时不起作用，它不显示 toast 消息，也不向本地主机 php 服务器发送数据。我正在运行一个 android 硬件设备进行调试，请让我知道代码哪里不正确。

public class MainActivity extends Activity {

EditText etName,etEmail,etAge;
Button bSubmit;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //Setup strict mode policy
    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
    StrictMode.setThreadPolicy(policy);


    setContentView(R.layout.activity_main);

    //For the name
    etName = (EditText) findViewById(R.id.editName);
    //For the Age
    etAge  = (EditText) findViewById(R.id.editAge);
    //For the Email
    etEmail = (EditText) findViewById(R.id.editEmail);

    //setup Onclick Button
    bSubmit = (Button) findViewById(R.id.buttonSubmit);

    bSubmit.setOnClickListener(new View.OnClickListener() {
        //Onclick Listener
        InputStream is = null;
        @Override
        public void onClick(View arg0) {

           //Storing Values inside the string
            String name = ""+etName.getText().toString();
            String age = ""+etAge.getText().toString();
            String email = ""+etEmail.getText().toString();

            //Setting name pair values
            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();


            //Adding String Variable inside the name value pairs
            nameValuePairs.add(new BasicNameValuePair("name", name));
            nameValuePairs.add(new BasicNameValuePair("age", age));
            nameValuePairs.add(new BasicNameValuePair("email",email));
            //Setting up HTTP Client

            try{

                HttpClient httpClient =  new DefaultHttpClient();
                HttpPost httpPost= new HttpPost("http://10.0.2.2:1337/tutorial.php");
                //Passing the name value
                httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

                //Getting the response
                HttpResponse response = httpClient.execute(httpPost);

                //Setting up the entity
                HttpEntity entity = response.getEntity();

                    is = entity.getContent();

                        //Display if data entered successfully
                String msg = "Data entered successfully";
                Toast.makeText(getApplicationContext(),msg, Toast.LENGTH_LONG).show();
                //Setting up the content inside an input stream

            }catch (ClientProtocolException e){
               Log.e("ClientProtocol","Log_tag");
                e.printStackTrace();
            }catch (IOException e)
            {
                Log.e("Log tag","IOException");
                e.printStackTrace();

            }
        }
    });
}


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}

}

清单文件

<?xml version="1.0" encoding="utf-8"?>

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

(编辑) 这是我正在使用的 php 文件代码 Xampp (localhost:1337) $name=isset($_POST['name']; $age=isset($_POST['age']); $email=isset($_POST['email']);

   mysql_query("insert into newtable(name,age,email) values('{$name}','{$age}','{$email}')");

这里有几个错误，我一一列举。

根据您的描述，您提到您的运行在本地主机 PHP 服务器（我假设它是 WAMP 服务器），并且您还提到您是运行真实硬件设备中的应用程序。如果你的运行在真实设备中，那么 localhost 是没有用的。您需要自己的服务器（您可以找到很多免费托管网站）。如果您只想使用 WAMP，请在模拟器中对其进行测试。
不允许在主线程中执行网络操作（这就是您使用严格模式的原因 - 删除这两行）。学习使用 Async Task 进行网络操作。

这对你来说是一个很好的参考
