}

package com.example.testinvokewebservice;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button btn= (Button)findViewById(R.id.btnLogin);
        btn.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                AsyncHttpTask http = new AsyncHttpTask();
                http.context = getApplicationContext();
                http.execute();
            }
        });
    }
}

AndroidManifest.xml增加权限方面的配置：

    <uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" >
    </uses-permission>
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" >
    </uses-permission>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" >
    </uses-permission>
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" >
    </uses-permission>
