http异步请求

1、加载异步请求包文件

2、java代码

package com.example.asynchttp;

import org.apache.http.Header;

import com.loopj.android.http.AsyncHttpClient;

import com.loopj.android.http.AsyncHttpResponseHandler;

import com.loopj.android.http.RequestParams;

import android.os.Bundle;

import android.app.Activity;

import android.view.Menu;

import android.view.View;

import android.widget.Toast;

public class MainActivity extends Activity {

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

    }

    public void click(View view){

        AsyncHttpClient client = new AsyncHttpClient();

        String path = "http://192.168.1.100/android/add.php";

        client.get(path, new AsyncHttpResponseHandler() {

            @Override

            public void onSuccess(int statusCode, Header[] headers,

                    byte[] responseBody) {

                // TODO Auto-generated method stub

                String result = new String(responseBody);

                Toast.makeText(MainActivity.this, result, 0).show();

            }

            @Override

            public void onFailure(int statusCode, Header[] headers,

                    byte[] responseBody, Throwable error) {

                // TODO Auto-generated method stub

                Toast.makeText(MainActivity.this, "失败!", 0).show();

            }

        });

    }

    public void click2(View view){

        AsyncHttpClient client = new AsyncHttpClient();

        String url = "http://192.168.0.86/android/add.php";

        RequestParams params = new RequestParams();

        params.put("username", "zhangsan");

        params.put("password", "123456");

        client.post(url, params, new AsyncHttpResponseHandler(){

            @Override

            public void onSuccess(int statusCode, Header[] headers,

                    byte[] responseBody) {

                // TODO Auto-generated method stub

                String result = new String(responseBody);

                Toast.makeText(MainActivity.this, result, 0).show();

            }

            @Override

            public void onFailure(int statusCode, Header[] headers,

                    byte[] responseBody, Throwable error) {

                // TODO Auto-generated method stub

                Toast.makeText(MainActivity.this, "请求失败!", 0).show();

            }

        });

    }
