Volley的post使用

直接看代码，注意在manifest中加入Internet权限

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

package com.turtle920.volleydemo;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

import com.android.volley.AuthFailureError;
import com.android.volley.Request;
import com.android.volley.RequestQueue;
import com.android.volley.Response;
import com.android.volley.VolleyError;
import com.android.volley.toolbox.StringRequest;
import com.android.volley.toolbox.Volley;

import java.util.HashMap;
import java.util.Map;

public class MainActivity extends AppCompatActivity {

    static final private String URL = "http://192.168.8.6/insert.php";

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

        RequestQueue mQueue = Volley.newRequestQueue(getApplicationContext());

        StringRequest stringRequest = new StringRequest(Request.Method.POST, URL,
                new Response.Listener<String>() {
                    @Override
                    public void onResponse(String response) {
                        Log.d("TAG", response);//response为服务器返回的string
                    }
                }, new Response.ErrorListener() {
                    @Override
                    public void onErrorResponse(VolleyError error) {
                        Log.e("TAG", error.getMessage(), error);
                    }
        }){
            @Override
            protected Map<String, String> getParams() throws AuthFailureError {
                Map<String, String> map = new HashMap<String, String>();
                map.put("firstname", "杰伦");
                map.put("lastname", "htt");
                map.put("age", "18");
                return map;
            }
        };

        mQueue.add(stringRequest);

    }
}

Volley是个异步线程，需要在onResponse下完成要干的事，即使代码很丑
