安卓程序添加socket客户端

一、添加socket客户端

直接在按键的响应方法中添加socket客户端
注意的是socket服务端和客户端都不允许放在主线程下运行，所以创建新的线程单独运行

	//Socket客户端
    public void send(){
		try {
			@SuppressWarnings("resource")
			Socket client = new Socket("192.168.43.135", 8080);
			OutputStream out = client.getOutputStream();
			String data = "hello";
			out.write(data.getBytes());
		} catch (UnknownHostException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}	
	}
	//按键响应方法
    public void sendMessage(View v) {
    	//socket服务端和客户端都不允许放在主线程下运行，所以创建新的线程单独运行
    	new Thread(new Runnable() {
			@Override
			public void run() {
				send();
			}
		}).start();
    }

二、多组件使用客户端发送数据

package com.example;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import com.socketClient.Client;

public class MainActivity extends Activity {

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

	public void sendMessage(View v) {
		switch(v.getId()) {
			case R.id.button1:
				Client.send("go");	break;
			case R.id.button2:
				Client.send("go");	break;
			case R.id.button3:
				Client.send("go");	break;			
		}
	}
}

客户端放在新的Java文件中

package com.socketClient;

import java.io.IOException;
import java.io.OutputStream;
import java.net.Socket;
import java.net.UnknownHostException;

public class Client {

	public static void send(final String data) {
		new Thread(new Runnable() {
			@Override
			public void run() {
				try {
					Socket client = new Socket("192.168.43.135", 8080);
					OutputStream out = client.getOutputStream();
					out.write(data.getBytes());
				} catch (UnknownHostException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				} catch (IOException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
			}
		}).start();
	}
}
