实现功能

app收到消息，并且展示到控件上

Socket客户端代码

MainActivity.java

package com.example.socket.dzz;

import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.view.View;
import android.widget.TextView;

import com.example.socket.dzz.nets.NetUtils;

public class MainActivity extends Activity {

	Handler handler;
	TextView tx;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        tx = (TextView) findViewById(R.id.tx);
        handler = new Handler(){
        	@Override
        	public void handleMessage(Message msg) {
        		// TODO Auto-generated method stub
        		super.handleMessage(msg);
        		Bundle b = msg.getData();
        		String str = b.getString("msg");
        		tx.setText(str);
        	}
        };
    }
    
    public void sendMessage(View v){
    	switch(v.getId()){
    		case R.id.fh:
    			NetUtils.sendMessageHandler("gofoward", handler);
    			break;
    	}
    	
    }
}

NetUtils.java

package com.example.socket.dzz.nets;

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

import android.os.Bundle;
import android.os.Handler;
import android.os.Message;

public class NetUtils {
	public static void sendMessageHandler(final String command, final Handler h){
    	new Thread(new Runnable() {
			@Override
			public void run() {
				// TODO Auto-generated method stub
				try {
					Socket client = new Socket("192.168.1.103", 8800);
					OutputStream out = client.getOutputStream();  //发送数据的通道
					out.write(command.getBytes());  // 发送通道，发送数据
					
					int len;
					InputStream in = client.getInputStream();
					byte[] data = new byte[128];
					len = in.read(data);
					String str = new String(data, 0, len);
					Message msg = new Message();
					
					Bundle b = new Bundle();
					b.putString("msg", str);
					msg.setData(b);
					h.sendMessage(msg);
					
				}catch (IOException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
			}
		}).start();
    	
    }
