android手机遥控Android机顶盒的Demo

就是采用socket与serversocket直接的通信

机顶盒端代码：

package cn.tvsr.remotedemo;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.ServerSocket;
import java.net.Socket;

import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.widget.Toast;

public class RemoteDemoActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        new Thread(new Runnable() {
			@Override
			public void run() {
				ServerSocket server;
				try {
				   server = new ServerSocket(6868);
				   System.out.println("Tvsr:Server Started!");
				   while(true){
						System.out.println("Tvsr:Server Runing!");
					    Socket client = server.accept();
					    InputStream ins = client.getInputStream();
					    BufferedReader br = new BufferedReader(new InputStreamReader(ins));
					    final String tmp = br.readLine();
					    final int keyCode = Integer.parseInt(tmp);
					    runOnUiThread(new Runnable() {
							@Override
							public void run() {
								Toast.makeText(getApplicationContext(),
										"Tvsr:Message received!-->keyCode:"+tmp,
										Toast.LENGTH_LONG).show();
								System.out.println("Tvsr:Message received!-->keyCode:"+tmp);
								RemoteDemoActivity.this.onKeyDown(keyCode,
										new KeyEvent(KeyEvent.ACTION_DOWN, keyCode));
							}
						});
				   }
				 } catch (IOException e) {
				    e.printStackTrace();
				}  

			}
		}).start();

    }
}

手机端代码：

package cn.tvsr.controldemo;

import java.io.IOException;
import java.io.OutputStream;
import java.io.PrintStream;
import java.net.Socket;
import java.net.UnknownHostException;
import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.widget.Toast;

public class ControlDemoActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }
	@Override
	public boolean onKeyDown(int keyCode, KeyEvent event) {
		Toast.makeText(getApplicationContext(),
				"keyCode:"+keyCode, Toast.LENGTH_LONG).show();
        try {
     	   Socket socket = new Socket("192.168.5.101", 6868);
     	   OutputStream os = socket.getOutputStream();
     	   PrintStream ps = new PrintStream(os);
     	   ps.println(keyCode);
     	   ps.flush();
     	   ps.close();
     	   os.close();
     	   socket.close();
     	} catch (UnknownHostException e) {
     		System.out.println("Tvsr:Server err!");
     		e.printStackTrace();
     	} catch (IOException e) {
     		System.out.println("Tvsr:Server err!");
     		e.printStackTrace();
     	}
		return super.onKeyDown(keyCode, event);
	}

}
