Android端与笔记本利用局域网进行FTP通信

先看图
打开前：



打开后：





Activity类：（不要纠结于这个类的完整性，主要看一下怎么操作ServerFtplet类即可）

import android.content.Context;import android.net.wifi.WifiInfo;import android.net.wifi.WifiManager;import android.os.Bundle;import android.view.View;import android.widget.EditText;import android.widget.ImageView;import android.widget.TextView;import com.mb.goods.app.BaseActivity;import com.mb.goods.app.R;import com.mb.goods.util.ServerFtplet;/** * 远程管理 * @author pythoner *  */public class RemoteManagementActivity extends BaseActivity implements View.OnClickListener{private Context context;private TextView tv_des;private EditText et_ftp;private WifiInfo wifiInfo;private boolean checked=false;private ServerFtplet ftp;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_remote_management);context = this;WifiManager wifiManager = (WifiManager) getSystemService(WIFI_SERVICE);wifiInfo = wifiManager.getConnectionInfo();ftp=ServerFtplet.getInstance();initActionBar("远程管理", null, null);initViews();}@Overridepublic void initViews() {// TODO Auto-generated method stubTextView tv_state=$(R.id.tv_state);tv_state.setText("网络状态\n"+wifiInfo.getSSID());//0到-50表示信号最好，-50到-70表示信号偏差，小于-70表示最差，有可能连接不上或者掉线int level=Math.abs(wifiInfo.getRssi());ImageView tv_rssi=$(R.id.tv_rssi);tv_rssi.setImageLevel(level);tv_des=$(R.id.tv_des);et_ftp=$(R.id.et_ftp);$(R.id.btn_ok).setOnClickListener(this);}@Overridepublic void updateViews(Object obj) {// TODO Auto-generated method stub}@Overridepublic void updateTheme(int color) {super.updateTheme(color);setThemeDrawable(context, R.id.btn_ok);}@Overridepublic void onClick(View v) {// TODO Auto-generated method stubswitch (v.getId()) {case R.id.btn_ok:if(checked){tv_des.setText("打开后可以在计算机上管理本设备上的文件");et_ftp.setVisibility(View.GONE);et_ftp.setText("");((TextView)v).setText("打开");ftp.stop();}else{tv_des.setText("在计算机中输入:");et_ftp.setVisibility(View.VISIBLE);et_ftp.setText("ftp://"+getIP()+":"+ServerFtplet.PORT+"/");((TextView)v).setText("关闭");ftp.start();}checked=!checked;break;default:break;}} @Override    protected void onDestroy() {        super.onDestroy();        ftp.stop();    }}

关键的ServerFtplet工具类：

还要导入5个jar包（据说导入两个包就可以了，但我试了一下不行，所以导入了5个jar包），见附件
