                           SharedPreferences.Editor editor = sp.edit();                            editor.putString("name",result[1] );//键值对                            editor.commit();                        }                    } else                        mHandler.sendEmptyMessage(CODE_ERROR);

                   System.out.println("UnknownHostException e");                    mHandler.sendEmptyMessage(SERVER_ERROR);                } catch (IOException e) {                    e.printStackTrace();

使用方法如下：

  new SocketUtil().sendMessage("login" + '\n' + accout + '\n' + password +  '\n', login, mHandler);
   发送消息   
//初始化handler,SUCCESS,INTERNET ERROR 都是int  final Handler mHandler = new Handler() {            @Override            public void handleMessage(Message msg) {                super.handleMessage(msg);                                    if(msg.what== SUCCESS) {                        Toast.makeText(login.getApplicationContext(), "登录成功", Toast.LENGTH_SHORT).show();                        SharedPreferences sp = getSharedPreferences("user", Context.MODE_PRIVATE);                        SharedPreferences.Editor editor = sp.edit();                        editor.putString("account",ac.getText().toString());//键值对                        editor.putString("password",pw.getText().toString());                        editor.commit();                        Intent intent = new Intent(Login.this, Main.class);                        startActivity(intent);                        Login.this.finish();                    }                     else if(msg.what== INTERNET_ERROR) {                        Toast.makeText(login.getApplicationContext(), "登录失败，网络异常", Toast.LENGTH_SHORT).show();                    }                    else if(msg.what== SERVER_ERROR){                        Toast.makeText(login.getApplicationContext(), "登录失败,服务器异常", Toast.LENGTH_SHORT).show();                    }                    else if(msg.what== CODE_ERROR){                        Toast.makeText(login.getApplicationContext(), "登录失败,密码错误", Toast.LENGTH_SHORT).show();                    }            }        };
