        花了一个天一夜,搞了这个小东西-安卓手机令牌.其实,我这边分享,看网上东西也没多少.这就分享了.因为这个会给公司用.有些东西就不方便透露了.希望大家体谅.还有如果需要找我沟通,加群吧!在页面中会有三处出现.

　　android 也不难学,承认花了时间1/2 花在界面上.界面需要经验的积累.和大哥有说有笑搞着界面,我们浩二有木有.要吐槽的可以吐槽,要啥的说啥.

 java 与  C#服务端交互

　　这种东西 一抓一大把,我这边简单就用了下ksoap2-android-assembly-2.4-jar-with-dependencies.jar,发现交互很简单,url call下然后 调用方法返回值.所以这边代码:

    private String getDateTime() throws Exception {
        // UIHelper.ToastMessage(MainActivity.this, "进去");

        SoapObject rpc = new SoapObject(NAMESPACE, GET_TIME_METHOD_NAME);

        AndroidHttpTransport ht = new AndroidHttpTransport(URL);
        ht.debug = true;

        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                SoapEnvelope.VER11);
        envelope.bodyOut = rpc;
        envelope.dotNet = true;
        envelope.setOutputSoapObject(rpc);

        try {
            ht.call(GET_TIME_SOAP_ACTION, envelope);
        } catch (Exception e) {
            // 校准时间网络错误
            UIHelper.ToastMessage(MainActivity.this, "未连接网络或网络异常");
        }

        SoapObject result = (SoapObject) envelope.bodyIn;
        SoapPrimitive detail = (SoapPrimitive) result
                .getProperty("GetDateTimeResult");

        System.out.println("result" + result);
        System.out.println("detail" + detail);

        // UIHelper.ToastMessage(MainActivity.this, detail.toString());

        return detail.toString();
    }

倒计时和顺计时技术

　　android端倒计时:

// 倒计时
    Handler handler = new Handler() {

        public void handleMessage(Message msg) { // handle message
            switch (msg.what) {
            case 1:
                recLen--;
                
                if (recLen < 10) {
                    txtTextTimeBack.setText("0" + recLen);
                    
                }else{
                    txtTextTimeBack.setText("" + recLen);
                    
                }if (recLen > 0) {
                    Message message = handler.obtainMessage(1);
                    handler.sendMessageDelayed(message, 1000); // send message
                } else {
                    // 重新获取序列号
                    Message message = handler.obtainMessage(1);
                    handler.sendMessageDelayed(message, 1000); // send message
                    String dateTime;

                    try {
                        dateTime = DateFormate.getDateTime();
                        txtDateTime.setText(dateTime);
                    } catch (Exception e) {
                        UIHelper.ToastMessage(MainActivity.this, "未知错误");
                        e.printStackTrace();
                    }

                    turnTimeBack();

                    try {
                        showTheNumber();
                    } catch (Exception e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                }
            }

            super.handleMessage(msg);
        }
    };

顺时采用上面倒计时的方法里面,加起来合为60

String ss = DateFormate.getStringFromDate(DateFormate.getDateFormString(txtDateTime.getText().toString()));
                
                if (recLen > 50)
                {
                    ss += "0" + (60-recLen);
                }
                else {
                    ss += "" + (60-recLen);
                }
                
                txtDateTime.setText(ss);

口令生成

　　这是核心关键.所以我这边生成的算法就不方便透露了.像沟通的话,加我的群讨论.口令可以根据 序列号 时间 特定字符串生成.这边我提供下 有关算法,像MD5...等都是常用的

String key = String.valueOf((dateTimeLong ^ serialNumberLong));
        
        String result = null;
        
        MessageDigest mad5 =null;
        try
        {
            mad5 = MessageDigest.getInstance("MD5");
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }
