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.

界面

代码:

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();        }
