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.

復制代码
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:
復制代码
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();
}
復制代码
倒计时和顺计时技术
android端倒计时:
復制代码
// 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);
}
};
復制代码
顺时采用上面倒计时的方法里面,加起来合为60
復制代码
String ss = DateFormate.getStringFromDate(DateFormate.getDateFormString(txtDateTime.getText().toString()));
if (recLen > 50)
{
ss += "0" + (60-recLen);
}
else {
ss += "" + (60-recLen);
}
txtDateTime.setText(ss);
復制代码
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
復制代码
String key = String.valueOf((dateTimeLong ^ serialNumberLong));
String result = null;
MessageDigest mad5 =null;
try
{
mad5 = MessageDigest.getInstance("MD5");
}
catch (Exception e)
{
e.printStackTrace();
}
