1.验证码
2.倒计时
1.验证码：
1.1有一个免费的发送验证码的网站
http://www.mob.com/
注册 获得appky和appsecuret
1.2 进入android studio
首先AndroidMainfest.xml 添加许可
<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.RECEIVE_SMS" />
<uses-permission android:name="android.permission.GET_TASKS" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
1.2 在点开3，添加
1.3 点4，就是用到的那个module 添加
1.4 在要用的LoginActivity中，添加
这个发送验证码的方法，只需要在onclick里面调用
这个是判断验证码是否正确的方法。
至此 验证码就结束了。
LoginActivity在后面贴出来
接下来，倒计时：
2.倒计时：
好了。
