Android忘记密码功能实现

连续好几天学习都没有什么进展，然而在今天这个烂漫的日子。突然有了学习的动力。想起来前几日老师给布置的android忘记密码的功能实现。今天也有了想法。就是按照老师的建议，简单的回答一个问题，实现此功能。我就模仿之前写的登录的例子。实现了此功能。我的想法是：回答之前绑定的手机号。如果正确则忘记密码成功。反之失败。

现在开始上效果图片：

android端的代码：

添加权限：

<uses-permission android:name="android.permission.INTERNET"/>

PHP代码：

<?phpif(isset($_POST['button'])){    $phone=$_POST['phone'];//得到用户输入的手机号      if($phone == "123456"){//假设用户的手机号为123456        echo '哈哈。。。成功忘记密码';        }else{         echo '操作失败！';}    }else{    echo 'test!';}?>
