自定义dialog、验证邮箱的dialog

当我们使用邮箱注册之后，应用应该提示用户去邮箱打开验证邮箱，这里我用了一个自定义的对话框实现这个功能，由于代码里面涉及到Bmob的部分功能，所以没有了解过Bmob的同学可以先去了解一下Bmob。

布局文件：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#fff"
    android:orientation="vertical">

    <TextView
        android:id="@+id/validate_dialog_email_text"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="6"
        android:padding="20dp"
        android:text="validate your email" />

    <Button
        android:id="@+id/validate_dialog_email_positive_btn"
        android:background="@drawable/bg_login_btn"
        android:layout_width="match_parent"
        android:layout_margin="5dp"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:text="positive" />

    <Button
        android:layout_marginLeft="5dp"
        android:layout_marginBottom="5dp"
        android:layout_marginRight="5dp"
        android:id="@+id/validate_dialog_email_negative_btn"
        android:background="@drawable/bg_login_btn"

        android:layout_height="0dp"
        android:layout_weight="1"
        android:text="negative" />
