Android5.0特性

TextInputView见名知其意，主要用于用户输入展示效果，内置动画，提示错误方法等，为Android5.0的一款控件！

间断花费时间1-2日！解决了错误信息提示只显示一次的问题！

存在问题：
1.第一次Edit内输入信息，加入规则之后可正常提示，但是当再次输入的时候，提示信息为空，且会空出控件底部的一段空间
2.引用控件，sdk23与sdk24的不同

解决方案 :
- 尝试引用对应sdk的版本，sdk24内置一款TextInputEditText
- sdk23内没有TextInputEditText控件，引用不到实属正常

实现原理：
大多的特性均是基于代码底层进行开发，此篇的TextInputView使用了Android原有的EditView与TextView，所以我们同样可以使用这俩个控件进行text监听与逻辑判断处理

实现方式：
1.使用最基本的原始方法进行设置
2.内部封装处理，传入对应参数
3.EditText与TextView的实现方式

布局样式：

<android.support.design.widget.TextInputLayout        android:layout_marginTop="20dp"                android:layout_width="match_parent"        android:layout_height="wrap_content">        <EditText            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:inputType="textEmailAddress" />    </android.support.design.widget.TextInputLayout>
