原生android端editText控件，用于在nvue页面使用
使用方法
<editText ref="edit1" textSize="16" textColor="#1680ea" @afterTextChanged="afterTextChanged"
hint="請掃碼" hintTextColor="#D9001B"></editText>

支持的参数有textSize（输入框字号），textColor（输入框文字颜色）hint（描述文案）	hintTextColor（描述文案颜色）

组件本身支持设置class,style,字号和颜色只能通过预定的参数设置
回调方法：
@beforeTextChanged 内容变化前
@onTextChanged 内容发送变化
@afterTextChanged 内容变化后
返回值 {detail:{text:'111'}}
方法：
通过ref调用组件方法
focus（获得焦点）
blur（失去焦点）
showKeyboard（显示键盘）
hideKeyboard（隐藏键盘）
setText（修改值）
