时间选择

使用方法:配置为时间(dateTime:dateFormatStr="HH:mm:ss" dateTime:dateFormat="time")

<?xml version="1.0" encoding="UTF-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"        xmlns:dateTime="http://schemas.android.com/apk/res/com.app"/> <com.app.view.DatePickText  android:layout_marginLeft="7dp"   android:layout_width="230dp" android:layout_height="35dp" 	     android:id="@+id/v_birthday" dateTime:dateFormatStr="HH:mm:ss" dateTime:dateFormat="time"/>

日期选择

使用方法:配置为日期(dateTime:dateFormatStr="yyyy-MM-dd" dateTime:dateFormat="date")

<?xml version="1.0" encoding="UTF-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"        xmlns:dateTime="http://schemas.android.com/apk/res/com.app"/> <com.app.view.DatePickText  android:layout_marginLeft="7dp"   android:layout_width="230dp" android:layout_height="35dp" 	     android:id="@+id/v_birthday" dateTime:dateFormatStr="yyyy-MM-dd" dateTime:dateFormat="date"/>

res/values/attrs.xml

<?xml version="1.0" encoding="utf-8"?><resources>    <declare-styleable name="DatePickText">                 <attr name="dateFormatStr" format="string"/>        <attr name="dateFormat" >               <!-- yyyy-MM-dd  --> 	         <enum name="date" value="0" />	         <!-- HH:mm:ss -->	         <enum name="time" value="1" />	     </attr>          </declare-styleable>  </resources>

实现类中用到的布局文件
date_pick_txt.xml
