Android日期时间选择器-阿里云开发者社区

日期选择器是很多应用所具备的，比如设置一些任务的开始和结束时间。为了方便用户的同时也为了界面的好看，很多都是采用日期选择器，我在网上看了一下。很多的日期选择器个人感觉不是很好看，但是修改起来也有点麻烦，于是自己就写了一个demo。至于界面效果个人感觉也是很low，毕竟鄙人不是搞UI的，所以也就凑合着看吧。这些都不重要，因为这些是可以修改的。

如果想实现具有年月日的请看下面的注意里面的内容，下图是实现的分钟为00 15 30 45的如果想要0-59的请看下面的注意里面的内容

如果需要的是仿iOS的带有星期几的

首先界面弹出PopupWindow动画的实现，具体的代码如下

进入动画

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<translate
android:duration="500"
android:fromYDelta="100.0%p"
android:toYDelta="45" />
</set>

退出动画

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<translate
android:duration="500"
android:fromYDelta="0.0"
android:toYDelta="100.0%p" />
</set>
