-# ViewPager
+# YViewPagerDemo
+YViewPager,support horizontal and vertical,based on `support.v4.view.ViewPager`
+
+[中文版点这里](https://github.com/youngkaaa/YViewPagerDemo/blob/master/README_CH.md)
+
+## Usage
+
+### Gradle
+
+```
+compile 'cn.youngkaaa:yviewpager:0.2'
+```
+
+### Maven
+
+```
+<dependency>
+  <groupId>cn.youngkaaa</groupId>
+  <artifactId>yviewpager</artifactId>
+  <version>0.2</version>
+  <type>pom</type>
+</dependency>
+```
+
+## Intro
+The `YViewPager` is modified from the official `support.v4.view.ViewPager`,which support the direction of horizontal and vertical(new direction).You can use this lib just like the official `support.v4.view.ViewPager`,include the features of  `setPageTransformer()`、`addOnPageChangeListener()`、`setOffscreenPageLimit()` and so on,And also supported the `TabLayout`.
+
+
+## Feature
+
+### Direction
+
+On the base of the `support.v4.view.ViewPager`,add the property of `direction`. You can use it by：
+
+#### xml
+
+```
+<cn.youngkaaa.yviewpager.YViewPager
+    android:id="@+id/viewpager"
+    android:layout_width="match_parent"
+    android:layout_height="match_parent"
+    app:orientation="vertical"/>
+```
+
+just like the above xml.you can add the property `app:orientation` in `YViewPager` tag, the value of this property is `horizontal` and `vertical`.
+
+
+#### java code
+```
+mViewPager.setDirection(YViewPager.VERTICAL);
+
+mViewPager.setDirection(YViewPager.HORIZONTAL);
+
+```
+
+you can change the direction by calling the `YViewPager.setDirection()`。
+
+Tip：It's not recommended that change the direction when your application is running,which include a inflated `YViewPager`,because at this time the `YViewPager` may included the Fragments,which may has the deeply view hierarchy,and when you call the `setDriection()` may invaliate the layout,so may cause the application ANR or bad layout.but it's just not recommended,not unsupport!
+
+### Circulatory
+
+in `v1.2`,add the property of `circulatory`.you can use it by:
+
+#### xml
+
+```
+<cn.youngkaaa.yviewpager.YViewPager
+  android:id="@+id/viewpager1"
+  android:layout_width="match_parent"
+  android:layout_height="188dp"
+  app:circulatory="true"
+  app:orientation="horizontal"/>
+```
+
+yeah,you just need to add one line.
+
+#### java
+
+sorry,the property of `circulatory` do not support to change by using java code.
+
+
+## Version
+
+### v0.2
+
+add the `circulatory` property，which support the direction of horizontal and vertical  (`2017-2-26`)
+
+### v0.1
+
+support the direction of vertical and horizontal（`2017-2-22`）
+
+
+## Finally
+
+Because the `FragmentPagerAdapter` 、`FragmentStatePagerAdapter` and `PagerAdapter` has some methods are not br called in `YViewPager`，so I copy the code in this lib named `YFragmentPagerAdapter`、`YFragmentStatePagerAdapter` and `YPagerAdapter`，you can choose the `YxxxxxAdapter` in this lib which you needed!

+
+
+If you think this lib help you,you can give me a star to encourage me! thanks a lot

+# YViewPagerDemo
+YViewPager,support horizontal and vertical,based on `support.v4.view.ViewPager`
+
+# Preview

+
+![vertical](gif/vertical.gif)
+
+## 使用
+
+### Gradle
+
+```
+compile 'cn.youngkaaa:yviewpager:0.2'
+```
+
+### Maven
+
+```
+<dependency>
+  <groupId>cn.youngkaaa</groupId>
+  <artifactId>yviewpager</artifactId>
+  <version>0.2</version>
+  <type>pom</type>
+</dependency>
+```
+
+## 简介
+支持水平方向上滑动和竖直方向上的滑动，直接修改的官方提供的`ViewPager`的源码，注入了方向判断，使用起来和官方的`ViewPager`基本一样，还有监听事件也是一样的，支持`setOffscreenPageLimit()`可以放心滑动，以及`TabLayout`等。
+
+## 特性
+
+### 方向
+
+在官方原有特性下，新增加`direction`属性。可以通过两种方式来设置：
+
+#### xml
+
+```
+<cn.youngkaaa.yviewpager.YViewPager
+    android:id="@+id/viewpager"
+    android:layout_width="match_parent"
+    android:layout_height="match_parent"
+    app:orientation="vertical"/>
+```
+
+就像上面这样，只需要设置`app:orientation`属性，该属性可选值为:`vertical`和`horizontal`，分别代表竖直方向上滑动和水平方向上滑动。
+
+#### java代码
+
+```
+mViewPager.setDirection(YViewPager.VERTICAL);
+
+mViewPager.setDirection(YViewPager.HORIZONTAL);
+
+```
+
+具体意思同上
+注意，设计的起始是想着在`YViewPager`一开始inflate时就应该确定了方向，如果在后期app运行时（即在`YViewPager`创建显示后）通过代码来修改方向的话，这种做法不推荐，因为`YViewPager`内部可能有很深View结构的`Fragment`，所以在此时修改`YViewPager`的`direction`的话，会通知刷新`YViewPager`，会造成顿时卡顿，所以不推荐此做法，但是不代表不可以这样做，如果您的需求确实是这样那么这样做也是可以的。
+
+### 循环滚动
+
+在`v1.2`版本开始增添了`circulatory`属性，你可以这样使用：
+
+#### xml
+
+```
+<cn.youngkaaa.yviewpager.YViewPager
+  android:id="@+id/viewpager1"
+  android:layout_width="match_parent"
+  android:layout_height="188dp"
+  app:circulatory="true"
+  app:orientation="horizontal"/>
+```
+是的，就只需要一句代码就可以了。
+
+#### java
+
+对不起，暂时不支持使用java代码动态修改`circulatory`属性。因为一般循环与否都是在xml中提前决定好的，所以就仅仅支持xml修改
+
+## 版本
+
+
+### v0.2
+
+加入循环属性，同样支持水平和竖直两个方向上的循环。
+
+### v0.1
+
+支持水平和竖直方向上得滑动切换
+
+## 最后
+
+为什么我要在官方原有的`ViewPager`源码的基础上来修改，是因为官方在做`ViewPager`中做了很多优化和提升，所以我只修改了原有的源码的事件逻辑，并没有大的修改，所以官方的心血还是保留了的。但是这样带来的也有缺点，那就是官方的那些`FragmentPagerAdapter`和`FragmentStatePagerAdapter`以及`PagerAdapter`都不能直接调用了，因为这些类里面有一些方法不支持外部类调用，所以我拷贝了这三个类到本仓库中，代码和官方的是一样的，只是改了类名以保证可以在`YViewPager`中调用而已，所以你可以按照官方的方式来使用，你可以在你的项目中需要哪一个`XXXXAdapter`就拷贝该类到你的项目中去。
