CycleViewPager

支持自动轮播和循环滚动的ViewPager

Maven Central

系统要求

android 4.0(含)以上,Demo地址:https://github.com/androiddevelop/CycleViewPager/raw/master/cycle-view-pager-example-debug.apk

快速使用

1. 导入CycleViewPager项目

 compile 'me.codeboy.android:cycle-view-pager:2.0.0'

2. 在layout中引入me.codeboy.android.cycleviewpager.CycleViewPager这个View

  <me.codeboy.android.cycleviewpager.CycleViewPager
      android:id="@+id/cycleViewPager"
      android:layout_width="match_parent"
      android:layout_height="match_parent"/>

3. views创建

// 需要循环的创建方式
 List<View> views = new ArrayList<View>();

views.add(ViewFactory.create("最后一个view"));
for (int i = 0; i < 4; i++) {
    views.add(ViewFactory.create("第i个view");
}
views.add(ViewFactory.create("第一个view"));

 // 不需要循环的创建方式
 List<View> views = new ArrayList<View>();

 for (int i = 0; i < 4; i++) {
     views.add(ViewFactory.create("第i个view");
 }

4. 设置CycleViewPager的views以及滚动与轮播属性

CycleViewPager cycleViewPager = (CycleViewPager)mContext.findFragmentById(R.id.cycleViewPager);


//以下setData参数含义:
//1: 试图 2: 循环(默认true) 3: 轮播(默认false) 4: 轮播时间(默认5000ms)

//循环+轮播,3000ms自动切换
cycleViewPager.setData(views, true, true, 3000);

//只循环,不轮播
cycleViewPager.setData(views, true, false);
cycleViewPager.setData(views, true);
cycleViewPager.setData(views);

//与viewPager相同
cycleViewPager.setData(views, false);

setData请放在最后一步设置。

例子

项目中给出了6个例子,可以直接运行项目或者下载项目中得apk进行查看效果

1. NoCycleTextView

没有滚动的CycleTextView,与ViewPager相同

2. CycleTextView

可以滚动的CycleTextView

3. WheelCycleTextView

可以滚动与自动切换的CycleTextView

4. EventCycleTextView

监听CycleTextView滚动事件和view的点击事件

5. IndicatorCustom1CycleTextView

指示器的颜色、形状、位置的简单变化

6. IndicatorCustom2CycleTextView

自定义的指示器

7. NestedCycleTextView

CycleTextView嵌套在ViewPager中,实现滚动CycleTextView时外层ViewPager不滚动

注意事项

  • 外层有viewPager时,需要继承me.codeboy.android.cycleviewpager.BaseViewPager。
  • 设置自动播放时,CycleViewPager自动为可循环滚动.滚动是轮播的基础。
  • 自定义指示器时,获取的指示器容器的margin和padding都是0,需要自行根据需要设置。
  • 控件的点击事件请自行设置,多增加的第一个和最后一个控件由于动画时间也请设置事件。CycleViewPager仅提供循环和轮播的机制。
  • 使用中可以忽略添加的两个控件,listener中返回的position为处理后的位置。如果有4个view,名字为view0、view1、view2、view3,设置循环时,传入的views为view3'、view0、view1、view2、view3、view1',返回的position将介于[0,3]之间。
