### 安装教程

**1)** 在项目根目录下的build.gradle文件中，

```
allprojects {
     repositories {
         maven {
             url 'https://s01.oss.sonatype.org/content/repositories/releases/'
         }
     }
   }
```
**2)** 在entry模块的build.gradle文件中，
```
dependencies {
      implementation('com.gitee.chinasoft_ohos:autoScrollViewPager:1.0.0')
      ......  
   }
```
在sdk6，DevEco Studio2.2 Beta1下项目可直接运行 如无法运行，删除项目.gradle,.idea,build,gradle,build.gradle文件， 并依据自己的版本创建新项目，将新项目的对应文件复制到根目录下

### 使用说明
初始化ViewPager设置属性，功能实现。
```java
AutoScrollViewPager pager = (AutoScrollViewPager) component.findComponentById(ResourceTable.Id_scroll_pager);
final Text title = (Text) component.findComponentById(ResourceTable.Id_title);
ViewPagerIndicator indicator = (ViewPagerIndicator) component.findComponentById(ResourceTable.Id_indicator);
pager.addPageChangedListener(new PageSlider.PageChangedListener() {
            @Override
            public void onPageSliding(int i, float v, int i1) {

            }

            @Override
            public void onPageSlideStateChanged(int i) {

            }

            @Override
            public void onPageChosen(int i) {
                title.setText(titles[i]);
            }
        });

        pager.setProvider(new PageSliderProvider() {
            @Override
            public int getCount() {
                return imgs.length;
            }

            @Override
            public Object createPageInContainer(ComponentContainer componentContainer, int position) {
                Image view = new Image(componentContainer.getContext());
                ComponentContainer.LayoutConfig config = new ComponentContainer.LayoutConfig();
                config.width = ComponentContainer.LayoutConfig.MATCH_PARENT;
                config.height = ComponentContainer.LayoutConfig.MATCH_PARENT;
                view.setLayoutConfig(config);
                view.setScaleMode(Image.ScaleMode.CLIP_CENTER);
                view.setPixelMap(imgs[position]);
                componentContainer.addComponent(view);
                return view;
            }

            @Override
            public void destroyPageFromContainer(ComponentContainer componentContainer, int i, Object o) {
                componentContainer.removeComponent((Component) o);
            }

            @Override
            public boolean isPageMatchToObject(Component component, Object o) {
                return component == o;
            }
        });
        pager.setScrollFactor(5);
        pager.setPageCacheSize(4);
        pager.startAutoScroll(2000);
        pager.setOnPageClickListener(new AutoScrollViewPager.OnPageClickListener() {

            @Override
            public void onPageClick(AutoScrollViewPager autoScrollPager, int position) {
                if (toast != null) {
                    toast.cancel();
                    toast = null;
                }
                toast = new ToastDialog(context);
                toastView = (DependentLayout) LayoutScatter.getInstance(getFractionAbility()).parse(ResourceTable.Layout_faction_toast, null, false);
                toastText = (Text) toastView.findComponentById(ResourceTable.Id_text);
                toastText.setText("You clicked page: " + (position + 1));
                toast.setComponent(toastView);
                toast.setSize(DirectionalLayout.LayoutConfig.MATCH_CONTENT, DirectionalLayout.LayoutConfig.MATCH_CONTENT);
                toast.setTransparent(true);
                toast.setOffset(0, 100);
                toast.show();
            }
        });
        indicator.setOnIndicatorClickListener(new ViewPagerIndicator.OnIndicatorClickListener() {
            @Override
            public void onClik(int pos) {
                pager.setCurrentPage(pos);
            }
        });
        indicator.setViewPager(pager);
```
