AStickyHeader_ohos

本项目是基于开源项目AStickyHeader进行鸿蒙化的移植和开发的,可以通过项目标签以及github地址(https://github.com/DWorkS/AStickyHeader)追踪到原安卓项目版本。

项目介绍
  • 项目名称:AStickyHeader_ohos

  • 所属系列:鸿蒙的第三方组件适配移植

  • 功能:支持ListContainer的分组效果,支持给每一个分组添加标题,不支持分组标题栏滑动时置顶效果

  • 项目移植状态:80%,由于harmonyos缺少dispatchdraw的对应方法,导致不能实现置顶效果

  • 调用差异:将列表分组标题栏置顶的类名由 PinnedSectionListView 更改为 PinnedSectionListViewWrapper

  • 开发版本:sdk5,DevEco Studio3.0 Beta2

  • 项目发起作者:刘磊

  • 邮箱:792301176@qq.com

  • 原项目Doc地址:https://github.com/DWorkS/AStickyHeader

    • 分组列表布局标题栏

项目介绍
  • 编程语言:Java
  • 本项目为封装的第三方库,使用时需要将库导入项目。
安装教程
  1. 下载 jar 包 AStickyHeader.jar。 启动 DevEco Studio,将下载的jar包,导入工程目录“entry->libs”下。 在moudle级别下的build.gradle文件中添加依赖,在dependences标签中增加对libs目录下jar包的引用。
   dependencies {
       implementation fileTree(dir: 'libs', include: ['*.jar', '*.har'])
   	……
   }
  1. 在导入的jar包上点击右键,选择“Add as Library”对包进行引用,选择需要引用的模块,并点击“OK”即引用成功。
使用说明

这里以PinnedSectionListView为例

  1. 需要用到的主要资源
//定义一个标题栏置顶的列表
private PinnedSectionListViewWrapper list;
//自定义的内容项的BaseItemProvider
private ImageAdapter mAdapter;
//定义标题列表
private List<SimpleSectionedListAdapter.Section> sections = new ArrayList<>();
//图像资源id
private Integer[] mImageIds = {
    ResourceTable.Media_cat1, ResourceTable.Media_cat2, 
    ResourceTable.Media_cat3, ResourceTable.Media_cat4, 
    ResourceTable.Media_cat5, ..., 
    ResourceTable.Media_cat95, ResourceTable.Media_cat96, 
    ResourceTable.Media_cat97, ResourceTable.Media_cat98, 
    ResourceTable.Media_cat99, ResourceTable.Media_cat100,
};
//标题名字
private String[] mHeaderNames = { "Cute Cats", "Few Cats", "Some Cats", "Some More Cats", "Some More More Cats", "Many Cats", "Many Many Cats", "So Many Cats" };
//标题位置
private Integer[] mHeaderPositions = { 0, 6, 11, 37, 38, 60, 77, 89 };   

PinnedSectionGridView同理。需要将PinnedSectionListViewWrapper换为PinnedSectionGridView,List<SimpleSectionedListAdapter.Section>换为List<SimpleSectionedGridAdapter.Section>即可。

  1. 自定义的列表内容项 Provider
    private class ImageAdapter extends BaseItemProvider{

        private LayoutScatter mScatter;

        public ImageAdapter(Context context) {
            mScatter = LayoutScatter.getInstance(context);
        }

        @Override
        public int getCount() {
            return mImageIds.length;
        }

        @Override
        public Object getItem(int i) {
            return null;
        }

        @Override
        public long getItemId(int i) {
            return i;
        }

        @Override
        public Component getComponent(int i, Component component, ComponentContainer parent) {
            //将 图片和文字内容 与 component 绑定
            Image image;
            Text name;
            if (component == null) {
                component = mScatter.parse(ResourceTable.Layout_list_item, parent, false);
            }
            image = (Image) component.findComponentById(ResourceTable.Id_img_listItem_image);
            image.setPixelMap(mImageIds[i]);
            name = (Text) component.findComponentById(ResourceTable.Id_tx_listItem_text);
            name.setText("A Cute Cat"+(i+1));

            return component;
        }
    }

PinnedSectionGridView在实现列表内容项Provider与PinnedSectionListView相同。

  1. 布局及初始化

    3.1 xml布局

主页面布局:main_layout.xml

3.2 代码中使用布局并初始化

列表布局SimpleSectionedListAdapter的使用

/**
 * SimpleSectionedListAdapter 使用方法(需要自定义单项的 BaseItemProvider 或 直接使用 SimpleAdapter)
 * mAdapter 为实现 内容项 的 itemProvider
 * mHeaderPositions 为 需要添加置顶标题栏 的位置(内容项的坐标之前,从0开始)
 * mHeaderNames 为 需要添加置顶标题栏 的文字内容
 * 实例化 SimpleSectionedListAdapter,传入 标题栏的 layoutId 和 标题栏中Text组件的 textId
 * 将刚刚设置好的 sections 传入
 * 最后使用 setItemProvider 方法把 SimpleSectionedListAdapter 填入即可
 */

lc_list_list = (PinnedSectionListViewWrapper) findComponentById(ResourceTable.Id_lc_list_list);
//使用 ImageAdapter 作为 BaseItemProvider
mAdapter = new ImageAdapter(this);
//根据规定的 标题栏位置 创建 sections
for(int i = 0; i < mHeaderPositions.length; i++) {tions.add(new         				Section(mHeaderPositions[i], mHeaderNames[i]));
}
//初始化 simpleSectionedListAdapter
SimpleSectionedListAdapter simpleSectionedListAdapter  = new SimpleSectionedListAdapter(this, mAdapter,
ResourceTable.Layout_list_item_header, ResourceTable.Id_tx_listItemHeader_header);
//设置sections
simpleSectionedListAdapter.setSections(sections.toArray(new Section[0]));
//设置adapter
lc_list_list.setItemProvider(simpleSectionedListAdapter);

网格布局SimpleSectionedGridAdapter的使用

/**
 * SimpleSectionedGridAdapter 使用方法(需要自定义单项的 BaseItemProvider 或 直接使用 SimpleAdapter)
 * mAdapter 为实现 内容项 的 itemProvider
 * mHeaderPositions 为 需要添加置顶标题栏 的位置(内容项的坐标之前,从0开始)
 * mHeaderNames 为 需要添加置顶标题栏 的文字内容
 * 实例化 SimpleSectionedListAdapter,传入 标题栏的 layoutId 和 标题栏的根组件id 和 标题栏中Text组件的 textId
 * 将 GridView 对象和 simpleSectionedGridAdapter 绑定
 * 将刚刚设置好的 sections 传入
 * 最后使用 setItemProvider 方法把 SimpleSectionedListAdapter 填入即可
 */
tl_grid_grid = (GridView) findComponentById(ResourceTable.Id_tl_grid_grid);
//使用 ImageAdapter 作为 BaseItemProvider
mAdapter = new ImageAdapter(this);
//根据规定的 标题栏位置 创建 sections
for (int i = 0; i < mHeaderPositions.length; i++) {
sections.add(new Section(mHeaderPositions[i], mHeaderNames[i]));
//初始化 simpleSectionedGridAdapter
SimpleSectionedGridAdapter simpleSectionedGridAdapter = new SimpleSectionedGridAdapter(this, mAdapter,
ResourceTable.Layout_grid_item_header, ResourceTable.Id_dl_gridItemHeader, ResourceTable.Id_tx_gridItemHeader_header);
//绑定GridView
simpleSectionedGridAdapter.setGridView(tl_grid_grid);
//设置sections
simpleSectionedGridAdapter.setSections(sections.toArray(new Section[0]));
//设置adapter
tl_grid_grid.setItemProvider(simpleSectionedGridAdapter);
