例

1.简单的显示（显示一种布局）

文件SongSlice.java

public class SongSlice extends AbilitySlice { private ListContainer listContainer; @Override protected void onStart(Intent intent) { super.onStart(intent); super.setUIContent(ResourceTable.Layout_ability_song); listContainer = (ListContainer) findComponentById(ResourceTable.Id_listContainer); listContainer.setItemProvider(new UltimateProvider(getSongs(),getContext())); } List getSongs(){ List list = new ArrayList(); for (int i=0; i<100; i++) { list.add(new SongModel("歌曲名称："+i,"歌手："+i)); } return list; } }

文件SongModel.java模型

public class SongModel implements Model { private String name; private String singer; @Override public int getResources(int position) { return ResourceTable.Layout_song_item; } @Override public Class getHolderClass(int position) { return SongViewHolder.class; } }

文件SongViewHolder.java模型

public class SongViewHolder extends ViewHolder<SongModel> { private Image icon; private Text songName; private Text songer; public SongViewHolder(EventTransmissionListener eventTransmissionListener, Component component, UltimateProvider provider) { super(eventTransmissionListener, component,provider); icon = (Image) findComponentById(ResourceTable.Id_icon); songName = (Text) findComponentById(ResourceTable.Id_songName); songer = (Text) findComponentById(ResourceTable.Id_songer); } @Override public void onDataBound() { songName.setText(getModel().getName()); songer.setText(getModel().getSinger()); } }

2.简单的显示（显示多种布局）

RecommendSlice.java

public class RecommendSlice extends AbilitySlice { private ListContainer listContainer; @Override protected void onStart(Intent intent) { super.onStart(intent); super.setUIContent(ResourceTable.Layout_ability_recommend); listContainer = (ListContainer) findComponentById(ResourceTable.Id_listContainer); listContainer.setItemProvider(new UltimateProvider<Model>(getData(),getContext())); } List getData(){ List list = new ArrayList(); for (int i=0; i<100; i++) { if (i %2 == 0) { list.add(new SongModel("歌曲名称："+i,"歌手名称:"+i)); } else { list.add(new AlbumModel("专辑名称："+i,"歌手")); } } return list; } }

文件AlbumModel.java模型

public class AlbumModel implements Model { private String name; private String songer; @Override public int getResources(int position) { return ResourceTable.Layout_album_item; } @Override public Class getHolderClass(int position) { return AlbumViewHolder.class; } }

文件AlbumViewHolder.java

public class AlbumViewHolder extends ViewHolder<AlbumModel> { private Text name; private Text songer; public AlbumViewHolder(EventTransmissionListener eventTransmissionListener, Component component, UltimateProvider provider) { super(eventTransmissionListener, component,provider); name = (Text) findComponentById(ResourceTable.Id_name); songer = (Text) findComponentById(ResourceTable.Id_songer); } @Override public void onDataBound() { name.setText(getModel().getName()); songer.setText(getModel().getSonger()); } }

3.嵌套ListContainer

NestedListAbility.java

public class NestedListSlice extends AbilitySlice { private ListContainer listContainer; @Override protected void onStart(Intent intent) { super.onStart(intent); super.setUIContent(ResourceTable.Layout_ability_nested_list); listContainer = (ListContainer) findComponentById(ResourceTable.Id_listContainer); listContainer.setItemProvider(new UltimateProvider<Model>(getData(), getContext())); } List getData() { List list = new ArrayList(); for (int i=0; i<100; i++) { if (i%5 == 0) { list.add(new SongModel("歌曲名称："+i,"歌手："+i)); } else if (i%5 == 1) { list.add(new AlbumModel("推荐专辑："+i,"歌手："+i)); } else if (i%5 == 2) { list.add(creageMusicData(i,i%2)); } else { list.add(creageHybridData()); } } return list; } /*创建推荐内容*/ MusicModel creageMusicData(int position,int type){ List list = new ArrayList(); String title = type == 0 ? "推荐歌曲":"推荐专辑"; for (int i=0; i< 100; i++) { if (type == 0) { list.add(new NestedSongModel("推荐歌曲："+i,"歌手："+i)); } else if(type == 1){ list.add(new NestedAlbumModel("推荐专辑："+i,"歌手："+i)); } } return new MusicModel(title + position,list); } /*创建推荐内容*/ MusicModel creageHybridData(){ List list = new ArrayList(); for (int i=0; i< 100; i++) { if (i %2 == 0) { list.add(new NestedSongModel("推荐歌曲："+i,"歌手："+i)); } else { list.add(new NestedAlbumModel("推荐专辑："+i,"歌手："+i)); } } return new MusicModel("推荐的歌曲+专辑",list); } }

文件MusicModel.java模型

public class MusicModel implements Model { private String title; private List data; @Override public int getResources(int position) { return ResourceTable.Layout_music_item; } @Override public Class getHolderClass(int position) { return MusicViewHolder.class; } }

文件MusicViewHolder.java

public class MusicViewHolder extends ViewHolder<MusicModel> { private Text title; private ListContainer listContainer; private UltimateProvider ultimateProvider; public MusicViewHolder(EventTransmissionListener eventTransmissionListener, Component component,UltimateProvider provider) { super(eventTransmissionListener, component,provider); title = (Text) findComponentById(ResourceTable.Id_title); listContainer = (ListContainer) findComponentById(ResourceTable.Id_listContainer); ultimateProvider = new UltimateProvider(null,getContext()); } @Override public void onDataBound() { title.setText(getModel().getTitle()); ultimateProvider.setModels(getModel().getData()); listContainer.setItemProvider(ultimateProvider); } }

4.ItemView中的按钮点击，等事件

EventHanlderAbility.java

public class EventHanlderSlice extends AbilitySlice { private ListContainer listContainer; static final HiLogLabel label = new HiLogLabel(HiLog.LOG_APP, 0x00201, "MY_TAG"); @Override protected void onStart(Intent intent) { super.onStart(intent); super.setUIContent(ResourceTable.Layout_ability_event_hanlder); listContainer = (ListContainer) findComponentById(ResourceTable.Id_listContainer); UltimateProvider ultimateProvider = new UltimateProvider<Model>(getData(), getContext()); listContainer.setItemProvider(ultimateProvider); /*这里使用匿名内部类实现，也可以让Slice实现接口EventTransmissionListener*/ ultimateProvider.setEventTransmissionListener(new EventTransmissionListener() { @Override public Object onEventTransmission(Object target, Object params, int eventId, CallBack callBack) { if (target instanceof PlayListItemViewHolder){ if (eventId == 1) {//播放列表中播放被点击，演示同步返回数据 return handlePlayStatus(target,params,eventId,callBack); } else if(eventId == 2){//收藏 return handleCollectionStatus(target,params,eventId,callBack); } } return null; } }); } /*处理ItemView中的播放音乐的状态(演示同步返回数据)*/ public Object handlePlayStatus(Object target, Object params, int eventId, EventTransmissionListener.CallBack callBack) { boolean playStatus = (boolean) params; return !playStatus;//更改播放状态返回 } /*处理ItemView中的播放音乐的状态(演示异步返回数据)*/ public Object handleCollectionStatus(Object target, Object params, int eventId, EventTransmissionListener.CallBack callBack) { boolean collectionStatus = (boolean) params; /*这里可以做一些耗时的操作，比如将是否收藏当前音乐发送给服务器，服务器返回结果后再通过callBack回掉到列表中更新状态*/ /*耗时操作省略*/ callBack.callBack(!collectionStatus);//使用异步返回 return null; } /*构造数据*/ public List getData(){ List list = new ArrayList(); for (int i=0; i<100; i++) { list.add(new PlayListItemModel("歌曲名称："+i,"歌手名字："+i)); } return list; } }

文件PlayListItemModel.java模型

public class PlayListItemModel implements Model { /*歌曲名称*/ private String name; /*歌手*/ private String songer; /*是否喜欢*/ private boolean love = false; /*是否收藏*/ private boolean collection = false; /*是否正在播放*/ private boolean play = false; @Override public int getResources(int position) { return ResourceTable.Layout_play_list_item; } @Override public Class getHolderClass(int position) { return PlayListItemViewHolder.class; } }

public class PlayListItemViewHolder extends ViewHolder<PlayListItemModel> { private Image icon; private Text name; private Text songer; private Text love; private Text collection; private Text play; public PlayListItemViewHolder(EventTransmissionListener eventTransmissionListener, Component component,UltimateProvider provider) { super(eventTransmissionListener, component,provider); icon = (Image) findComponentById(ResourceTable.Id_icon); name = (Text) findComponentById(ResourceTable.Id_name); songer = (Text) findComponentById(ResourceTable.Id_songer); love = (Text) findComponentById(ResourceTable.Id_love); collection = (Text) findComponentById(ResourceTable.Id_collection); play = (Text) findComponentById(ResourceTable.Id_play); love.setClickedListener(new Component.ClickedListener() { @Override public void onClick(Component component) { //内容处理点击事件 getModel().setLove(!getModel().isLove());//这里把状态存储在数据中，可以根据需求将状态存储在provider中的自定义数据中。具体使用方式可以查看CustomData的使用 notifyCurrentDataSetItemChanged(); } }); play.setClickedListener(new Component.ClickedListener() { @Override public void onClick(Component component) { //将事件传递到Slice中然后同步返回结果 boolean play = (boolean) getEventTransmissionListener().onEventTransmission(PlayListItemViewHolder.this, getModel().isPlay(),1,null); getModel().setPlay(play);//这里把状态存储在数据中，可以根据需求将状态存储在provider中的自定义数据中。具体使用方式可以查看CustomData的使用 notifyCurrentDataSetItemChanged(); } }); collection.setClickedListener(new Component.ClickedListener() { @Override public void onClick(Component component) { //此次演示异步返回数据更新状态 getEventTransmissionListener().onEventTransmission(PlayListItemViewHolder.this, getModel().isCollection(), 2, new EventTransmissionListener.CallBack() { @Override public Object callBack(Object object) { boolean collection = (boolean) object;//这里activity中应该返回boolean类型以适合这里需要的数据 getModel().setCollection(collection);//这里把状态存储在数据中，可以根据需求将状态存储在provider中的自定义数据中。具体使用方式可以查看CustomData的使用 notifyCurrentDataSetItemChanged(); return null; } }); } }); } @Override public void onDataBound() { name.setText(getModel().getName()); songer.setText(getModel().getSonger()); // 为了节约时间 以下状态使用文字代替图片。 love.setText(getModel().isLove() ? "喜欢":"未喜欢"); collection.setText(getModel().isCollection() ? "收藏":"未收藏"); play.setText(getModel().isPlay() ? "播放":"未播放"); } }

5.ItemView中的按钮点击，等事件

CustomDataUserAbility.java

public class CustomDataUserSlice extends AbilitySlice implements EventTransmissionListener{ private ListContainer listContainer; private UltimateProvider ultimateProvider; private LoginData loginData = new LoginData();//用于存放用户名及密码 @Override protected void onStart(Intent intent) { super.onStart(intent); super.setUIContent(ResourceTable.Layout_ability_custom_data_use); listContainer = (ListContainer) findComponentById(ResourceTable.Id_listContainer); ultimateProvider = new UltimateProvider(getAllView(),getContext()); listContainer.setItemProvider(ultimateProvider); ultimateProvider.setCustomData(loginData);//演示设置自定义数据，这里主要记录输入的用户名和密码 ultimateProvider.setEventTransmissionListener(this); } /** * 同时显示登录和身份证验证界面 * @return */ public List getAllView() { List list = new ArrayList(); list.add(new OneTitleModel("登录")); list.add(new InputBoxModel("用户名：","","请输入用户名",false)); list.add(new InputBoxModel("密码：","","请输入密码",true)); list.add(new SubmitBtnModel("登录")); return list; } @Override public Object onEventTransmission(Object target, Object params, int eventId, CallBack callBack) { return null; } }
