如有使用方面的问题或者交流请加QQ群：494648687
例
1.简单的显示（显示一种布局）
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;
}
}
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;
}
}
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());
}
}
效果1：
![]()
2.简单的显示（显示多种布局）
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;
}
}
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;
}
}
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());
}
}
效果2：
![]()
![]()
3.嵌套ListContainer
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);
}
}
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;
}
}
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);
}
}
效果3：
![]()
![]()
4.ItemView中的按钮点击，等事件
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;
}
}

/*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;
}
}
- 文件PlayListItemViewHolder.java

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");
}
}
效果4：

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));
