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());
}
}
效果1：
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);
}
}
