問題_我想讓"See All Item"按鈕將數(shù)據(jù)從 RecyclerView 傳遞到另一個 RecyclerView 片段，它看起來像游戲商店，有按鈕"More"可以查看另一個片段中的所有項目AdapterSingleHotTrendingNews.javapublic class AdapterSingleHotTrendingNews extends RecyclerView.Adapter{private Context mContext;private ArrayList<ModelSingleHotTrendingNews> modelSingleHotTrendingNews;public AdapterSingleHotTrendingNews(Context mContext, ArrayList<ModelSingleHotTrendingNews> modelSingleHotTrendingNews) { this.mContext = mContext; this.modelSingleHotTrendingNews = modelSingleHotTrendingNews;}//Container@Overridepublic SingleHotTrendingNewsViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType) { View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.item_single_hottrendingnews, null); return new SingleHotTrendingNewsViewHolder(v);}//Fill Container with Model Setter Getter@Overridepublic void onBindViewHolder(RecyclerView.ViewHolder holder, final int position) { final SingleHotTrendingNewsViewHolder singleHotTrendingNewsViewHolder = (SingleHotTrendingNewsViewHolder) holder; final ModelSingleHotTrendingNews modelSingleHotTrendingNewsX = modelSingleHotTrendingNews.get(position); //Set singleHotTrendingNewsViewHolder.TVGameDate.setText(modelSingleHotTrendingNewsX.getGamedate()); singleHotTrendingNewsViewHolder.TVGameDescription.setText(modelSingleHotTrendingNewsX.getGamedescription()); singleHotTrendingNewsViewHolder.IMGGameImage.setImageResource(modelSingleHotTrendingNewsX.getGameimage());

從第一個適配器onClick，調(diào)用第二個適配器并更新 RecyclerView

sectionHotTrendingNewsViewHolder.BTNHotTrendingNewsMore.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View v) {

sectionHotTrendingNewsViewHolder.RecyclerViewSectionHotTrendingNews.setAdapter( new AdapterSingleHotTrendingNews(v.getContext(), modelSectionHotTrendingNews.get(position).getAllItemsInSection()))

}

});

或者，如果您想在其他活動中顯示此更多新聞。然后執(zhí)行以下操作：

像這樣創(chuàng)建ModelSingleHotTrendingNews類：Serializable
公共類 ModelSingleHotTrendingNews 實現(xiàn) Serialized { ... }
改變onClick
sectionHotTrendingNewsViewHolder.BTNHotTrendingNewsMore.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Intent Intent = new Intent(mContext, TabMoreHotActivity.class); Intent().putExtra("MoreNews", modelSectionHotTrendingNews.get(位置).getAllItemsInSection()) mContext.startActivity(intent); } });
TabMoreHotActivity使用 ArrayList 而不是ArrayList<ModelSectionHotTrendingNews>

希望對你有幫助。你把你的代碼弄亂了:(
