超过 1 个回收站的 SearchView

Question

您好，我有一个带有 7 个标签 的 view pager，所有标签里面都有一个 recyclerview 我想为所有标签添加搜索. 我试图将它们全部添加到一个回收器视图中进行搜索，但我真的不知道该怎么做。 任何人都可以给我一些提示如何做到这一点？ 我想在我的代码中添加一个搜索对话框和一个包含我所有项目的单个回收器视图，这可能吗？ 而且我所有的 recyclerViews 都有自己的 Adapter 和 Parser 和 Model，它们都彼此不同

代码如下：

RecyclerView 适配器类：

public class SearchAdapter extends RecyclerView.Adapter<SearchAdapter.SearchViewHolder> {


public SearchAdapter(Context context,int code) {
    this.code = code;
    this.context = context;
}
private Context context;
private int code;
private View view;
@Override
public SearchViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    switch (code){
        case 1:
            view = LayoutInflater.from(parent.getContext()).inflate(R.layout.recycler_item,parent,false);
            return new SearchViewHolder(view);
        case 2:
            view = LayoutInflater.from(parent.getContext()).inflate(R.layout.news_layout,parent,false);
            return new SearchViewHolder(view);
        case 3:
            view = LayoutInflater.from(parent.getContext()).inflate(R.layout.last_world_memes_list_item,parent,false);
            return new SearchViewHolder(view);
        case 4:
            view = LayoutInflater.from(parent.getContext()).inflate(R.layout.ex_list_tours_child,parent,false);
            return new SearchViewHolder(view);
        case 5:
            view = LayoutInflater.from(parent.getContext()).inflate(R.layout.last_url_view,parent,false);
            return new SearchViewHolder(view);
        case 6:
            view = LayoutInflater.from(parent.getContext()).inflate(R.layout.twitch,parent,false);
            return new SearchViewHolder(view);
    }
    return new SearchViewHolder(view);
}

@Override
public void onBindViewHolder(SearchViewHolder holder, int position) {
    switch (code){
        case 1:

    }
}

@Override
public int getItemCount() {
    return 0;
}

Answer 1

在这里，您为所有不同的RecyclerView 使用了 7 个不同的pojo 类。如果您想按单个 searchView 搜索，则必须将所有 pojo 数据添加到单个 pojo 类。但是，如果您将所有数据添加到单个 pojo 搜索时会出现结果，但是您很难找到该片段。

如果您只需要该 viewPager 片段的结果。然后，您必须为所有 pojo 类实现相同的 searchView，并且您必须仅在该 fragment 上获得结果。
