我想通过RecyclerView搜索,我有List< BaSEOfCards> (BaSEOfCards是我的getter& setter类)
我的RecyclerViewAdapter：
我的RecyclerViewAdapter：
public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.MyViewHolder> {
private LayoutInflater inflater;
private List<BaSEOfCards> items;
//private int itemLayout;
//String cardvalue;
private Activity mActivity;
public RecyclerViewAdapter(Activity mActivity,Context context,List<BaSEOfCards> items) {
this.mActivity = mActivity;
inflater = LayoutInflater.from(context);
this.items = items;
//this.itemLayout = itemLayout;
}
@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent,int viewType) {
View view = inflater.inflate(R.layout.custom_row,parent,false);
MyViewHolder holder = new MyViewHolder(view,mActivity);
return holder;
}
@Override
public void onBindViewHolder(MyViewHolder holder,int position) {
BaSEOfCards item = items.get(position);
holder.title.setTag(item);
holder.title.setText(item.getCardName());
}
@Override
public int getItemCount() {
return items.size();
}
public static class MyViewHolder extends RecyclerView.ViewHolder {
private Activity mActivity;
TextView title;
ImageView titileImageView;
public MyViewHolder(View itemView,Activity mActivity) {
super(itemView);
titileImageView = (ImageView) itemView.findViewById(R.id.image_country);
title = (TextView) itemView.findViewById(R.id.listText);
this.mActivity = mActivity;
}
}
}
我将SearchView添加到我的菜单中并在MainActivity中初始化它：
MenuItem menuItem = menu.findItem(R.id.action_search1);
searchView = (SearchView) MenuItemCompat.getActionView(menuItem);
SearchManager manager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
searchView.setIconifiedByDefault(true);
接下来我需要做什么？让我的RecyclerViewAdapter实现Filterable或者什么？或者只是在* RecyclerViewAdapter **中进行类过滤,然后从我的MainActivity中调用它？
解决方法
我解决了我的问题
>让我的类RecyclerViewAdapter实现Filterable
>添加行私有列表< BaSEOfCards>原稿;
>在RecyclerViewAdapter中添加方法getFilter
public Filter getFilter() {
return new Filter() {
@Override
protected FilterResults performFiltering(CharSequence constraint) {
final FilterResults oReturn = new FilterResults();
final List<BaSEOfCards> results = new ArrayList<BaSEOfCards>();
if (orig == null)
orig = items;
if (constraint != null){
if(orig !=null & orig.size()>0 ){
for ( final BaSEOfCards g :orig) {
if (g.getCardName().toLowerCase().contains(constraint.toString()))results.add(g);
}
}
oReturn.values = results;
}
return oReturn;
}
@Override
protected void publishResults(CharSequence constraint,FilterResults results) {
items = (ArrayList<BaSEOfCards>)results.values;
notifyDataSetChanged();
}
};
>使MainActivity实现SearchView.OnQueryTextListener并更改onTextTextChange方法：
@Override
public boolean onQueryTextChange(String newText) {
if ( TextUtils.isEmpty ( newText ) ) {
adapter.getFilter().filter("");
} else {
adapter.getFilter().filter(newText.toString());
}
return true;
}
