edittextのListViewフィルタデータ

Question

私はcustomize adapterを使ってlistviewを作成しました。私はedittextを入力してリストビューをフィルタリングしたいと思います。しかし、私はFirebaseからすべてのデータを取得するため、難しいと感じました。どのようにデータを名前でフィルタリングできますか？どのコードを追加する必要がありますか？

それはPlzをこの.Ur実行するコードを追加しようとそれは

public class shopListAdapter extends ArrayAdapter<Shop> { 

private ArrayList<Shop> shops; 
Filter filter; 

public shopListAdapter(Context context, ArrayList<Shop> shops) { 
    super(context, 0, shops); 

} 

@Override 
public View getView(int position, View convertView, ViewGroup parent) { 

    Shop shops = getItem(position); 

    if (convertView == null) { 
     convertView = LayoutInflater.from(getContext()).inflate(R.layout.item, parent, false); 
    } 

    TextView name = (TextView) convertView.findViewById(R.id.txtName); 
    TextView address = (TextView) convertView.findViewById(R.id.txtAdd); 

    name.setText(shops.getShopName()); 
    address.setText(shops.getAddress()); 


    return convertView; 
}

私のアダプタクラスである私の主な活動

private void readFirebaseData() { 
    FirebaseDatabase.getInstance().getReference("account").addListenerForSingleValueEvent(new ValueEventListener() { 
     @Override 
     public void onDataChange(DataSnapshot dataSnapshot) { 
      for (DataSnapshot snapshot : dataSnapshot.getChildren()) { 
       uid = (String) snapshot.child("uid").getValue(); 
       contactNo = (String) snapshot.child("contactNo").getValue(); 

       email = (String) snapshot.child("email").getValue(); 
       name = (String) snapshot.child("name").getValue(); 

       Shop shops = new Shop(uid, contactNo, email, name); 
       shopListAdapter adapter = new shopListAdapter(getActivity(), shop); 
       adapter.add(shops); 


       listView.setAdapter(adapter); 
       adapter.notifyDataSetChanged(); 
      } 
     } 



} 
private void filter() { 
    searcher.addTextChangedListener(new TextWatcher() { 
     @Override 
     public void beforeTextChanged(CharSequence s, int start, int count, int after) { 

     } 

     @Override 
     public void onTextChanged(CharSequence s, int start, int before, int count) { 
      adapter.getFilter().filter(s); 
     } 

     @Override 
     public void afterTextChanged(Editable s) { 

     } 
    }); 
} 

では

public class MyLeadsAdapter extends ArrayAdapter<MyleadsListModel> { 

private Vector<MyleadsListModel> originalList; 
private Vector<MyleadsListModel> numberList; 
private CountryFilter filter; 
private Context context; 
public MyLeadsAdapter(Context context, int textViewResourceId, Vector<MyleadsListModel> numberList) { 
    super(context, textViewResourceId, numberList); 
    this.context = context; 
    this.numberList = new Vector<MyleadsListModel>(); 
    this.numberList.addAll(numberList); 
    this.originalList = new Vector<MyleadsListModel>(); 
    this.originalList.addAll(numberList); 
} 

@Override 
public Filter getFilter() { 
    if (filter == null) { 
     filter = new CountryFilter(); 
    } 
    return filter; 
} 


@Override 
public View getView(final int position, View convertView, 
        ViewGroup parent) { 

    // TODO Auto-generated method stub 
    final MyViewHolder mViewHolder; 

    LayoutInflater mInflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE); 

    if (convertView == null) { 
     convertView = mInflater.inflate(R.layout.row_my_leads, 
       null); 

     convertView.setTag(mViewHolder); 

    } else { 
     mViewHolder = (MyViewHolder) convertView.getTag(); 
    } 



    return convertView; 

} 

class MyViewHolder { 

} 

private class CountryFilter extends Filter { 

    @Override 
    protected FilterResults performFiltering(CharSequence constraint) { 

     constraint = constraint.toString().toLowerCase(); 
     FilterResults result = new FilterResults(); 
     if (constraint != null && constraint.toString().length() > 0) { 
      Vector<MyleadsListModel> filteredItems = new Vector<MyleadsListModel>(); 

      for (int i = 0, l = originalList.size(); i < l; i++) { 
       MyleadsListModel contactList = originalList.get(i); 
       if (contactList.getName().toString().toLowerCase() 
         .contains(constraint)) 
        filteredItems.add(contactList); 
      } 
      result.count = filteredItems.size(); 
      result.values = filteredItems; 
     } else { 
      synchronized (this) { 
       result.values = originalList; 
       result.count = originalList.size(); 
      } 
     } 
     return result; 
    } 

    @SuppressWarnings("unchecked") 
    @Override 
    protected void publishResults(CharSequence constraint, 
            FilterResults results) { 
     numberList = (Vector<MyleadsListModel>) results.values; 
     notifyDataSetChanged(); 
     clear(); 
     for (int i = 0, l = numberList.size(); i < l; i++) 
      add(numberList.get(i)); 
     notifyDataSetInvalidated(); 
    } 
} 

}

間違っ代です

このコードを追加Edittextの場合：

searcher.addTextChangedListener(new TextWatcher() { 
    @Override 
    public void beforeTextChanged(CharSequence s, int start, int count, int after) { 

    } 

    @Override 
    public void onTextChanged(CharSequence s, int start, int before, int count) { 
     adapter.getFilter().filter(s); 
    } 

    @Override 
    public void afterTextChanged(Editable s) { 

    } 
});
