У меня возникли проблемы с реализацией пользовательских getFilter в пользовательском массиве Adapter. На самом деле я понятия не имею, как это реализовать. Пробовал разные коды, но все равно не повезло. Вот мой собственный адаптер массива.

package com.test.FilterableList.Adapters;

import java.util.ArrayList;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;

import com.test.FilterableList.Models.ListTO;
import com.test.FilterableList.R;

import android.widget.Filterable;


public class FilterableAdapter extends ArrayAdapter implements Filterable {

    // declaring our ArrayList of items
    public ArrayList objects;

    /* here we must override the constructor for ArrayAdapter
    * the only variable we care about now is ArrayList objects,
    * because it is the list of objects we want to display.
    */
    public FilterableAdapter(Context context, int textViewResourceId, ArrayList objects) {
        super(context, textViewResourceId, objects);
        this.objects = objects;
    }

    /*
     * we are overriding the getView method here - this is what defines how each
     * list item will look.
     */
    public View getView(int position, View convertView, ViewGroup parent){

        // assign the view we are converting to a local variable
        View v = convertView;

        // first check to see if the view is null. if so, we have to inflate it.
        // to inflate it basically means to render, or show, the view.
        if (v == null) {
            LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            v = inflater.inflate(R.layout.list_item, null);
        }

        /*
         * Recall that the variable position is sent in as an argument to this method.
         * The variable simply refers to the position of the current object in the list. (The ArrayAdapter
         * iterates through the list we sent it)
         *
         * Therefore, i refers to the current Item object.
         */
        ListTO i = objects.get(position);

        if (i != null) {

            // This is how you obtain a reference to the TextViews.
            // These TextViews are created in the XML files we defined.

            TextView tt = (TextView) v.findViewById(R.id.list_name);
            if (tt != null){
                tt.setText(i.FileName);
            }



        }

        // the view must be returned to our activity
        return v;

    }
}

А вот и класс ListTO.

package com.test.FilterableList.Models;

public class ListTO {

    public int Id;
    public String FileName;
    public String FileUri;

    public ListTO(int id, String fileName, String fileUri) {

        Id = id;
        FileName = fileName;
        FileUri = fileUri;

    }

}

А вот и макет.

Здесь ключевое слово поиска происходит от "inputSearch» Редактировать текст.

Вот'S текст изменил слушателя.

 inputSearch.addTextChangedListener(new TextWatcher() {

                    @Override
                    public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
                        // When user changed the Text
                      //  Toast.makeText(getActivity(), cs.toString(), Toast.LENGTH_LONG).show();
                        m_adapter.getFilter().filter(cs);
                    }

                    @Override
                    public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
                                                  int arg3) {
                        // TODO Auto-generated method stub

                    }

                    @Override
                    public void afterTextChanged(Editable arg0) {
                        // TODO Auto-generated method stub
                    }
                });

Благодарю.
