Question

我将autoCompleteTextView与customLayout和Adapter一起使用，但是问题是当我们在建议中单击某个项目时，既不会在autoCompleteTextView中填充项目值，也不会触发OnItemClickListener。

代码使用在autoCompleteTextView中输入的文本过滤建议，但onClick事件未发生任何事情。

下面是我的代码

TeamSuggestionAdapter.java文件

package com.material.ipladmin;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.Filter;
import android.widget.Filterable;
import android.widget.LinearLayout;
import android.widget.TextView;

import com.bumptech.glide.Glide;

import java.util.ArrayList;
import java.util.List;

import de.hdodenhof.circleimageview.CircleImageView;




public class TeamsSuggestionAdapter extends ArrayAdapter<Team> implements Filterable {

    private Context context;

    private List<Team> allTeams;

    private List<Team> teams;

    private ListFilter listFilter = new ListFilter();


    public TeamsSuggestionAdapter(Context context, List<Team> teams) {
        super(context, 0, teams);
        this.context = context;
        this.allTeams = teams;

    }

    @Override
    public int getCount() {
        return allTeams.size();
    }

    @Override
    public Team getItem(int i) {
        return allTeams.get(i);
    }

    @Override
    public long getItemId(int i) {
        return 0;
    }

    @Override
    public View getView(int i, View view, ViewGroup viewGroup) {

        if(view == null) {
            view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.add_match_suggestions_layout, viewGroup, false);
        }

        CircleImageView logo = view.findViewById(R.id.suggestionItemlogoImage);
        TextView name = view.findViewById(R.id.suggestionItemName);
        LinearLayout linearLayout = view.findViewById(R.id.addMatchSuggestionsLinearLayout);

        Team team = getItem(i);

        Glide.with(context).load(team.logo).into(logo);
        name.setText(team.teamName);
        linearLayout.setTag(team.teamId);

        return view;
    }

    @Override
    public Filter getFilter() {
        return listFilter;
    }


    class ListFilter extends Filter {

        private Object lock = new Object();


        @Override
        protected FilterResults performFiltering(CharSequence prefix) {

            FilterResults results = new FilterResults();

            if(teams == null) {
                synchronized (lock) {
                    teams = new ArrayList<>(allTeams);
                }
            }

            if (prefix == null || prefix.length() <= 0) {

                synchronized (lock) {
                    results.values = teams;
                    results.count = teams.size();
                }

            }
            else
            {

                String searchThis = prefix.toString().toLowerCase();

                List<Team> searched = new ArrayList<>();

                for (int i=0; i<teams.size(); i++) {

                    if (teams.get(i).teamName.toLowerCase().contains(searchThis)) {
                        searched.add(teams.get(i));
                    }

                }

                results.values = searched;
                results.count = searched.size();

            }

            return results;
        }

        @Override
        protected void publishResults(CharSequence charSequence, FilterResults results) {

            if (results.values != null) {

                allTeams = (ArrayList<Team>) results.values;

            } else {

                allTeams = null;

            }

            if (results.count > 0 ) {
                notifyDataSetChanged();
            }
            else {
                notifyDataSetInvalidated();
            }
        }

        @Override
        public CharSequence convertResultToString(Object resultValue) {
            return ((Team) resultValue).teamId;
        }
    }

}

add_match_suggestions_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:padding="5dp"
    android:clickable="true"
    android:focusable="true"
    android:id="@+id/addMatchSuggestionsLinearLayout">

    <de.hdodenhof.circleimageview.CircleImageView
        android:layout_width="40dp"
        android:layout_height="40dp"
        android:id="@+id/suggestionItemlogoImage"
        android:src="@drawable/default_team_logo"
        android:layout_gravity="center"/>

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:padding="10dp"
        android:id="@+id/suggestionItemName"
        android:textColor="@color/colorBlack"
        android:textSize="10sp"
        android:text="Suggestion Item name"/>

</LinearLayout>

MainActivity.java

TeamsSuggestionAdapter TeamsAdapter = new TeamsSuggestionAdapter(this, teams);

        autoCompleteTextView.setAdapter(TeamsAdapter);

        autoCompleteTextView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {

                Toast.makeText(AddMatchActivity.this, "Item Clicked", Toast.LENGTH_SHORT).show();

            }
        });

Answer 1

在android:descendantFocusability="blocksDescendants"的LinearLayout中添加add_match_suggestions_layout.xml并从其中删除focusable和clickable，解决了这个问题。

OnItemClickListener不能与AutoCompleteTextView一起使用
