SetOnItemClickListener on ListView of custom object not working?

Question

I define this layout:

<?xml version="1.0" encoding="utf-8"?> <androidx.constraintlayout.widget.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:orientation="vertical"
    android:layout_height="wrap_content">

    <TextView
        android:id="@+id/Content_txt"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="TextView"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <ImageButton
        android:id="@+id/imageButton"
        android:layout_width="48dp"
        android:layout_height="48dp"
        android:layout_marginStart="16dp"
        android:layout_marginTop="44dp"
        android:background="@android:color/transparent"
        android:scaleType="fitCenter"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:srcCompat="@drawable/ic_pencil" />  </androidx.constraintlayout.widget.ConstraintLayout>

I want to add 3 items of this layout to a list view. They are displayed fine but when I click on each item. The listener doesn't seem to be invoked.

Here's the implementation inside main activity and the class "item_adapter" which extends ArrayAdapter:

Main_activity:

package com.example.selectedlist;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.view.MotionEvent;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;

import java.util.ArrayList;

public class MainActivity extends AppCompatActivity
{
    ListView list;
    int selected;

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ArrayList<String> arr = new ArrayList<>();
        arr.add("ABC");
        arr.add("MGH");
        arr.add("EFG");

        selected = 0;
        list = findViewById(R.id.my_list);
        item_adapter adapter = new item_adapter(this, arr);

        list.setAdapter(adapter);
        list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
                TextView txt = (TextView)view.findViewById(R.id.Content_txt);
            txt.setText("dasd");
            }
        });
    }
}

item_adapter:

package com.example.selectedlist;

import android.animation.LayoutTransition; 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 androidx.annotation.NonNull; import androidx.annotation.Nullable;

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

public class item_adapter extends ArrayAdapter<String> {
    Context main_context;
    List<String> data;

    public item_adapter(@NonNull Context context, @NonNull List<String> objects)
    {
        super(context, R.layout.edit_layout, objects);
        main_context = context;
        data = objects;
    }


    @NonNull
    @Override
    public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent)
    {
        String str = getItem(position);

        View view = LayoutInflater.from(main_context).inflate(R.layout.edit_layout, parent, false);
        TextView txt = view.findViewById(R.id.Content_txt);
        txt.setText(str);

        return view;
    } }

Nothing happens when I click on each item. The TextView in the layout is supposed to be changed as shown in the code. Any ideas on this?

Answer 1

Please use below code

list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
                TextView txt = (TextView)view.findViewById(R.id.Content_txt);
                txt.setText("dasd");
            }
        });

Simply use the method setFocusable of the ImageButton for the listener to work.

ImageButton Edit_btn = view.findViewById(R.id.imageButton);
Edit_btn.setFocusable(false);
