How do I implement onClickListener on a custom adapter?

I am involved in building a simple time table management application. I have a list of courses. Each item in the list is a textview + delete button. The onClick listener on my list item is not working as expected. When I click the delete button, it works fine. However, I want to open some other actions when the user clicks on the text view of the list item.

code:

ShowAll.java (main activity where I show the list of classes)

package com.example.android.mytimetable;

import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;
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 ShowAll extends ActionBarActivity {
    private ArrayAdapter<String> adapter ;
    ArrayList <ClassDetail> classesDetail ;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_show_all);
        this.bindAdapter();

        ListView listView = (ListView) this.findViewById(R.id.class_list);
        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
                Log.v("Item", "clicked");
                Intent intent = new Intent(view.getContext(), ShowAllClicked.class);
                ClassDetail classDetail = classesDetail.get(i);
                Bundle bundle = new Bundle();
                bundle.putString("CLASS_NAME", classDetail.class_name);
                bundle.putString("BUILDING", classDetail.building);
                bundle.putString("MONDAY_START", classDetail.monday_start);
                bundle.putString("MONDAY_END", classDetail.monday_end);
                bundle.putString("TUESDAY_START", classDetail.tuesday_start);
                bundle.putString("TUESDAY_END", classDetail.tuesday_end);
                bundle.putString("WEDNESDAY_START", classDetail.wednesday_start);
                bundle.putString("WEDNESDAY_END", classDetail.wednesday_end);
                bundle.putString("THURSDAY_START", classDetail.thursday_start);
                bundle.putString("THURSDAY_END", classDetail.thursday_end);
                bundle.putString("FRIDAY_START", classDetail.friday_start);
                bundle.putString("FRIDAY_END", classDetail.friday_end);
                intent.putExtras(bundle);
                startActivity(intent);
            }
        });
    }

    void bindAdapter() {
        DBHelper db = new DBHelper(this);
        classesDetail = db.getClassesDetail();
        ArrayList <String> classes = new ArrayList<>();
        for(int i = 0 ; i < classesDetail.size() ; i++) {
            Log.v("Adding ", classesDetail.get(i).class_name);
            classes.add(classesDetail.get(i).class_name);
        }
        if(classes.size() == 0)
            ((TextView) this.findViewById(R.id.holiday)).setText(getString(R.string.noClass));
        CustomArrayAdapter customArrayAdapter = new CustomArrayAdapter(classes, this);
        ((ListView) this.findViewById(R.id.class_list)).setAdapter(customArrayAdapter);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_show_all, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.

        return super.onOptionsItemSelected(item);
    }
}

      

        
        
        
      

    

activity_show_all.xml (ShowAll.java xml layout)

I tried to help here: Set onClickListener on Custom Adapter and here: Where should I put onClickListener on Custom ListView?

However, I still cannot get the adapter to work. Any help would be appreciated
