OnItemLongClickListener does not work

[lisoslaw]

I encountered problem that I don't understand. I don't receive any errors in eclipse but the function of OnItemLongClick Listener does not kickstart my dialog file which should enable edition of row in the list.
Here are my codes:

[HIGH]
package com.example.classorganizer;


import java.util.ArrayList;

import android.app.ListActivity;
import android.content.Context;
import android.content.Intent;
import android.database.Cursor;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.BaseAdapter;
import android.widget.ListView;
import android.widget.TextView;

import com.cookbook.data.Constants;
import com.cookbook.data.MyDB;




public class Monday extends ListActivity {



private static final int MyMenu = 0;
MyDB dba;
DiaryAdapter myAdapter;

private class MyDiary{
public MyDiary(String t, String c){
title=t;
content=c;

ListView listView = new ListView(Monday.this);
listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
@Override
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
new EditListItemDialog(view.getContext()).show();
return true;

}
});


}

public String title;
public String content;

}
@Override
protected void onCreate(Bundle savedInstanceState) {
dba = new MyDB(this);
dba.open();
setContentView(R.layout.fragment_monday);



super.onCreate(savedInstanceState);
myAdapter = new DiaryAdapter(this);
this.setListAdapter(myAdapter);
}



private class DiaryAdapter extends BaseAdapter {
private LayoutInflater mInflater;
private ArrayList<MyDiary> fragment_monday;
public DiaryAdapter(Context context) {
mInflater = LayoutInflater.from(context);
fragment_monday = new ArrayList<MyDiary>();
getdata();


}

public void getdata(){
Cursor c = dba.getdiaries();
startManagingCursor(c);
if(c.moveToFirst()){
do{
String title =
c.getString(c.getColumnIndex(Constants.TITLE_NAME));
String content =
c.getString(c.getColumnIndex(Constants.CONTENT_NAME));

MyDiary temp = new MyDiary(title,content);
fragment_monday.add(temp);
} while(c.moveToNext());
}

}



@Override
public int getCount() {return fragment_monday.size();}
public MyDiary getItem(int i) {return fragment_monday.get(i);}
public long getItemId(int i) {return i;}
public View getView(int arg0, View arg1, ViewGroup arg2) {
final ViewHolder holder;

View v = arg1;
if ((v == null) || (v.getTag() == null)) {
v = mInflater.inflate(R.layout.diaryrow, null);
holder = new ViewHolder();
holder.mTitle = (TextView)v.findViewById(R.id.name);

v.setTag(holder);
} else {
holder = (ViewHolder) v.getTag();
}

holder.mdiary = getItem(arg0);
holder.mTitle.setText(holder.mdiary.title);


v.setTag(holder);

return v;


}

public class ViewHolder {
MyDiary mdiary;
TextView mTitle;


}

}




/** Called when the user clicks the Edit button */
public void visitDiary(View view) {
Intent intent = new Intent(this, Diary.class);
startActivity(intent);
}
/** Called when the user clicks the back button */
public void visitSchedule(View view) {
Intent intent = new Intent(this, DisplayScheduleScreen.class);
startActivity(intent);
}


}

and my Dialog file:

[HIGH]
package com.example.classorganizer;

import android.app.Dialog;
import android.content.Context;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;

class EditListItemDialog extends Dialog implements View.OnClickListener {

private View editText;

public EditListItemDialog(Context context) {
super(context);
}

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.edit_text_dialog);//here is your xml with EditText and 'Ok' and 'Cancel' buttons
View btnOk = findViewById(R.id.button_ok);
editText = findViewById(R.id.edit_text);
btnOk.setOnClickListener(this);
}

@Override
public void onClick(View v) {
((TextView) editText).getText().toString();//here is your updated(or not updated) text
dismiss();
}
}

[/HIGH]

As I said before, the code does not complain but on long click Dialog is not executed and row cannot be edited. Can anyone help me with sorting this out please?
