How to get onItemclick from listview in a AlertDialog

I have an Activity with three Identical Buttons and three Identical TextViews. Each button onClick invokes a AlertDialog by following code:

    PickerDialog = new PickerDialogFragment();
    PickerDialog.show(getSupportFragmentManager(), "PickerDialog");

My AlertDialog has an EditText with addTextChangedListener

searchText.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {
        }
        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            adapter.getFilter().filter(s);
            adapter.notifyDataSetChanged();
        }
        @Override
        public void afterTextChanged(Editable s) {
        }
    });

and the listview adapter extends cursoradapter and implements filterable

listView.setTextFilterEnabled(true);
    adapter.setFilterQueryProvider(new FilterQueryProvider() {
        @Override
        public Cursor runQuery(CharSequence constraint) {
            return dbHelper.filterCodes(db, constraint); //returns a cursor
        }
    });

What I am trying to achieve is to directly change button text on user selected value from Listview inside AlertDialog.

Apart from this If possible I would like to set the value of edittext with user selected value from filtered list and then on clicking of positive button I would the values of each button

So my question is what goes inside listview.onItemClickListener and builder.setPositiveButton and builder.setNegativeButton

I am also not able to identify which button invoked the AlertDialog and making different alertdialog for each button will only increase lines of code

Add an 'int resid' parameter to the constructor of your class. Instantiate your dialog with 'new PickerDialogFragment(R.id.button1);'. Use resid in findViewById to get the button instance and set its text.
