Question

I have a alertdialog that I know I will be using in multi classes thoughout my app and you can tell I would rather place it in its own class and call it when nessary. Its a simple text field and ok/cancel buttons. I always want to pass some text into it and after the user has clicked OK I want a variable to be updated with the updated text string

Whats the best way at converting this code so it can be used else where

LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
final View layout = inflater.inflate(R.layout.dialog_layout, null);

editTextfield = (EditText) layout.findViewById(R.id.comment_text);
editTextfield.setText(text);

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setView(layout);
builder.setTitle(R.string.title);

builder.setPositiveButton(android.R.string.ok, new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int id) {

        text = editTextfield.getText().toString();

            removeDialog(DIALOG);

});
builder.setNegativeButton(android.R.string.cancel, new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int id) {

           removeDialog(DIALOG);

    }
});

AlertDialog dialog = builder.create();
return dialog;

Thanks for you time
