How to cancel preference dialog closing after positive button click?

Question

How I can cancel preference dialog closing aftet any button clicked?

I solved to make that my dialog class implemented OnClickListener.

public class PassChangeDiglog extends DialogPreference implements
        OnClickListener {
    EditText oldpass, new_pass1, new_pass2;

    public PassChangeDiglog(Context context, AttributeSet attrs) {
        super(context, attrs);
        setDialogLayoutResource(R.layout.pass_change_diglog);
        setPositiveButtonText("OK");
        setNegativeButtonText(R.string.Cancel);

    }


@Override
protected void onBindDialogView(View view) {
    setTitle(R.string.PassChanging);
    oldpass = (EditText) view.findViewById(R.id.Dlg_old_pass);
    new_pass1 = (EditText) view.findViewById(R.id.Dlg_NewPass1);
    new_pass2 = (EditText) view.findViewById(R.id.Dlg_NewPass2);

    super.onBindDialogView(view);
}


    @Override
    public void onClick(DialogInterface arg0, int arg1) {
        switch (arg1) {
        case DialogInterface.BUTTON_POSITIVE:
           boolean needclose;
           ...
           if (needclose)
               arg0.dismiss();
           else{
               //do not close
           }
        }

    };
}

I tried to override onDismiss method, but dialog whatever closing.

@Override
public void onDismiss(DialogInterface dialog) {
    // TODO Auto-generated method stub
    Log.d("MY","onDismiss");
    //super.onDismiss(dialog);
}

The solution of my question is overriding of showDialog-method.

@Override
protected void showDialog(Bundle state) {
    // TODO Auto-generated method stub
    super.showDialog(state);
    ((AlertDialog) getDialog()).getButton(AlertDialog.BUTTON_POSITIVE)
            .setOnClickListener(this);
}
