问如何在android的alert builder中添加另一段代码？

    public void yourAlertDialog(int title, int message, int value, YourResultListener listener) {
                final View v;

                // inflate additional layout 
-->             v = LayoutInflater.from(this).inflate(R.layout.edit_text, null);

                // find desired views in the inflated layout:
-->             final EditText et = (EditText) v.findViewById(R.id.edit_text);
-->             et.setText("Your text - it may be passed as parameter");

                // generate AlertDialog and return result if OK is pressed
                new AlertDialog.Builder(this)//
                        .setTitle(title)//
                        .setMessage(message)//
                        .setPositiveButton(android.R.string.ok, new DialogInterface.OnClickListener(){
                            @Override

                                if (listener != null) {
                                    //DO WHAT YOU NEED

                        .setNegativeButton(android.R.string.cancel, null)//
-->                     .setView(v)// adding additional view
                        .show();
    }
