Android เกี่ยวกับ onActivityResult ที่ใช้ google voice ครับ

if (requestCode == RESULT_SPEECH
                && resultCode == RESULT_OK && data != null) {
            ArrayList<String> arr_data =
                    data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);

            final String[] arr_str = new String[arr_data.size()];
            for (int i = 0; i < arr_str.length; i++)
                arr_str[i] = arr_data.get(i);

            AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
            builder.setTitle("Recognize result");
            builder.setItems(arr_str, new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {
                    I1.setText(arr_str[which]);
                }
            });
            builder.show();
        }
