Remove SearchView search voice button line

Question

Thanks to other SO related posts regarding SearchView customisation I was able to customise my SearchView to this point:

Now I'm trying to add voice search and I was able to change the voice button background resource:

int searchVoiceIconId = searchPlate.getContext().getResources().getIdentifier("android:id/search_voice_btn", null, null);
ImageView searchVoiceIcon = (ImageView) searchView.findViewById(searchVoiceIconId);
searchVoiceIcon.setImageResource(R.drawable.ic_action_mic);
searchVoiceIcon.setBackgroundColor(Color.TRANSPARENT);

However, I can't seem to get rid of the line under the voice search button.

any suggestions????

Thanks

This is a late reply but it might be helpful for future.

Add the following line:

<style name="AppTheme.SearchView" parent="Widget.AppCompat.SearchView">
    <!-- Gets rid of the "underline" in the mic button-->
    <item name="submitBackground">@null</item>

To your values/styles.xml file and it will remove the line.
