How to remove white underline in a SearchView widget in Toolbar Android
If you are using SearchView then use for API below 21
android:queryBackground="@android:color/transparent"you can use below code if you are using API 21 or more
app:queryBackground="@android:color/transparent"
Once try as follows
View v = searchView.findViewById(android.support.v7.appcompat.R.id.search_plate);v.setBackgroundColor(Color.parseColor("here give actionbar color code"));Hope this will helps you.
Just add this line if you are using a v7 or androidx widget
app:queryBackground="@android:color/transparent"
