As I do to change the background color and letters of a painting, I wanted to implement SearchView in the ActionBar, for that I went through menu_search
?xml version="1.0" encoding="utf-8"?>
menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
and for searchable
?xml version="1.0" encoding="utf-8"?>
searchable xmlns:android="http://schemas.android.com/apk/res/android"
android:hint="@string/search_string"
android:label="@string/app_name"
android:searchSuggestAuthority="ohmiosmega.p_v0.CitySuggestionProvider"
android:searchSuggestIntentAction="android.intent.action.VIEW"
android:searchSuggestIntentData="content://ohmiosmega.p_v0.citysuggestion.city"/>
