Fragment के साथ टूलबार में SearchView

        android:title="Search"

खोज के लिए थीम सेट करना

मूल रूप से app:actionViewClass रूप में निकाले गए SearchView के लिए एक थीम लागू करने के लिए app:actionViewClass से menu.xml , हमें यह समझने की आवश्यकता है कि यह अंतर्निहित टूलबार पर लागू शैली पर पूरी तरह से निर्भर करता है। टूलबार को थीम प्राप्त करने के लिए निम्नलिखित चरणों को लागू करें।

styles.xml में एक शैली बनाएँ

<style name="ActionBarThemeOverlay">
     <item name="android:textColorPrimary">@color/prim_color</item>
     <item name="colorControlNormal">@color/normal_color</item>
     <item name="colorControlHighlight">@color/high_color</item>
     <item name="android:textColorHint">@color/hint_color</item>
</style>

टूलबार पर शैली लागू करें।

<android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        app:theme="@style/ActionBarThemeOverlay"
        app:popupTheme="@style/ActionBarThemeOverlay"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="@color/colorPrimary"
        android:title="@string/title"
        tools:targetApi="m" />

यह टूलबार (बैक बटन, मेनू आइकन और खोज दृश्य) के अनुरूप सभी दृश्यों को वांछित रंग देता है।
