Rendering Problems Couldn't resolve resource @id/search_edit_frame

This is the rendering error I'm getting in my xml file. I think it has something to do with my support.v7.SearchView below is my xml:

 <RelativeLayout
    android:id="@+id/layout_ricerca"
    android:layout_width="match_parent"
    android:layout_height="50dp"
    android:background="@drawable/search_border_backgroud"
    android:layout_marginStart="10dp"
    android:layout_marginEnd="10dp"
    android:layout_marginTop="20dp">

    <android.support.v7.widget.SearchView
        android:id="@+id/testo_ricerca"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:queryHint="@string/search_hint"
        android:textSize="25sp"
        android:layout_marginStart="5dp"
        android:iconifiedByDefault="false"/>

    <ImageButton
        android:id="@+id/tasto_ricerca"
        android:background="@color/trans"
        android:layout_marginTop="2dp"
        android:layout_width="45dp"
        android:layout_height="match_parent"
        android:layout_marginEnd="3dp"
        android:scaleType="centerInside"
        android:layout_alignParentEnd="true"
        android:src="@drawable/tasto_ricerca"/>
</RelativeLayout>

When I change the <android.support.v7.widget.SearchView to <SearchView the error disappears, but that's not a good solution for me because I would have to change all my java code to work with the SearchView instead of the android.support.v7.widget.SearchView.

Does anyone know how to fix this problem ? why does it happen? I don't think there is anything wrong with my xml.

Edit:

Added screenshot of the error

When you have lot of cache memory data are store in Android Studio that time this type of error is coming..

There are many way to solve it.

1. Quickest way to do that is File → Invalidate caches / Restart... → Just Restart.

2. Right click on project and Synchronize ...Project

3. click on Build menu --> select Clean Project and then Rebuild it.
