I have a similar problem and would like to know if anyone could help me. I created the XML below and, as below, I placed within the Toolbar a SearchView. But I can not instantiate it in the Fragment code.
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin">
<SearchView
android:id="@+id/xProcurar"
android:background="@color/branco"
android:layout_width="match_parent"
android:layout_height="40dp"
android:elevation="5dp"
android:fitsSystemWindows="true"
android:layout_marginRight="10dp"
android:layout_marginLeft="10dp"
android:clickable="true"/>
</android.support.v7.widget.Toolbar>
When I try to instantiate this SearchView, as below, I take Null Point error as if the object did not exist in View (Fragment):
SearchView sv = (SearchView) view.findViewById(R.id.xProcurar);
Below is the entire Fragment XML
