Quiero algo como esto ---> Requerido
Entonces, lo que quiero exactamente es que cuando el usuario escriba un nombre de tema en particular (si está presente en la aplicación) en la vista de búsqueda, debería poder dar sugerencias y, si lo encuentra, debería abrir esa actividad de tema ( como Facebook, Instagram, ... etc. búsquedas ) ... y esos títulos provienen de API (que he mostrado con éxito en otras actividades) ... como este -> [ ingrese la descripción de la imagen aquí ... ¿ cuál será la lógica para ello? necesito ayuda ... gracias
así que acabo de incluir searchview en XML como este ->
<SearchView
android:id="@+id/searchView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:queryHint="Search Here"
android:iconifiedByDefault="false"
android:layout_alignParentTop="true"
android:background="@drawable/search_bar"
android:layout_marginLeft="15dp"
android:layout_marginRight="15dp"
android:layout_marginTop="20dp"
android:pointerIcon="crosshair"
android:theme="@style/Widget.AppCompat.SearchView"
android:focusedByDefault="true"
/>
Necesita ayuda ... gracias de antemano ...
