SearchView + Filterable RecyclerView make SearchView losing focus

Question

I have both searchView and recyclerView in same layout. recyclerView is using filter and it's working properly.

The problem occurred when i entered query on searchView. Instead of let me finish typing, searchView will lose focus after i entered first character of my query. Let's say i want show all items which contain "1234" in its name, searchView will lose focus after i entered "1" then display all items which contain "1". I have to click that searchView again if i want to continue.

Here is my layout (in fragment):

<LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <android.support.v7.widget.SearchView
            android:id="@+id/sv_test"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="@android:color/transparent"
            android:inputType="number"
            app:iconifiedByDefault="false"
            app:queryBackground="@android:color/transparent"
            app:queryHint="Hint"
            app:theme="@style/AppSearchView">

        </android.support.v7.widget.SearchView>

        <View
            android:id="@+id/divider50"
            android:layout_width="match_parent"
            android:layout_height="1dp"
            android:background="@color/light_grey"
            android:visibility="visible" />

        <android.support.v7.widget.RecyclerView
            android:id="@+id/rv_test"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />

    </LinearLayout>

Here is my filter command:

private void setSearchview() {
        searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
            @Override
            public boolean onQueryTextSubmit(String query) {
                adapter.getFilter().filter(query);

                return false;
            }

            @Override
            public boolean onQueryTextChange(String query) {
                adapter.getFilter().filter(query);

                return false;
            }
        });
    }

I have similar layout in custom alert dialog and it's working fine without any issues. Weird right?

If you have a focusable item (like an EditText) inside your RecyclerView, it might be stealing the focus on the first update. To disable the RecyclerView gaining any focus, you can add the descendantFocusability parameter to the XML like this:

    <android.support.v7.widget.RecyclerView
        android:id="@+id/rv_test"
        android:layout_width="match_parent"
        android:descendantFocusability="blocksDescendants"
        android:layout_height="wrap_content" />

If you need to focus inside the RecyclerView, you might work out a solution which sets this parameter dynamically (so it turns focus off before the update, and back on after it).
