When I click SearchView, click event doesn't fire (Xamarin.Android)

Question

I have the following SearchView

<SearchView
    android:minWidth="25px"
    android:minHeight="25px"
    android:background="@drawable/rounded_border"
    android:clickable="true"
    android:iconifiedByDefault="false"
    android:focusable="false"
    android:layout_weight="1"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:id="@+id/searchViewCustomers" />

When I click on it I want one of the widgets of the activity to become visible and the other one to become gone like that:

searchView.Click += delegate
{
    customersRecyclerView.Visibility = ViewStates.Visible;
    customerDataContainer.Visibility = ViewStates.Gone;
};

But when I run the application and tap on the searchView the widgets doesn't become visible/gone and when I put break point on serachView.Click, program execution never stops there. How to make the widgets visible/gone when I tap on the searchView widget?

Answer 1

The way I would do it is, add a focus change event to the searchview :

 searchView.FocusChange += SearchView_FocusChange;
 private void SearchView_FocusChange(object sender, View.FocusChangeEventArgs e)
    {
              if(searchView.HasFocus)
              {
               //Visibility code
              }
    }

UPDATE : First and foremost I would use the Appcompat Searchview for compatibility purpose, Something like this:

<android.support.v7.widget.SearchView
android:minWidth="25px"
android:minHeight="25px"
android:background="@drawable/rounded_border"
android:clickable="true"
android:iconifiedByDefault="false"
android:focusable="false"
android:layout_weight="1"
android:layout_width="match_parent"
android:layout_height="0dp"
android:id="@+id/searchViewCustomers" />

Then I would try using the focus change listener(Same as Above).

If that does not work I would use on query focus change listener something like this:

searchView.SetOnQueryTextFocusChangeListener(new FocusChangeListenerClass());

And add the listener class something like this :

public class FocusChangeListenerClass : Java.Lang.Object, IOnFocusChangeListener
{
    public void OnFocusChange(Android.Views.View v, bool hasFocus)
    {

    }
}

Update:

Activity:

public class ClientsActivity : Activity
{
    .......
    .......
    Android.Widget.SearchView searchView;
    RecyclerView customersRecyclerView;
    ScrollView customerDataContainer;
    .......
    protected override void OnCreate(Bundle savedInstanceState)
    {
         ........
         ........
         searchView.SetOnQueryTextFocusChangeListener(new FocusChangeListenerClass(ref customersRecyclerView, ref customerDataContainer));
    }
}

FocusChangeListenerClass.cs:

public class FocusChangeListenerClass : Java.Lang.Object, IOnFocusChangeListener
{
    RecyclerView customersRecyclerView;
    ScrollView customerDataContainer;
    public FocusChangeListenerClass(ref RecyclerView recyclerView, ref ScrollView dataContainer)
    {
        customersRecyclerView = recyclerView;
        customerDataContainer = dataContainer;
    }

    public void OnFocusChange(Android.Views.View v, bool hasFocus)
    {
        if(hasFocus == true)
        {
            customersRecyclerView.Visibility = ViewStates.Visible;
            customerDataContainer.Visibility = ViewStates.Gone;
        }
        else
        {
            customersRecyclerView.Visibility = ViewStates.Gone;
            customerDataContainer.Visibility = ViewStates.Visible;
        }
    }

}

There is no need to change <SearchView> to <android.support.v7.widget.SearchView> in the .axml file.
