Answer 1

If anyone experiences this same issue, the onQueryTextChange callback will be fired when replacing the Fragment when using the following action in your menu XML file when your SearchView is currently expanded:

android:showAsAction="always|collapseActionView"

When you attempt to use isVisible() (Java) or isVisible (Kotlin) in the onQueryTextChange callback as a way to determine if the Fragment is actually visible or not, the value returned will always return true.

The reason for this is that the onQueryTextChange callback will be fired when you're SearchView is currently expanded when you attempt to change Fragment's.

The default action of collapseActionView at this stage is to collapse the SearchView when changing Fragment's.

Solution:

Simply call your SearchView !isIconified (Kotlin) method in your onQueryTextChange callback and only set your logic if it returns false, i.e. the SearchView is currently expanded. Full example described below:

yourSearchView.setOnQueryTextListener(object: SearchView.OnQueryTextListener {
    override fun onQueryTextSubmit(query: String?): Boolean {
        // Do search query here if you use a submit action
        return true
    }

    override fun onQueryTextChange(newText: String?): Boolean {
        if (!yourSearchView.isIconified) {
            // Don't execute your search query here when SearchView is 
            // currently open
            return true
        }
        // Do search query here
        return true
    }
})
