Android Searchview gets refocused when returning from another fragment-CodePudding

Currently using jetpack navigation and want to use a single activity. However, the searchview keeps regaining focus whenever I return from the card details back to the search, even though I have removed focus after clicking search. See here.

What I'm currently doing to remove focus is I have a dummy view above my toolbar

    <com.google.android.material.appbar.MaterialToolbar
        android:id="@ id/database_toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_constraintTop_toTopOf="parent"
        style="@style/Widget.MaterialComponents.Toolbar.Primary" />

    <!-- Dummy view for receiving focus after SearchView clears focus -->
    <View
        android:id="@ id/focus_dummy_view"
        android:focusableInTouchMode="true"
        android:focusable="true"
        android:background="@android:color/transparent"
        android:layout_width="match_parent"
        android:layout_height="1dp"
        app:layout_constraintBottom_toTopOf="@id/database_toolbar" />

and after I perform a search, I do

    searchView.clearFocus()
    binding.focusDummyView.requestFocus()

My current workaround is to host the details in an activity, but I'd rather not. I have tried making a new project and the searchview seems to still get focus but the keyboard doesn't flicker?

Some additional context is that this only occured after updating to "androidx.fragment:fragment-ktx:1.4.0" from 1.2.5. I raised this issue in bugtracker but they have not responded to me yet. Wondering if anybody knows a fix?

Why don't you try

In Kotlin

     override fun onResume(){
        super.onResume()
        // Only runs if there is a view that is currently focused
        searchView.currentFocus?.let { view ->
        val imm = getSystemService(Context.INPUT_METHOD_SERVICE) as? InputMethodManager
        imm?.hideSoftInputFromWindow(view.windowToken, 0)
        searchView.clearFocus()

}
   
        }

You have to add this two lines of code in your root layout xml. To Clear focus from a View you can call getCurrentFocus().clearFocus() But remember that this will Simply move focus from current view to the first element in your view, not Completely removing focus from views; So if the first element in your layout is a EditText it's going to gain focus again.

A way to make sure your view doesn't get focus again is to add this attributes to your root view in your xml, enabling root view to capture focus.

android:focusableInTouchMode="true"
android:descendantFocusability="beforeDescendants"

After that you need to clear focus from onResume() I think it will help.
