What is the method to ensure that the bottom navigation bar stays hidden when the SearchView or Dialog is selected or focused in Android Studio with Java?

There are several ways to achieve this, but one simple method is to use the setOnFocusChangeListener method with the getWindow() method to get the window of the current activity and then set the visibility of the bottom navigation bar as needed.

Here's an example implementation:

searchView.setOnQueryTextFocusChangeListener((view, hasFocus) -> {
    if (hasFocus) {
        getWindow().getDecorView().findViewById(R.id.bottom_navigation).setVisibility(View.GONE);
    } else {
        getWindow().getDecorView().findViewById(R.id.bottom_navigation).setVisibility(View.VISIBLE);
    }
});

In this example, we set a OnFocusChangeListener for the searchView and check if it has focus. If it does, we use the getWindow() method to get the current activity window and then retrieve the bottom_navigation view by calling findViewById. We then set its visibility to GONE (i.e., hide it). When the searchView loses focus, we set the visibility of the bottom_navigation view to VISIBLE again.

You can use a similar approach for handling the dialog focus as well. Simply set a focus change listener for the dialog's searchView or any other view that you want to hide the bottom navigation for.
