Set search widget back button functionality

Question

I have implemented the Android search widget in my navigation drawer based app. I have set it to open the keyboard and focus the editText when clicking on the search icon. I want to set the back button (up button) to hide the keyboard. I have searched the web for the R.id of the up button, and found this android.R.id.home. So I have set it to be:

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    ...
    case android.R.id.home:
        hideKeyboard();
        break;
    ...
}

I debugged the code and noticed that clicking on the navigation bar icon fires up the android.R.id.home, but hitting the up button of the search widget doesn't even enter the onOptionsItemSelected(MenuItem item) function. I have also tried this:

searchView.setOnFocusChangeListener(new OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        if (!hasFocus) {
            hideKeyboard();
        }
    }
});

But didn't work.

How can I hide the keyboard when pressing the back (up) button?

Setting the search view:

private void setSearchView(Menu menu) {
    // Get the SearchView and set the searchable configuration
    SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    searchView = (SearchView) menu.findItem(R.id.search).getActionView();
    // Assumes current activity is the searchable activity
    searchView.setSearchableInfo(searchManager
            .getSearchableInfo(getComponentName()));
    searchView.setIconifiedByDefault(false);

    SearchView.OnQueryTextListener queryTextListener = new SearchView.OnQueryTextListener() {
        public boolean onQueryTextChange(String newText) {
            Home.getFilter().filter(newText);
            return true;
        }

        public boolean onQueryTextSubmit(String query) {
            return true;
        }
    };
    searchView.setOnQueryTextListener(queryTextListener);
}

The following code should work:

searchView = (SearchView) menu.findItem(R.id.search).getActionView();

searchView.setOnCloseListener(new OnCloseListener() {
    @Override
    public bool OnClose() {
        searchView.clearFocus();
        return true;
});

However this didn't work for me for some reason. :-/

I found the workaround below here:

searchView = (SearchView) menu.findItem(R.id.search).getActionView();

searchView.addOnAttachStateChangeListener(new OnAttachStateChangeListener() {

    @Override
    public void onViewDetachedFromWindow(View v) {
        searchView.clearFocus();
    }

    @Override
    public void onViewAttachedToWindow(View v) {
        
    }
});

I don't think that using android.R.id.home will work since I think that onOptionsItemSelected(android.R.id.home) will only be called once the SearchView has been closed.

Have you check this thread? [SearchView's OnCloseListener doesn't work](http://stackoverflow.com/questions/9327826/searchviews-oncloselistener-doesnt-work/12975254#12975254) . Second part, that author shouldn't rely on `android.R.id.home` is fully corrent, though. — Konstantin Loginov, Jan 09 '16 at 17:12
