How to handle back button of Search View in android

Question

I have Develop an application that have search view in action bar and i got issue when i am do search its filter perfectly but when i am press back button its still showing filter data so my question is what is event of back button of Action Bar Search view.?

My Code of Search View is

SearchView searchView = (SearchView) MenuItemCompat.getActionView(menu.findItem(Menus.SEARCH));
    searchView.setQueryHint(this.getString(R.string.search));
    editSearch = (EditText) searchView.findViewById(android.support.v7.appcompat.R.id.search_src_text);
    editSearch.setHintTextColor(getResources().getColor(R.color.white));
    searchView.setOnQueryTextListener(OnQuerySearchView);


 private OnQueryTextListener OnQuerySearchView = new OnQueryTextListener() {

    @Override
    public boolean onQueryTextSubmit(String newText) {
        if (TextUtils.isEmpty(newText)) {
            listAllContact.clearTextFilter();
        } else {
            listAllContact.setFilterText(newText.toString());
        }
        return true;
    }

    @Override
    public boolean onQueryTextChange(String newText) {
        String text = editSearch.getText().toString()
                .toLowerCase(Locale.getDefault());
        adapter.filter(text);
        return true;
    }

};

Filter Method in Adapter

public void filter(String charText) {
    charText = charText.toLowerCase(Locale.getDefault());
    propertyList.clear();

    if (charText.length() == 0) {
       propertyList.addAll(arrayList);
    notifyDataSetChanged();

    } else {
        for (ContactProperty p : arrayList) {
            if (p.getFriendName().toLowerCase(Locale.getDefault())
                    .contains(charText)) {
                propertyList.add(p);
            }
        }
        notifyDataSetChanged();

    }

Answer 1

You will don't get the direct event of that searchView navigation click, there is an interface of MenuItam, the name is "MenuItem.OnActionExpandListener()". By using this interface you can get expand and collapsed callback.

Use this below snippets code,

MenuItem searchMenuItem = menu.findItem(R.id.action_search);
searchMenuItem.setOnActionExpandListener(new MenuItem.OnActionExpandListener() {
            @Override
            public boolean onMenuItemActionExpand(MenuItem item) {
                return true;
            }

            @Override
            public boolean onMenuItemActionCollapse(MenuItem item) {
                return true;
            }
        });

This will collapse the search action item when its focus is lost:

@Override
public boolean onCreateOptionsMenu(Menu menu)
{
    getMenuInflater().inflate(R.menu.main_menu, menu);
    searchItem = menu.findItem(R.id.action_search);
    searchView = (SearchView) MenuItemCompat.getActionView(searchItem);

    // be sure to use 'setOnQueryTextFocusChangeListener()'
    searchView.setOnQueryTextFocusChangeListener(new View.OnFocusChangeListener()
    {
        @Override
        public void onFocusChange(View v, boolean newViewFocus)
        {
            if (!newViewFocus)
            {
                //Collapse the action item.
                searchItem.collapseActionView();
                //Clear the filter/search query.
                myFilterFunction("");
            }
        }
    });

    return super.onCreateOptionsMenu(menu);
}

This is the only way I've found to successfully collapse the search item action view when hitting the back button.
