How to clear text from search menu android

I've created a search in my application. Also database and contant provider. When I click on the term in the search, then starts an activity that leads to explanation of this term. When I go back to the previous activity, the text is still visible in the search box. I'd like to be automatically cleared.

I was looking for solution to the problem, but I have not found it. Please help!

SearchableDictionary.java

 @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.searchable_dictionary, menu);

        MenuItem item = menu.findItem(R.id.search);

        SearchView searchView = SearchView)MenuItemCompat.getActionView(item);

        SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
        SearchableInfo info = searchManager.getSearchableInfo(getComponentName());
        searchView.setSearchableInfo(info); 
        searchView.setIconified(true);

I tried with: searchView.clearFocus(); searchView.setQuery("", false); but it did not work for me.

Solution

onCreateOptionsMenu will most likely not be called when you go back to the previous activity as unless there are memory constraints the activity will not be killed and restarted.

I would recommend calling searchView.setQuery("", false) in the callback when the user clicks on a result. Then start the new Activity and when the user returns the search field will already have been cleared.
