How to get text from searchview?

Question

How can I get the text from Searchview in this case this is Search method

public void search(String query){
    adapter = new CustomAdapter(getBaseContext(),contactOps.searchCursor(query));
    lv.setAdapter(adapter);
}

and this is Searchview Listener, when I put searchview.query().toString in search method the application cracked ,How can I solve this problem ?

searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String query) {
            return false;
        }

        @Override
        public boolean onQueryTextChange(String newText) {
            search(searchView.getQuery().toString());
            return false;
        }
    });

I deleted the code to define the search view take the xml and convert it to java code by mistake,because that the app stopped,I solved the problem thank to all of you — alaa, Jan 18 '18 at 05:44

Try this

searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
    @Override
    public boolean onQueryTextSubmit(String query) {
        return false;
    }

    @Override
    public boolean onQueryTextChange(String newText) {
        search(newText);
        return false;
    }
});

Instead

search(searchView.getQuery().toString());

If you want to take the text from the searchView it's basically the newText from the method onQueryTextChange.

 @Override
    public boolean onQueryTextChange(String newText) {
        //newText is the query you are searching 
        return false;
    }

use this way to get string from searchview:

searchview.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String query) {
            return false;
        }

        @Override
        public boolean onQueryTextChange(String newText) {
            if(newText.length() >= 1){
                search(newText);
            }
            return false;
        }
    });

Try this code:

searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
    @Override
    public boolean onQueryTextSubmit(String query) {
       //Here u can get the value "query" which is entered in the search box.
         return true;
        }

    @Override
    public boolean onQueryTextChange(String newText) {
        //This is your adapter that will be filtered
        return false;
    }
});
