Answer 1

It also can be done with RXAndroid and RxBinding by Jake Wharton like this:

RxSearchView.queryTextChanges(searchView)
            .debounce(500, TimeUnit.MILLISECONDS)
            .observeOn(AndroidSchedulers.mainThread())
            .subscribe(new Action1<CharSequence>() {
                @Override
                public void call(CharSequence charSequence) {
                    if(charSequence!=null){
                        // Here you can get the text
                        System.out.println("SEARCH===" + charSequence.toString());
                    }
                }
            });

Code is subscribing to observe text change with some delay of 500 milliseconds.

In Kotlin, you can do :

searchView.setOnQueryTextListener(object : OnQueryTextListener {

    override fun onQueryTextChange(newText: String): Boolean {
        return false
    }

    override fun onQueryTextSubmit(query: String): Boolean {
        // task HERE
        return false
    }

})

This is what I have inside the onCreateOptionsMenu(Menu menu) function on my main activity:

MenuItem searchItem = menu.findItem(R.id.search);
SearchView searchView = (SearchView) searchItem.getActionView();
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
    @Override
    public boolean onQueryTextSubmit(String query) {
        // Do whatever you need. This will be fired only when submitting.
        return false;
    }

    @Override
    public boolean onQueryTextChange(String newText) {
        // Do whatever you need when text changes. 
        // This will be fired every time you input any character.
        return false;
    }
});

Answer 4

Try to use setOnQueryTextListener of SearchView

new SearchView.OnQueryTextListener() {
    @Override
    public boolean onQueryTextChange(String newText) {
        // your text view here
        textView.setText(newText);
        return true;
    }

    @Override
    public boolean onQueryTextSubmit(String query) {
        textView.setText(query);
        return true;
    }
}

Answer 5

The right way to solve this is to use setOnQueryTextListener

This is a small exmple using Kotlin:

txtSearch = rootView.searchView 
txtSearch.setOnQueryTextListener(object : SearchView.OnQueryTextListener {

        override fun onQueryTextChange(newText: String): Boolean {
            return false
        }

        override fun onQueryTextSubmit(query: String): Boolean {
            return false
        }
 })

Answer 6

The above answer is good but not complete actually you need to set an action listener for your Search view . you can do this in two ways create a class that implements the necessary classes to be an OnQueryTextListener and make a new object of that and use it as your search view query text listener or use the following compact form:

        SearchView searchView = (SearchView) menu.findItem(R.id.action_search).getActionView();
        searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
            @Override
            public boolean onQueryTextSubmit(String query) {
                callSearch(query);
                return true;
            }

            @Override
            public boolean onQueryTextChange(String newText) {
//              if (searchView.isExpanded() && TextUtils.isEmpty(newText)) {
                    callSearch(newText);
//              }
                return true;
            }

            public void callSearch(String query) {
                //Do searching
            }

        });
