Question: I'm using a search view in my application. Now i just want to get the text typed in the SearchView text box and display it on another textview. If i typed the text and click a button i can do the same. But i don't want to use any extra buttons. I just want to display the result when i am pressing enter key.

Answer: 
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. 

This is a link to git repo to get RXAndroid:

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;
    }
});

```
