Get the text in the search box of a action bar

It was a little difficult for me to get the text which is entered in the action bar to a string. Please check the below code .

public boolean onCreateOptionsMenu(Menu menu) {
    getSupportMenuInflater().inflate(R.menu.main, menu);

    SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    SearchView searchView = (SearchView) menu.findItem(R.id.menu_search)
            .getActionView();
    if (null != searchView) {
        searchView.setSearchableInfo(searchManager
                .getSearchableInfo(getComponentName()));
        searchView.setIconifiedByDefault(false);
    }

    SearchView.OnQueryTextListener queryTextListener = new SearchView.OnQueryTextListener() {
        public boolean onQueryTextChange(String newText) {
            // this is your adapter that will be filtered
            return true;
        }

        public boolean onQueryTextSubmit(String query) {
            //Here u can get the value "query" which is entered in the search box.

        }
    };
    searchView.setOnQueryTextListener(queryTextListener);

    return super.onCreateOptionsMenu(menu);
}

HTTP client to help test web services easily and efficiently

While i was dealing with Apps which is connect to serve the main issue i faced was checking the response. What i used at staring was debugging the app each time. In the case of json parsing I waste a lot of time only for checking the responses.
Then i got a solution Postman - REST Client.

It is very simple. You can POST or GET data to the server using postman.
