You have two instances of `searchView=(SearchView)...` figure out which is correct — OneCricketeer, Apr 16 '17 at 21:36

If you want it in the actionbar, then remove it from the Activity. Add it in searchmenu.xml.

Your error is related to these lines here, so fix that xml file you're inflating

getMenuInflater().inflate(R.menu.searchmenu,menu);
searchView=(SearchView)menu.findItem(R.id.search).getActionView();
searchView.setIconifiedByDefault(true);

And you can effectively remove this searchview

void views(){
    l=(ListView)findViewById(R.id.list);
    // searchView=(SearchView)findViewById(R.id.serch);

}

so i have to put my search view in items,as in the search xml file where i created menu and add a item — Parteekj, Apr 17 '17 at 13:33
