just change layout id in oncreateview() simple_list_item_2 simple_list_item_1

public view oncreateview(layoutinflater inflater,viewgroup container,                          bundle savedinstancestate) {     // inflate layout fragment     view view = inflater.inflate(r.layout.activity_call, container, false);     calllistview = (listview)view.findviewbyid(r.id.listview1);     arrayadapter = new arrayadapter<string>(getactivity().getapplicationcontext(), android.r.layout.simple_list_item_1,calllist1);     calllistview.setadapter(arrayadapter);     getcalldetails();     return view; } 

explanation :

why not android.r.layout.simple_list_item_2?

creating new arrayadapter need textview layout parameter, android.r.layout.simple_list_item_2 twolinelistitem layout containing 2 textviews inside it. you can check typing android.r.layout.simple_list_item_2 string in java file put cursor on , press ctrl key. can see layout.

why android.r.layout.simple_list_item_1?

android.r.layout.simple_list_item_1 textview. fulfills requirement of arrayadapter layout being textview. reason have suggested use layout.
