android - text selection with no titlebar will cause crush -

i hide titlebar below , works.

public class mainactivity extends actionbaractivity { @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); requestwindowfeature(window.feature_no_title); setcontentview(r.layout.activity_main); } }

however when long click , start word selection in webview or edittext, application crush.

i think because word selection utilize space of titlebar.

how can solve it?

is activity extends actionbaractivity. if "yes " need write custom theme.

android android-titlebar
