public class webpage extends fragment { public static final string arg_section_number = "section_number"; private webview webview; public webpage() { } @override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) { view rootview = inflater.inflate(r.layout.webpage, container, false); textview pagenumber = (textview) rootview.findviewbyid(r.id.pagenumber); pagenumber.settext(integer.tostring(getarguments().getint(arg_section_number))); webview = (webview) rootview.findviewbyid(r.id.webview); int number = getarguments().getint(arg_section_number); string file = null; switch (number){ case 0: file = "morning.html"; break; case 1: file = "evning.html"; break; case 2: file = "prayer.html"; break; default: break; } webview.loadurl("file:///android_asset/"+file); return rootview; } @override public void onlowmemory() { super.onlowmemory(); } } hope figure out fix this. in advance
