i need way predict width of string if added inside element. the font size 16px. original idea 16px every character ended being wrong.. ideas? you can append string body so: function get_width_of_string() { var div = document.createelement('div'); div.style.position = "absolute"; div.style.marginleft = "-99999px"; div.style.display = "inline-block"; div.innerhtml = "this string"; document.body.appendchild(div); var width = div.offsetwidth; document.body.removechild(div); return width; } this should return width of string

i have been using using listview since long experienced of random behaviour. when call invalidateviews() on listviews, in cases re-inflates views each row , in cases doesn't. random. can tell me how works? ideally should refresh data inside views(rows) , not inflate them again. thanks calling invalidateviews() on listview should not re-inflates listview item views. way force listview re-inflates item views, meaning recycled views cleared, resetting listview adapter ( had dig in source code discover ). if take @ invalidateviews() method implementation (source code in abslistview.java), see (android api 16) : /** * causes views rebuilt , redrawn. */ public void invalidateviews() { mdatachanged = true; remembersyncstate(); requestlayout(); invalidate(); } the method remembersyncstate() implemented in adapterview.java stores listview's position of selected item (if any), can check out. the requestlayout() method takes care of measuring...

i have query interested in, full explanation though cannot find answers anywhere can explain me how jvm (java virtual machine) uses stacks , stack frames in order organise computations? the java bytecode so-called stack-oriented programming language . model used lot of virtual machines - in contrast architecture of physical machines. here example: public static int foobar(int value) { return value + 42; } the java bytecode of method looks follows: iload_0 bipush 42 iadd ireturn these instructions not use registers . instead use stack computation: push first argument onto stack. push constant 42 onto stack. pop 2 elements stack, add them , push result onto stack. pop top element stack , return it. it's same other java bytecode operations. there no registers can used. operations push and/or pop elements onto , stack.
