Android list with multiple list item layouts - based on few tutorials, tried simple android app shows list strings. problem when tried introduce new layout list items. so have: listitem1 -> layout1 listitem2 -> layout2 listitem3 -> layout1 etc when tried adding new layout, items became "scrambled" when scrolling. example, display item1, item2, item3, item4... , , when scrolling downwards , coming back, list be: item40, item3, item20, item1 etc here's code have: (the activity_main.xml file has linearlayout > listview) protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_main); items = new arraylist<string>(); (int = 0; < 50; i++){ items.add(i%2==0 ? "true" : "false"); } listview listview = (listview) findviewbyid(r.id.listviewid); listview.setadapter(new listitemadapter(this, android.r.layout.simple_li...

VHDL bit rotation function syntax error? - i doing school work i'm making own rolling/shifting function. below code wrote, when seek compile syntax error on rownum<=rol(rowcount,1); library ieee; utilize ieee.std_logic_1164.all; utilize ieee.numeric_std.all; architecture main of proj function "rol" (a: std_logic_vector; n : natural) homecoming std_logic_vector begin homecoming std_logic_vector(unsigned(a) rol n); end function; signal rownum : std_logic_vector(2 downto 0); signal rowcount : std_logic_vector(2 downto 0); begin process begin wait until rising_edge(i_clock); **rownum<=rol(rowcount,1);** end process; end architecture main; there couple of things need addressed here. firstly, need entity statement: entity proj port( i_clock : in std_logic ); end proj; this declares signals inputs , outputs entity. in case, it's clock. can add together rownum , rowcount inputs , outputs needed. your f...

performance - A better performing way retrieving select attributes Collections of Large Objects in Java - is there method can iterate collection , only retrieve subset of attributes without loading/unloading each of total object cache? 'cos seems waste load/unload whole (possibly big) object when need attribute(s), if objects big. might cause unnecessary cache conflicts when loading such unnecessary data, right? when meant 'load cache' mean 'process' object via processor. there objects of ex: 10 attributes. in iterating loop utilize 1 of those. in such scenario, think waste load other 9 attributes processor memory. isn't there solution extract attributes without loading total object? also, google's guava solve problem internally? thank you! it's not first place look, it's not impossible you're running cache sharing problems. if you're convinced (from realistic profiling or analysis of hardware counters) bottleneck worth ...
