android - Open context menu by clicking on menu options item -

-

i use android make application. have activity create option menu below

    @override public boolean oncreateoptionsmenu(menu menu) {     menuinflater inflater = getmenuinflater();     inflater.inflate(r.menu.mymenu, menu);     return true; }

the menu loaded xml file :

<?xml version="1.0" encoding="utf-8"?><menu xmlns:android="http://schemas.android.com/apk/res/android"> <item android:title="item1" android:id="@+id/item1" /></menu>

when click on item 1, use onoptionsitemselected on activity work after click :

    @override public boolean onoptionsitemselected(menuitem item) {     switch(item.getitemid()) {     case r.id.item1 :         // here, open contextual menu         return true;     default :         return super.onoptionsitemselected(item);     } }

so, when user click on item 1 open contextual menu. first, don't know if it's possible open contextual menu directly without using hold position on screen several tutorials on internet show it.

if it's possible how can open contextual menu in way ?

i thought use registerforcontextmenu() , opencontextmenu() in case of item 1 view should put in parameter ?

if has idea way make that, know how must that.

if want have contextual menu, i'd use contextual menu designed in android doing long-press on given item. people accustomed , apps shouldn't differ in that.

the alternativ bit more complex. have menu loaded in separate activity style dialog window (you know faded half-transparent background). can done applying theme.dialog style activity in manifest.xml file:

<activity android:name=".activities.tagpopupactivity"             android:label="tagging" android:theme="@android:style/theme.dialog">                 ... </activity>

alternatively can directly create dialog window described here. context (i.e. list click) implementing appropriate click listener in main list activity , when user clicks on item, retrieve id , package bundle forward "menu"-activity styled popup dialog.

javascript - Enclosure Memory Copies -

-
function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
