android - Orientation change: children of LinearLayout can't have @+id/something -


cross posting android google group

i ran issue earlier today: https://code.google.com/p/android/issues/detail?id=55106

the problem is:

  • linearlayout has children
  • every child inflated same xml layout file
  • a child has nested element id.
    • the id used call findviewbyid(id) set value
  • everything displayed on startup, after orientation change every child of linearlayout displays value of last data item
  • as id removed child xml layout file, starts working properly

the bug has sample project attached demonstrates problem.

just wanted ask if has experienced same issue , knows workaround?

thank in advance.

edit:

the situation linearlayout pretty flaky. made project work - see second attached project @ https://code.google.com/p/android/issues/detail?id=55106

if go item_main.xml , change android:textisselectable false true, bug shows up. keep android:textisselectable="true", remove android:id="@+id/text" - bug disappears again

the main reason experimenting linearlayout because wanted follow thy layout animation sample. http://developer.android.com/training/animation/layout.html

but seems situation unstable linearlayout , orientation change need go working listview+adapter approach , figure out how similar layout animations when adding items adapter , revalidating list.

another workaround removing views linearlayout in onsaveinstancestate method.

@override protected void onsaveinstancestate(bundle outstate) {     linearlayout linearlayout = (linearlayout) findviewbyid(r.id.yourlinearlayoutid);     linearlayout.removeallviews();     super.onsaveinstancestate(outstate); }

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
