java - Android custom view layout issues -

-

short , sweet summary:

when changing class view-derived viewgroup-derived, height and/or width params passed onsizechanged not consistent class when used inside of linearlayout. there additional information need supply when using viewgroup super class achieve consistent results?

long version:

i have created custom view-derived visual control i'm using custom button. derive view , add layouts this:

class declaration:

public class gamebutton extends view {

xml:

    <linearlayout         android:layout_width="fill_parent"         android:layout_height="0dip"         android:orientation="horizontal"         android:layout_weight="1">         <com.myname.myapp.controls.gamebutton             android:id="@+id/button1"             android:layout_width="0dip"             android:layout_height="fill_parent"             android:layout_weight="1" />

i want little fancier control, have changed derive viewgroup or subclass of viewgroup (currently trying make relativelayout, example). this, disappears.

i added logging see values being passed onsizechanged, , i'm getting 0 height being passed onsizechanged every instance of control no change layout xml (above) works otherwise when derive directly view.

do need add additional hints, params or layout parameters either xml or in code when switching view viewgroup?

you need implement onmeasure() tell toolkit size (you must call setmeasureddimension() @ end of onmeasure().) viewgroup, default, compute size based on children , don't have here, size 0x0.

c# - How to set Z index when using WPF DrawingContext? -

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

(the array 7 rows 9 columns, btw). mov cx, 7; cx = number of rows outer: ; outer loop walk through rows push cx mov cx, 9 mov row, cx ;rows middle: ; middle-loop walk through columns push cx sub cx, 1 ;cx = cx-1 mov column, cx ;columns inner: ;inner loop - compare , exchange column values cmp marray[row*9 + column], marray[row*9 + column+1] xchg marray[row*9 + column+1], marray[row*9 + column] ; compare , exchange values marray table inc column loop inner pop cx loop mid...
