Full-Screen Android Layout with 2 Rows -

-

i'm complete beginner android development , i'm trying feel should simple doesn't seem (for me, anyway). awesome ascii art below demonstrates layout i'm trying achieve:

--------------------- |                   | |                   | |                   | |                   | |                   | |     main view     | |                   | |                   | |                   | |                   | |                   | --------------------- ||btn a|     |btn b|| ---------------------

the whole layout should fill screen bottom row being docked bottom of screen (gravity?) , top row taking rest of screen , should fluid (i.e. if device orientation changed this:

--------------------------- |                         | |                         | |        main view        | |                         | |                         | --------------------------- ||btn a|           |btn b|| ---------------------------

if working in html done table element, 2 tr elements (the first rowspan of 2) , couple of td elements in second row (the second having align value set right). (for web ui guys reading this, use div elements , css layout in practice).

so, problem getting first row fill available height. write simple algorithm in java code prefer work xml layout. there easy way this? code follows:

<tablelayout xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/layout"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:stretchcolumns="1">     <tablerow>         <webview android:id="@+id/site"             android:layout_span="3" />     </tablerow>     <tablerow>         <button android:id="@+id/back"             android:text="btn a" />         <view android:id="@+id/filler" />         <button              aroid:id="@+id/forward"             android:text="btn b" />     </tablerow> </tablelayout>

weight correct choice, try out (tested)

<?xml version="1.0" encoding="utf-8"?> <tablelayout xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/layout"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:stretchcolumns="1">     <linearlayout android:layout_height="fill_parent"                    android:layout_width="fill_parent"                    android:id="@+id/linearlayout2"                    android:layout_weight="1">         <webview android:layout_height="wrap_content"                   android:id="@+id/site"                   android:layout_width="wrap_content" />     </linearlayout>     <linearlayout android:id="@+id/linearlayout1"                    android:layout_width="wrap_content"                    android:layout_height="wrap_content">         <button android:layout_weight="2"                  android:text="button"                  android:id="@+id/button1"                  android:layout_width="fill_parent"                  android:layout_height="fill_parent"></button>         <button android:layout_weight="2"                  android:text="button"                  android:id="@+id/button2"                  android:layout_width="fill_parent"                  android:layout_height="fill_parent"></button>     </linearlayout> </tablelayout>

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.

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...
