android - View images from a website in app? -

-

in android app have see images website. on website images sorted in categories , can voted. app should see (when select category) pictures category , votes each picture.

i have never done , have no idea how start this. can give me idea? idea welcome..

thanks in advance.

first, should try retrieve list of images have display. can accomplished retrieving page of wanted category on website (see http://developer.android.com/reference/org/apache/http/client/methods/httpget.html) , parsing (you can use may ways that, let choose 1 want apply).

the next step, in opinion, create custom adapter in order keep data. so, create class extends baseadapter, , manage make contain list of drawable (arraylist<drawable>) , list of urls (arraylist<string>). also, provide method allows add url adapter.

when url added, create new thread (or asynctask) retrieve image (in order use httpget here too) , create drawable (using drawable.createfromstream). once download done, notify handler add url arraylist<string>, , drawable have created in thread arraylist<drawable>. don't forget synchronization if use method.

once adapter complete, use method want display content. could, example, use gallery view (see http://developer.android.com/guide/tutorials/views/hello-gallery.html).

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...
