675,675 | 675,676 | MediaController positioning over VideoView | <p>I have a VideoView that takes up the top half of the Activity in portrait orientation with the bottom half of the screen showing some images and text. I am playing a rtsp video stream in the video view when the Activity starts. I have attached a MediaController to the VideoView via the following code:</p>
<pre><code> MediaController controller = new MediaController(this);
controller.setAnchorView(this.videoView);
controller.setMediaPlayer(this.videoView);
this.videoView.setMediaController(controller);
</code></pre>
<p>When I tap the VideoView to bring up the MediaController on the screen I expected the playback controls to appear overlaying the bottom area of the VideoView (the bottom of the MediaController even with the bottom of the VideoView). Instead the MediaController pops up lower down on the screen, overlaying some of the graphics and text I have below the VideoView. </p>
<p>Are there some additional steps I need to take to get the MediaController to appear where I want it to on the screen?</p>

4,834,861 | 4,834,862 | Centering an element to the viewable area with Jquery | <p>I have a huge scrollable area. In one section I have a grid of thumbnails. When clicked, the thumb is cloned and animates out to the center of the screen, but it animates to the center of the entire area, not the area that you are viewing i;e, the area of have scrolled to. How can I get it to animate to the center of the viewable area? JQuery Code is as follows:</p>
<pre><code>var $article = $('#news-articles .news-article').eq(index);
var $articleClone = $article.clone(true); // clone the article for the corresponding link
// Create the expanded item container
var $expandedItem = $('<div>', {
id: 'item-expanded',
css: {
width: 188,
height: 188,
background: '#fff',
position: 'absolute',
zIndex: 999
},
});
$expandedItem.append($img); //Add the cloned image to the expanded item container
$('body').append($expandedItem); //Add the shaded overlay and the expanded item to the body
//Animate the size of the expanded item
$expandedItem.animate({
width: 400,
height: 400,
left: $(window).width()/2,
top: $(window).height()/2,

queue: false,
complete: function() {
animFinished = true;
if (animFinished) {
imageFade();
}
}
});
</code></pre>
<p>Please note that I have tried changing the positioning of $expanded item to 'fixed'. However, this creates a problem as it needs to animate from the position of the clicked thumbnail which I obtain using the thumb's 'offset'. Changing the positioning of $expandedItem causes it to animate from the thumb's position when it is first loaded, not it's current position after the page has been scrolled.</p>
<p>Hope it all makes sense. Any help with this would be greatly appreciated.</p>
<p>Thanks in advance.</p>

<p>However, because we're constantly having to add pages to the site this now means that if I'm half way through developing a big part of the site when I'm required to make a small change elsewhere, I can't publish "website.dll" to the live site because it has all my half finished code in there. How do people deal with this situation?</p>
<p>If I could split the site up into multiple dlls (perhaps based on namespace?) then I could just publish the small part of the site that's changed, leaving the bit I'm still developing on the dev server.</p>

<p>Now, my question is, how can I alter that code (Disregard the bit within the "if choice = 1:" loop) so that each part of that newly broken up string is put into it's own variable?</p>
<p>For example, putting in NaBr would result in the string being broken into "Na" and "Br". I need to put those in separate variables so I can look them up in my CSV file.
Preferably it'd be a kind of generated thing, so if there are 3 elements, like MgSO4, O would be put into a separate variable like Mg and S would be.</p>
<p>If this is unclear, let me know and I'll try and make it a bit more comprehensible... No way of doing so comes to mind currently, though. :(</p>

<p><strong>Thing I tried or come up with but failed</strong>
I tried to check current running process and based on it tried to decide if app is running or not.
Reason for failure: Get app running status as always true since I already had service running in background.</p>
<p><strong>Possible solution but not sure if that possible in android</strong>
1. If we can run service by different name(package name)
2. Set some boolean value to true and false on app start and close respectively. But is this a good approach?</p>

<p>Sorry if I wasn't very descriptive earlier. I try to explain you what exactly I'm trying to acheive.</p>
<p>Whenever user click on notification. I have to do any one out of two option after checking if my app is launched(excluding services since they are always running in the background).
1. If my app is already launched just start the required activity.
2. If app is not launched then I have to launch it and then open the required activity.</p>
<p>e.g
I get a message arrival notification. If my application is launched I have to show inbox otherwise I have to launch my application and then open the inbox.</p>

3,267,425 | 3,267,426 | take this.id as input and output a changed id for input into a new function | <p>I have a jQuery script that manages a submenu. When the user clicks a div, the div changes to active and then the content changes color accordingly. The buttons have an id tag that is the same as the corresponding div tag, with '_button' added. For example the div to change the color of has id tag 'first', then the buttons id tag is 'first_button'.</p>
<p>The code I have now works fine for the buttons, but I'm not sure how to properly plug in the edited id tag to select the appropriate div to make red with the second jQuery call. Right now the code doesn't do anything to the divs, but I don't receive any errors in the console either. I could do it with a series of if/then statements, but that is rather inelegant.</p>

956,897 | 956,898 | UI Widget drawing in order | <p>I have a custom UI Widget library I've created for a game I'm working on. I need to consider drawing order and retro fit it into what I currently have and not sure of the best way to do so. I have a UI class which loads the widgets from an xml file. It stores all widgets in a map where the key is the string name of the widget.</p>
<p>Widgets can hold other Widgets in a parent child relationship (so the Widget class has a map of Widgets where the name is the key again). When I draw I loop through the UI widget map and only call the Widget's Draw() function's that don't have parents (most top level). Within each Widget's Draw() it loops through it's children and calls their Draw() functions.</p>
<p>The question is what would be a good way to have a sort order variable for each widget work with drawing in the order of the sort order variable while keeping the maps, since I like the ease of finding widgets by the string key name?</p>
<p>Any ideas?</p>
