<p>So if the user is rotating the device, onPause() will get called, but I don't want to cancel the task just because of that. I know there's a way to tell the system to not actually destroy my activity on rotation, but is that recommended for this problem?

2,525,280 | 2,525,281 | Converting an ArrayList<HashMap> into a multidimensional List | <p>I have an ArrayList of HashMap elements that has a format of Category, Activity and Time. I.E.</p>
<pre><code>{CATEGORY=Planning, ACTIVITY=Bills, TIME=5}
{CATEGORY=Planning, ACTIVITY=Bills, TIME=7}
{CATEGORY=Planning, ACTIVITY=Meetings, TIME=10}
{CATEGORY=Resources, ACTIVITY=Room1, TIME=15}
....
</code></pre>
<p><i>Take note of the CATEGORY/ACTIVITY pair that is repeated as that can happen in the List</i></p>
<p>I need to be able to convert this List into a multidimensional one. The best way I can think of for how this List needs to look is by writing some pseudocode...please see that at the bottom of the post.</p>
<p>I've thought of several different approaches on how to implement this but I'm quite frankly stuck and frustrated at how to do this. I've thought of taking the inefficient approach of looping through the ArrayList several times in outer and inner loops but I know that wouldn't be good coding practice.</p>
<p>Any suggestions on how I can implement this conversion so I can loop like in the pseudocode below?</p>
<pre><code>For CATEGORY in CATEGORIES {
CategoryTime = 0
Display Category Header
For ACTIVITY in ACTIVITIES {
Activity Time = 0
For TIME_RECORD in ACTIVITY
Add time to activity total time, category total time & grand total
}
Display Activity Total
}
Display Category Total
}
Display Grand Total and rest of information...
</code></pre>
<p><b>Edit</b>
I appreciate all the feedback given for this problem and it appears that really the best way to go is to enhance a class that the ArrayList of HashMap elements is a member of.</p>
<p>I've put in a vote to close this question as has another person as it's too localized. I would appreciate it if some of you other developers would follow suit to close the question. I would delete it but I can't at this point because there are answers to the question.</p>

<p>I can get the view to load by doing this, but I don't like the fact that it happens outside of the scope of the <code>ListItem</code> class. It seems like <code>ListItem</code> should be responsible for loading its own view. From ListViewAdapter.java:</p>

ListItem entry = items.get(position);

LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

title.setText(entry.getTitle());
TextView subtitle = (TextView) convertView.findViewById(R.id.subtitle);
subtitle.setText(entry.getSubtitle());
return convertView;

1,957,753 | 1,957,754 | Hiding Rows Via Drop Down Lists | <p>I have this weird issue with hiding/showing rows of a table via jQuery and drop down lists. Instead of posting back data based on the filters I just want to hide the data not relevant to what's selected in the drop down lists. Here's the snippet:</p>
<pre><code>$().ready(function() {
$("#SupplierID").change(changeme);
$("#BusinessID").change(changeme);
});
function changeme() {
$("table tr").show();
$("table tr td:nth-child(2):not(:contains('" + $("#SupplierID :selected").text() + "'))").parent().hide();
$("table tr td:nth-child(6):not(:contains('" + $("#BusinessID :selected").text() + "'))").parent().hide();
return false;
}
</code></pre>
<p>The problem with it is that SupplierID works fine, but BusinessID only works once a SupplierID has been selected, and not before. If I go into the page and select a BusinessID from the drop down list straight away nothing happens. I <em>have</em> to change the SupplierID drop down list first in order for it to work. Additionally if SupplierID is set to the "All" option (blank value) then the BusinessID drop down list doesn't work.</p>
<p>Any ideas?</p>

<p>It just seems a bit nasty. Any recommendations on how to make this more elegant?</p>

4,857,587 | 4,857,588 | Javascript + dynamic folders | <p>So I have a Javascript function. It is passed a folder name, say "A".
This folder contains 5 images which will be picked randomly.</p>
<p>It works well on the page load, as 1 random image appears. But I want it so that
when the image is clicked, it is randomized again with an image from the same folder. I tried to go about this with the onmousedown, but it returns a broken image link to
file:///C:/Users/StackOverflow/Documents/Website/[object%20HTMLDivElement]/2.jpg </p>
<pre><code> <script type="text/javascript">
// <![CDATA[
function showImage(folder){
var randomNumber=Math.floor(Math.random()*5);
document.write('<img src="'+folder+'/'+randomNumber+'.jpg" onmousedown="showImage('+folder+')">');
}
//]]>
</script>
</code></pre>

2,480,245 | 2,480,246 | PHP : Post get method, need some advice | <p>I am new to php and need to understand how post get method could be useful for my code. My scenario is, I have 3 webpages, 1st webpage is an html form , I am using post method here then I take firstname and last name from form and enter in a sql query(for e.g. <code>$_POST[firstname]</code>) on 2nd webpage which generates some data for me and I am printing that data.</p>
<p>Now I need to pass same parameters to 3rd page which generates some graph based on firstname and lastname entered in 1st HTML form?</p>
<p>How can I persist these values on 3rd php page? I am referencing url for page 3 on page and I believe that is not sufficient, I tried Google search and found out post get could be useful however need some expert advice.</p>
<p>Thanks</p>
