Overriding android:ellipsize on ActionBar subtitle

Image
By User



My activity makes use of the ActionBar.setSubtitle function to display the currently displayed file system location's full path. This means that the substring towards the end of the subtitle is more relevant than the beginning, so I thought I would override the ActionBar style to ellipsize text at the start, rather than the end, like so:





res/values/themes.xml







<style name="Theme.Holo" parent="android:Theme.Holo">

    <!-- Action bar styles -->

    <item name="android:actionBarStyle">@style/Widget.Holo.ActionBar</item>

</style>







res/values/styles.xml







<style name="Widget.Holo.ActionBar" parent="@android:style/Widget.Holo.ActionBar">

    <item name="android:subtitleTextStyle">@style/TextAppearance.Holo.Widget.ActionBar.Subtitle</item>

</style>



<style name="TextAppearance.Holo.Widget.ActionBar.Subtitle"

       parent="@android:style/TextAppearance.Holo.Widget.ActionBar.Subtitle">

    <item name="android:ellipsize">start</item>

</style>







When I install this onto my ICS device (Nexus S), the text is still (incorrectly) ellipsized at the end. If I modify my version of TextAppearance.Holo.Widget.ActionBar.Subtitle to include an item for android:textSize , the subtitle's text size does get altered accordingly, so it would seem as if I am poking around in the right style; I just can't figure out why it's not honouring my android:ellipsize override.





To put all this into a question format: how can I override, using styles/themes, the android:ellipsize property of the subtitle view in the ActionBar ?

Why is this Javascript much *slower* than its jQuery equivalent?

By User
I have a HTML list of about 500 items and a "filter" box above it. I started by using jQuery to filter the list when I typed a letter (timing code added later): $('#filter').keyup( function() { var jqStart = (new Date).getTime(); var search = $(this).val().toLowerCase(); var $list = $('ul.ablist > li'); $list.each( function() { if ( $(this).text().toLowerCase().indexOf(search) === -1 ) $(this).hide(); else $(this).show(); } ); console.log('Time: ' + ((new Date).getTime() - jqStart)); } ); However, there was a couple of seconds delay after typing each letter (particularly the first letter). So I thought it may be slightly quicker if I used plain Javascript (I read recently that jQuery's each function is particularly slow). Here's my JS equivalent: document.getElementById('filter').addEventListener( 'keyup', function () { var jsStart = (new Date).getTime()...

Is it possible to have IF statement in an Echo statement in PHP

By User
Thanks in advance. I did look at the other questions/answers that were similar and didn't find exactly what I was looking for. I'm trying to do this, am I on the right path? echo " <div id='tabs-".$match."'> <textarea id='".$match."' name='".$match."'>". if ($COLUMN_NAME === $match) { echo $FIELD_WITH_COLUMN_NAME; } else { } ."</textarea> <script type='text/javascript'> CKEDITOR.replace( '".$match."' ); </script> </div>"; I am getting the following error message in the browser: Parse error: syntax error, unexpected T_IF Please let me know if this is the right way to go about nesting an IF statement inside an echo. Thank you.
