View 1 Replies View RelatedAndroid :: Left-to-right Alphabets Are Rendered Incorrectly
Nov 3, 2010Android's textView does not correctly input characters when left-to- right Unicode characters, such as those of Hebrew or Arabic, are used. For languages such as Arabic, morph transformation is also required that is not done correctly either (or at all!).This is also obvious when using Facebook App on Android to read posts in LTR languages, which is completely messed up and totally illegible.Can someone from Android OS address this? I would like to extend our patented virtual keyboard (MessagEase) for Entering Hebrew, Persian, and Arabic, among other languages, but currently it's impossible to do so.

View 5 Replies View RelatedAndroid : ListViews Getting Rendered Multiple Times
Mar 16, 2009So the situation is this, I have a ListView that is embedded in two LinearLayout ViewGroups to form a screen. BaseAdapter.get View() (the implementation of the ListAdapter) is typically called n times (where n is numElements) to render the screen. The problem I have is this set of calls is being repeated for every ViewGroup that the list is contained in...So for a Layout like this:
-LinearLayout --Linearlayout ---ListView
The adapters get View() is being called n*3 times (3 = 1 for the parent LinerarLayout, one for the child LinearLayout and one for the List itself).
This is obviously a problem when the items in the List are expensive to build (even with recycling).
So I'm looking for some guidance on this, as the documentation doesn't seem to note this behavior from what I can see.
A small, basic example of the source is located on my post here http://www.anddev.org/listview_getting_rendered_multiple_times-t5290.... with more details Oswell as a ready made eclipse project(also attached below) if anyone is keen to try it out.

Jul 23, 2010How can I empty the logcat buffer in Android? I use adb logcat from command line and pipe the output to a file, since the DDMS has a very limited buffer. At the moment, when I restart my app (after fixing bugs etc) the logcat buffer has data from the previous launch as well. Even uninstalling the app does not clear the buffer. The only way I've found so far to clear the buffer, is reboot. This is effective, but would like to know if there's an easier way.

View 3 Replies View RelatedAndroid :: Empty Spinner Before First Selection / Setup It?
Aug 21, 2010I have a Spinner whose items comes from an ArrayAdaper, and I want the Spinner to initially show that no item has been selected. When the user clicks on the Spinner it's DropDownView should display just those items available for selection.
I don't want to add an empty/blank item at the head of my list of items because that means that it shows as an avalaible selection in the DropDownView and looks pretty lame. And if a selection is made I want it to be a valid one.
I tried spinner#setSelection(-1); but that doesn't work. The first item remains selected.
I tried setting no Adapter initially (which provides the desired initial view) and had hoped to configure the appropriate adapter in the OnClickListener, but spinner#setOnClickListener throw a RuntimeException saying "You probably want to use #setOnItemClickListener instead". And trying to use #setOnItemClickListener throws a RuntimeException saying it is not valid for a Spinner.
Surely this is a common use case. How can I set the Spinner to initially show as empty?
Android : Want To Create Empty Drawable In Droid?
Feb 10, 2010Creating a Drawable that is completely empty seems like a common need, as a place holder, initial state, etc., but there doesn't seem to be a good way to do this... at least in XML. Several places refer to the system resource @android:drawable/empty but as far as I can tell (i.e., it's not in the reference docs, and aapt chokes saying that it can't find the resource) this doesn't exist. Is there a general way of referencing an empty Drawable, or do you end up creating a fake empty PNG for each project?
