Nonsense. This group is very helpful. If you have a uber beginner's
question, ask it at Stack Overflow (www.stackoverflow.com), over there
Google has an official "android" tag and the general idea is beginner
questions go there and more advanced questions go here. Not to say
this ListView question is a beginner's question at all, I don't
believe it is.
Sunil, Regarding your question: are you making sure the ListView you
want a drawing cache of is the currently visible one before you call
getDrawingCache().. Cycle through each of your ListView's displaying
them for a quick second to get its drawing cache.. I have no idea if
this will work, I've never done anything of this sort. You may also be
having issues because your View elements aren't actually drawn until
after your Activity code completes... I ran into a similar problem
trying to calculate the width and height of a View I had just
displayed on screen programatically. The solution is to run a separate
thread to get this info--you add your thread to the Handler's message
list and it will be run after the current thread (your UI thread) is
completed.
Here's a simple example of how to start your thread and add it to the
list:
Runnable myRunnable = new TheNameOfYourRunnableThread();
new Handler().post(myRunnable);
Then to declare your TheNameOfYourRunnableThread() Runnable:
class TheNameOfYourRunnableThread implements Runnable {
// This method is called when the thread runs
public void run() {
// Code to getDrawingCache()
}
}
Hope this helps. As TreKing points out, I'm sorry but I don't have the
time to review your code.
