Hi I'm totally out of my depth but persistently wading and learning as I go. I'm really unfamiliar with the Java paradigm, so please bear with me and don't assume I know anything (because, really, I probably don't :- ( ).
A few questions: 1. Could someone point me to, or explain to me, the intended flow of an Android application? eg. if I want to: "do X; get results from X; then display Y to user; then get input; then do Z" I've gleaned so far that I have my main Activity class, in which I set a listener for X, then call X, and that's the end of that class; Then, when my listener is called, I set a listener for input from the user, and display Y to user, and that's all for that class; then, in yet another new class, I have the code that is called if the user presses the button. Is that right ? Seems rather disjoint, and coming from a perl/python background I'm used to systematic flow: "Do X, then display content to user, then loop or block until user enters", so please correct my thinking above if it's erroneous. 2. I have a class "extends Activity" which is the first class of my application. I then want to display a list, and have a class that "extends ListActivity". The ListActivity class is called from a BroadcastReceiver (basically, I'm scanning SSIDs, the listener is called when scan is complete, and then I want to display a list of SSIDs to the user for selection). When I attempt to transfer to a method inside the ListActivity class, my program crashes; I understand that this is due to the different type of view (from TextView to ListView, I suspect). I also have the feeling that I need to set an intent to transition from the first class type to the second... however I don't have sufficient knowledge/background/experience to understand how to get this done (My attempt to create an intent and call startActivity failed because startActivity is not available from within a BroadcastReceiver class) ... :-o Many thanks Gary --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
