android - listView.setSelection(n); m=listView.getSelectedItemPosition(); //m != n. why? -

Calling the Setting Calling () of ListView is a problem. A lot of people ask about it. There are answers but no one is working. Here's an original scenario that results in unexpected results:

  listView.setSelection (5); // listView is a ListView & gt; = 6 items in the list int sel = listView.getSelectedItemPosition ();    You would expect SL == 5 but in fact it is -1 (which method does not work?) 
 This is a bug and if not, what are the rules Settings and recovery of selected items?   
 
  If you look in the setSelection document, you know:  
  If the currently selected item sets, in Touch mode, the item will not be selected but it will still be deployed appropriately. If the position of the specified selection is less than 0, then the item will be selected at position 0.   
 In this way, it is fully understood that it gives 1 item is not selected even if you run this method when you are in touch mode, As you are most likely.

Integrate flash games in android app? -



    3 is a flash game that I want to integrate into a menu / list in the Android app. So when the user selects the game from the list, the game starts with the help of the Android Flash Player.   Is it better or better with webwave?   Is there any good tutorial?   Thank you! Adobe Flash provides a good way: you can create a breeze for the Android app.    Use this to create your menu and compile three games in your air app.   Here are some tutorial links about how to publish AiI for Android applications and:   PART1: AIR for Android, PART2:   Publication for Android apps: Ai:   I do not believe that the Android Flash Player can be launched with a single intention so far, so using Java Android will not solve it (now ) And   and a third approach Whatever you mentioned, it should work - using the webwave.
