actionscript 3 - How to refresh itemrenderer in flex -

-

i have developed flex application contains itemrenderer displays list of items. problem if select item background gets highlighted , if go page , come same page again, item had selected before still highlighted. there solution can refresh itemrenderer clear highlighted background every time when open page?

one itemrenderer instance (checkbox , label) highlighted

so sounds when "go page , come back" you're navigating other screen in app , returning screen has list. item says selected because view being re-used. it's not new view being created scratch...

to remove selection list, can set selectedindex of list -1, or perhaps set selecteditem of list null (or perhaps undefined docs state). can either of these things right before navigate next screen, or when navigate list.

there's few more ways solve this:

  • don't re-use view
  • reset dataprovider on list when navigate back
  • etc...

but setting selectedindex or selecteditem efficient method.

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
