java - When to create a Panel for CardLayout? -

-

i use cardlayout mvc , try understand, when should create panels used cardlayout.

for example:

a detailpanel view , edit details of dataitem shown, when select dataitem on listpanel. should create , show detailpanel when select dataitem, or should create detailpanel @ start of application , call load method, when select dataitem, , show detailpanel?

currently i'm using cardlayout stack. add panel when need , remove when i'm done editing.

try avoid replacing view components. initially, create of detailpanel possible , update component models in listselectionlistener. use cardlayout variable portion of each detailpanel. it's unlikely creating view have perceptible performance impact; profile see. if find constructing model introduces significant latency, consider swingworker, illustrated here , here.

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
