Crash when rotating Activity using ViewFlipper

懵懂的女人 提交于 2019-12-22 01:31:31
问题 I originally had two ListActivity classes. I'm experimenting with having 1 Activity and, using a ViewFlipper, flipping between the two lists. It seems to be working great except for one problem. If I rotate the emulator, I'll randomly get a crash. It doesn't happen every time and I can't figure out a specific workflow to trigger it. This is the error: 01-12 16:28:58.292: WARN/dalvikvm(877): threadid=3: thread exiting with uncaught exception (group=0x4001b188) 01-12 16:28:58.292: ERROR
