Dear all, I've just met a problem these days. When keyguard is started after booting, I can't see anything at all. However, incredibly, when I drag the unlock button upward (imaging where the position is), I can unlock the screen.
I have used the hierarchy viewer to see the view hierarchy, and see the correct hierarchy of views of my keyguard view. According to this and the correct behavior above, I believe the whole view is running but invisible. Of course I've checked the properties of the ought-to-be-visible objects in the hierarchy viewer and I'm sure they're visible. I just wonder that how could this be?? Is there any hint that you could provide me, please? On the other side, I'd like to discuss the drawing procedure in Android. I'm tracing the code in windowManagerService and the policy of PhoneWindowManager but confused about how it managed the drawing. 1. How does a view hierarchy draw? Is that one view root has a individual surface and each one take the responsibility to draw the whole view? If it's true. Is that mean the cause of my problem is only a problem inside the keyGuardViewManager? 2. What is the role of windowManagerService in drawing? Thanks for reading above all. Please provide me any possible hint if you have. Alonso -- unsubscribe: android-porting+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-porting
