我正在使用来自ViewPager(在调用活动中)的Activity转换以及共享元素和内容转换.重新进入调用活动时,我遇到了这个崩溃:
java.lang.NullPointerException: Attempt to invoke virtual method 'void android.os.ResultReceiver.send(int, android.os.Bundle)' on a null object reference at android.app.EnterTransitionCoordinator.sendSharedElementDestination(EnterTransitionCoordinator.java:199) at android.app.EnterTransitionCoordinator.viewsReady(EnterTransitionCoordinator.java:123) at android.app.EnterTransitionCoordinator$2.onPreDraw(EnterTransitionCoordinator.java:148) at android.view.ViewTreeObserver.dispatchOnPreDraw(ViewTreeObserver.java:895) at android.view.ViewRootImpl.performTraversals(ViewRootImpl.java:2153) at android.view.ViewRootImpl.doTraversal(ViewRootImpl.java:1180) at android.view.ViewRootImpl$TraversalRunnable.run(ViewRootImpl.java:6558) at android.view.Choreographer$CallbackRecord.run(Choreographer.java:777) at android.view.Choreographer.doCallbacks(Choreographer.java:590) at android.view.Choreographer.doFrame(Choreographer.java:560) at android.view.Choreographer$FrameDisplayEventReceiver.run(Choreographer.java:763) at android.os.Handler.handleCallback(Handler.java:739) at android.os.Handler.dispatchMessage(Handler.java:95) at android.os.Looper.loop(Looper.java:145) at android.app.ActivityThread.main(ActivityThread.java:5832) at java.lang.reflect.Method.invoke(Native Method) at java.lang.reflect.Method.invoke(Method.java:372) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1399)
此外,一旦返回,屏幕开始闪烁,白色屏幕闪烁.
这是我的过渡标志:
- true
- true
- false
我尝试在Calling和Called活动中设置Enter/Exit转换,但没有运气.
