Example 21 with Transition

use of android.transition.Transition in project platform_frameworks_base by android.

the class BackStackRecord method getSharedElementTransition.

Example 22 with Transition

use of android.transition.Transition in project platform_frameworks_base by android.

the class BackStackRecord method addTargets.

/**
     * This method adds views as targets to the transition, but only if the transition
     * doesn't already have a target. It is best for views to contain one View object
     * that does not exist in the view hierarchy (state.nonExistentView) so that
     * when they are removed later, a list match will suffice to remove the targets.
     * Otherwise, if you happened to have targeted the exact views for the transition,
     * the removeTargets call will remove them unexpectedly.
