我有一个场景过渡,用于将一种布局动画化为另一种布局。进入动画效果很好,而退出动画看起来好像视图被目标布局的边界所裁剪。我该如何解决?
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val sceneRoot = findViewById<ViewGroup>(R.id.scene_root)
val fabCompactViewGroup = layoutInflater.inflate(R.layout.fab_menu_compact, sceneRoot, false) as ViewGroup
val fabExpandedViewGroup = layoutInflater.inflate(R.layout.fab_menu_expanded, sceneRoot, false) as ViewGroup
fabCompactScene = Scene(sceneRoot, fabCompactViewGroup)
fabExpandedScene = Scene(sceneRoot, fabExpandedViewGroup)
revealManager = TransitionInflater.from(this).inflateTransition(R.transition.fab_reveal_transition)
dismissManager = TransitionInflater.from(this).inflateTransition(R.transition.fab_dismiss_transition)
currentScene = fabCompactScene
fabCompactScene?.let { TransitionManager.go(it, dismissManager) }
fabCompactViewGroup.findViewById<FloatingActionButton?>(R.id.fab_compact)?.setOnClickListener(this)
fabExpandedViewGroup.findViewById<FloatingActionButton?>(R.id.fab_compact)?.setOnClickListener(this)
fabExpandedViewGroup.findViewById<FloatingActionButton?>(R.id.fab_expanded1)?.setOnClickListener {
Toast.makeText(this, "Expanded 1 Clicked", Toast.LENGTH_SHORT).show()
}
}
override fun onClick(v: View?) {
if(currentScene == fabCompactScene) {
currentScene = fabExpandedScene
fabExpandedScene?.let { TransitionManager.go(it, revealManager) }
} else {
currentScene = fabCompactScene
fabCompactScene?.let { TransitionManager.go(it, dismissManager) }
}
}

发生这种情况是因为动画视图的父级place
。默认情况下,ViewGroup
不会绘制超出父级边界的子级部分。要对其进行修复,请将此行添加到动画视图的父级ViewGroup
ViewGroup
或以编程方式
android:clipChildren="false"
android:clipToPadding="false"
