此程式碼是用的kotlin寫的,java也類比 class AnimUtil { companion object { //平移動畫常量 val TRANS_ENTER_FROM_LEFT = 0//平移動畫左側進入 val TRANS_ENTER_FROM_RIGHT = 1//平移動畫右側進入 val TRANS_EXIT_TO_LEFT = 2//平移動畫退出到左側 val TRANS_EXIT_TO_RIGHT = 3//平移動畫退出到右側 /** * 控制元件的左右平移動畫 */ fun transAnim(context: Context, view: View, transType: Int) { val windowManager = context.getSystemService(Context.WINDOW_SERVICE) as WindowManager val width = windowManager.defaultDisplay.width.toFloat() val animator: ObjectAnimator when (transType) { TRANS_ENTER_FROM_LEFT -> animator = ObjectAnimator.ofFloat(view, "translationX", -width, 0f) TRANS_ENTER_FROM_RIGHT -> animator = ObjectAnimator.ofFloat(view, "translationX", width, 0f) TRANS_EXIT_TO_LEFT -> animator = ObjectAnimator.ofFloat(view, "translationX", 0f, -width) TRANS_EXIT_TO_RIGHT -> animator = ObjectAnimator.ofFloat(view, "translationX", 0f, width) else -> animator = ObjectAnimator.ofFloat(view, "translationX", 0f, -width) } animator.duration = 1000 animator.start() } } }
