我正在为游戏创建一个简单的菜单。当玩家点击一个选项时，选项列表移动到一侧，为子菜单腾出空间淡入。
gameModeChoose包含在选择选项后移动到一侧的选项，subMenu是淡入的子菜单（以编程方式创建）。要将子菜单右侧的选项列表对齐，我正在使用subMenuParams.addRule(RelativeLayout.RIGHT_OF,R.id.game_mode_choose)和mainFrame.addView(subMenu,subMenuParams)，但是这会将子菜单与之前的选项列表对齐/ strong>它移动为子菜单腾出空间。我怀疑问题可能正在发生，因为我正在使用gameModeChoose.animate().translationXBy(...)移动选项列表，但我不知道如何调试它。我在选项列表移动后尝试使用addRule(...)，并尝试使用subMenu.setLayoutParams(...)尝试更新视图，但这些都不起作用。
我描述的问题发生在我发表评论的onAnimationEnd(Animator animation)方法中。
