Android bringToFront() 查看 API <= 16

Question

当我测试我的应用程序时，我意识到如果我使用 API <= 16 的设备，方法 bringToFront() 将不起作用!我如何为小于 16 的 API 执行此操作？当我触摸一个 View 时，我需要将它带到前面!使用 API 17 或更高版本时，bringToFront() 有效。

谢谢

public void bringToFront () Added in API level 1

Change the view's z order in the tree, so it's on top of other sibling views. This ordering change may affect layout, if the parent container uses an order-dependent layout scheme (e.g., LinearLayout). Prior to KITKAT this method should be followed by calls to requestLayout() and invalidate() on the view's parent to force the parent to redraw with the new child ordering.
