You may use bringToFrontmethod (http://developer.android.com/reference/android/view/View.html). Also please read this — Defining Z order of views of RelativeLayout in Android. I think this should help.
您可以使用becomeToFront方法（http://developer.android.com/reference/android/view/View.html）。另请阅读此 —在 Android 中定义 RelativeLayout 视图的 Z 顺序。我认为这应该有所帮助。

To both summarize and yet clarify:
总结并澄清：
yourView.bringToFront();
