推荐答案

您应该能够实现<一个href=\"http://developer.android.com/reference/android/view/ViewGroup.html#onInterceptTouchEvent%28android.view.MotionEvent%29\"相对=nofollow>中的LinearLayout的自定义子类onInterceptTouchEvent 的方法来达到这种效果。从文档：

You should be able to implement the onInterceptTouchEvent method in a custom subclass of LinearLayout to achieve that effect. From the documentation:

公共布​​尔的 onInterceptTouchEvent （MotionEvent EV）

public boolean onInterceptTouchEvent (MotionEvent ev)

实现此方法可拦截所有触摸屏移动事件。这可以让你观看赛事，他们被分派到你的孩子，并采取目前的姿态所有权的任何一点。

Implement this method to intercept all touch screen motion events. This allows you to watch events as they are dispatched to your children, and take ownership of the current gesture at any point.
