推荐答案

使用指针捕获

只有当包含视图的视图层次结构具有焦点时，它才能请求捕获指针.因此，您应该在视图上有特定的用户操作时请求指针捕获，例如在 onClick()事件期间或在 onWindowFocusChanged()事件处理程序中活动.

A view in your app can request pointer capture only when the view hierarchy that contains it has focus. For this reason, you should request pointer capture when there's a specific user action on the view, such as during an onClick() event, or in the onWindowFocusChanged() event handler of your activity.

要请求捕获指针，请在视图上调用 requestPointerCapture()方法.下面的代码示例演示如何在用户单击视图时请求捕获指针:

To request pointer capture, call the requestPointerCapture() method on the view. The following code example shows how to request pointer capture when the user clicks a view:
