在处理滚动型的Andr​​oid触摸事件 [英] Handle touch events in ScrollView Android

问题描述

我想实现拖拽正拖放功能为Android 2.2。我重写onTouchListener每个我的控制。但我所有的控制都在里面滚动型。当我所有的控件都可见，滚动型，然后DRA-N-下降正常工作。但是，当不是所有的控制都在screnn可见光和滚动出现，我不能使用DRA正下降。所有的事件来滚动型和滚动型只进行它们。 Contols没有得到触摸事件，并作为结果，我不能再拖累我的控制。 是否有人知道如何解决这个问题？我想，这应该滚动视图进行自我触摸事件，但随后应此触摸事件传递给孩子的控制。我该怎么办呢？还是有其他的解决方案？ 谢谢你。

I would like to implement drag-n-drop feature for Android 2.2. I override onTouchListener for each my control. But all my controls are inside ScrollView. When all my controls are visible on in ScrollView, then dra-n-drop works fine. But when not all controls are visible on screnn and scrolling appears, I can't use dra-n-drop. All events come to ScrollView and only scrollview proceed them. Contols didn't get touch events and as result, I can't drag my controls. Does anybody know how to resolve this issue? I suppose, that scrollview should proceed self touch event, but then it should transfer this touch event to the children controls. How can I do it? Or any other solutions? Thanks.

推荐答案

使用 mScrollView.requestDisallowInterceptTouchEvent（真）; 来避免滚动型处理touchEvents。另外，作为Ridcully指出 onInterceptTouchEvent处理的触摸事件（）。

Use mScrollView.requestDisallowInterceptTouchEvent(true); to avoid ScrollView to handle touchEvents. Also as Ridcully pointed out handle the touch event in onInterceptTouchEvent().
