将触摸事件传递给父视图 [英] Passing touch events to the parent view

问题描述

我有一个自定义的 ViewSwitcher，我在其中实现了触摸事件，所以我可以使用触摸屏滚动屏幕.

I have a custom ViewSwitcher in which I implemented touch events so I am able to scroll through screens using the touchscreen.

我的布局层次结构如下所示:

My layout hierarchy looks like this:

<ViewSwitcher>

    <LinearLayout>
        <ListView />
    </LinearLayout>

    <LinearLayout>
        <ListView />
    </LinearLayout>

</ViewSwitcher>

现在，问题是触摸事件正在被ListViews 并且我无法切换视图.当我使用它时它工作正常没有 ListViews.我需要能够滚动浏览查看并滚动 ListView.

Now, the problem is that the touch events are being consumed by the ListViews and I am not able to switch the views. It works fine when I don't have the ListViews. I need to be able to scroll through the views and scroll the ListView.

我该如何解决这个问题?

How do I solve this?

EDIT:我还需要 ListView 项可以点击.

EDIT: I also need the ListView items to be clickable.

提前致谢！

推荐答案

感谢大家的回答.但我能够以更简单的方式弄清楚它.由于我的 ViewSwitcher 没有检测到触摸事件，我拦截了触摸事件，调用了 onTouchEvent() 并返回了 false.这里:

Thank you everyone for answering the question. But I was able to figure it out in a much simpler manner. Since my ViewSwitcher wasn't detecting the touch event, I intercepted the touch event, called the onTouchEvent() and returned false. Here:

@Override
public boolean onInterceptTouchEvent(MotionEvent ev)
{
    onTouchEvent(ev);
    return false;
}

通过覆盖onInterceptTouchEvent()，我能够拦截活动中的触摸事件.然后我在 ViewSwitcher 中调用了 onTouchEvent() 来处理 ListViews 的切换.最后通过返回 false，确保 ViewGroup 不会消耗该事件.

By overriding the onInterceptTouchEvent(), I was able to intercept the touch event in the activity. Then I called the onTouchEvent() in the ViewSwitcher which handles the switching of the ListViews. And finally by returning false, it makes sure that the ViewGroup doesn't consume the event.
