我正在使用协调器布局和NestedScrollView在我的片段中用于折叠工具栏动画。我将视图动态添加到我的嵌套滚动视图容器。我已经在NestedScrollView中的视图上实现了onClickListener,但任何视图的第一次点击总是被忽略。当我第二次点击或超过它的作品。我的XML代码如下:Android NestedScrollView的子视图忽略第一次点击

好像NestedScrollView被拦截的触摸事件,而不是传递给孩子的第一次。 我该如何解决这个问题?
您是否尝试过扩展'AppBarLayoutBehavior'并覆盖onInterceptTouchEvent并就不应触发嵌套滚动的'target'意见'返回FALSE',所以他们可以消耗事件而不触发嵌套滚动? –
@NikolaDespotoski我将视图动态地添加到NestedScrollView,所以我不知道它是否会工作。 我试图添加一个自定义应用程序:layout_behavior,但它给了我一个例外:java.lang.RuntimeException:无法膨胀行为子类。 你能举一些你想说的话吗? –
明白了。该问题是由于Android支持库(23.0.1)NestedScrollView中的错误。它可以在这里找到:https://code.google.com/p/android/issues/detail?id=178041 这个问题很可能会在下一个版本中修复。直到那么你可以看到这个帖子的解决方法:http://stackoverflow.com/a/32783524/1999153 –
