我目前有一个包含多个编辑文字的大型活动＆amp;图像按钮。 但是，当我为导航添加滑动手势时，所有小部件都不会引发任何点击...
有人已经面临这个问题并有解决方案吗？
感谢。
编辑添加代码源：
这是带有表单的线性布局，视图非常大，所以我只是将代码发布到第一个edittext。
<!-- Form -->

这是我的活动，我没有删除代码，因为我不知道我写的东西是否可以处理这个错误。

答案 0 :(得分：1)
你压倒DispatchTouchEvent＆amp;它不会将事件分派给窗口元素，因为它不会调用它的基本DispatchTouchEvent构造函数。尝试
public override bool DispatchTouchEvent(MotionEvent ev)
{
_gestureDetector.OnTouchEvent(ev);
return base.DispatchTouchEvent(ev);
}
