Question

我尝试了各种各样的解决方法，但没有一个对我有用。我有一个包含单元格的scrollview，每个单元格都有一个onclicklistener。这些onclicklisteners将视图添加到主视图中，并清除这些子视图onscrollchanged。但如果我尝试在使用fling动作滚动时单击这些单元格，则应用程序崩溃。我尝试在try catch块中添加视图，但异常没有被捕获，应用程序崩溃了..

所以我想在滚动过程中禁用触摸事件。有没有办法做到这一点？崩溃日志如下： -

Answer 1

假设我们有2个事件，event1和event2，并且当调用event1时，它将调用event2。所以你想禁用event2？一般来说，我通常会创建一个变量

isDisable = false

然后覆盖事件2并以某种方式将isDisable传递给event2，假设我们将isDisable传递给event2，然后关于event1的代码应该是

isDisable = true;
call event2
isDisable = false;

并且在event2中，你必须检查isDisable = true或false来决定调用event2做什么。
