应用程序在按钮点击通话服务上崩溃

Question

我正在做一个批量重命名器，当我在选择文件后单击重命名按钮时，它应该在显示通知时调用后台服务来重命名它，但该应用程序在单击时崩溃。 我在Android 5.0上测试 我尝试在开始时添加祝酒消息，但在此之前也崩溃了 我认为它会在执行按钮单击事件之前崩溃

Answer 1

该问题很可能是由以下行引起的：for(i in 0..cc)。原因是操作符..创建了一个封闭范围，其中包含cc，因此，如果cc等于列表/数组的大小，则会得到{{ 1}}。为了解决这个问题，您可以简单地将行更改为IndexOutOfBoundsException，因为until函数创建的范围不包含end元素。

Answer 2

在注释中没有Mike要求的堆栈跟踪，我唯一能想到的是您忘记了将按钮与xml按钮的ID链接

findViewById(R.id.button);

类似的东西
