我从数据库中填充了一个 alerttdialog。我将这些值存储在 中arrayList，将它们转换为字符序列列表，然后将它们设置为我的警报对话框构建器。如图所示：
这是我的数据库中填充的“文本模板”选项的屏幕截图：
例如，当我单击其中一个选项时Call me。它在指定的编辑文本中按应有的方式显示。如果我单击其他选项之一，例如“给我发电子邮件”，则会忽略此选项，只有我的第一个“如果”选项Call me。将如图所示工作：
这让我相信由于某种原因只Call me被添加到我的字符序列数组中，但我不知道为什么。这是我的完整课程。我在longOnClick方法上遇到了这个问题。我在下面的代码中标记了这个问题区域：
