Question

我从数据库填充alerttdialog。我将这些值存储在arrayList中，将它们转换为charsequence列表，然后将它们设置为我的alertdialog构建器。如图所示：

这是我数据库中填充的“文本模板”选项的屏幕截图：

当我点击我的一个选项时，例如Call me。它在指定的edittext中显示它应该显示。如果我点击其他选项之一，例如“向我发送电子邮件”，则会被忽略，只有我的第一个“if”选项Call me。将如图所示：

这让我相信由于某些原因只有Call me被添加到我的charsequence数组中，但我不确定为什么。这是我的完整课程。我在longOnClick方法中遇到此问题。我在下面的代码中标记了此问题区域：

稍微尴尬但我刚刚意识到我有不同的字符串比较我的IF与存储在charsequence中的字符串，所以它现在正在工作！

选择选项时，ArrayList到charsequence转换问题
