onFocusChange 不从视图寻呼机中响应
onFocusChange Doesnt respond from within a view pager
重新发布这个，因为我最初发布它时标题错误，所以它在没有问题的情况下丢失了。
我正在创建一个小型时间表应用程序，目前正在创建一个带有一些选项卡的屏幕。每个选项卡都是一个单独的片段，每个选项卡中都有 20 个编辑文本。我的目标是，如果用户输入其中一个编辑文本，然后单击它并且焦点丢失，则将文本从编辑文本字段发送到主 activity。然后，当单击确认按钮时，编辑文本中的任何文本都会保存到 SQLite 数据库中。
我的问题是焦点侦听器似乎不起作用。
这是片段的代码之一：
