Question

我在这个应用程序中有几个表单，奇怪的是下面的XML并没有让键盘显示每个TextInputEditText的NEXT按钮。

我在底部添加了一个屏幕截图。单击任何TextInput字段，不会显示键盘中的下一个按钮。这令人难以置信！

修改地址确实显示键盘上的NEXT按钮。另一个人不喜欢疯狂。

Answer 1

android:digits参数会中断android:nextFocusDown

android：digits =＆＃34; abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ - ＆＃39;`。＆＃34;

我已经报告了错误https://issuetracker.google.com/issues/74175708

为什么NEXT不会在键盘上显示此UI（NextFocusDown）？
