android - 与编辑文本输入类型相关的问题

Question

我有一个输入类型为数字的编辑文本。但是在完成任务后，如果我再次单击编辑文本，输入类型将更改为文本。

大约一秒钟，它会将输入类型显示为数字，很快它就会自动将编辑文本的输入类型更改为文本。即使我点击按键，编辑文本也不会显示任何内容。

我检查了 logcat，我得到了这个:

12-20 00:03:09.747: I/Choreographer(5638): Skipped 308 frames!  The application may be doing too much work on its main thread.
12-19 23:57:39.917: W/IInputConnectionWrapper(5638): getTextBeforeCursor on inactive InputConnection
12-20 00:02:45.917: I/InputAttributes(412): InputType.TYPE_NULL is specified

我查看此链接:getExtractedText on inactive InputConnection warning on android

但是找不到解决办法。如果有人可以帮助我解决这个问题，那将会很有帮助。

这是我的自定义单元格 xml(此编辑文本在 ListView 中):

单击 mExpiryDate 后出现问题。在 mExpiryDate 的点击事件中，布局从不可见状态变为可见状态。

尝试在您的 xml 中使用它。它可能会帮助你，通过禁用数字以外的按钮，如果你想添加更多按钮。

android:digits="0123456789"
