问题 I've seen older posts and all the answers suggest to clearFocus. I can't do that, because my TimePicker isn't inside a dialog, so I don't know when I should call clearFocus() function and probably it will crash my app if I would try to modify TimePicker after.

问题 Im trying to have an edittext which would prompt a keyboard to pop-up when the user selects the edit text. When the user starts typing, it should fill the edittext with the keystrokes that the user puts in... but once a boolean value changes, then the keystrokes that get put will be different than what the user puts in.
