Not show keyboard capture with window flag FLAG_SECURE

问题

I am adding the following flag to my app:

getWindow().addFlags(WindowManager.LayoutParams.FLAG_SECURE);

Sadly the keyboard is still visible and I can still see what the user is inputting when I watch thew playback of the screen recording.

Any idea, how I can stop to the keyboard being captured?

Edit: I don't want to hide the soft keyboard as the user has to enter private information in text fields.
