为 Android 自定义生物识别提示

Question

I have an implementation of the Fingerprint Biometric authentication for Android which works pretty much as described by the documentation. I am trying to remove the close button aka the "setNegativeButtonText" value. This will make the biometric auth a requirement instead of an option.

Is it possible to do this?

Answer 1

BiometricPrompt does not allow that. So you won't be able to make the system-provided biometric prompt non-cancelable. But you can detect whenever user cancels the dialog.

You can use that cancel button as UsePassword instead with

setAllowedAuthenticators
