基于compose进行指纹验证

点击按钮进行验证

Button(onClick = {var passed = falseval biometic = BiometricPrompt.Builder(applicationContext).setTitle("使用指纹解锁App").setSubtitle("证明你是手机的主人").setNegativeButton("取消验证", mainExecutor) { dialog, which -> Log.e(TAG, "onCreate: click negative buttton", ) }.build()biometic.authenticate(CancellationSignal(), mainExecutor, object:AuthenticationCallback(){override fun onAuthenticationFailed() {super.onAuthenticationFailed()Log.d(TAG, "onAuthenticationFailed: ")passed = false}override fun onAuthenticationSucceeded(result: BiometricPrompt.AuthenticationResult?) {super.onAuthenticationSucceeded(result)Log.d(TAG, "onAuthenticationSucceeded: ")passed = true}})
}) {Text(text = "指纹解锁")
}
