调用硬件指纹识别功能

效果图

验证是否有指纹识别模块

• 权限 <uses-permission android:name="android.permission.USE_FINGERPRINT" />

private fun checkFingerModule(): Boolean {
        return try {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                (getSystemService(Context.FINGERPRINT_SERVICE) as FingerprintManager).isHardwareDetected
            } else {
                false
            }
        } catch (e: Exception) {
            false
        }
    }

监听识别

mFingerListen = object : FingerprintManagerCompat.AuthenticationCallback(){
    //识别成功
    override fun onAuthenticationSucceeded(){}
    //识别识别
    override fun onAuthenticationFailed() {}
    //错误次数过多
    override fun onAuthenticationError(){}
}
