有什么方法可以让我们了解指纹认证的指纹细节？

Question

我正在开发一个应用程序，我想在那个应用程序中添加一些基于指纹登录的限制。

假设我在我的设备中添加了两个指纹。

1) Left hand index finger 
2) Right hand index finger

有什么方法可以让我知道使用了哪个手指进行身份验证，我的意思是说我使用左手食指或右手食指登录我的应用程序。

FingerprintManager.AuthenticationResult

抱歉，您无法注册指纹或访问数据，只能使用以下代码查看注册情况

//Check whether the device has a fingerprint sensor//
    if (!mFingerprintManager.isHardwareDetected()) {
        // If a fingerprint sensor isn’t available, then inform the user that they’ll be unable to use your app’s fingerprint functionality//
        textView.setText("Your device doesn't support fingerprint authentication");
    }
    //Check whether the user has granted your app the USE_FINGERPRINT permission//
    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.USE_FINGERPRINT) != PackageManager.PERMISSION_GRANTED) {
        // If your app doesn't have this permission, then display the following text//
        Toast.makeText(EnterPinActivity.this, "Please enable the fingerprint permission", Toast.LENGTH_LONG).show();
    }

    //Check that the user has registered at least one fingerprint//
    if (!mFingerprintManager.hasEnrolledFingerprints()) {
        // If the user hasn’t configured any fingerprints, then display the following message//
        Toast.makeText(EnterPinActivity.this, "No fingerprint configured. Please register at least one fingerprint in your device's Settings", Toast.LENGTH_LONG).show();
    }

    //Check that the lockscreen is secured//
    if (!mKeyguardManager.isKeyguardSecure()) {
        // If the user hasn’t secured their lockscreen with a PIN password or pattern, then display the following text//
        Toast.makeText(EnterPinActivity.this, "Please enable lockscreen security in your device's Settings", Toast.LENGTH_LONG).show();
    }
