我的应用程序包含用于登录的用户身份验证（包括密码/图案、指纹解锁），这取决于设备安全性。我正在使用生物识别管理器来检测设备是否使用BiometricManager支持指纹，并使用isDeviceSecure()检查设备是否受到保护。我需要检测在哪种模式下移动设备受到保护，无论是针/图案、带指纹的针/图案、带面部解锁的针/图案还是所有三种模式（针/图案、面部解锁、指纹）。

这是检测设置的锁类型的代码

将库添加到build.gradle

implementation 'androidx.biometric:biometric:1.0.0-beta01'

并将此代码添加到您的活动中

KeyguardManager keyguardManager = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE);
boolean keyguardSecure = keyguardManager.isKeyguardSecure();
Log.e("---", "checkSecurityTypes: keyguardLocked - " + keyguardSecure);//true = pin/pattern

int i = BiometricManager.from(this).canAuthenticate();
Log.e("---", "checkSecurityTypes: " + i);//true 0 = pin/pattern with finger print

switch (i) {
    case BiometricManager.BIOMETRIC_SUCCESS:
        Log.d("MY_APP_TAG", "App can authenticate using biometrics.");
        break;
    case BiometricManager.BIOMETRIC_ERROR_NO_HARDWARE:
        Log.e("MY_APP_TAG", "No biometric features available on this device.");
        break;
    case BiometricManager.BIOMETRIC_ERROR_HW_UNAVAILABLE:
        Log.e("MY_APP_TAG", "Biometric features are currently unavailable.");
        break;
    case BiometricManager.BIOMETRIC_ERROR_NONE_ENROLLED:
        // Prompts the user to create credentials that your app accepts.
        break;
}

if (i == 0 && keyguardSecure) {
    //fingerprint is always with pin/pattern/password
    Log.e("---", "checkSecurityTypes: fingerprint is set with pin/pattern");
} else if (keyguardSecure) {
    //true if pin/pattern/password is set
    Log.e("---", "checkSecurityTypes: pin/pattern is set");
}

我们无法检测面部类型。有关更多信息，请参阅此链接
