Android系统用户数据锁定是指，当用户在设备上设置了密码、PIN码或指纹识别时，系统会锁定用户的数据，以防止未经授权的访问。是一个示例代码，可以帮助你解决这个问题：
// Create a new instance of the KeyguardManager class
KeyguardManager keyguardManager = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE);
// Create a new instance of the FingerprintManager class
FingerprintManager fingerprintManager = (FingerprintManager) getSystemService(Context.FINGERPRINT_SERVICE);
// Check if the device has a fingerprint scanner
if (fingerprintManager.isHardwareDetected()) {
// Check if the user has granted permission to use the fingerprint scanner
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.USE_FINGERPRINT) != PackageManager.PERMISSION_GRANTED) {
// Request permission
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.USE_FINGERPRINT}, REQUEST_CODE_FINGERPRINT);
} else {
// Check if the user has enabled fingerprint authentication
if (keyguardManager.isKeyguardSecure()) {
// Show the fingerprint authentication dialog
fingerprintManager.authenticate(null, null, 0, new FingerprintManager.AuthenticationCallback() {
@Override
public void onAuthenticationError(int errorCode, CharSequence errString) {
super.onAuthenticationError(errorCode, errString);
}
@Override
public void onAuthenticationHelp(int helpCode, CharSequence helpString) {
super.onAuthenticationHelp(helpCode, helpString);
}
@Override
public void onAuthenticationSucceeded(FingerprintManager.AuthenticationResult result) {
super.onAuthenticationSucceeded(result);
// Unlock the user data
}
@Override
public void onAuthenticationFailed() {
super.onAuthenticationFailed();
}
}, null);
}
}
