Android检查是否设置了锁屏

Question

我需要检查锁屏是否有Pin或更安全的东西(密码,指纹等).我能够检查是否有Pin,密码或模式.

KeyguardManager keyguardManager = (KeyguardManager) context.getSystemService(Context.KEYGUARD_SERVICE);
    return keyguardManager.isKeyguardSecure();

我的问题是,我无法检测锁屏是否是一个模式或更低的东西.我试过这个:

        int lockPatternEnable = Settings.Secure.getInt(cr, Settings.Secure.LOCK_PATTERN_ENABLED);

但它已弃用,并引发了一个错误.我也试过这个:

            long mode2 = Settings.Secure.getLong(contentResolver, "lockscreen.password_type");

但这也以SecurityException结束.

有没有办法检测锁屏是否有针(或更高)或锁定模式或更低？KeyguardManager以这种方式对我没用:/

任何帮助表示赞赏!谢谢!

第一个错误是:

               Caused by: java.lang.SecurityException: Settings.Secure.lock_pattern_autolock is deprecated and no longer accessible. See API documentation for potential replacements.

第二个的例外是:W/System.err:android.provider.Settings $ SettingNotFoundException:lockscreen.password_type

当您使用Marshmallow或更高版本的设备时,会出现错误(https://developer.android.com/reference/android/provider/Settings.Secure.html)

我这样做:(灵感来自https://gist.github.com/doridori/54c32c66ef4f4e34300f)

public boolean isDeviceScreenLocked() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        return isDeviceLocked();
    } else {
        return isPatternSet() || isPassOrPinSet();
    }
}

/**
 * @return true if pattern set, false if not (or if an issue when checking)
 */
private boolean isPatternSet() {
    ContentResolver cr = context.getContentResolver();
    try {
        int lockPatternEnable = Settings.Secure.getInt(cr, Settings.Secure.LOCK_PATTERN_ENABLED);
        return lockPatternEnable == 1;
    } catch (Settings.SettingNotFoundException e) {
        return false;
    }
}

/**
 * @return true if pass or pin set
 */
private boolean isPassOrPinSet() {
    KeyguardManager keyguardManager = (KeyguardManager) context.getSystemService(Context.KEYGUARD_SERVICE); //api 16+
    return keyguardManager.isKeyguardSecure();
}

/**
 * @return true if pass or pin or pattern locks screen
 */
@TargetApi(23)
private boolean isDeviceLocked() {
    KeyguardManager keyguardManager = (KeyguardManager) context.getSystemService(Context.KEYGUARD_SERVICE); //api 23+
    return keyguardManager.isDeviceSecure();
}
