如何以编程方式禁用屏幕锁定密码。(How to disable screen lock password programmatically.)

我的脚本创建密码并锁定手机，但如果我尝试将密码更改为空白，它失败了。

我的锁定脚本：

DevicePolicyManager deviceManager = (DevicePolicyManager)getSystemService(Context.DEVICE_POLICY_SERVICE); ComponentName compName = new ComponentName(MessageService.this, LockAdmin.class); boolean active = deviceManager.isAdminActive(compName); if (active) { deviceManager.setPasswordQuality(compName,DevicePolicyManager.PASSWORD_QUALITY_UNSPECIFIED); deviceManager.setPasswordMinimumLength(compName, 5); boolean result = deviceManager.resetPassword("blablabla", DevicePolicyManager.RESET_PASSWORD_REQUIRE_ENTRY); }

所以我的问题是，如何将密码更改为空白或如何将锁定模式更改为“无”？

My script creates password and locks the phone, but if I try to change password to blank, it fails.

My locking script:

DevicePolicyManager deviceManager = (DevicePolicyManager)getSystemService(Context.DEVICE_POLICY_SERVICE); ComponentName compName = new ComponentName(MessageService.this, LockAdmin.class); boolean active = deviceManager.isAdminActive(compName); if (active) { deviceManager.setPasswordQuality(compName,DevicePolicyManager.PASSWORD_QUALITY_UNSPECIFIED); deviceManager.setPasswordMinimumLength(compName, 5); boolean result = deviceManager.resetPassword("blablabla", DevicePolicyManager.RESET_PASSWORD_REQUIRE_ENTRY); }

So my question is, how could I change password to blank or how could I change locking pattern to "none"?

最满意答案

2分钟后我试过了，

deviceManager.setPasswordMinimumLength(compName, 0); boolean result = deviceManager.resetPassword("", DevicePolicyManager.RESET_PASSWORD_REQUIRE_ENTRY);

它就像一个魅力。

2 minutes later I have tried,

deviceManager.setPasswordMinimumLength(compName, 0); boolean result = deviceManager.resetPassword("", DevicePolicyManager.RESET_PASSWORD_REQUIRE_ENTRY);

And it works like a charm.
