如何以编程方式禁用屏幕锁定密码.

Question

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,则会失败.

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"？

Answer 1

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.
