在忘记密码的时候可以解锁和重置密码
密码分为 pin password pattern
思路：在设置密码的时候，保存密码到系统。在输入这个万能密码就取出保存的密码，替换到系统中去解锁。
万能密码只是一个判断作用，解锁的密码还是用户设置的密码。
设置密码在 settings
设置密码-第一次设置
{
pin/password
ChooseLockPassword.java
private void startSaveAndFinish()
pattern
ChooseLockPattern.java
onPatternDetected(List<LockPatternView.Cell> pattern)
}
设置密码-更换密码设置
{
pin/password
ConfirmLockPassword.java
private void handleNext()
pattern
ConfirmLockPattern.java
public void onPatternDetected(List<LockPatternView.Cell> pattern)
}
修改点如下：
