title: Change password mask character to asterisk (*), BUT WITH DELAY
body: <p>Change password mask character to asterisk (*), is not difficult, I saw this post. <a href="https://stackoverflow.com/questions/14051962/change-edittext-password-mask-character-to-asterisk">Change EditText password mask character to asterisk (*)</a></p>
  
  <p>BUT, what I need is, when input the password, for example, input 'a', it will show 'a' at the EditText for one second(default is 1500ms I think). then show the '*'. I need this delay. I can not find any solution. Any help? I check the android source code, it use many internal variable, I can not override it.</p>
