title: android set specific characters as inputType
body: <p>I'm looking for a way to "customize" the <code>inputType</code> of a <code>EditText</code>. The user should enter a date which has the format <code>dd.mm.yyyy</code> (and yes, I don't want to use a date picker). Setting the <code>inputType</code> to <code>numberDecimal</code> allows entering only one point, but I would like to have only the numeric keyboard, not the whole one. Is there an easy way reaching that without writing a custom keyboard?</p>
  
  <p>So basically I just want to use [1,2,3,4,5,6,7,8,9,0,.]</p>
