title: Decimal separator comma (',') with numberDecimal inputType in EditText
body: <p>The <code>inputType</code> <code>numberDecimal</code> in <code>EditText</code> uses the dot <code>.</code> as decimal separator. In Europe it's common to use  a comma <code>,</code> instead. Even though my locale is set as german the decimal separator is still the <code>.</code></p>
  <p>Is there a way to get the comma as decimal separator?</p>
