title: Disable DONE in soft keyboard until minimum number of characters are typed in edit text
body: <p>I need to keep the <strong>DONE</strong> button (imeOptions-->IME_ACTION_DONE) on android's system softboard disabled until the minimum number of characters are entered in the edit text. Any suggestions?</p>
  
  <p><strong>Note:</strong> Minimum number of characters is just one such validation that needs to be performed on the edittext user input. So until the user entered text pass through all the validations the DONE needs to be kept disabled preventing user from navigating to the next step. </p>
  
  <p>Thanks</p>
