Buggy source:
@Override public void onItemSelected(AdapterView<?> parent,View view,int position,long id){
  passphraseEditText.setHint("String_Node_Str" + Passphrase.passphraseTypes[position]);
  passphraseConfirmationEditText.setHint("String_Node_Str" + Passphrase.passphraseTypes[position]);

Fixed version (ground truth):
@Override public void onItemSelected(AdapterView<?> parent,View view,int position,long id){
  passphraseEditText.setHint("String_Node_Str" + Passphrase.passphraseTypes[position]);
  passphraseConfirmationEditText.setHint("String_Node_Str" + Passphrase.passphraseTypes[position]);
  selectedPassphrasetype=position;
  if (position == Passphrase.INDEX_PASSPHRASE_TYPE_PASSWORD) {
    setPassphraseItemsEnabled(true);
    setPassphraseItemsVisible(true);
    passphraseEditText.setText("String_Node_Str");
    passphraseConfirmationEditText.setText("String_Node_Str");
    passphraseEditText.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD);
    passphraseConfirmationEditText.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD);
    passphraseEditText.setTransformationMethod(PasswordTransformationMethod.getInstance());
    passphraseConfirmationEditText.setTransformationMethod(PasswordTransformationMethod.getInstance());
    passphraseCard.doExpand();
  }
 else   if (position == Passphrase.INDEX_PASSPHRASE_TYPE_PIN) {
    setPassphraseItemsEnabled(true);
    setPassphraseItemsVisible(true);
    passphraseEditText.setText("String_Node_Str");
    passphraseConfirmationEditText.setText("String_Node_Str");
    passphraseEditText.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD | InputType.TYPE_CLASS_NUMBER);
    passphraseConfirmationEditText.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD | InputType.TYPE_CLASS_NUMBER);
    passphraseEditText.setTransformationMethod(PasswordTransformationMethod.getInstance());
    passphraseConfirmationEditText.setTransformationMethod(PasswordTransformationMethod.getInstance());
    passphraseCard.doExpand();
  }
}
