We wish there is a default value attribute in each view of android views or group view in future versions of SDK. but to overcome that, simply before submission, check if the view is empty equal true, then assign a default value

example:

   /* add 0 as default numeric value to a price field when skipped by a user,
                    in order to avoid parsing error of empty or improper format value. */
                    if (Objects.requireNonNull(edPrice.getText()).toString().trim().isEmpty())
                    edPrice.setText("0");

There is the hint feature  You can use the setHint   to set it  or set it in XML  though you probably don t want that  because the XML doesn t  know  the name adress of your user

You can use text property in your xml file for particular Edittext fields  For example     lt EditText     android id    id ET User      android layout width  wrap content      android layout height  wrap content      android text  yourusername   gt    like this all Edittext fields contains text whatever u want if  user wants to  change particular Edittext field he remove older text and enter his new text   In Another way just you get the particular Edittext field id in activity class and set text to that one   Another way   programmatically  Example   EditText username  EditText findViewById R id ET User    username setText  jack
