TextInputLayout username = findViewById(R.id.username);

CodePudding user response：

ClassCastException is a runtime exception raised in Java when we try to improperly cast a class from one type to another.

In most cases -- depending on compiler support -- the resulting view is automatically cast to the target class type. If the target class type is unconstrained, an explicit cast may be necessary.

for example:

EditText editText = (EditText)findViewById(R.id.username);

for more info you can look at here in docs findViewById and TextInputLayout

Try to cast from TextInputLayout to TextInputEditText
