Validate blank fields

I have a form with 3 fields to be filled and stored in bank. One of the fields is filled by the system the rest by the user.

boolean isInserted = myDb.insertData(editNome.getText().toString(),
                                editVeiculo.getText().toString(),
                                editVelmax);

As above, I created a Boolean variable named isInserted to return true or false, but as the variable editVelmax is always filled it is always returning true even the fields editName and editVeiculo blank. How do I validate these two fields as well?

Check the values before persisting the information: 

boolean isInserted = false;
String nome = editNome.getText();
String veiculo = editVeiculo.getText();

if(nome != null && veiculo != null && !nome.trim().isEmpty() && !veiculo.trim().isEmpty()){
     isInserted = myDb.insertData(nome, veiculo, editVelmax);
}
