Not converting INTEGER to String

Question

Good Afternoon, my application has the function of monitoring virtually a football game, and it contains a button that saves the name of the team and the number of goals that the team made... Only when I click the save button it says that the application has stopped, I took a look at Logcat and apparently shows that it is not converting my INTEGER to String, I did the process 'Integer.parseInt' only that it is giving error.

class:

        DbHelper dbhelp = new DbHelper(this);
        dbhelp.insertResultado(inserir);


        finish();
    }

    public void SalvarVermelho (View view){

    }

    public void SalvarAmarelo (View view){
        Intent amarelo = new Intent(this, CartaoAmarelo.class);
        startActivity(amarelo);
    }


    public void ress (View view){
        Intent result = new Intent(this, ResultSimples.class);
        startActivity(result);
    }
}

valueOne and valueDouble it shows as number....

Answer 1

See the cause of the error:

Caused by: java.lang.NumberFormatException: Invalid int: " 2"

There is a space before the number.

Before converting use the method Trim() of the string class to delete any spaces.

inserir.setValorUm(Integer.parseInt(valorOne.getText().toString().trim()));
