I have a question regarding the storage of value from EditText to attributes of type int of a class. For attributes of type String I do this:
objEquipamento.setMarcaModelo(edtMarcaModelo.getText().toString());
But when my attribute is of type int ? and I want to get a number?
do I have to convert the value or does some method exist for int ?
Use Integer.html#parseInt :
objEquipamento.setMarcaModelo(Integer.ParseInt(edtMarcaModelo.getText().toString().trim()));
If Integer.html#parseInt is unable to perform the conversion, an exception NumberFormatException is released, if you prefer to return a default value instead, do:
public static int MyParseInt(String texto, int valorPadrao) {
try {
return Integer.parseInt(texto);
}
catch (NumberFormatException e) {
return valorPadrao;
}
}
Use this:
objEquipamento.setMarcaModelo(MyParseInt(edtMarcaModelo.getText().toString().trim(), 0));
For double , use Double.html#parseDouble .
You will have to use the Integer.ParseInt () as follows:
try{
objEquipamento.setMarcaModelo(Integer.ParseInt(edtMarcaModelo.getText().toString()));
} catch (NumberFormatException e) {
//erro ao converter
}
It is important that you put the treatment and force the user to actually type an Integer as follows in the xml:
<EditText android:numeric="integer" ..../>
You can use parseInt instead, but since it is an editText, a non-numeric character can be entered, causing an exception, so this needs to be handled
