Question

I have a method like:

public String get_Rid_something () {return((EditText)mParent.findViewById(Rid_something)).getText().toString();}

If there is no text in the EditText box, what happens, will there be an exception? Or will toString() just return the null for the string without an exception?

I have a bunch of these, so I’d like to efficiently fix each one so that they would return “0” if the text is null – hopefully without bracketing it with a try…catch construct.

Is there an “if” statement I could put in there to see if the string is null and return “0” if it is? Could I do something like:

if (((EditText)mParent.findViewById(Rid_something)).getText().toString().isEmpty()) {
    return "0"; } else {...}

Any other suggestion of a better way to do this?

TIA!

Answer 1

If the EditText has no contents, it will return a blank string, or a “” In order to return with 0, simply set up an if statement:

EditText editText = (EditText) mParent.findViewById(Rid_something);
String string = editText.getText().toString().trim();
if (string.equals("")) {
    return "0"; 
} else {
    return string;
}

This will return 0 if blank, or the contents if not.
