[android-beginners] Re: EditText to String to int
Don't worry about it. It's like writing a resume or some other document. You sometimes need someone to proofread what you write and sometimes you miss the most obvious things.

[android-beginners] Re: EditText to String to int
You said "edittext", but what is edittext? It sounds like the name
you've given to an EditText, but I see btnAddCost.getText().toString()
which kinda makes me wonder if it's really a button you are trying to
get the text from. Are you sure that value is a number?

[android-beginners] Re: EditText to String to int
Ok I rearranged my code a bit and put the triggered code into public
voids. Here is the code that fires my function:
final String value = btnAddCost.getText().toString();
addCost(Integer.parseInt(value));
and here is the addCost() function:
public int totalCost=0;
public void addCost(int cost)
{
final TextView txtTotalCost;
txtTotalCost = (TextView) findViewById(R.id.txtTotalCost);
totalCost = totalCost + cost;
txtTotalCost.setText("$"+totalCost);
}
this all compiles fine, has no errors, and no warnings; yet when I
enter a valid integer, (edittext is numeric only) it crashes the app.
Any ideas? I don't really know how to use the debugger yet.

[android-beginners] Re: EditText to String to int
The message seems a bit different from what I'd expect, but I think
it's a matter of using final. Final for a primitive means you can't
change it (and if it were an object, it means you can't reassign to a
different object, but you can change the internal state of it). So,
probably define totalCost as a member variable of your class and drop
the final keyword.
