Question

i feel dumb for asking this but i have been fighting with this for a day now and i can’t seem to get it working.

So my problem is I want to keep adding 1 to and integer and make it go like ;

1+1=2
2+1=3

That it keeps updating the Integer I have this now;

int val = 1;
int g = 1;

val = g + val;

But it keeps saying its 2 how come?

Thanks.

I’m guessing you put all of your code in your click handler. Instead, put the variable declaration/initialization in the class level and only your addition code in your click handler. Rough code as follows:

public YourActivity extends Activity {
    int val = 1;
    int g = 1;

    @Override
    protected void onCreate (Bundle savedInstanceState) {
        ... //find button in here
        button.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                val = g + val;
            }
        });
    }
}
