How To Compare Data(int) In The First And Data(int) In Second Button In Android?

I have a problem where I want to make the comparison the data in button package lynn.calculate.KaunterKalori; import lynn.calculate.KaunterKalori.R; import android.app.Activity; i

Solution 1:

It's a scoping problem, you are declaring int TotalKalori locally in the onClick event.

Declare it like you have done with totalKalori1 and it should work

Solution 2:

Or you can use getTag(); setTag(); to store the variables on the buttons...

Use setTag to the data you want

     myButton.setTag("fun Stuff"); 

Then on the listener just get the tag (you will need to do a type cast):

OnClickListener myListner = newOnClickListener() {
             publicvoidonClick(View view) {
                 doSomethingAwesome(view, (String) view.getTag());
             }
         };

Solution 3:

Declare int TotalKalori only once globally (in the section you declared protected int totalKalori1; protected int totalKalori2;... ) and simply use it for both buttons like: in button1 TotalKalori = calculateTotalKalori(totalKalori1, totalKalori2,totalKalori3); this value is global so button2 already can acess it by simply using TotalKalori where you need and also the comparison portion.
