Question

I have a few variables(edit Text and text View) and some buttons,and I want each one of the buttons do something different with the same variables. is there anyway that I won’t need to define all the variables for each onClickListener? I’ve seen this post but I think my question is opposite of that!

As an example think of having a few edit text getting numbers and then some butons that do * , / ,+, – operation on them.

in addition is that possible to use results of an onCliclListener in another one? How?

Answer 1

Implement onClickListener in your activity.

Declare your variables as field of activity class, like

int x=10;
int y=20;
int result=0;

Set setOnClickListener(this); to each of your button.

in onClick method, do following:

public void onClick(View view)
{

    if(view == btn1)
    {
       result=x+y;
    }
    if(view == btn2)
    {
       result=y-x;
    }
}
