Question

I use following method to get var from another class. However, firstView receives always null value. Why? Thanks

Main class

private String view1 = null;

//...when onCreate view1 is checked that set properly

public String getView1() {

     return view1;   
 }

second class

TabBar_Activity mainRef = new TabBar_Activity();

firstView = mainRef.getView1();

Answer 1

Right behavior because when you getView using getView1() method you are creating new mainRef object of TabBar_Activity. And in that you have just declared String view1 = null. If you want to get setter view1 value then use the object which you are using for setter view1 value in onCreate() of activity not new object.
