Question

Class-1

public class MyHeader {

private Button button1,button2;

public MyHeader(Activity source) {
   this.button1 = (Button)source.findViewById(R.id.b_one);
   this.button2 = (Button)source.findViewById(R.id.b_two); 
   // ...
   }

public Button getHeaderButtonOne() { return button1; }
// And so on...

class-2

private MyHeader header;
 // ... in onCreate() method
  header = new MyHeader(this);

Using this code, in class 2 I am able to access the button for which I got the id in class1. Now I want to get the onclick event for the button set in class 1 and if i get the button in class 2 I should be able to use the click event also.

Answer 1

Just add a new method in your class-1:

public void clickButton1(){
   button1.performClick();
}

and call it from your class-2 like this:

header.clickButton1();
