Move from one type of activity to another

I am trying to transfer a view from one activity to another.

In my first action onButtonClick, I move on to another action using Intent.

I wrote this line setContentView(R.layout.main);in the 1st operation, and also announced graphView.

Now the problem is what I want to fill graphViewin the second step, but this link, i.e. mySimpleXYPlot = (XYPlot) findViewById(R.id.mySimpleXYPlot);is present in the 1st activity.

So how can I use mySimpleXYPlotin 2nd activity?

if i use

 setContentView(R.layout.main);
 mySimpleXYPlot = (XYPlot) findViewById(R.id.mySimpleXYPlot);

in the second step, the whole layout restarts, and I don’t want to do this :(

ANY HELP WILL BE RECOGNIZED!

1st :

public class MyActivity1 extends Activity{
    public static XYPlot mySimpleXYPlot;

    public onCreated(Bundle b){
       setContentView(R.layout.main);
       mySimpleXYPlot = (XYPlot) findViewById(R.id.mySimpleXYPlot);
       // start you 2nd activity from button
    }
}

Activity2

public class MyActivity2 extends Activity{
    private XYPlot mySimpleXYPlot;
    public onCreated(Bundle b){
       setContentView(R.layout.main); 
       mySimpleXYPlot = MyActivity2.mySimpleXYPlot;
       // use mySimpleXYPlot as per your requirement
    }
}
