i have created a getter and setter class as follow:

public class LayoutClass {

private boolean layoutstatus;

    public void setlayoutStatus(boolean layoutstatus)
    {
        this.layoutstatus=layoutstatus;
    }
    public boolean getlayoutStatus()
    {
        return this.layoutstatus;
    }

    public void setlayoutstring(String layoutstring)
    {
        this.layoutstring=layoutstring;
    }
    public String getlayoutstring()
    {
        return this.layoutstring;
    }
}

and a class for store data in arraylist as given below:

public class LayoutListClass {
     public static final ArrayList<LayoutClass> layoutList = new ArrayList<LayoutClass>();

}

i have added the value in a activity as folow:

LayoutClass layoutobj=new LayoutClass();
layoutobj.setlayoutstring("test1");
layoutobj.setlayoutStatus(true);
LayoutListClass.layoutList.add(layoutobj);      

layoutobj.setlayoutstring("test2");
layoutobj.setlayoutStatus(true);
LayoutListClass.layoutList.add(layoutobj);


layoutobj.setlayoutstring("test3");
layoutobj.setlayoutStatus(false);
LayoutListClass.layoutList.add(layoutobj);

and when i am going to get the value:

for(LayoutClass layoutobj:LayoutListClass.layoutList)
            {
                Log.i("Layout "+g,"->"+layoutobj.getlayoutstring()+" Status = "+layoutobj.getlayoutStatus());

            }

i am only able to getting the last value "test3" all three times.

i want to know how to get the proper value or how to store the object of arraylist and used it later.

LayoutClass layoutobj=new LayoutClass();
layoutobj.setlayoutstring("test");
layoutobj.setlayoutStatus(true);

LayoutClass layoutobj1=new LayoutClass();
layoutobj1.setlayoutstring("test1");
layoutobj1.setlayoutStatus(true);

LayoutClass layoutobj2=new LayoutClass();
layoutobj2.setlayoutstring("test2");
layoutobj2.setlayoutStatus(false);

LayoutListClass.layoutList.add(layoutobj);
LayoutListClass.layoutList.add(layoutobj1);
LayoutListClass.layoutList.add(layoutobj2);

Do it like this.

Why you are getting the last value, because you are changing the value of a single object you need to create object for every position in Arraylist
