my problem is that when i click next button it will go from first page to second page,

then same again go from second page to third page.

now when i click back button,it will come on second page back and  again when i press it will come on page first.

but  problem is that,now if i click on next button it directly go to page fourth instead of page second.

please help me to solve it.

code:

class Main extends MainScreen
{ 
    ButtonField next1;
    ButtonField prev1;
    public int count;
 
    public Main(int con)
    {  
        count=con;
        setTitle("PAGE"+count);
     
        HorizontalFieldManager hfm1=new HorizontalFieldManager();
       
       
        next1=new ButtonField("Next",ButtonField.CONSUME_CLICK);
        next1.setChangeListener(new FieldChangeListener(){
        public void fieldChanged(Field field,int content){
        if(field==next1)
        {
              count=count+1;
              System.out.println("add"+count);
              UiApplication.getUiApplication().pushScreen(new Main(count));
        }
        }
        });          
        hfm1.add(next1);

             prev1=new ButtonField("Back",ButtonField.CONSUME_CLICK);
             prev1.setChangeListener(new FieldChangeListener(){
             public void fieldChanged(Field field,int content){
             if(field==prev1)
             {
                count=count-1;
                 UiApplication.getUiApplication().popScreen();
             }
             }
             });          
             hfm1.add(prev1);
        }   

}

You don't have to change your variable count...

Replace

    if(field==next1) {
          count=count+1;
          System.out.println("add"+count);
          UiApplication.getUiApplication().pushScreen(new Main(count));
    }

 with

    if(field==next1) {
        UiApplication.getUiApplication().pushScreen(new Main(count + 1));
    }

And replace

    if(field==prev1) {
        count=count-1;
        UiApplication.getUiApplication().popScreen();
    }

with

    if(field==prev1) {
        UiApplication.getUiApplication().popScreen();
    }
