from category activity call

Intent it=new Intent(category.this,sub_category.class)
startActivityForResult(it);

similarly

Intent it=new Intent(sub_category.this,list_item.class)
startActivityForResult(it);

and in onClickListener of back button simply finish your activity like

list_item.this.finish();

for going back to previous screen u can call finish() in your current activity. It will remove the current activity from activity Stack and take you to the previous one.
