In my "FilterChoice" activity, I create the layout dynamically. I create a Radio Group and add Radio Buttons in it depending on the size of an ArrayList. There's a list in my "Filters" activity. The radio buttons are different depending on the filters clicked. When I click "Prices" filter, it views six items on the "FilterChoice" activity. Then pressing back button, when I click "Categories" filter, the checkedId's in the onCheckedChanged() starts from seven, instead of one. Why does it not start from one in the new activity call? How to solve it? Here's my "FilterChoice" activity.

I have not yet figured out the behavior you describe, but I would point out that you can set the IDs of the RadioButtons you're creating dynamically. For example, in your "Categories" block:
for (int i = 0; i < SearchResults.cate.size(); i++) {
rb = new RadioButton(FilterChoice.this);
rb.setId(i + 1);
rb.setText(SearchResults.cate.get(i).key + " ("
+ SearchResults.cate.get(i).value + ")");
rg.addView(rb);
}
This will set IDs from 1 to SearchResults.cate.size(), which I believe is what you're going for.
