Android Spinner 以编程方式加载

Question

In my android APP I have 3 spinners. When I select an item from Spinner 1 according to that selection Spinner 2 data will be loaded. And When I select an item from Spinner 2 according to that selection Spinner 3 data will be loaded. That process is working. But I want to reloaded the same selections when I come back to the same activity from another activity. I have the selected values on session. I just want to reload the spinners and select the previous values so user don't have to go through selection process again. How I can achieve this.

With this command you can update it: adapter.notifyDataSetChanged();
