Question

My code is very long so I will describe my problem. It’s about the size and position of a Spinner. My ListView has items, each item has a TextView and a Spinner. The data in Spinners is different. I only operate data of the first one when I click the Spinner. It will pop out. The data in the Spinner comes from a list of database. When I edit the data (delete, move, add) in fact, I edit the data from an array. The question is when I pop out the spinner it will fill the whole screen, show at the centre of screen, the area around it will be gray and if I click the gray area the Spinner will hide again but I need it keep out state so I can do something about its data and don’t affect the other area (the grey area). Would anyone help me please? Thank you very much.

If you are trying to detect when the Spinner is hidden then you should implement OnItemSelectedListener in your Activity.

public void onItemSelected(AdapterView<?> parent, View view, 
        int pos, long id) {
    // An item was selected. Handle your data here
}

public void onNothingSelected(AdapterView<?> parent) {
    // No item was selected
}
