The results appear shopname no matter what I choose the spinner, always defaults to the value of the first item in the dropdown list, you master over here, really do not understand this thing a spinner, seeking advice.<-! Main posts under Banner (D4) -><-! Posts under the main text (D5) ->

Code is a mess, but it should be OnItemSelectedListener () inside wrong, check it yourself, provided you an idea to check it,
d = (Spinner) findViewById (R.id. spinner1);
ArrayAdapteradapter = ArrayAdapter.createFromResource (this, R.array.roompath, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource (android.R.layout.simple_spinner_dropdown_item);
d.setAdapter (adapter);
d.setPrompt ("shop address");
d.setOnItemSelectedListener (new OnItemSelectedListener () {
@ Override
public void onItemSelected (AdapterView arg0, View arg1,
int arg2, long arg3) {
/ / TODO Auto-generated method stub
roompath = String.valueOf (arg2) ;/ / this is to get the value
}
Reply:
Then after you get the value refers to the choice of the first few, and then pay the appropriate value for arg2, Friendly reminder written on the outside event oh.
Reply:
My store is to read the code from the database, Friendly reminder written on the outside event oh. Weak weak ask, what is written on the outside event oh? Gets the value of the selected item is it? Thank you
Reply:
Indeed OnItemSelectedListener () wrong, mainly stores spinner wrote two OnItemSelectedListener (). Thank you, the users answer. Of all to you.
