Hello,
I am trying to get the selected item of my spinner that is populated
and I am already seeing the values. when I try to use
(String) s.getSelectedItem(); to get the selected item, I am receiving
a handler exception on Logcat.
The spinner throwing the error is a 2nd spinner resulting from the 1st
spinner's selected item (that works perfectly). In other words, user
selects from spinner one and upon selection, populates spinner 2
(until here everything is fine). When trying to get the value of the
selected row in spinner2 , I am receiving the error.
here's the main parts of my code:
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);
// The drop down list for the list of universities
final Spinner s = (Spinner) findViewById(R.id.spinner);
ArrayAdapter adapter = ArrayAdapter.createFromResource(
this, R.array.universities,
android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource
(android.R.layout.simple_spinner_dropdown_item);
s.setAdapter(adapter);
// Initialization of the 2nd spinner
String[] array = {"this", "is", "driving", "me", "crazy"};
final Spinner s2 = (Spinner) findViewById(R.id.spinner2);
ArrayAdapter<String> cadapter = new ArrayAdapter(this,
android.R.layout.simple_spinner_item, array);
cadapter.setDropDownViewResource
(android.R.layout.simple_spinner_dropdown_item);
s2.setAdapter(cadapter);
// When user selects a university
s.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> arg0, View
arg1,
int arg2, long arg3) {
//Get the selected university
String selectedItemString = (String)
s.getSelectedItem();
// System.out.println
("Uni: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"+selectedItemString);
if(selectedItemString .equals(""))
{
// In case of an error so it won't crash
nospinner();
}
else
{
// Find the table of the selected University
dynamically
finder(selectedItemString);
}
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
// When user selects a university
s2.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> arg0,
View arg1,
int arg2, long arg3) {
// String selected =
(String)s2.getSelectedItem(); <---- it
crashes here
// System.out.println
("Building: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"+selected);
}
@Override
public void onNothingSelected(AdapterView<?>
arg0) {
// TODO Auto-generated method stub
}
});
}
protected void finder(String selectedItemString) {
final Dbadapter db = new Dbadapter(this); // This creates an
instance of the database in this class
final Spinner s2 = (Spinner)findViewById(R.id.spinner2);
// Access Database
db.open();
// Fix selected item to match the db
selectedItemString = (selectedItemString).toLowerCase();
selectedItemString = selectedItemString.replaceAll(" ","");
// Call a function to return the rows of that university
final Cursor cur = db.getAllTitles(selectedItemString);
//cur.moveToFirst();
// Get Columns
String[] columns = new String[]{"building"};
SimpleCursorAdapter cadapter = new SimpleCursorAdapter(this,
android.R.layout.simple_spinner_item, cur,
columns, new int[] {android.R.id.text1});
// Spinner Layout and population
cadapter.setDropDownViewResource
(android.R.layout.simple_spinner_dropdown_item);
s2.setAdapter(cadapter);
db.close();
}
