I have Spinner in my app and set String[] programmatic.
speciality = (Spinner) findViewById(R.id.general_specality_s);
specialityadapter = new ArrayAdapter<String>(this,
android.R.layout.simple_spinner_item, speciality_list);
speciality.setAdapter(specialityadapter);
and get selected string like this speciality.getSelectedItem().toString(); and store in sqlite. Now I want to get that value from sqlite and need to set in Spinner1.
String SpinnerText=c.getString(c.getColumnIndex("speciality"));
How to set this string to speciality / Spinner ? Thanks in advance.
Fetch your data into an array and use an array adapter
String[] spinnerArray = your data goes here;
Spinner spinner = (Spinner)findViewById(R.id.yourspinnerid);
ArrayAdapter<String> spinnerAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, spinnerArray);
spinnerAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(spinnerAdapter);

I am getting error for the following code which implements Spinner with multi-dimensional array.
Spinner sp1 = (Spinner) findViewById(R.id.spinner1);
String dept[][] ={{"cs","101"},{"me","102"}};
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_dropdown_item_1line, dept);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
sp1.setAdapter(adapter);
How can i populate a Spinner from String array , I know i can do that from array.xml like this code :
ArrayAdapter<CharSequence> gameKindArray = ArrayAdapter.createFromResource(view.getContext(),R.array.game_kind, android.R.layout.simple_spinner_item);
gameKindArray.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
gameKind.setAdapter(gameKindArray);
but when i have
String[] test=new String[]{"test1","test2"};
how i can change String[] to ArrayAdapter ?!
Use ArrayAdapter this way
your string array
String[] test=new String[]{"test1","test2"};
your ArrayAdapter
ArrayAdapter<String> gameKindArray= new ArrayAdapter<String>(MyActivityClass.this,android.R.layout.simple_spinner_item, test);
gameKindArray.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
gameKind.setAdapter(gameKindArray);
Try the below
ArrayAdapter<String> gameKindArray = new ArrayAdapter<String>(this,
android.R.layout.simple_spinner_item, test);
gameKind.setAdapter(adapter);
For more info check the docs.

you dont need to convert in any form just use your string array like below:
ArrayAdapter<String> gameKindArray= new ArrayAdapter<String>(MyActivityClass.this,android.R.layout.simple_spinner_item, test);
gameKindArray.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
gameKind.setAdapter(gameKindArray);
you can get easily into spinner.
I have two spinners and two arrays. However, one spinner receives both arrays while the other receives no values from either of the two arrays. Note: I do not want to use radio buttons as the data is shortened for review.
final ArrayList<String> serialnums = new ArrayList<String>();
serialnums.add("576798");
serialnums.add("495874");
serialnums.add("345667");
serialnums.add("956345");
final ArrayList<String> carrys = new ArrayList<String>();
serialnums.add("R");
serialnums.add("L");
serialnums.add("F");
serialnums.add("B");
s1 = (Spinner) findViewById(R.id.spinnerSerial);
spinnerCarry = (Spinner) findViewById(R.id.spinnerCarry);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, serialnums );
ArrayAdapter<String> adapterCarrys = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, carrys );
s1.setAdapter(adapter);
spinnerCarry.setAdapter(adapterCarrys);
Note 2: Spinner s1 gets all the data
One spinner has all the data because you are assigning all the data to it. Change this:
final ArrayList<String> carrys = new ArrayList<String>();
serialnums.add("R");
serialnums.add("L");
serialnums.add("F");
serialnums.add("B");
to this:
final ArrayList<String> carrys = new ArrayList<String>();
carrys.add("R");
carrys.add("L");
carrys.add("F");
carrys.add("B");
You are adding "R" "L" "F" "B" to serialnums add it to carrys
I have within a TabActivity a Spinner that will be generated dynamically. Just to test, I did so manually:
Spinner sp_departure = (Spinner) findViewById(R.id.spinner_departure);
// This array will be generated through a database
String[] array_spinner = new String[2];
array_spinner[0] = "Departure 1";
array_spinner[1] = "Departure 2";
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, array_spinner);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
sp_departure.setAdapter(adapter);
When I run the app looks ok since option selected is "Departure 1" but when I click to open the options I get some errors and the application is closed.
Any idea what could be wrong?
Thanks in advance.

Yes you might have set setContetView(R.layout.yourxml)...,
Change it to :
View viewToLoad = LayoutInflater.from(this.getParent()).inflate(R.layout.yourxm, null);
this.setContentView(viewToLoad);
and use
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getParent(), android.R.layout.simple_spinner_item, array_spinner);
Try, it may helps you
I have spinner in my application .The spinner have drop down list.I want to take the value of the dropdown list from the database .how can i do this ?
here is my code for spinner with dropdownlist:
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, selectdefault);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
You must create an array to specify which fields you want to display.
You could try this.
DatabaseProfileHelper dbhelper = new DatabaseProfileHelper(context);
// create an array to specify which fields we want to display
String[] from = new String[] { DatabaseProfileHelper.colNama };
int[] to = new int[] {R.id.txtProfileNama};
Cursor c = dbhelper.getAllProfiles();
dbhelper.UpdateProfile(null);
c.moveToFirst();
startManagingCursor(c);
// create simple cursor adapter
SimpleCursorAdapter ca=new SimpleCursorAdapter(context,R.layout.profile_spinner_row, c, from, to);
// get reference to our spinner
spinProfile.setAdapter(ca);
