In order to add entries to the spinner you need to define an Adapter i give you an example:
spinner = (Spinner) findViewById(R.id.spinner2);
List<String> list = new ArrayList<String>();
list.add("list 1");
list.add("list 2");
list.add("list 3");
ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this,
android.R.spinner_item, list);
spinner.setAdapter(dataAdapter);
Spinner likes ListView, need an adapter for rendering data. Adapter, in simple term, is a collection of items. (As you see ListView always contains list of item and also Spinner). Nevertheless, Adapter of spinner often a list of string. (because spinner just represents user choice)
In your example, You can simply create ArrayAdapter and assign again to Spinner.
private void setTextForSpinner(Spinner spinner) {
String[] items = {"Stack", "Over", "Flow"};
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, items);
spinner.setAdapter(adapter);
}
If apply above code to your example, you can change again to:
private void setTextForSpinner(Spinner spinner, String NewName) {
String[] items = {NewName};
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, items);
spinner.setAdapter(adapter);
}
Hope this help :)

I'm trying to populate value of the next spinner from the previous spinner. In this case, what I did yet is generating all values inside the spinner means, no matter which value I select in the previous spinner it is always showing all values in the next spinner. I'm using five spinners that needs to populate values according to the previous one. Here I'm using a library for the spinner. The library is as follows.
'com.toptoche.searchablespinner:searchablespinnerlibrary:1.3.1'
Here I'm sharing my whole code/class for your consideration. There is no error and I get all values in respective spinner but I want to get values according to the previous one. here is my code.

So how can I get rid of this problem? I need help.
You are declaring all adapter at once in onCreate().
Instead declare just first adapter with values in onCreate() and declare other adapters with empty values.
#Override
protected void onCreate(Bundle savedInstanceState) {
--------;
// Set spninner adapter
regionAdapter = new ArrayAdapter<>(this, android.R.layout.simple_spinner_item, Region);
districtAdapter = new ArrayAdapter<>(this, android.R.layout.simple_spinner_item, new String[]());
upzAdapter = new ArrayAdapter<>(this, android.R.layout.simple_spinner_item, new String[]());
unionAdapter = new ArrayAdapter<>(this, android.R.layout.simple_spinner_item, new String[]());
villageAdapter = new ArrayAdapter<>(this, android.R.layout.simple_spinner_item, new String[]());
------
spinner_region.setOnItemSelectedListener(this);
}
Now on itemSelectedListener, filter the desired values if needed and add the values to the next required adapter and notify the values along with adding listener to next spinner(adding listener is up to you, how you want to handle the things)
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
if (parent.getId() == R.id.region) {
positions = spinner_region.getSelectedItemPosition();
String[] filteredDistrict = District.filter(Region[position]) // District.filter is not any predefined function, assuming some filter needed for selected Districts
districtAdapter.addValues(filteredDistrict);
districtAdapter.notifyDataSetChanged()
spinner_district.setOnItemSelectedListener(this);
}
}
Other than that filtering logic depends on your usecase.
my problem is the following. I have 2 Spinners in one activity. I want that both spinner items should be saved in the DB. But there is a slight difference between both spinners:
Spinner 1: Is populated by data from other db-table - when it is the only spinner in the mentioned activity, it works.
Spinner 2: Has default values. I am not sure if added it correctly to my activity. Anyway, after i added it to my saving the data is not working anymore.
Please help me what am I doing wrong??

EDIT:
I tried to run the app by setting a few breakpoints.
When trying to run this line selectedTransport = (String) ChooseTransport.getSelectedItem(); the debugger posts Cannot find local variable 'ChooseTransport'
I solved the problem:
I implemented an own method for ChooseTransport- Spinner and now it works. I also figured out that the order how I add the data to the DB was not right. I changed this too.
See here my method for my second spinner:
private void loadTransportSpinnerData(){
ArrayAdapter<CharSequence> spinnerArrayAdapter = ArrayAdapter.createFromResource(this, R.array.transport, android.R.layout.simple_spinner_dropdown_item);
spinnerArrayAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
ChooseTransport.setPrompt("Transport auswählen");
ChooseTransport.setAdapter(spinnerArrayAdapter);
ChooseTransport.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
selectedTransport = (String) ChooseTransport.getSelectedItem();
}
#Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
});
}

I am creating spinners dynamically when i click add button.but i dont know how to get the values from created dynamic spinners.I need to get values how many shirt selected, saree selected and jeans selected when i click a submit button
this is my code
buttonAdd = (Button)findViewById(R.id.add);
container = (LinearLayout)findViewById(R.id.container);
final List<String> dressArray = new ArrayList<String>();
dressArray.add("Select Dress");
dressArray.add("Shirt");
dressArray.add("Saree");
dressArray.add("Jeans");
ArrayAdapter<String> adapter = new ArrayAdapter<String>(
this, android.R.layout.simple_spinner_item, dressArray);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
Spinner dress = (Spinner) findViewById(R.id.dress);
dress.setAdapter(adapter);
final List<String> dresscountArray = new ArrayList<String>();
dresscountArray.add("Count");
dresscountArray.add("1");
dresscountArray.add("2");
dresscountArray.add("3");
ArrayAdapter<String> adapter1 = new ArrayAdapter<String>(
this, android.R.layout.simple_spinner_item, dresscountArray);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
Spinner dresscount = (Spinner) findViewById(R.id.dresscount);
dresscount.setAdapter(adapter1);
buttonAdd.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View arg0) {
LayoutInflater layoutInflater =
(LayoutInflater) getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
final View addView = layoutInflater.inflate(R.layout.row, null);
Spinner dresscount = (Spinner)addView.findViewById(R.id.dresscount);
Spinner dress = (Spinner)addView.findViewById(R.id.dress);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(
PickupOrder.this, android.R.layout.simple_spinner_item, dressArray);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
dress.setAdapter(adapter);
ArrayAdapter<String> adapter1 = new ArrayAdapter<String>(
PickupOrder.this, android.R.layout.simple_spinner_item, dresscountArray);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
dresscount.setAdapter(adapter1);
Button buttonRemove = (Button)addView.findViewById(R.id.remove);
buttonRemove.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View v) {
((LinearLayout)addView.getParent()).removeView(addView);
}});
container.addView(addView);
}});
Firstly define globally
String value1;
int value_position1;
And then call these methods inside onCreate after setting value in each Spinner
spinner1.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent,
View view, int position, long id) {
value_position1 = position;
value1 = parent.getSelectedItem().toString()
.trim();
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
And when you call your submit button, use values of each String.
showallPrompt = "";
int Count = new_container.getChildCount();
try {
for (int cc = 0; cc < Count; cc++) {
View child = new_container.getChildAt(cc);
Spinner value = (Spinner)(child.findViewById(R.id.sp_dynamic));
String spin_value = value.getSelectedItem().toString();
showallPrompt += spin_value;
}
} catch (Exception e) {
}
Toast.makeText(MainActivity.this,
showallPrompt,
Toast.LENGTH_LONG).show();
}
}
Do like this on your button click...

adapterrep.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
Comrep.setAdapter(adapterrep);
Comrep.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
Comrep.setSelection(position);
}
#Override

});
thanks in advance..
You're not actually accumulating any values in your array. You're making a new array each time you go through the loop.
ArrayList<String> values = new ArrayList<String>();
while (cursor.moveToNext()) {
String rep = cursor.getString(cursor.getColumnIndex(User.KEY_username));
values.add(rep);
}
cursor.close();
ArrayAdapter<CharSequence> adapterrep = new ArrayAdapter<CharSequence>(this, R.layout.spinner_item, values.toArray(new String[values.size]));
You should look at CursorAdapter. You could make an adapter directly from your cursor so you don't need to code the loop.
