I have the following code, which adds spinners based on a loop (my loop is different in my real version, but simplified here since the outcome is the same).
for(int i = 0; i < 2; i++
Spinner spinner = new Spinner(this);
spinner.setId(result.getInt(0));
Cursor result2 = databaseHelper.retrieveData(DatabaseHelper.LISTTABLE,"`Select list`",result.getString(8),null);
listDynamic.clear();
listDynamic.add("");
for(int j = 0; j < result2.getCount(); j++)
result2.moveToNext();
listDynamic.add(result2.getString(7));
ArrayAdapter arrayAdapter = new ArrayAdapter<>(this, android.R.layout.simple_spinner_item, listDynamic);
spinner.setAdapter(arrayAdapter);
result2.close();
listSpinners.add(spinner);
rlParent.addView(spinner);
So what works: The spinners work as expected.
The code produces this result: The spinners will only use the last iteration of listDynamic and arrayAdapter. Basically resulting in the following:
Spinner 1
- Q
- W
- E
Spinner 2
- Q
- W
- E
The result that should happen (in my mind) is that there should be two different lists shown in each spinner. Similar to this:
Spinner 1
- A
- B
- C
Spinner 2
- Q
- W
- E
I suspect there is a thing about ArrayAdapters that I am missing?

You are using same list for both spinners that why items are same .
SOlutions 1: declare listDynamic locally .
listDynamic.clear(); -> List listDynamic=new Arraylist();
Solution 2: use different list object for different spinners listDynamic1,listDynamic2 ...
Hope this will help
