How to programatically set entries of spinner in android?

I have made various string-arrays in the string.xml file and I have to set different arrays as entries for the spinner according to certain condition in Java. Is it possible or is database the only way to do so. Thanks in advance.

You need to use an adapter and populate with tha array in xml file.

Specify the name of your array in xml at createFromResource method (second parameter).

ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.my_array, android.R.layout.simple_spinner_item);   
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
mySpinner.setAdapter(adapter);

You have to extract your data from file:

String[] testArray = getResources().getStringArray(R.array.testArray);

Then, you have to inflate in the spinner:

ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(
            this, android.R.layout.simple_spinner_item, testArray );
mySpinner.setAdapter(spinnerArrayAdapter);

You can start with using ArrayAdapter, it is a simple class to populate spinner items programmatically. 

String data[];
//... do your stuff to get populate this array
ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(
            this, android.R.layout.simple_spinner_item, data);
mySpinner.setAdapter(spinnerArrayAdapter);

You can also modify the view of dropdown items and customize them further by overriding this class.
