[android-developers] Re: Memory Allocation

You could store in an XML array file and inflate it each time spinner
is visible.

Like this:

Spinner spinner = (Spinner) findViewById(R.id.spinner);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
this, R.array.planets_array, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);

See here for more information: http://developer.android.com/resources/tutorials/views/hello-spinner.html

Bye!
