The list of spinner is too long and i need to minimize the list length

the list of the spinner is too long and i need to minimize it to 10 only

Then generate a sublist of the first 10 items, and use that.

coud you tell me how?

You can use two spinners for example.

Example :

In first spinner user select Country name.
And, the second spinner populates with the states name depending upon the selection of first spinner.

A searchable list could be an alternative solution, may be?
