spinner=(Spinner)findViewById(R.id.spinner);

6.define a string Array for country data-

String[] country;

7.now get resource of country from xml file-

country =getResources().getStringArray(R.array.countries_array);

8.now create a adapter-

ArrayAdapter<String> adapter = new

 ArrayAdapter<String>(this,android.R.layout.simple_spinner_item,country);

9.after that set value to spinner of adapter-

spinner.setAdapter(adapter);

final  MainActivity.java look like below-

	package com.internationalschooling.myapplication;
	import android.graphics.Color;
	import android.support.v7.app.AppCompatActivity;
	import android.os.Bundle;
	import android.widget.ArrayAdapter;
	import android.widget.Spinner;
	public class MainActivity extends AppCompatActivity {
	private Spinner spinner;
	String[] country;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
	super.onCreate(savedInstanceState);
	setContentView(R.layout.activity_main);
	spinner=(Spinner)findViewById(R.id.spinner);
	country =getResources().getStringArray(R.array.countries_array);
	ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item,country);
