Display available currencies java.util.Currency

This example list available currencies java.util.Currency. Please notice that the methods getAvailableCurrencies() and getDisplayName() used in this example introduced in API Level 19. So android:minSdkVersion in AndroidManifest.xml have to be set ="19".


package com.example.androidcurrency;

import java.util.ArrayList;
import java.util.Currency;
import java.util.List;
import java.util.Set;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;

public class MainActivity extends Activity {

 ListView listCurrency;
 Set<Currency> availableCurrenciesSet;
 List<Currency> availableCurrenciesList;
 ArrayAdapter<Currency> adapter;
 
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  listCurrency = (ListView)findViewById(R.id.currencylist);
  
  //available from API Level 19
  availableCurrenciesSet = 
   Currency.getAvailableCurrencies();
  
  availableCurrenciesList = new ArrayList<Currency>(availableCurrenciesSet);
  adapter = new ArrayAdapter<Currency>(
    this, 
    android.R.layout.simple_list_item_1, 
    availableCurrenciesList);
  listCurrency.setAdapter(adapter);
  
  listCurrency.setOnItemClickListener(new OnItemClickListener(){

   @Override
   public void onItemClick(AdapterView<?> parent, View view,
     int position, long id) {
    Currency currency = (Currency) parent.getItemAtPosition(position);
    String currencyCode = currency.getCurrencyCode();
    String displayName = currency.getDisplayName();
    String symbol = currency.getSymbol();
    
    Toast.makeText(MainActivity.this, 
     displayName + "\n" +
     currencyCode + "\n" +
     symbol, 
     Toast.LENGTH_LONG).show();
   }});
 }


}
