将countries[ ]改为ArrayList<<Post>> android

Question

在我的应用程序中，我尝试使用setter和getter方法填充轮子适配器，如我的Post类中所示。

类Post {

   private String imageList;
   private String country_name;
   private String country_code;

  public void setImageList (    String imageList){
        this.imageList = imageList;
    }

  public String getImageList (){
        return imageList;
    }


 public void setCountryName (   String country_name){
        this.country_name = country_name;
    }

  public String getCountryName (){
        return country_name;
    }
...


}

我的wheelAdapter类如下所示：

public class SecondWheelAdapter extends AbstractWheelTextAdapter {

    ArrayList<convertor_pst> PostList = new ArrayList<convertor_pst>();

    public ImageLoader imageLoader; 

    // Countries names
    private String countries[] =
            new String[] {"EUR", "USD","EUR", "USD","EUR", "USD","EUR", "USD","EUR", "USD","EUR", "USD"};

    // Countries flags
    private int flags[] = new int[] {R.drawable.eur, R.drawable.usd,R.drawable.eur, R.drawable.usd,R.drawable.eur, R.drawable.usd,R.drawable.eur, R.drawable.usd,R.drawable.eur, R.drawable.usd,R.drawable.eur, R.drawable.usd};

    /**
     * Constructor
     */


    Convertor main;

    public SecondWheelAdapter(Context context) {
        super(context, R.layout.country_layout, NO_RESOURCE);
        setItemTextResource(R.id.country_name);
    }

    @Override
    public View getItem(int index, View cachedView, ViewGroup parent) {

        View view = super.getItem(index, cachedView, parent);
        ImageView img = (ImageView) view.findViewById(R.id.flag);
        img.setImageResource(flags[index]);

        return view;
    }

    @Override
    public int getItemsCount() {
        return countries.length;
    }


    @Override
    protected CharSequence getItemText(int index) {
        return countries[index];
    }

我正在尝试替换这个数组

// Countries names
        private String countries[] =
                new String[] {"EUR", "USD","EUR", "USD","EUR", "USD","EUR", "USD","EUR", "USD","EUR", "USD"};

请给我一个提示或教程来遵循。我从github得到了这个轮子适配器，它附带了一个库，但我遇到了困难。

优化的解决方案：

我建议您创建一个ArrayList，而不是管理不同的字符串数组或ArrayList，这样管理单个ArrayList会更容易。

我的意思是删除countries[]和flags[]并创建单一的ArrayList<Post>类型。
