horizontallistview充填数组图片

修改gallery控制，读取Devsmart horizontallistview控制，运行不起来。

有一个来自网络服务器的整型数组，动态充填原来的gallery控制，怎么充填horizontalllistview？

   private void llenagallery() {
    int i,Id;
    for ( i = 0; i<(Servicios.length()); i++) {

        String valor = Character.toString(Servicios.charAt(i));

        if (valor.equals("a")) {
            Id = this.getResources().getIdentifier("a", "drawable", this.getPackageName());
            imagenes.add(Id);
        }else if (valor.equals("b")) {
            Id = this.getResources().getIdentifier("b", "drawable", this.getPackageName());
            imagenes.add(Id);
        }else if (valor.equals("c")) {
            Id = this.getResources().getIdentifier("c", "drawable", this.getPackageName());
            imagenes.add(Id);   
        }else if (valor.equals("d")) {
            Id = this.getResources().getIdentifier("d", "drawable", this.getPackageName());
            imagenes.add(Id);
        }else if (valor.equals("e")) {
            Id = this.getResources().getIdentifier("e", "drawable", this.getPackageName());
            imagenes.add(Id);
        }else if (valor.equals("f")) {
            Id = this.getResources().getIdentifier("f", "drawable", this.getPackageName());
            imagenes.add(Id);
        }else if (valor.equals("g")) {
            Id = this.getResources().getIdentifier("g", "drawable", this.getPackageName());
            imagenes.add(Id);
        }else if (valor.equals("i")) {
            Id = this.getResources().getIdentifier("i", "drawable", this.getPackageName());
            imagenes.add(Id);
        }else if (valor.equals("j")) {
            Id = this.getResources().getIdentifier("j", "drawable", this.getPackageName());
            imagenes.add(Id);
        }else if (valor.equals("l")) {
            Id = this.getResources().getIdentifier("l", "drawable", this.getPackageName());
            imagenes.add(Id);
        }else if (valor.equals("m")) {
            Id = this.getResources().getIdentifier("m", "drawable", this.getPackageName());
            imagenes.add(Id);
        }else if (valor.equals("n")) {
            Id = this.getResources().getIdentifier("n", "drawable", this.getPackageName());
            imagenes.add(Id);
        }else if (valor.equals("o")) {
            Id = this.getResources().getIdentifier("o", "drawable", this.getPackageName());
            imagenes.add(Id);
        }else if (valor.equals("p")) {
            Id = this.getResources().getIdentifier("p", "drawable", this.getPackageName());
            imagenes.add(Id);
        }else if (valor.equals("r")) {
            Id = this.getResources().getIdentifier("r", "drawable", this.getPackageName());
            imagenes.add(Id);
        }else if (valor.equals("s")) {
            Id = this.getResources().getIdentifier("s", "drawable", this.getPackageName());
            imagenes.add(Id);
        }else if (valor.equals("t")) {
            Id = this.getResources().getIdentifier("t", "drawable", this.getPackageName());
            imagenes.add(Id);
        }else if (valor.equals("u")) {
            Id = this.getResources().getIdentifier("u", "drawable", this.getPackageName());
            imagenes.add(Id);
        }else if (valor.equals("v")) {
            Id = this.getResources().getIdentifier("v", "drawable", this.getPackageName());
            imagenes.add(Id);
        }else if (valor.equals("w")) {
            Id = this.getResources().getIdentifier("w", "drawable", this.getPackageName());
            imagenes.add(Id);
        }else if (valor.equals("y")) {
            Id = this.getResources().getIdentifier("y", "drawable", this.getPackageName());
            imagenes.add(Id);
        }else if (valor.equals("z")) {
            Id = this.getResources().getIdentifier("z", "drawable", this.getPackageName());
            imagenes.add(Id);   
        }else if (valor.equals("P")) {
            Id = this.getResources().getIdentifier("euro1", "drawable", this.getPackageName());
            imagenes.add(Id);
        }else if (valor.equals("h")) {
            Id = this.getResources().getIdentifier("euro2", "drawable", this.getPackageName());
            imagenes.add(Id);   
        }
    }                                 

    HorizontalListView hscroll = (HorizontalListView)findViewById(R.id.iconos);
hscroll.setAdapter(new ImageAdapter(this,imagenes));

调试程序时，什么也没显示。

要看Adapter怎么写的了
