如何将图标添加到数组列表中

Question

我有两个主要的主要数据和数据。

在数据中我有3个属性：

nombre;---> the name of the team
 imagen;--->logo of the team
 web;--->and team webpage

Datos类：

public class Datos {
    private String nombre, website;
    private int imagen;

    public Datos(String nombre, String website, int imagen) {
        this.nombre = nombre;
        this.website = website;
        this.imagen = imagen;
    }

    public String getNombre() {
        return nombre;
    }

    public void setNombre(String nombre) {
        this.nombre = nombre;
    }

    public String getWebsite() {
        return website;
    }

    public void setWebsite(String website) {
        this.website = website;
    }

    public int getImagen() {
        return imagen;
    }

    public void setImagen(int imagen) {
        this.imagen = imagen;
    }


}

主：

@Override
    protected void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        setContentView(R.layout.mainlayout);
        spinner = (Spinner)findViewById(R.id.spinner);
        cargaspinner();
    }

    public void cargaspinner(){
        ArrayList<datos> datosArrayList = new ArrayList<datos>();
        datosArrayList.add(new datos("Barcelona", barcelona.com, ??));
        ArrayAdapter<datos> adapter = new ArrayAdapter(this, R.layout.support_simple_spinner_dropdown_item, datosArrayList);
        spinner.asetAdapter(adapter);
    }

main datos

Answer 1

图标/绘图在android中基本上是int所以你可以声明图像/图标列表如下：

List<Integer> icons = new ArrayList<>();

icons.add(R.drawable.icon1);
icons.add(R.drawable.icon2);

所以你必须修改这样的方法：

public void cargaspinner(){
        ArrayList<Datos> datosArrayList = new ArrayList<Datos>();
        datosArrayList.add(new Datos("Barcelona", "http://www.barcelona.com", R.drawable.image));
        ArrayAdapter<Datos> adapter = new ArrayAdapter(this, R.layout.support_simple_spinner_dropdown_item, datosArrayList);
        spinner.asetAdapter(adapter);
    }
