Question

我不敢确定标题是ok的,而是试图加以更好的解释。

I want to show a grid in my layout. To do that, i m using a custom ArrayAdapter. I don t how to set the onClickListener to each item...

布局包括一个标签、一个名称和一个网格。

这是我的活动:

public class Sala extends Activity{
GridView gridView;
TextView label_name;

ArrayList<String> lista_opciones = new ArrayList<String>();  

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.layout_sala);
    //Refresh the name in the label
    Bundle bundle=getIntent().getExtras();
    String name= bundle.getString("name");
    label_name= (TextView) findViewById(R.id.label_name);
    label_name.setText(name);

    //Loading array
    lista_op.add("Op 1");  
    lista_op.add("Op 2");  
    lista_op.add("Op 3");  
    lista_op.add("Op 4"); 

    //AdaptadorOpciones
    ArrayAdapterOpciones mAdapter = new ArrayAdapterOptions(this,lista_op);  

    //Set the customAdapter to the grid
    gridView = (GridView) findViewById(R.id.grid); 
    gridView.setAdapter(mAdapter);

你可以在你的调子中增加听众。抵达观点执行:

    @Override       
    public View getView(int position, View convertView, ViewGroup parent) {
        ImageView button = (ImageView) convertView;
        if (button == null) {
            button = new ImageButton(); // or whatever
            button.setOnClickListener(this);
        }
        button.setId(ids_present.get(position));
        return button;
    }
