将菜单链接在一起

Question

我真的很难将菜单链接在一起。我要创建的应用程序是一组菜单，这些菜单指向我计划在应用程序中打开的各种站点的 url 链接。我创建了一个包含 8 个选项的列表活动菜单，并且我有八个带有更多选项的类。我的问题是如何将菜单链接在一起。我问了这个问题，有人说我应该映射。代码如下：

public class MyList extends ListActivity {

private static final String Cp = null;
private static final String Pp = null;
private static final String L2 = null;
private static final String L1 = null;
/** Called when the activity is first created. */
public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    // Create an array of Strings, that will be put to our ListActivity
    String[] names = new String[] { "Pp", "Cp", "L1", "L2", "Bt", "Se", "As", "Travel"};
    // Create an ArrayAdapter, that will actually make the Strings above
    // appear in the ListView
    this.setListAdapter(new ArrayAdapter<String>(this,
            android.R.layout.simple_list_item_checked, names));
}
{Map<String, Runner> runners = new HashMap<String, Runner>();
runners.put("Pp", (Runner) new Pp());
runners.put("Cp", (Runner) new Cp());
runners.put("L1", (Runner) new L1());
runners.put("L2", (Runner) new L2());


public void onListItemClick(runners.get(getListView()).L2();
runners.get(getListView()).L1();
runners.get(getListView()).Pp();
runners.get(getListView()).Cp(); {

我设置了一个名为 runners 的类，并在每个选项中添加了下一个菜单，如下所示：

公共接口 Runner {

void L2();

void L1();

void Pp();

void Cp();
}

目前我在这一行遇到一个错误 public void onListItemClick(runners.get(getListView()).League2(); void 是变量 onListItemClick 的无效类型，我这样做是否正确，我是否遗漏了什么，我应该使用这种方法吗？？

Answer 1

也许只是格式化？

public void onListItemClick() { runners.get(getListView()).L2(); runners.get(getListView()).L1(); runners.get(getListView()).Pp(); runners.get(getListView()).Cp(); }
