从一个 ListView 移动到另一个 ListView

Question

我是 android 开发和创建列表项的新手，这里是我的两个 classes 代码。我正在尝试从菜单移动到另一个也实现了列表视图的 activity(Prepaid)。问题是它不能转移到预付 activity。我的 Header 也从菜单 class 中丢失了，如何在菜单 class 上显示 header 栏？

菜单 Class

public class Menu extends ListActivity {

String classes[] = {"Prepaid" , "Postpaid"};

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setListAdapter(new ArrayAdapter<String>(Menu.this, android.R.layout.simple_list_item_1, classes));
}

@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
    super.onListItemClick(l, v, position, id);
    String whichItemClicked = classes[position];

    try
    {
        Class ourClass = Class.forName("adnan.com.ufone" + whichItemClicked);
        Intent ourIntent = new Intent(Menu.this, ourClass);
        startActivity(ourIntent);
    }
    catch (ClassNotFoundException e)
    {
        e.printStackTrace();
    }

}

}

预付 Class

public class Prepaid extends ListActivity {

String prepaidServices[] = {"UAdbanced" , "Packages", "Internet"};

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setListAdapter(new ArrayAdapter<String>(Prepaid.this , android.R.layout.simple_list_item_1, prepaidServices ));

}

@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
    super.onListItemClick(l, v, position, id);
    String ItemClicket = prepaidServices[position];

    try{
        Class myClass = Class.forName("adnan.com.ufone" + ItemClicket);
        Intent myIntent = new Intent(Prepaid.this, myClass);
        startActivity(myIntent);

    }
    catch (ClassNotFoundException e){
        e.printStackTrace();
    }
}

}

MD 已经提供了将一个列表 activity 移动到第二个列表 activity 的答案。只需要添加点(.) like

Class ourClass = Class.forName("adnan.com.ufone." + whichItemClicked);

对于 header 问题，请遵循 This Tutorial 这可能对您有所帮助。本教程修复了所有活动的 header 和页脚。
