package com.comboyz.TantaGo;

import android.app.ListActivity;
import android.os.Bundle;
import android.widget.ArrayAdapter; 

public class startMenu extends ListActivity{
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
              super.onCreate(savedInstanceState);
          setListAdapter(new ArrayAdapter <String>(this,R.layout.startmenu,category));
    }
    static final String [] category= new String []{
        "cinema","restuarnt","hotel","cafe","women shoping","men shoping"
    };
}

我希望当我单击“电影院”时创建一个新列表，其中包含电影院和电影院的所有名称。当我按餐厅时，它会列出不同的列表，其中包含餐厅的所有名称等

有很多不同的方法可以做到这一点，但我建议做一些改变。

首先，使用 ListView 元素，而不是执行 ListActivity，请查看这个示例。

然后我建议使用 ViewFlipper，您可以设置动画在不同的视图元素之间翻转，它们的工作原理是它们具有视图元素的层次结构，一次只能显示一个，所以您要做的是，例如，

<ViewFlipper
      .... >

    <ListView
         ... >

    <ListView
         ... >

    <ListView
         ... >

</ViewFlipper>

当您在主 Activity 中获取视图翻转器时，您将设置显示的视图，当您设置 0,1,2 时，它将在列表视图之间翻转，例如 0 可能是主屏幕，1 剧院，2 餐厅， ETC

There are many different ways to do this, however I recommend doing a few changes.

First off, use a ListView element, apposed to doing ListActivity, check out this example.

Then I would suggest playing around with ViewFlipper, you can set animations to flip between the different view elements, how they work is they have a hierarchy of view elements, which can only show one at a time, so what you would do is, for example,

<ViewFlipper
      .... >

    <ListView
         ... >

    <ListView
         ... >

    <ListView
         ... >

</ViewFlipper>

When you get the View Flipper in your main Activity, you will set the displayed view, and as you set 0,1,2 it will flip between the list views, for example 0 could be main screen, 1 theaters, 2 restaurants, etc
