如何在具有多个ListView的Activity中设置ScrollView？

这是我的实际活动时间： enter image description here 如何在具有多个ListView的Activity中设置ScrollView？

在这个活动我设置的所有ListView控件（S）和动态编程。正如你所看到的，这个问题我已经是第一的ListView需要的地方，她需要和第二的ListView尽量保持通过内部加入一个滚动条显示..

我只是想知道我怎么能说编程让所有的ListView（s）在她需要的整个地方取，并且只需要添加一个ScrollBar到所有的活动中（例如滚动菜单）？

这里是我的活动，我的适配器：

public class SousBoissonsActivity extends Activity { 
    private String nom_categorie; 
    private ArrayList<String> arraySousCategoriesName; 
    private ArrayList<ArrayList<Drink>> arraySousCategories; 
    private ArrayList<MyAdapter> myAdapters; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_sousboissons_list_item); 

     nom_categorie = getIntent().getStringExtra("nom_categorie"); 
     setTitle(nom_categorie); 
     DrinksContainer.setSousCategoriesNameArray(nom_categorie); 
     DrinksContainer.setSousCategoriesArray(nom_categorie); 

     arraySousCategories = DrinksContainer.sousCategoriesArray; 
     myAdapters = new ArrayList<MyAdapter>(); 

     new DoDirtyJobAsyncTask().execute(); 
    } 

    @Override 
    protected void onResume() { 
     super.onResume(); 
    } 

    @Override 
    protected void onDestroy() { 
     super.onDestroy(); 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     return super.onOptionsItemSelected(item); 
    } 

    private class DoDirtyJobAsyncTask extends AsyncTask<Void, MyAdapter, Void> { 
     @Override 
     protected Void doInBackground(Void... params) { 
      for (ArrayList<Drink> arrayElement : arraySousCategories) { 
       MyAdapter myAdapter = new MyAdapter(getApplicationContext(), 
         arrayElement); 
       myAdapters.add(myAdapter); 
       publishProgress(myAdapter); 
      } 
      return null; 
     }

       sousCategorieTitle.setBackgroundColor(getResources().getColor(

为什么不尝试用水平滑块并排创建它们？这将会更加方便用户使用。（像这样：http://www.e-nature.ch/tech/simple-tutorial-for-a-smooth-horizontal-view-slider-with-android/） – 2013-03-28 11:03:50

水平滑块很酷，但我们只能添加类到主要的片段..在这里我添加ListViews，而不是使用多个类.. – eento 2013-03-28 11:23:50

你知道如何使用水平滑块动态元素？ – eento 2013-03-28 11:35:36

你不应该巢ListViews一个ScrollView内，Android将不知道哪个滚动。也许...你将能够编程设置每个ListView的固定高度，然后它就可以工作。

我推荐的是使用单个ListView，并在该列表中将所有数据分组，或使用ExpandableListView。

是的，你是正确的ScrollView .. ExpandableListView是不是我想要实现的设计，所以我必须解决它的方式是使1只ListView或可以使用水平滑块（@Nuno Goncalves）.. – eento 2013-03-28 11:14:17

如果问题是UI设计请记住，加载时可扩展ExpandableListView。当您设置适配器并将视图设置为展开状态时。界面就像有一个ListView，你可以为组（Eaux，Petillants，...）设置一个样式，为孩子设置另一个样式。 – AlexBcn 2013-03-28 11:50:38

好吧我会尝试实现ExpandableListView！我认为可能会像我想但从来没有使用ExpandableListView .. – eento 2013-03-28 12:01:39

一般而言，在ScrollView内部添加ListView的做法很糟糕。如果你把你的ListView or any scrollable View inside the ScrollView it won't work properly because when you touch the screen ,main focus of your touch is on parent view( ScrollView ) not the child View ( ListView`）。

不过，如果你想实现它，然后下面是你可以尝试的方式，这是添加FooterView或HeaderView在ListView。

添加意见认为应高于ListView作为标题：

addHeaderView(View v);

和下面的页脚：

addFooterView(View v);

将所有的东西应该是什么上面ListView到ListViewHeader和相同页脚添加到下面。

LayoutInflater inflater = LayoutInflater.from(this); 
mTop = inflater.inflate(R.layout.view_top, null); 
mBottom = inflater.inflate(R.layout.view_bottom, null); 

list.addHeaderView(mTop); 
list.addFooterView(mBottom); 
// add header and footer before setting adapter 
list.setAdapter(mAdapter);

结果你会得到一个可滚动的视图。
