如何在具有多重的ListView（S）活动设置滚动型？如何在、ListView

2023-09-12 05:58:13 作者：搜狗丶搜出一条狗

这是我的实际活动：

在这个活动我设置的所有的ListView（S）和动态编程。正如你所看到的，这个问题我已经是第1 ListView控件需要她需要的地方第二ListView中尽量保持显示通过在内部增加一个滚动条。

我只是想知道我怎么能说编程，让所有的ListView（S）取整座她需要，只是一个滚动条添加到所有的活动（可以滚动菜单为例）？

Android开发ListView用的是BaseAdapter怎么在关闭有ListView的这个Activity时获得每个Item中的控件值

下面是我的活动，我的适配器：

解决方案

您不能嵌套列表视图在滚动型 Android将不知道哪个滚动。也许......你就可以编程设定固定高度每的ListView ，然后它会工作。

我会建议要么使用单一的ListView ，并且组在该列表中的所有数据，或使用的 ExpandableListView 。

This is my actual Activity :

In this Activity I set All the ListView(s) dynamically and programmatically. As you can see, the problem I have is The 1st ListView takes the place she needs and the second ListView try to keep showing by internally adding a scroll bar..

I just wanted to know how can I say programmatically to let all the ListView(s) take the entire place she needs and just add a ScrollBar to all the activity (To Scroll the Menu for example)?

Here is my Activity and my Adapter :

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);

You should not nest ListViews inside a ScrollView, Android won't know which to scroll. Maybe... you will be able to set programatically the fixed height for each ListView, and then it will work.

What I would recommend is either to use a single ListView, and group in that list all the data, or to use an ExpandableListView.
