问题
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

MyAdapter myAdapter = new MyAdapter(getApplicationContext(),
arrayElement);
myAdapters.add(myAdapter);
publishProgress(myAdapter);
}
return null;

回答1:
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.
回答2:
Generally its a bad practice to add the ListView inside ScrollView. If you put your ListView or any scrollable View inside theScrollViewit 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`).
Still if you want to implement it then below is the way you can try out, which is to add the FooterView or HeaderView in your ListView.
Add views that should be above ListView as a header:
addHeaderView(View v);
and that below as a footer:
addFooterView(View v);
Put everything what should be above ListView to Header of ListView and the same with footer to add below.
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);
In result you'll get one scrollable view.
