Mutiple listviews with one only scrolls

Question

I need to put several listviews inner a LinearLayout. The Listviews should be wrap content to adapt the listview to their items. I need have one only scroll with which I can scroll all the listviews. I know that i can't use a scrollview because the listviews have their own scroll (but i don't need the scrolls of the listviews because i have them in wrap-content). I thought maybe puting the listviews inside the LinearLayout I will hadn't problems with the scrollview, but it didn't work, the LinearLayout was fixed to the screen, the scrollview didn't appear and the listviews ended scrollable. Without the scrollview if i have the list in wrap-content, their shown properly but i haven't any scroll and i can't see the lisviews below the screen. Really i have had this bug for one month and i haven't found any solution, i am desperate :(

My code:

XML

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/detail_info_on_top" 
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" 
    android:background="#FF003150"
    android:orientation="vertical">
<!--<ScrollView android:layout_width="fill_parent"-->
<!--    android:layout_height="fill_parent"-->
<!--    android:fillViewport="true">-->
    <LinearLayout 
            android:id="@+id/layout"
            android:scrollbars="vertical"
            android:scrollbarAlwaysDrawVerticalTrack="true" 
            android:orientation="vertical"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content">
    </LinearLayout>
<!--</ScrollView>-->

            layout.addView(ll); 

        }
   }

Why are you using two ListViews, a GridView would probably suit you better. — Pentium10, Aug 13 '10 at 14:12
I am using more of two listviews, i have multiple listviews depending of the Data Base and then i put them inside a linearLayout. How i could use a gridView for this? i need a list not a grid. Can you give me some example of how i can resolve my problem with a gridview? Thanks for response — Luciano, Aug 13 '10 at 14:36

That is not possible, sorry.

Don't do that. Create one ListView. Combine your database results into a single adapter and put that adapter in the ListView. Perhaps my MergeAdapter can help.

I was trying to achieve your goal but failed and i don't have a lot of time to waste but here is my attempt code:

package your.packag;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AbsListView;
import android.widget.AbsListView.OnScrollListener;
import android.widget.BaseAdapter;
import android.widget.ListView;
import android.widget.TextView;

public class TestScrollingActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        final ListView lv1 = (ListView) findViewById(R.id.listView1);
        final ListView lv2 = (ListView) findViewById(R.id.listView2);
        final ListView lv3 = (ListView) findViewById(R.id.listView3);
        final ListView lv4 = (ListView) findViewById(R.id.listView4);
        final ListView lv5 = (ListView) findViewById(R.id.listView5);
        BaseAdapter ba = new BaseAdapter() {

            @Override
            public View getView(int position, View convertView, ViewGroup parent) {
                TextView tv = new TextView(parent.getContext());
                tv.setText(String.valueOf(position));
                return tv;
            }

            @Override
            public long getItemId(int position) {
                // TODO Auto-generated method stub
                return position;
            }

            @Override

            @Override
            public int getCount() {
                // TODO Auto-generated method stub
                return 100;

        };
        lv1.setAdapter(ba);
        lv2.setAdapter(ba);
        lv3.setAdapter(ba);
        lv4.setAdapter(ba);
        lv5.setAdapter(ba);
        OnScrollListener onScrollListener = new OnScrollListener() {

            @Override
            public void onScrollStateChanged(AbsListView view, int scrollState) {
                if (scrollState == SCROLL_STATE_IDLE) {
                    int top = view.getHeight()/view.getAdapter().getCount()*view.getFirstVisiblePosition();
                    if (lv1 != view) {
                        lv1.scrollTo(0, top);
                    }
                    if (lv2 != view) {

                    }
                }
            }

            @Override
            public void onScroll(AbsListView view, int firstVisibleItem,
                    int visibleItemCount, int totalItemCount) {

}

Scrolling fails in a strange way be sure to try it and let me know if you fixed it.

P.S. this comes very close to making it work.

Another way to go at it is to make a custom layour for each row and put your stuff in there from all the LVs u wanna make, it will scroll together because it's 1 LV after all — Shereef Marzouk, Feb 28 '12 at 12:59
