list2 = (ListView) findViewById(R.id.listview2);
list.setAdapter(new ArrayAdapter<String>(MainActivity.this,android.R.layout.simple_list_item_1,name));
list2.setAdapter(new ArrayAdapter<String>(MainActivity.this,android.R.layout.simple_list_item_1,name2));
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
// TODO Auto-generated method stub
Toast.makeText(getBaseContext(), name [position],Toast.LENGTH_SHORT).show();
}
});
list2.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,

android:id="@+id/LinearLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="${relativePackage}.${activityClass}" >
<TextView
android:id="@+id/text_id1"
android:layout_width="wrap_content"

You can try this.
FOR xml TO DO THIS:
Put all layout data in one scroll view like:
<ScrollView
android:id="@+id/scrollViewId"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<ListView
android:id="@+id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content" /> // SAY YOUR FIRST LIST VIEW:
<ListView
android:id="@+id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content" /> // SAY YOUR SECONDLIST VIEW:
// Add your other views as per requirement....
</LinearLayout>
</ScrollView>
NOW IN JAVA CLASS NEXT THING ...
Just add this custom method to your code after configuring the adapter to view the list:
setListViewHeightBasedOnChildren(listview)
Example:
list = (ListView) findViewById(R.id.listview);
list.setAdapter(new ArrayAdapter<String>
(MainActivity.this,android.R.layout.simple_list_item_1,name));
setListViewHeightBasedOnChildren(list);
Do this to display the second list.
Here is the body of setListViewHeightBasedOnChildren METHOD
public static void setListViewHeightBasedOnChildren(ListView listView)
{
ListAdapter listAdapter = listView.getAdapter();
if (listAdapter == null)
return;
int desiredWidth = MeasureSpec.makeMeasureSpec(listView.getWidth(), MeasureSpec.UNSPECIFIED);
int totalHeight=0;
View view = null;
for (int i = 0; i < listAdapter.getCount(); i++)
{
view = listAdapter.getView(i, view, listView);
if (i == 0)
view.setLayoutParams(new ViewGroup.LayoutParams(desiredWidth,
LayoutParams.MATCH_PARENT));
view.measure(desiredWidth, MeasureSpec.UNSPECIFIED);
totalHeight += view.getMeasuredHeight();
}
ViewGroup.LayoutParams params = listView.getLayoutParams();
params.height = totalHeight + ((listView.getDividerHeight()) * (listAdapter.getCount()));
listView.setLayoutParams(params);
listView.requestLayout();
}
Hope it works for you.

You cannot put a scrollable container in another scrollable container (a ScrollView containing a listView). Even if you can get it to work, it will create problems.
Please consider redesigning your layout, or for example dynamically add layouts for the scroll view, or get rid of the scroll view and use a list view with header and / or footer view

scroolview only allows one child. so to solve your problem, you need to create scrollview in xml inside put linearLayout and inside LinearLayout put all your content.
and to disable scrolling of the list, you can use inside MainActivty: list.setVerticalScrollBarEnabled (false);
<ScrollView
android:id="@+id/scrollView1"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:id="@+id/text_id1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/str1"
/>
<ListView
android:id="@+id/listview"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</ListView>
<TextView
android:id="@+id/text_id2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/str2" />
<ListView
android:id="@+id/listview2"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</ListView>
</LinearLayout>
</ScrollView>
