setListAdapter(new ArrayAdapter<String>(this,layout.main,
id.ScrollView01, mStrings));

ListView cities = (ListView) findViewById(R.id.ListView02);

ArrayAdapter<String> aa = new ArrayAdapter<String>(this, layout.main,
id.ListView02, mStrings2);

cities.setAdapter(aa);



its not working properly, i add the sample code of my problem please check it out.

[neelima kant]

package com.example.hellotwolistviews;

@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.main);

//setListAdapter for ListView 1
setListAdapter(new ArrayAdapter<String>(this, .layout.main,
.id.ScrollView01, mStrings));
//Code to display ListView 2
ListView cities = (ListView) findViewById(R.id.ListView02);
ArrayAdapter<String> aa = new ArrayAdapter<String>(this, .layout.main,
.id.ListView02, mStrings2);
cities.setAdapter(aa);


}

}

Add a view between two lists

 
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

</TableLayout>
</ScrollView>

[neelima kant]

if i want to make the second list checkable then i modify my code as

ArrayAdapter list2 = new ArrayAdapter<String>(
this, android.R.layout.simple_list_item_multiple_choice,mStrings2);
final ListView listView = getListView();

listView.setItemsCanFocus(false);
listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);

lv1.setAdapter(list1);
lv2.setAdapter(list2);


but its not working???

[Swastik Dey]

By checkable do mean you want checkboxes besides the text in list box?

[neelima kant]

yes with checkboxes....my code is not working properly.

[neelima kant]

i want to made the second list with multiple choices...using choice_mode_multiple.....

[Swastik Dey]

try this

  
public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.test);	
		ListView lv1=(ListView)this.findViewById(R.id.ListView01);
		ListView lv2=(ListView)this.findViewById(R.id.ListView02);
		ArrayAdapter list1 = new ArrayAdapter<String>(		
				this, android.R.layout.simple_list_item_1,mStrings);
		ArrayAdapter list2 = new ArrayAdapter<String>(		
				this, android.R.layout.simple_list_item_checked,mStrings2);
		lv1.setAdapter(list1);
		lv2.setAdapter(list2);
		lv2.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
	}
  

[neelima kant]

thanks ....it work properly now.

if i want that the checked item of the second list move to the first list??? then how should i proceed??? i m taking my first list as empty list.

[Swastik Dey]

			}
			
		});
	}

	private void repopulateFirstList(ListView lv,int selectedIndex){

[neelima kant]

yes it works properly now thanks. can you tell me what is the significance of using tablelayout in xml file.

[Swastik Dey]

As you have two lists, you need a scroll view to add the components. But on the other hand scroll view won't allow to add more than one component. So we took a table layout and added it to scroll view. Now the scroll view has only one component, and we added the list views to table layout which allows to add multiple components. I hope it helps you to understand the reason.

[neelima kant]

instead of using table layout i use framelayout in my application but it works not properly......we cant use framlelayout for this why???

[neelima kant]

how i made the association among two lists if i considered that first list containing the selected components of second list....

[Swastik Dey]

To be honest I am also pretty new on android, so won't be able to exactly tell you why frame layout didn't work. Coming to your second question there is no question of association, we are just resetting the adapters.
