How to make some list items without clicks?

I have the following code that is pretty easy to understand. I want some particular child of this list not to be clickable.

    ArrayAdapter<String> adapter =
      new ArrayAdapter<String>(this,R.layout.list_item,R.id.module_name_item, testdata);

    m_listview.setAdapter(adapter);


    Log.i("check","1");
    if(sectionAttempts.get(0).equals("0"))
    {

        m_listview.getChildAt(2).setEnabled(false);
        m_listview.getChildAt(3).setEnabled(false);
    }
    else
    {

        if(sectionAttempts.get(2).equals("0"))
        {

            m_listview.getChildAt(3).setEnabled(false);
        }


    }

I get an error in

  m_listview.getChildAt(2).setEnabled(false);

like java.lang.NullpointerException. I tried to find the error and used Log.i ("check", m_listview.getChildCount ()); And it shows 0., so I guess the listview has not been created yet! How is this possible.

What is the problem? Thanx for any help in advance.

Override the method areAllItemsSelectable(). Return false to say that all items are not viewable.

@Override
public boolean areAllItemsSelectable() {
    return false;
}

And then override the method below to return the element that cannot be clicked

@Override
public boolean isEnabled(int position) {
    if(position == your_item_pos) {
        return false;
    }
    return true;
}

It seems that you did not initialize the ListView. In onCreateuse m_listview=getListView(), if you use ListActivity or m_listview=findViewById(R.id...)if you are using a regular activity.
