You just need to setOnClickListener for the button in getView() method of ItemListBaseAdapter1 like this.

    class ItemListBaseAdapter1 extends BaseAdapter
    {

    private Activity mActivity;
    public ItemListBaseAdapter1(Activity activity, ...)
    {
        mActivity = activity;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent)
    {
        // TODO: get view here
        final Recipedetails1 item = (Recipedetails1) getItem(position);
        theButton.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v)
            {
                Intent intent = new Intent(mActivity, [your activity class]);
                intent.putExtra("The Link Key", item.getUrlWiki());
                mActivity.startActivity(intent);
            }
        });
        return view;
    }

}

And on the target Activity you get link by this:

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    String link = getIntent.getString("The Link Key", null);
}

you need to add android:descendantFocusability="blocksDescendants"

I just found solution from here

Use this to pass your contains intent.putExtra("TAG", Data);

As you said, you have a button in a list item of list. as u know on button click listener u got view in method of onclicklistener

new OnClickListener()
{
@Override
public void onClick(View view)
{}
}

here view has a method of getparent() which returns you a view in which your button is set. you can check it by printing in log. if u got parent of button then u can also get all child views of parent in which 1 child view is button. from all child views u can get there values to send them in next activity. if button's parent has another parent in view of list item then u can also get parent of parent view by calling a getparent() method.

Please keep in mind that views have parent child relation so if you wants all child then you have to get parent.
