Question

I have a ListView with two elements. I would like to execute different code based on the item that has been selected. Until now my code looks like this (but it is not working):

protected void onListItemClick(ListView l, View v, int position, long id) {
     // TODO Auto-generated method stub
        ListView listview = (ListView) findViewById(android.R.id.list);
        View root = (View) listview.getParent();
        if (position == 1) {
            root.setBackgroundColor(Color.parseColor("#133b96"));
        } else if (position == 2) {
            root.setBackgroundColor(Color.parseColor("#bdbdbd"));
        }
    }

I want to change the background color, and the color should be based on the selected item.

What is the simplest way to do this?

Answer 1

protected void onListItemClick(ListView l, View v, int position, long id) {

    if (position == 1) {
        v.setBackgroundColor(Color.parseColor("#133b96"));
    } else if (position == 2) {
        v.setBackgroundColor(Color.parseColor("#bdbdbd"));
    }
}

Just look at your protected void onListItemClick() methods for parameters View v. Which is a Selected list item’s View. And if you want to change background color of ListView then use

ListView l.

something like,

if (position == 1) {
        l.setBackgroundColor(Color.parseColor("#133b96"));
    } else if (position == 2) {
        l.setBackgroundColor(Color.parseColor("#bdbdbd"));
}

So you have to remove additional code from it to get it to work.
