Android: onListItemClick in Activity

Question

Previous time I asked a question here I learned a lot so I guess it\'s worth a shot to try it again.

I am using the lazy list by Fedor from this link: Lazy load of i

Answer 1

A listItemClickListener is attached to a ListView. When you changed ListActivity to Activity, your class no longer has a view associated with it and thus an Activity class has no idea what to do with an onListItemClickListener.

You just have to attached a listener to your ListView:

listview.setOnItemClickListener(new OnItemClickListener(){
    @Override
    protected void onListItemClick(AdapterView<?> parent, View view, int position, long id){
        //Do stuff
    }
});

Answer 2

Assume you have datasource Fruit contain few strings. You can define the onCreate() as following:

setListAdapter(new ArrayAdapter<String>(this, R.layout.list_fruit,
                FRUITS)); // context is this, style is list_fruit, Context, ,data_binding to FRUITs

And then write the onListItemClick() as following:

protected void onListItemClick(ListView parent, View v, int position, long id) {
                Toast.makeText(this,  " You selected  " + FRUITS[position], Toast.LENGTH_SHORT).show();
        }

I hope it works for you :)
