Android - how to add an item click method to an ArrayAdapter

Question

I have a simple ArrayAdapter. I want to set up a listener for every row click of my list such that a new Activity opens. How would I do that? My ArrayAdapter code -

Answer 1

Simply implement AdapterView.OnItemClickListener.

@Override
public void onItemClick(AdapterView<?> adapterView, View view, int pos, long l) {
    Intent i = new Intent(this, ProductActivity.class);
    i.putExtra("item_id", manager.getItemIdAtIndex(pos));
    startActivity(i);
}

Then just set the class with that method as the onItemClickListener in your adaptor.

Assuming you are using a ListActivity implementing OnItemClickListener you could use this code:

ArrayAdapter<Object> ad = new ArrayAdapter<Object>(this,
                android.R.layout.simple_list_item_checked, items);
        setListAdapter(ad);
        ListView list = getListView();
        list.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
        //list.setItemChecked(0, true);
        list.setOnItemClickListener(this);

EDIT: Otherwise, if you don't extend ListActivity, have a listview in your layout and replace ListView list = getListView() with something like ListView list = findViewById(R.id.listView). Replace list.setOnItemClickListener(this) with

list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

            }
        });

Once you have set your adapter using:

mListView.setAdapter(myCountryListAdapter); 

Then you can setup a click listener for the listview:

mListView.setOnParentClickListener(new  OnClickListener() {         
    public void onClick(View view,) {
            ///do what you want the click to do
    }       
    });
