Adding an onclicklistener to listview (android)

Question

I've managed to implement a great listview that I found here http://www.learn-android.com/2011/11/22/lots-of-lists-custom-adapter/comment-page-1/ but I can't seem to add an onclicklistener I just want to be able to do an action when I click on the row, with the data that the row contains of course any ideas? thanks

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.liste);
    this.requestWindowFeature(Window.FEATURE_NO_TITLE);
    // Setup the list view
    final ListView prestListView = (ListView) findViewById(R.id.list);
    final prestationAdapterEco prestationAdapterEco = new prestationAdapterEco(this, R.layout.prestation);

    prestListView.setAdapter(prestationAdapterEco);

    // Populate the list, through the adapter
    for(final prestationEco entry : getPrestations()) {
        prestationAdapterEco.add(entry);
    }
    prestListView.setClickable(true);
    prestListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) {
            Object o = prestListView.getItemAtPosition(position);
            String str=(String)o;//As you are using Default String Adapter
            Toast.makeText(getApplicationContext(),str,Toast.LENGTH_SHORT).show();
        }
    });
}

Solution 1

listView.setOnItemClickListener(new OnItemClickListener() {

    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        Object o = prestListView.getItemAtPosition(position);
        prestationEco str = (prestationEco)o; //As you are using Default String Adapter
        Toast.makeText(getBaseContext(),str.getTitle(),Toast.LENGTH_SHORT).show();
    }
});

Solution 2

If your Activity extends ListActivity, you can simply override the OnListItemClick() method like so:

/** {@inheritDoc} */
@Override  
protected void onListItemClick(ListView l, View v, int pos, long id) {  
    super.onListItemClick(l, v, pos, id);

    // TODO : Logic
}  

Solution 3

The prestListView.getItemAtPosition(position); returns the UI widget: Text, Icon, ...

Try this instead:

Object o = prestationAdapterEco.getItemAtPosition(position);

or

Object o = arg0.getItemAtPosition(position);

Get the object from the adapter. Not from the list-view.

2. Object o is a prestationEco object. Not a String.

Solution 4

list.setOnItemSelectedListener(new OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> arg0, View arg1,
                int arg2, long arg3) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub

        }
    });
