I've managed to implement a great listview that I found here 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(); } }); } 6 Answers
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(); } }); 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 } 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.
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 } }); You are doing
Object o = prestListView.getItemAtPosition(position); String str=(String)o;//As you are using Default String Adapter The o that you get back is not a String, but a prestationEco so you get a CCE when doing the (String)o
Try this:
list.setOnItemSelectedListener(new OnItemSelectedListener() { @Override public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) } @Override public void onNothingSelected(AdapterView<?> arg0) { } });
