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();
}
});
}

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) {
}
});
