Hi all,
I have read on this site that it is necessary to customize the setOnItemSelectedListener and setOnItemClickListener of a ListView if we want to know the Index of the SelectedItem (.getSelectedItemPosition()). So that is what I do but it does not stores the position of the SekectedItem, instead i have always -1...
What I want to do is just to give the user a way to delete items from a list by selected and Item and Clicking a button.
See the code below :
listViewPeople.setOnItemClickListener(new ListView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> a, View v, int i, long l) {
try {
// Remembers the selected Index
listViewPeopleId = listViewPeople.getSelectedItemPosition();
}
catch(Exception e) {
System.out.println("Nay, cannot get the selected index");
}
}
});
listViewPeople.setOnItemSelectedListener(new ListView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> a, View v, int i, long l) {
try {
// Remembers the selected Index
listViewPeopleId = listViewPeople.getSelectedItemPosition();
System.out.println("Yay, set the selected index " + listViewPeopleId);
}
catch(Exception e) {
System.out.println("Nay, cannot get the selected index " + listViewPeopleId);
}
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
try {
// Remembers nothing selected
listViewPeopleId = -1;
System.out.println("Yay, set that nothing is selected " + listViewPeopleId);
}
catch(Exception e) {
System.out.println("Nay, cannot set that nothing is selected " + listViewPeopleId);
}
}
});
What's wrong??
Thank you for your help!
