I am pretty darned new
to android, and VERY new
to Parse. I have created a class, StudentInformation, that includes columns for name, address, phone, etc.
I would like
to create a listview that contains the names of all students added
to the class.
How do I do this? I have got it
to the point that I can Toast out the objectIDs of all of my entries, but can't figure out
how to extract and add just the names
to the ListView.
Here is a snippet of the code:
//Set up the listview
studentListView = (ListView)findViewById(R.id.listViewStudents);
//Create and populate an ArrayList of objects from parse
ParseQuery query = new ParseQuery("StudentInformation");
final ArrayList<Object> studentList = new ArrayList<Object>();
query.findInBackground(new FindCallback() {
public void done(List<ParseObject> objects, ParseException e) {
if (e == null) {
Toast.makeText(getApplicationContext(), objects.toString(), Toast.LENGTH_LONG).show();
for(int i = 0;i < objects.size(); i++){
objects.get(i);
studentList.add("name".toString());
}
} else {
Toast.makeText(getApplicationContext(), "Error", Toast.LENGTH_LONG).show();
}
}
});
//studentList.addAll(Arrays.asList(students));
listAdapter = new ArrayAdapter<Object>(this,android.R.layout.simple_list_item_1,studentList);
studentListView.setAdapter(listAdapter);
}
I have left the toast in where I toatst out the objectIDs in the public void done.... method.
Any help would be, as always, greatly appreciated.
Should be mentioned (possibly), no errors are thrown, the listview just never gets populated after the toast disappears.
Don't know if this will help anyone, but I took a bit from both posts below, and came up with this:
//Set up the listview
studentList = new ArrayList<String>();
//Create and populate an ArrayList of objects from parse
listAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1);
studentListView = (ListView)findViewById(R.id.listViewStudents);
studentListView.setAdapter(listAdapter);
final ParseQuery query = new ParseQuery("StudentInformation");
query.findInBackground(new FindCallback() {
public void done(List<ParseObject> objects, ParseException e) {
if (e == null) {
//Toast.makeText(getApplicationContext(), objects.toString(), Toast.LENGTH_LONG).show();
for (int i = 0; i < objects.size(); i++) {
Object object = objects.get(i);
String name = ((ParseObject) object).getString("name").toString();
listAdapter.add(name);
}
} else {
Toast.makeText(getApplicationContext(), "Error", Toast.LENGTH_LONG).show();
}
}
});
