Iterating ListView items in Android
- by pocoa
I want to iterate a list of items into a ListView. This code below is not enough to iterate all the items into the list because of the weird behaviour of getChildCount() function which only returns the visible item count. for (int i = 0; i < list.getChildCount(); i++) { item = (View)list.getChildAt(i); product = (Product)item.getTag(); // make some visual changes if product.id == someProductId } My screen displays 7 results and when there are more than 7 items into the list, it's not possible to access to the 8th item or so.. Only visible items.. Should I use ListIterator instead? Thanks.Read the article

What is the difference between these usages: new SubElement() and SubElement()?
- by pocoa
Into a class constructor, I need to create some objects on the fly and add them to a vector. Here is my code: ContainerClass::ContainerClass() { for (int i = 0; i < limit; i++) elements.push_back(SubElement()); } Is this the same thing with new SubElement()? Do I still need to free those SubElement() objects into the ContainerClass destructor?Read the article
