Question

Feed in Four Square android app looks like this:

A rectangular box with actual post, below which is a Text like 10 people like this and so on.

Is this just a listView with Actual content having margins and a different background, and TextViews below it.

Because when i had a complicated ListView with an ImageView and 5-6 TextViews, it takes lot of time to load the UI.

1 of my friends who work on iOs said Instead of Custom ListView Items, use ImageView which look like a Custom View with images and textviews. Which makes loading lot faster. But ofcourse it takes lot to implement such thing.

I just want to know, if its just another custom listview?

And that my delay to load the UI is because of someother reason?

Such techniques are available in android too??

Thank You

Could be a ListView with complicated children views. Could also be an ExpandableListView.

There’s a few reasons why it may load faster than something you’ve used before:

1. The images were probably already cached on the file system, so it loads from local storage rather than downloading the image.
2. The images were already the correct dimensions, so no resizing was needed.
3. Image loading was done on a background thread as to not lag the UI while images were being loaded into memory.
