Rows and Columns layout in Android Widget

Question

Things are simple, I want to make a widget with 4 lines and 4 rows in it, on each cell there would be a click-able image and an action set by the user via the Settings page.

The layout is like this:

What layout element is recommended to be used for this scenario ? Should I use a GridView, TableLayout, more Linearlayouts ? Keep in mind that the spacing between items must be the same. I want to make it as light as possible. So, what layout ?

If I decide to use a GridView do you have any simple tutorial about this? I can't manage to find a way of accessing the GridView from AppWidgetProvider and set it's Adapter. Thank you.

LE: It seems that GridView is supported starting from Android 3.0.. please correct me if I'm wrong. In this case the only remaining thing to do is add 16 images and for each image add a onClickListener ? Brrr...

Answer 1

If you use a GridView then half of your work is done for you - The only layout and formatting elements you need to consider are on a Global (GridView) and Item level.

Using a GridView will also give your Scrolling functionality and the ability to change your row/columns count based on your device (4x4 on tablet, perhaps 2x8 on a phone).

Creating an extension of BaseAdapter to attach the Grid's children will also give you the flexibility to check items, multi select and will allow you to quickly modify the implementation in future by adding and removing items at will.

If this is simply a 4x4 grid which will always ALWAYS remain the same independent of device and each "Item" will always be the same, Use a RelativeLayout as it will be the most lightweight and efficient ViewGroup.
