Two columns for ListView or TableLayout in Landscape mode

Question

How can I get one column in portrait mode and two columns in landscape mode with a ListView or TableLayout .

For example, in Portrait:

• Element 1
• Element 2
• Element 3
• Element 4

And in Landscape :

• Element1 Element2
• Element3 Element4

I thought to use ListView with one column in portrait mode and TableLayout with two columns in landscape mode, but before that, I want to know your suggestions.

Answer 1

I recommend using a ListView rather than a TableLayout, since ListViews only create enough Views to fill the screen while a TableLayout will create every resource whether they are visible or not. In this way a TableLayout is slower and might even crash your app.

You can check the device's orientation with one of the answers from: Check orientation on Android phone . Then if the orientation is:

• landscape, load your double View layout.
• portrait, load your basic, single View layout.

Loading different layouts in a ListView requires a simple custom Adapter. If you haven't written one before, here is a tutorial to help you.

Answer 2

It'd be way easy for you to use a GridView. You can set/choose number of columns on runtime and hence set them differently in portait vs landscape mode. That way, you'd just be manipulating a single view.
