ListView not displaying all items in Landscape mode

Question

I have an Activity that fits the screen size in portrait mode like shown in image below

Problem is when i rotate screen, the ListView collapses and displays only one item like shown in image below

What is causing this issue and how can i fix it ?

Answer 1

So i solved the issue mentioned in my question by having

1- Separate layout file for landscape mode. Made a a new folder named layout-land inside res folder and then copied the layout file included in my question in to layout-land folder and then made appropriate changes according to landscape portrait.

2- Having fixed height for ListView. In my case i set the height of ListView to 190dp.

Now my layout in landscape looks like shown in image below
