Question

I am trying to configure my button layouts and cannot figure out why the buttons are not visible despite the lack of errors. I have tinkered around and at best only am able to get a single button to show much less all of them. Each image button references an image stored in drawable-ldpi, and each are roughly 1 KB in size.

Below is the intended layout look:

 _______________________
|        logo          |
|______________________|
|       search         |
|______________________|
|                      |
|     featured         |
|                      |
|______________________|
|    |     |     |     |
|    |     |     |     |
|    |     |     |     |
|    |     |     |     |
|    |     |     |     |
|    |     |     |     |
|    |     |     |     |
|____|_____|_____|_____|
|     advertisement    |
|______________________|

Answer 1

You have set heights and widths with 0 dps. You won’t see anything. try to solve those 0dps first.
