It would help if you posted images of which screens it doesn't support and why. But a brief look at your layout leads me to this suggestion: Don't use absolute pixel measurements. Use "dp" instead of "px". Also, read the guide topic on supporting multiple screens.

You should probably change all the places where you use px to dp.

WHen you use dp, which is short for "density independant pixels", your layout should support multiple screens.

Use dip which density independent pixels instead of px which are pixels
