Can we implement Thread in Arduino Mega2560

Please let me know can we make Thread for background activity in ArduinoMega2560 like implemented in Android Operating System.

I can't help you with the code, I'm not familiar with Android OS or Mega2560 but I think you can 'thread' or 'task' just about any processor. I have even run background tasks on a 6502 processor and PIC16F84 before now. All you need to do is set up a timed interrupt to switch tasks, save the registers and jump to the other code. There you restore its copy of the registers and continue running its code. Pre-emptive task switching is a little more difficult but not impossible on an MCU.

I download a Thread library it is running but I also used MultiKeypad library, in this library getKey function stops all processing even Thread is not working how to handle this situation. I am struggling but I need hints.

I'm sure there is something too wrong with your code, reading 'keys' are rather non-blocking procedures.
In addition, much likely you don't strictly need to handle with 'threads' with Arduino, you can perform time slotting with timer interrupts.

I am using this attached Keypad library it is blocking my code do you know any other library Multikeypad

I did not spent time to check the attachment, in except to confirm that your read key library have houndred lines of code.
I would start with something simplest, as this one, which perhaps has no more than a dozen lines.
