While executing the sample IP example I am not getting the data out value while reading. Empty signal is remaining continuously '1'. How to perform read operation in FIFO generator IP properly?

Fifo generator to work properly , you have to follow the reset guidelines given in FIFO generator IP.
The reset guidelines are different for different configuration in the FIFO generator.
There is "Reset" section starting from page 127. Check the reset guidelines for configurations you are aimed to.
Additionally for your particular configuration you can generate the IP example design where testbench is provide , you can refer that as well.
To open the IP example design , right click to IP-> Open IP example design.

I did simulation of IP example and for that only I was not getting dout. It is continuously showing 0 in waveforms and other than that empty signal is also remaining 1.

Send me your IP configuration file (.XCI) file or sent the IP configuration tab pictures and let me know the VIVADO version you are using .
and Third party simulator details if you are using for simulation.

This is just the basic tab . Please provide all Tab details (Native port , status flag...) or provide .xci file.
I sent you the FTP link to attach your XCI.
Additionally provide simulator details.

Thanks for sharing the XCI and waveforms.
I checked in latest version (VIVADO 2019.2) and VIVADO 2018.2 you are using .
In latest version , I am observing the expected simulation results
In VIVADO 2018.2 simulation results are also intended.
Run the simulation longer , wr_en is asserted at about 35.us.
In your simulation you are only checking first 20us
