I have created some text files in the SD card, but I am unable to view my files.

I am using this path Environment.getExternalStorageDirectory(); to create files.

I am not getting any exception while creating files.

when I open the DDMS in eclipse I am unable to see my files there also..

If I created the files at 

Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);

then I can see my files at /data folder of the device , but not in SD card itself.

When I click on the gallery icon in my device, I can see only pictures, videos, camera shots folders only but not my files ..

please suggest is that the proper way of creating files in SD card. thanks.

Environment.getExternalStorageDirectory() doesn't always return the location to an external card. On android tablets (Android 3.0+) this directory is often mounted in the internal memory.

From the docs:

Note: don't be confused by the word "external" here. This directory can better be thought as media/shared storage. It is a filesystem that can hold a relatively large amount of data and that is shared across all applications (does not enforce permissions). Traditionally this is an SD card, but it may also be implemented as built-in storage in a device that is distinct from the protected internal storage and can be mounted as a filesystem on a computer.

AFAIK there is no generic way to determine the mountpoint of an sdcard, this is specified by the device manufacturer. For example the ASUS Transformer mounts the external cards in /Removable/MicroSD and /Removable/SD . The "External Storage" directory /sdcard/ is mounted in internal space.
