You can use this for your case

@Override
public void onBackPressed() {

    if (myCase) {
        // add your specific treatment
    } else {
        // the normal case the BackPressed
        super.onBackPressed();
    }
}

If looking for android api level upto 1.6.

@Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
         if (keyCode == KeyEvent.KEYCODE_BACK) {
         //preventing default implementation previous to android.os.Build.VERSION_CODES.ECLAIR
         return true;
         }
         return super.onKeyDown(keyCode, event);    
    }

And if looking for a higher api level 2.0 and above this will work great

 @Override
    public void onBackPressed() {
  // Do Here what ever you want do on back press;
}

You have to Override the onBackPressed method and leave it blank.

@Override
public void onBackPressed () {
    // Do nothing here.
}

If you leave the method unimplemented, then it will disable the Back key. You can write any code inside this method to do any task you want according to your logic.

Use this:

@Override 
public void onBackPressed(){
    super.onBackPressed();

    //do what you want to do here.

}
