Decompling an android apk

I am trying to Decompling an android apk with using apktool, dex2jar and jd-GUI. Its working smooth and I am getting 98% result in even java code. I have one issue is I am getting digit instead of character in some place like below.

setContentView(2130968603);

this.v.findViewById(2131689676).setBackgroundResource(2131623996);
