the weight property is missing in the textview in ny ADT and I can not set the percentage of the weight

Actually it could probably be opposite: yours is newer than videos. There are some differences between us and over there in the video due to this.

You can easily add it yourself simply by writing those property in the TextView element. Or manipulate it within the weight property in the property window right-down of the eclipse.

Thanks for the answer. On my PC, if I type in the android:weight in the textview, the eclipse will flag error to that line. However, there is a layout_weight in the textview property but that was not what Ben used in the video. I put that in anyway, the app did not crash, but I could not tell whether it works actually....::))

That's because it should be android:layout_weight="value" Not android: weight="value"
