Answer 1

Try this replace your ProgressBar with the one below.

Let me know if it works, I would explain the rationale.

Rationale: Now I am putting your code below for ProgressBar

RelativeLayout allows you Z-ordering. So since you needed ProgressBar on top you need not do the kind of manipulations you are doing.

android:layout_alignParentBottom="true"  

This sets the Progress Bar at the botton of the layout:

android:paddingBottom="450dip" android:layout_width="200dip" android:layout_height="200dip"

All the three values here are absolute which is a strict no-no as far as Android is concerned. Most Likely your paddingBottom was pushing your ProgressBar out of View. As your padding is greater than the actual width/height of the control

As a thumb rule always use relative values for it to work on all the devices and form factors.

Let me know if this makes sense.
