There is no API provided by android SDK. The system build-in Settings provides 
such functionality for screen lock in Settings -> Location & Security -> Change 
Screen Lock.

After tracking the Android source code, I found they create a custom view to do 
this. So follow this idea.

frameworks/base/core/java/com/android/internal/widget/LockPatternView.java
packages/apps/Settings/src/com/android/settings/ChooseLockPattern.java

I was looking at this right here: 
http://developer.android.com/guide/topics/admin/device-admin.html

It's the admin interface to android I think this may be a better solution but I 
will look at both.

That works on android 2.2 and after, but we are working on android 1.5.  The 
device admin also uses the internal view class LockPatternView, but it can not 
be customized by showing the label and icon of the application being locked by 
use.

When we lock the application being launched by user, we need to tell the user 
what we do (lock the application), and what we need the user do (input the 
pattern password).

I think building a custom view is also a good way to reach the internal part, 
as well as understand View class a little bit more.

This was done already by someone else, just taking it off of the issues list.
