CHAPTER 10: Android Animation: Making Your UI Designs Move 389

3. Now you are ready to create the anim_lightship.xml file. The easiest way to
   do this is to copy the tags from the inside of the anim_andromeda.xml
   file and change lunarlander to energyship and change the value for the
   duration parameter to 200 milliseconds, which is 5 FPS (frames per second).
   Copy the eighth frame and paste it three more times underneath itself to
   create the ninth through eleventh frames, as seen in Figure 10-30.

Figure 10-31. Use the left-facing chevron < character inside of the parent tag to open the transforms dialog

Figure 10-30. Create 11 child tags for the frames of the AnimationDrawable and set the duration to 200

4. Now that the AnimationDrawable object is configured using XML, click on the
   anim_lightshipset.xml tab at the top of Eclipse, and switch over into editing
   the Animation object XML (bootstrap) definition file, shown in Figure 1 0-3 1.
   This Animation object is actually an AnimationSet object, as it uses the parent tag to hold the child transform tags; in this case, these will be a
   and transform as well as an tag.
