Android: load, manipulate and use Image

I have a value in my Activity which represents the "progress" of a certain player in context of a goal to achieve (e.g., a player needs 10 wins, he got 3 wins -> progress = 30%).

What I want now is to load an "empty" Image and fill it relative to the progress value.

E.g.

enter image description here

is manipulated to

enter image description here

But now I absolutely don't know how to achieve this. I had in mind that the easiest way would be a Java-function with parameter progress that loads that empty image and draws x vertical lines (whereby x is = progress as int) on that image and returns it.

Now I've read some Tutorials, but I still don't get how I can load that png, draw some stuff on it and return it whitout saving the drawings in it. Has anyone an idea how to perform this?

You can use the Android progress bar feature. http://developer.android.com/reference/android/widget/ProgressBar.html

If you don't want it in a dialog then you can embed it directly.

Here is a another answer that may help: Android progress bar embedded in ui and not in dialog

Here is how to create a custom progress dialog: Custom Drawable for ProgressBar/ProgressDialog

Hope that helps.
