Android Question [Closed] Panel with a transparent part

[asales]

Is possible to create a round panel with a transparent part, like this picture below?

If yes, how can I do this?

Thanks in advance for any tip.

All views are rectangle.

They answer is yes, but you need to tell us what exactly are you trying to do.

I want to create a wheel like this below (no need to rotate like a roulette).

I click in a button and a part of image or panel in background, will be selected (rotated) and show in the transparent part of the front panel.

You could make 2 imageview:
One with the wheel and one with the coverage with transparent slot.
Then rotate the wheel as needed.

Note that the sectors are not the same size (different angles)

Is just an example. The sectors will be the same size.

Hint: rotate the "wheel" with values and draw a "pointer":

Thanks. I saw and tried this lib several years ago, but I don't need a indicator and the rotate will not be random (I will move to selected sector).
In one open the order to rotate and show the sector will be: 1, 3, 5. On other open the order to selected the sectors will be 2, 4, 6 and so on.

Thanks. I think in a panel because I want to made modifications in runtime.
But if I am unable to use the panels, I will move on to this approach.

Thank you all!

I change my mind. I will do the panel with a transparent part using a image, like @Sagenut says.

Now my other issue will be to create a round panel with sectors (with rotate labels in every sectors) and rotate the panel to fit the sector in transparent part of the image, but I'll open a new thread to this.

It is possible to select a sector not randomly:
AwesoneWheel.Index=Value
