    One possible implementation is as follows:

    • Create an invisible sphere. The sphere’s vertices are calculated as positions for the labels but not drawn. You can find the sphere algorithm in several answers in SO, e.g here.
    • Attach the labels to different points on the sphere, each label always facing the camera.
    • Rotate the sphere based on user drag action
    • Fade the words based on z value.
    • Tapping a label will rotate the invisible sphere to bring the label to the front.

    This can be implemented either in a SurfaceView, or GLSurfaceView with OpenGL. If you use SurfaceView you probably need to keep the number of labels/vertices low to make it run smoothly.

    Here is a tutorial on how to create a rotating tag sphere for Android.
