To achieve horizontal navigation between the different planets while having their corresponding moons above them (and hence more intuitive as the solar system is often represented with a relatively horizontal orbital plane), we rotate the obligate vertical GridViewPager view 270 degrees; up/down swipes become left/right swipes, flipping the planets into the familiar horizontal orbital plane.

Android's DotsPageIndicator thus currently shows navigation within a planetary system only (e.g., Mars - Phobos - Deimos). We need a vertical page indicator to show the intraplanet navigation (Earth - Mars - Jupiter) and, lo and behold... DotsPageIndicatorVertical.

Unfortunately, did not succeed to include this new dependency as jar, aar or url, so filed zhoulujue/DotsPageIndicatorVertical#1 and moving on to #10 in the mean time. Will revisit upon activity on the former or completion of the latter.

Heed dev note: There may be conflicts between DotsPageIndicator and DotsPageIndicatorVertical as Android's indicator currently steals the adapter's page scroll listeners.

... even if it's from its simulated surface.

• Remove text white background
• Make text white
• Move text to top
• Make text lowercase
• Resize planets to avoid overlapping with text

Now that moons are correctly displayed over their corresponding planets, we can finally add more content... At least the "main" moons for the four giants!

So planet or moon is shown by itself in full-screen glory if left for a few seconds.

When a planet first loads, it fades from black into view. Subsequent loads (once it's already cached), it just abruptly appears.

Update background loading so it returns a black background but then fades in the planet, just like when it first loads.

Only if it's possible to either hide the first dot (for the planet itself) or make that icon a dot while the others are moons.

Make an overlay that appears when tapped showing planet name and stats.
