I recently saw the usage of ViewFlipper and Animation together, and I wrote it myself. It seems very gray and easy to use, and the effect is much better than that of gallery scrolling and viewing images, this also enables switching between images on the scrolling screen, but the user experience is much better! So I will share my own demo! I hope it will be useful to you and it will be easier for me to check it later! Reprinted please indicate the source:

At the beginning of the program interface, the first image slides to the right and switches to the second image:

Slide to the right to switch the third image:

Slide left and switch to the second picture!

And so on!
