google chrome animation effect in android

Question

Ich versuche create animation genau wie in Google Chrome beim Öffnen von 2 oder mehr Tabs verwendet. Hier ist das Bild unten.

Wie könnte ich diesen Effekt wie in Google Chrome machen. Sie animierte wie SlidingDrawer (aber es ist kein slidingDrawer soweit ich weiß.)

Answer 1

Es ist nicht genau wie Google Chrom-Effekt, aber vielleicht hilfreich jemand in der Zukunft.
