Android Custom view realizes alarm clock ringing function _android

First, look at the effect of the alarm clock page

Features to implement:

1: Turning pictures According to weather conditions change

2: Turning time can be set, the end of rotation, alarm sound on the end

3: Aperture Color Gradient effect

Directly on the code:

The above is a small set to introduce the Android custom view to realize the alarm clock ringing function, I hope to help you, if you have any questions please give me a message, small series will promptly reply to everyone. Here also thank you very much for the cloud Habitat Community website support!
