Android in the left half of the video screen to change the brightness of the right half of the slide up and down to change the sound _android

Description

Implementation features:

(1) The right part of the screen slide, the sound becomes big, down, the sound becomes small screen left half of the slide, brightness, decline, brightness becomes small

(2) If the brightness >1 or less than 0.2, the mobile phone vibration

The above is a small set to introduce the Android video screen in the left half of the slide to change the brightness of the right half of the light up and down to change the sound, I hope to help you, if you have any questions please give me a message, small series will promptly reply to everyone.
