Android uses surfaceview+mediaplayer+ custom Mediacontroller to implement a custom video player

As follows:

(PS is supposed to give everyone to wear GIF dynamic diagram, but too big, unable to upload)

Feature implementation: Pause, play, fast forward, rewind, fullscreen, exit fullscreen, etc. basic functions

Realization of the idea:

Place a surfaceview in the main layout, place a mediaplayer in the Surfaceview, and customize a mediacontroller underneath it, but it's not called Mediacontroller, Using Pupupwindow to implement, put a few textview,button in the Pupupwindow layout, the most important to make our Seekbar control, create a timer when the user touches the screen, let it popupwindow display 5 Seconds of time , the concrete implementation can look at the code (the main program code a little more, patience to see AH)

Main layout Activity_main.xml file
