Android video playback and progress bar Synchronization

First, get the video playback length to set the max and videobbar of seekbar. setmax (mediaplayer. getduration (), and then obtain the video playing time in real time through the thread to update seekbar and videobbar. setprogress (mediaplayer. the getcurrentposition () method is as follows.CodeAs follows:

Videobbar = (seekbar) findviewbyid (R. Id. seekbarplayprogress );

surfaceview = (surfaceview) findviewbyid (R. id. player);
surfaceview. getholder (). addcallback (New playcallback ();
surfaceview. getholder ()
. settype (surfaceholder. surface_type_push_buffers);
surfaceview. getholder (). setfixedsize (surfaceview. getwidth (), surfaceview. getheight ();
mediaplayer = new mediaplayer ();
mediaplayer. setaudiostreamtype (audiomanager. stream_music);
mediaplayer. setdisplay (surfaceview. getholder ();
try {
mediaplayer. setdatasource ("/sdcard/movie/ _1.mp4");
mediaplayer. prepare ();
mediaplayer. start ();
videobbar. setmax (mediaplayer. getduration ();

Videothreed = new videothreed ();
Videothreed. Start ();
}
Catch (exception E)
{
Toast. maketext (this, "playing error! ", Toast. length_long). Show ();
}
