Use Surfaceview and MediaPlayer to implement video as a backdrop

Scenario: Like we started with the Uber app, we saw a video as the beginning. This lets the user very quickly into the application use of the scene, such as video as the opening of the application, we do not think very tall, haha, in fact, the use of Serfaceview to load a small video, and then use MediaPlayer to play. And then loop.

Go ahead.

Here I post the implementation of the main code

Import Java.io.ioexception;import Android.app.activity;import Android.content.intent;import Android.content.res.assetfiledescriptor;import Android.media.audiomanager;import Android.media.MediaPlayer; Import Android.media.mediaplayer.onpreparedlistener;import Android.os.bundle;import Android.view.SurfaceHolder; Import Android.view.surfaceview;import Android.view.view;import Android.view.view.onclicklistener;import Android.widget.button;public class Mainactivity extends Activity implements Onclicklistener {private Surfaceview Surfaceview;private Button btngo;private MediaPlayer mediaplayer;private int postion = 0; @Overrideprotected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate); Setcontentview (R.layout.activity_main); Findviewbyid (); Initview ();} protected void Findviewbyid () {//TODO auto-generated method Stubsurfaceview = (Surfaceview) Findviewbyid ( R.id.surfaceview); Btngo = (Button) Findviewbyid (R.id.btn_goto);} protected void Initview () {//TODO auto-generated mEthod Stubmediaplayer = new MediaPlayer (); Surfaceview.getholder (). Setkeepscreenon (True); Surfaceview.getholder (). Addcallback (New Surfaceviewlis ()); Btngo.setonclicklistener (this);} Private class Surfaceviewlis implements Surfaceholder.callback {@Overridepublic void surfacechanged (Surfaceholder Holder, int format, int width,int height) {} @Overridepublic void surfacecreated (Surfaceholder holder) {if (postion = = 0) { try {play ()} catch (IllegalArgumentException e) {//TODO auto-generated catch Blocke.printstacktrace ();} catch (Security Exception e) {//Todo auto-generated catch Blocke.printstacktrace ();} catch (IllegalStateException e) {//Todo Auto-genera Ted Catch Blocke.printstacktrace ();} catch (IOException e) {//TODO auto-generated catch Blocke.printstacktrace ();}}} @Overridepublic void surfacedestroyed (Surfaceholder holder) {}}public void Play () throws IllegalArgumentException, Securityexception,illegalstateexception, IOException {mediaplayer.setaudiostreamtype (AudioManager.STREAM_MUSIC); Assetfiledescriptor fd = This.getassets (). OPENFD ("Start.mp4"); Mediaplayer.setdatasource (Fd.getfiledescriptor (), Fd.getstartoffset (), fd.getlength ()); mediaplayer.setlooping (true); Mediaplayer.setdisplay (Surfaceview.getholder ( );//Load the Media Resource Mediaplayer.prepareasync () by asynchronous mode; Mediaplayer.setonpreparedlistener (new Onpreparedlistener () {@ overridepublic void onprepared (MediaPlayer MP) {//Load complete callback Mediaplayer.start ();});} @Overridepublic void OnClick (View v) {switch (V.getid ()) {case r.id.btn_goto:startactivity (the new Intent (this, Otheractivity.class)); finish (); break;default:break;}}}
