Android Play Video

Two ways to play Video:

Play video with Videoview (convenient, recommended)

Play video using MediaPlayer and Surfaceview (early way)

The first way:

The process of using Videoview to play video is as follows:

Define the Videoview component in the interface layout file, or create a Videoview build in the program

Call Videoview For example the following two methods to load a specified video

Setvideopath (String paht): Loads the video represented by the path file

Setvideouri (URI uri): load the corresponding video for the URI

Call Videoview's start (), Stop (), pause () method to control video playback

Mediacontraller class

Another Mediacontraller class, used in conjunction with Videoview, provides a friendly graphical control interface to control video playback, Fast forward keys, pause keys, back keys, and playback progress.

are provided by this class

Sample code:

XML layout:

<?xml version= "1.0" encoding= "Utf-8"? ><linearlayoutxmlns:android= "http://schemas.android.com/apk/res/ Android "android:orientation=" vertical "android:layout_width=" match_parent "android:layout_height=" Match_parent " ><!--definition videoview play video--><videoviewandroid:id= "@+id/video" android:layout_width= "Match_parent" Android : layout_height= "Match_parent"/></linearlayout>

Activity:

Import Java.io.file;import android.app.activity;import android.graphics.pixelformat;import android.os.Bundle; Import Android.widget.mediacontroller;import Android.widget.videoview;public class Vedioviewtest extends Activity {Vi    Deoview Videoview;    Mediacontroller Mcontroller;        @Override public void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate);        GetWindow (). SetFormat (pixelformat.translucent);        Setcontentview (R.layout.main);        Get interface on Videoview component Videoview = (videoview) Findviewbyid (R.id.video);        Create Mediacontroller Object mcontroller = new Mediacontroller (this);        File Video = new file ("/mnt/sdcard/movie.mp4"); if (video.exists ()) {Videoview.setvideopath (Video.getabsolutepath ());//①//set Videoview and Mcontrolle R Establish Association Videoview.setmediacontroller (Mcontroller); ②//set Mcontroller with Videoview to establish Association Mcontroller.setmediaplayer (Videoview);      ③      Let Videoview get focus videoview.requestfocus (); }    }}

Another way:

The process of using MediaPlayer to play video is as follows:

Create a MediaPlayer object and let it load the specified video file

Define the Surfaceview component in the interface layout file, or create the Surfaceview component in the program, and add Surfaceholder listeners for the callback of Surfaceview Surfaceview

Call the MediaPlayer object's Setpisplay (Surfaceholder sh): Outputs the video image that is played to the specified Surfaceview component

Call the start (), Stop (), and Pause () methods of the MediaPlayer object to control the playback of the video

Sample code:

XML layout:

<?xml version= "1.0" encoding= "Utf-8"? ><relativelayout xmlns:android= "http://schemas.android.com/apk/res/    Android "android:orientation=" vertical "android:layout_width=" match_parent "android:layout_height=" Match_parent " ><surfaceviewandroid:id= "@+id/surfaceview" android:layout_width= "Match_parent" android:layout_height= " 360DP "/><linearlayoutandroid:orientation=" horizontal "android:layout_width=" Match_parent "Android:layout_ height= "Wrap_content" android:layout_alignparentbottom= "true" android:gravity= "Center_horizontal" >< Imagebuttonandroid:id= "@+id/play" android:layout_width= "wrap_content" android:layout_height= "Wrap_content"     android:src= "@drawable/play"/><imagebutton android:id= "@+id/pause" android:layout_width= "Wrap_content" android:layout_height= "Wrap_content" android:src= "@drawable/pause"/><imagebuttonandroid:id= "@+id/stop" Android:layout_width= "Wrap_content" android:layout_height= "wrap_content" android:src= "@drawable/stOp "/></linearlayout></relativelayout>
