Android中利用VideoView播放网络上视频的基础用法

Demo:



代码:

主活动为LocalVideoActivity

package com.example.playvideotest;

import android.media.MediaPlayer;
import android.net.Uri;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.MediaController;
import android.widget.Toast;
import android.widget.VideoView;

public class LocalVideoActivity extends AppCompatActivity {

private VideoView videoview ;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

//本地的视频 需要在手机SD卡根目录添加一个Demo.mp4 视频
// String videoUrl1 = Environment.getExternalStorageDirectory().getPath()+"/Demo.mp4" ;

//网络视频

videoview = (VideoView)this.findViewById(R.id.video_view );

//设置视频控制器
videoview.setMediaController(new MediaController(this));

//播放完成回调
videoview.setOnCompletionListener( new MyPlayerOnCompletionListener());

//设置视频路径
//videoView.setVideoURI(uri);
videoview.setVideoPath("http://172.28.6.100/item/video/Y02_01.mp4");

//开始播放视频
videoview.start();
}

class MyPlayerOnCompletionListener implements MediaPlayer.OnCompletionListener {

@Override
public void onCompletion(MediaPlayer mp) {
Toast.makeText( LocalVideoActivity.this, "播放完成了", Toast.LENGTH_SHORT).show();
}
}
}注:上述Demo中 .mp4格式的视频是在PC服务器端存放,自己需要换成自己可访问的url
主布局activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.example.playvideotest.LocalVideoActivity">

<RelativeLayout
android:layout_width="match_parent"
android:layout_height="200dp">

<VideoView
android:id="@+id/video_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>

</RelativeLayout>

</RelativeLayout>
最后由于需要访问网络,Androidmanifest.xml中加入访问权限的声明
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
