视频播放控件SurfaceView与VideoView 既然是播放一段视频，那么不可避免的要涉及到一些开始、暂停、停止等操作， VideoView也为开发人员提供了对应的方法，这里简单介绍一些常用的： //设置数据源 mediaPlayer.setDataSource(context, Uri.parse(uri) ); //准备 mediaPlayer.prepareAsync(); //绑定surfaceview mediaPla 阅读详情

VideoView

概述：
这个类其实也是继承了SurfaceView 类，集成度高，开发难度小，只是灵活性差。

通过VideoView播放视频的步骤：

1、在界面布局文件中定义VideoView组件，或在程序中创建VideoView组件

2、调用VideoView的如下两个方法来加载指定的视频

setVidePath(String path):加载path文件代表的视频

setVideoURI(Uri uri)：加载uri所对应的视频

VideoView的使用：
1.1系统方法

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.android_playvideo.VideoActivity">

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

</LinearLayout>

package com.example.android_playvideo;

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

public class VideoActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_video);
         VideoView videoView= (VideoView) findViewById(R.id.vv_mian_Video);
        videoView.setVideoURI(Uri.parse("file://mnt/sdcard/dcim/camera/VID20170211215528.mp4"));
        MediaController mediaController=new MediaController(this);
        mediaController.setMediaPlayer(videoView);
        videoView.setMediaController(mediaController);
    }

}
