java部分代码：

package com.example.vedioplay;
    
    import android.net.Uri;
    import android.os.Bundle;
    import android.support.annotation.Nullable;
    import android.support.v7.app.AppCompatActivity;
    import android.widget.MediaController;
    import android.widget.VideoView;
    
    /**
     * Created by Administrator on 2017/7/21.
     */
    
    public class VideoActivity extends AppCompatActivity {
    
        private VideoView vv;
    
        @Override
        protected void onCreate(@Nullable Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_video);
            vv = (VideoView) findViewById(R.id.vv_video);
            vv.setVideoURI(Uri.parse("file://mnt/sdcard/dcim/camera/VID_20170715_140439.mp4"));
            MediaController mediaController=new MediaController(this);
            mediaController.setMediaPlayer(vv);
            vv.setMediaController(mediaController);
        }
    }

xml部分代码：

<?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="vertical" android:layout_width="match_parent"
        android:layout_height="match_parent">
    
            <VideoView
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:id="@+id/vv_video"
                />
    
    </LinearLayout>

还有不能忘记的权限授予：

<?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.example.vedioplay">
    
        
        <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
        <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
        <uses-permission android:name="android.permission.CAMERA" />
        <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS"></uses-permission>
    
        <application android:allowBackup="true" android:icon="@mipmap/ic_launcher"
            android:label="@string/app_name" android:roundIcon="@mipmap/ic_launcher_round"
            android:supportsRtl="true" android:theme="@style/AppTheme">
            <activity android:name=".MainActivity">
                <intent-filter>
                    <action android:name="android.intent.action.MAIN" />
    
                    <category android:name="android.intent.category.LAUNCHER" />
                </intent-filter>
            </activity>
        </application>
    
    </manifest>
