通过VideoView+MediaController实现视频播放

这是本人继上一篇的视频播放的另一种方式，使用VideoView+MediaController实现

清单文件：

<!-- 读取内存卡的权限 -->
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" android:id="@+id/activity_main"
    android:layout_width="match_parent" android:layout_height="match_parent"
    tools:context="com.example.g150825_playvideo.MainActivity">

    <VideoView
        android:layout_width="200dp"
        android:layout_height="200dp"
        android:id="@+id/main_vv_first"
        />
</LinearLayout>

MainActivity.java

package com.example.g150825_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 MainActivity extends AppCompatActivity {

    private VideoView main_vv_first;

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

        main_vv_first = (VideoView) findViewById(R.id.main_vv_first);

        //设置视屏的来源
        main_vv_first.setVideoURI(Uri.parse("file://mnt/sdcard/music11/videoplayer.mp4"));

        //实例化媒体控制器
        MediaController mediaController=new MediaController(this);
        //互设
        mediaController.setMediaPlayer(main_vv_first);
        main_vv_first.setMediaController(mediaController);


    }
}

加上上一篇的内容都是比较简单的视频播放方式
