本文介绍了在Android应用中添加外部存储读写权限，布局实现VideoView播放视频文件，并详细展示了视频路径配置和多媒体控制器集成的过程。

添加权限：

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

布局：

/VedioViewTest/res/layout/activity_main.xml

<pre name="code" class="html"><LinearLayout 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"
     >

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

/VedioViewTest/src/com/lxm/vedioviewtest/MainActivity.java

package com.lxm.vedioviewtest;


import java.io.File;


import android.app.Activity;
import android.os.Bundle;
import android.os.Environment;
import android.view.Menu;
import android.widget.MediaController;
import android.widget.VideoView;


public class MainActivity extends Activity {
	VideoView videoView;
	MediaController mController;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		videoView = (VideoView) findViewById(R.id.video);
		mController = new MediaController(this);
		//记得修改路径
		String mp4Path = Environment.getExternalStorageDirectory()+"/mv";
		File video = new File(mp4Path+"/Roar.mp4");
		if(video.exists()){
			videoView.setVideoPath(video.getAbsolutePath()); 
			videoView.setMediaController(mController);  
			// 设置mController与videoView建立关联
			mController.setMediaPlayer(videoView); 
			videoView.requestFocus();
		}
	}


	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.main, menu);
		return true;
	}


}
