019_02视频播放之VideoView

　　Android系统提供的VideoView视频播放组件非常方便。只需要三步：

1，在界面布局文件中定义VideoView组件

2，调用VideoView的setVideoPath(String path)或者setVideoURI(Uri uri)方法加载指定视频

3，调用VideoView的start(),stop(),pause()方法来操作视频

　　MediaController还提供了快进，暂停，后退，以及播放进度条，这样就不需要开发者自己去敲代码了。

 1 package com.example.day19_02videoplayer2;
 2 
 3 import android.app.Activity;
 4 import android.os.Bundle;
 5 import android.os.Environment;
 6 import android.widget.MediaController;
 7 import android.widget.VideoView;
 8 
 9 public class MainActivity extends Activity {
10 
11     @Override
12     protected void onCreate(Bundle savedInstanceState) {
13         super.onCreate(savedInstanceState);
14         setContentView(R.layout.activity_main);
15         
16         String    path = Environment.getExternalStorageDirectory().getAbsolutePath()+"/sirendingzhi.mp4";
17 
18         VideoView video = (VideoView) findViewById(R.id.vv_video);
19         video.setVideoPath(path);        
20         video.setMediaController(new MediaController(this));
21         video.start();    
22     } 
23 }

 

 1 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 2     xmlns:tools="http://schemas.android.com/tools"
 3     android:layout_width="match_parent"
 4     android:layout_height="match_parent"
 5     android:paddingBottom="@dimen/activity_vertical_margin"
 6     android:paddingLeft="@dimen/activity_horizontal_margin"
 7     android:paddingRight="@dimen/activity_horizontal_margin"
 8     android:paddingTop="@dimen/activity_vertical_margin"
 9     tools:context="com.example.day19_02videoplayer2.MainActivity" >
10  
11     <VideoView 
12         android:layout_height="fill_parent" 
13         android:layout_width="fill_parent"
14         android:id="@+id/vv_video"
15         />
16 
17 </RelativeLayout>

 

当点击播放画面时，屏幕底端就会弹出MediaController
