如何在点击“显示视频”按钮后播放视频？

Question

有人能告诉我什么是我应该添加到我当前的代码播放视频的具体代码？

public class ViewVideo extends Activity { 
     private String filename; 
     @Override 
     public void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 

      Bundle extras = getIntent().getExtras(); 
      filename = extras.getString("videoPath"); 

      VideoView viewVideo = new VideoView(this); 
      setContentView(viewVideo); 
      viewVideo.setVideoPath(filename); 
      viewVideo.setMediaController(new MediaController(this)); 
      viewVideo.requestFocus(); 
      viewVideo.start(); 

     } 
}

有不止一种方式在Android的播放媒体文件..

试试这个：

public void videoPlayer(String path, String fileName, boolean autoplay){ 

    getWindow().setFormat(PixelFormat.TRANSLUCENT); 

     VideoView videoHolder = new VideoView(this); 

     videoHolder.setMediaController(new MediaController(this)); 

     videoHolder.setVideoURI(Uri.parse(path+"/"+fileName)); 

     videoHolder.requestFocus(); 


     if(autoplay){ 

       videoHolder.start(); 

     } 
} 

我希望这有助于..

试试这个.. 。

public void videoPlayer(String path, String fileName, boolean autoplay){ 
    //get current window information, and set format, set it up differently, if you need some special effects 
    getWindow().setFormat(PixelFormat.TRANSLUCENT); 
    //the VideoView will hold the video 
    VideoView videoHolder = new VideoView(this); 
    //MediaController is the ui control howering above the video (just like in the default youtube player). 
    videoHolder.setMediaController(new MediaController(this)); 
    //assing a video file to the video holder 
    videoHolder.setVideoURI(Uri.parse(path+"/"+fileName)); 
    //get focus, before playing the video. 
    videoHolder.requestFocus(); 
    if(autoplay){ 
     videoHolder.start(); 
    } 

    } 

调用此方法按钮点击通过传递所需的参数（视频文件路径，文件名，自动播放）。

希望这有助于你..

    Button play,stop,sd; 
    MediaPlayer mp; 
    String path; 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main);

     stop=(Button)findViewById(R.id.stop); 
     sd=(Button)findViewById(R.id.sd); 
     play.setOnClickListener(this); 
     stop.setOnClickListener(this); 
     sd.setOnClickListener(this); 
     //mp=MediaPlayer.create(this, R.raw.sample); 
    } 
    @Override 
    public void onClick(View v) { 
     // TODO Auto-generated method stub 
     if(v==play) 
     { 
      if(mp.isPlaying()==false && mp!=null) 
      { 

         mp.start();

     if(v==sd) 
     { 
      path="/sdcard/sample.mp4"; 
      try{ 
      mp=new MediaPlayer(); 
      mp.setDataSource(path); 
      mp.prepare(); 
      mp.start(); 
      } 
      catch(Exception e) 
      { 
       Toast.makeText(this,e.toString(),Toast.LENGTH_LONG) 
       .show(); 
      }
