如何在啓動Android應用程序時添加視頻文件

Question

我想在啓動Android應用程序時播放視頻文件。我試過了，但它不能正常工作。我收到一條錯誤消息，它告訴我們視頻無法播放。我已將我的視頻（.mp4擴展名）保存在原始文件夾中。我已經設置了以下路徑：

path = "android.resource://com.easy.video/" + R.raw.myvideo; 

這是我的java文件。

package com.easy.video; 

import android.media.MediaPlayer; 
import android.media.MediaPlayer.OnCompletionListener; 
import android.os.Bundle; 
import android.app.Activity; 
import android.content.Intent; 
import android.view.Menu; 
import android.widget.Toast; 
import android.widget.VideoView; 

@SuppressWarnings("unused") 
public class MainActivity extends Activity { 

    private VideoView videoView; 
    String extStorageDirectory; 
    protected static final int PLAY = 0x101; 
    protected static final int STOP = 0x102; 
    protected static final int PAUSE = 0x103; 
    int State; 
    private String current; 

    private String path; 
    private VideoView mVideoView; 

    @Override 
    public void onCreate(Bundle icicle) { 
     super.onCreate(icicle); 
     setContentView(R.layout.activity_main); 
     path = "android.resource://com.easy.video/" + R.raw.myvideo; 
     mVideoView = (VideoView) findViewById(R.id.video); 
     if (path == null || path.length() == 0) { 
      Toast.makeText(MainActivity.this, "File URL/path is empty", 
        Toast.LENGTH_LONG).show(); 

     } else { 
      // If the path has not changed, just start the media player 
      if (path.equals(current) && mVideoView != null) { 
       mVideoView.start(); 
       mVideoView.requestFocus(); 
       return; 
      } 
      current = path; 
      mVideoView.setVideoPath(path); 
      mVideoView.start(); 
      mVideoView.requestFocus(); 
     } 
     mVideoView.setOnCompletionListener(new OnCompletionListener() { 
      public void onCompletion(MediaPlayer arg0) { 

       Intent in = new Intent(MainActivity.this, NextActivity.class); 
       startActivity(in); 
       finish(); 
      } 
     }); 
    } 

} 

其實我不確定它是否正確。 如果有人能夠如此友好地解釋如何做到這一點，我將不勝感激。

使用Raw文件資源ID時，請使用Uri.parse（）和mVideoView.setVideoURI（Uri.parse（path））;
