在Android中播放視頻

Question

Im在android im中實現視頻播放完全是新的android，這是我迄今收集的代碼位。

根據它應該播放視頻的邏輯。不知道我做錯了什麼。

package com.themetanoia.readfilefromsdc; 

import java.io.File; 

import android.app.ListActivity; 
import android.content.Context; 
import android.content.Intent; 
import android.graphics.PixelFormat; 
import android.net.Uri; 
import android.os.Bundle; 
import android.os.Environment; 
import android.util.Log; 
import android.view.View; 
import android.widget.AdapterView; 
import android.widget.ArrayAdapter; 
import android.widget.ListView; 
import android.widget.MediaController; 
import android.widget.TextView; 
import android.widget.Toast; 
import android.widget.VideoView; 
import android.widget.AdapterView.OnItemClickListener; 

public class ReadFileFromSDCActivity extends ListActivity { 
    /** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

     //Get the file path for external storage 
     String a = Environment.getExternalStorageDirectory().getAbsolutePath(); 
     final String finalPath = a+"/Videos"; 
     //Define new file function 
     File f=new File(finalPath); 

     if(f.isDirectory()){    
     //Define arrayadapter 
      setListAdapter(new ArrayAdapter<String>(this, R.layout.listview,files)); 
      //Define listview 
      ListView listview = getListView(); 
      listview.setTextFilterEnabled(true); 

      //Onclick list item event 
      listview.setOnItemClickListener(new OnItemClickListener() { 

     @Override 
     public void onItemClick(AdapterView<?> parent, View view, 
         int position, long id) { 


        //get selected items 
        String selectedValue = (String) getListAdapter().getItem(position);   
        Uri uri = Uri.parse(finalPath); 

        MediaController mediaController = new MediaController(getBaseContext()); 
        mediaController.setAnchorView(mVideoView); 

        Uri video = Uri.parse(finalPath+"/"+selectedValue); 
        mVideoView.setMediaController(mediaController); 
        mVideoView.setVideoURI(video); 
        mVideoView.start(); 

       } 


      });    

     } 



} 


}

<VideoView 
    android:id="@+id/videoView1" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    /> 


VideoView vv = (VideoView) findViewById(R.id.videoView1); 
uri = "your video uri"; 
vv.setVideoURI(Uri.parse(uri)); 
vv.start(); 

vv.setOnCompletionListener(new OnCompletionListener() { 
    @Override 
    public void onCompletion(MediaPlayer mp) { 
      finish(); 
    } 
});
