您好,我需要显示SD卡中的视频。我将我的视频保存在SD卡中并尝试使用以下代码。但视频没有显示....请帮助我出错的地方......

我的代码:

package com.videoapp;

import android.app.Activity;
import android.os.Bundle;
import android.widget.MediaController;
import android.widget.VideoView;

public class NewvideoappActivity extends Activity
{
    private VideoView vView;

    @Override
    public void onCreate(Bundle savedInstanceState) 
    { 
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        vView = (VideoView)findViewById(R.id.myvideoview);
        vView.requestFocus();
        vView.setVideoPath("/sdcard/watch.3gp");
      vView.setMediaController(new MediaController(this));
        vView.start();
    }
}

main.xml中

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:orientation="vertical"
   android:layout_width="fill_parent"
   android:layout_height="fill_parent"
   >
<TextView
   android:layout_width="fill_parent"
   android:layout_height="wrap_content"
   android:text="@string/hello"
   />
<LinearLayout
   android:orientation="vertical"
   android:layout_width="fill_parent"
   android:layout_height="wrap_content">
<VideoView
   android:id="@+id/myvideoview"
   android:layout_width="fill_parent"
   android:layout_height="wrap_content" />
</LinearLayout>
</LinearLayout>

vv = (VideoView) findViewById(R.id.videoView1);
vv.setVideoURI(Uri.parse("/sdcard/myvideo.3gp"));
vv.start();
