This is my code

        // Tell the user to provide a media file URL/path.
        Toast.makeText(
                VideoPlay.this,
                "Please edit VideoViewDemo Activity, and set path"

  android:id="@+id/video"
   android:layout_width="320px"
   android:layout_height="240px">
   </VideoView>
   </FrameLayout>

解决方案

Check the following code which is there in the Android SDK demo

package com.example.android.apis.media;

import com.example.android.apis.R;

import android.app.Activity;

import android.os.Bundle;

import android.widget.MediaController;

import android.widget.Toast;

import android.widget.VideoView;

public class VideoViewDemo extends Activity {

    /**
     * TODO: Set the path variable to a streaming video URL or a local media
     * file path.
     */
    private String path = "";
    private VideoView mVideoView;

    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.videoview);
        mVideoView = (VideoView) findViewById(R.id.surface_view);

        if (path == "") {
            // Tell the user to provide a media file URL/path.
            Toast.makeText(
                    VideoViewDemo.this,
                    "Please edit VideoViewDemo Activity, and set path"
                            + " variable to your media file URL/path",
                    Toast.LENGTH_LONG).show();

        } else {

            /*
             * Alternatively,for streaming media you can use
             * mVideoView.setVideoURI(Uri.parse(URLstring));
             */
            mVideoView.setVideoPath(path);
            mVideoView.setMediaController(new MediaController(this));
            mVideoView.requestFocus();

        }
    }
}

videoview.xml

<VideoView 
    android:id="@+id/surface_view" 
    android:layout_width="320px"
    android:layout_height="240px"
/>
