<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"

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

</RelativeLayout>

this is my .java file

package com.example.tryit;

import android.net.Uri;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.widget.VideoView;

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    VideoView vv = (VideoView) findViewById(R.id.vidvew);
    String fileName = "android.resource://" + getPackageName() + "/" +R.raw.cs;
    vv.setVideoURI(Uri.parse(fileName));
    vv.start();


}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

}

Check the encoding of the video properly. Android allows only certain types of file types to be played in the app. Please see the link below for more information - http://developer.android.com/guide/appendix/media-formats.html
