    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent" 
       android:layout_height="fill_parent" > 
     <VideoView android:id="@+id/myvideoview" 
         android:layout_width="fill_parent" 
         android:layout_alignParentRight="true"
          android:layout_alignParentLeft="true" 
         android:layout_alignParentTop="true"
          android:layout_alignParentBottom="true"

Answer 1

Get the height and width of the original video.
Get the height and width of the screen(in current orientation).

float ratioWidth = screenWidth / videoWidth;
float ratioHeight = screenHeight / videoHeight;
float fullWidth;
float fullHeight;
if (ratioWidth < ratioHeight ) {  
    fullWidth = videoWidth * ratioWidth;
    fullHeight = videoHeight * ratioWidth;
} else {
    fullWidth = videoWidth * ratioHeight;
    fullHeight = videoHeight * ratioHeight;
}

Set fullWidth and fullHeight to the VideoView.
