Negative X offset for SurfaceView

Hi,

I'm looking for a way to create a SurfaceView which is larger than the native resolution of the device's screen.
E.g. my screen is 480x320 and I want to create a SurfaceView of 533x320.

I need the surface tio be this size because I want to play video with a res of 800x480 and have it scaled down to 533x320 pixels. So my plan is to have it play in a 533x320 SurfaceView and then have this view shifted in x by 26 pixels to the left which will centre the movie on the screen.

I've tried setting the SurfaceView layout_width="533px" in my xml file but it doesn't work. The surface still only takes up 480x320 pixels as if the width of 533 is clipped to 480 somehow.

Any thoughts?

Thanks,
Phil.

Hi,

I worked out a solution to this. I needed to use an AbsoluteLayout.

E,g, in xml :-

Syntax: [ Download ] [ Hide ]

Using xml Syntax Highlighting

<AbsoluteLayout ...
 
    <SurfaceView android:id="@+id/surface"
 
                 android:layout_width="1200px"
 
                 android:layout_height="480px"
 
                 android:layout_x="-400px"
 
                 android:layout_y="0px">
 
    </SurfaceView>
 
</AbsoluteLayout>
Parsed in 0.001 seconds,  using GeSHi 1.0.8.4

Or in Java :-

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

    int w = 1200;
 
    int h = 480;
 
    int x = -400; 
 
    int y = 0;
 
    SurfaceView surface = (SurfaceView)findViewById(R.id.surface);
 
    AbsoluteLayout.LayoutParams p = new AbsoluteLayout.LayoutParams(w, h, x, y);   
 
    surface.setLayoutParams(p);
