Question

I have this project in which I have a bitmap bigger than the screen size. I want to resize it to fit the screen exactly. I have no titlebar, and I am in fullscreen mode. This is my non-working code:

public class ScopView extends View
{
    private Scop thescop;

    public ScopView(Context context, Scop newscop)
    {
        super(context);
        this.thescop = newscop;
    }

    @Override
    public void onDraw(Canvas canvas)
    {
        Bitmap scopeBitmap;
        BitmapFactory.Options bfOptions = new BitmapFactory.Options();
        bfOptions.inDither = false;
        bfOptions.inPurgeable = true;
        bfOptions.inInputShareable = true;
        bfOptions.inTempStorage = new byte[32 * 1024];

        scopeBitmap = BitmapFactory.decodeResource(getResources(),R.drawable.scope, bfOptions);
        scopeBitmap.createScaledBitmap(scopeBitmap, SniperActivity.Width, SniperActivity.Height, false);
        canvas.drawBitmap(scopeBitmap, SniperActivity.scopx, SniperActivity.scopy, null);
    }
}

While in here the createScaledBitmap method, I am using itself as the source, and some variables from an activity used to retrieve the window height and width from screen preferences.

You can use the below code to resize the bitmap.

int h = 320; // Height in pixels
int w = 480; // Width in pixels    
Bitmap scaled = Bitmap.createScaledBitmap(largeBitmap, h, w, true);
