        int imageHeight = image.getHeight();
        if ( imageHeight > maxHeight )
        imageHeight = maxHeight;

        if ( imageWidth > maxWidth ) {
        imageWidth = maxWidth;
        imageHeight = (imageWidth*image.getHeight()) / image.getWidth();

Display display = ((WindowManager) getSystemService(WINDOW_SERVICE)).getDefaultDisplay();
int screenWidth = display.getWidth();
int screenHeight = display.getHeight();
