Is there a way to put the class that made the character move with the bitmap and thread into one view?

class CharacterView extends View {
    int width, height; // width and height of screen
    int x, y; // the character's current coordinates
    int dx, dy; // the direction and distance the character will travel
    int cw, ch; // width and height of character
    int counter; // loop counter
    Bitmap character[] = new Bitmap[2]; // character's bitmap image
    LinearLayout character_field = (LinearLayout)findViewById(R.id.character_field);


    public CharacterView(Context context) {
        super(context);

        Display display = ((WindowManager) context.getSystemService(Context.WINDOW_SERVICE))
                .getDefaultDisplay();
        width = character_field.getWidth(); // width of screen
        height = character_field.getHeight(); // width of screen
        x = 100; // the current x position of the character
        y = 100; // the current y position of the character
        dx = 2; // the distance the character moves to the x-axis
        dy = 3; // the distance the character moves to the y-axis

        // Read the character's bitmap
        character[0] = BitmapFactory.decodeResource(getResources(), R.drawable.tmp1);
        character[1] = BitmapFactory.decodeResource(getResources(), R.drawable.tmp2);

        cw = character[0].getWidth() / 2; // width of character/2
        ch = character[0].getHeight() / 2; // height of character/2

        mHandler.sendEmptyMessageDelayed(0, 10);
    }

    //-----------------------------------
    //       The part where you draw the picture
    //-----------------------------------
    public void onDraw(Canvas canvas) {
        x + = dx; // Move horizontally
        y + = dy; // Move longitudinally

        If (x < cw || x > width - cw) dx = -dx; // Walls on the left and right are reversed
        If (y < ch || y > height - ch) dy = -dy; // Change direction if ceiling or floor

        counter++;
        int n = counter % 20 / 10;
        canvas.drawBitmap(character[n], x - cw, y - ch, null);
    } // End of Draw

    //------------------------------------
    //      //      Timer Handler
    //------------------------------------
    Handler mHandler = newHandler() { // Handler to use as timer
        public void handleMessage(Message msg) {
            validate(); // onDraw() rerun
            mHandler.sendEmptyMessageDelayed(0,10); // Run every 10/1000 seconds
        }
    }; }; // Handler
} // GameView End
