Just watch the tutorials 71, 72 and 73 and it should work.

Answer 2

You need to track the coordinates of your drawable so you can compare with the touch x, y coordinates.

So basically:

// can modify to adjust speed at which drawable moves
int movementSpeed = 2;  

if (drawableX < x)
  drawableX += movementSpeed;
else if (drawableX > x)
  drawableX -= movementSpeed;

if (drawableY < y)
  drawableY += movementSpeed;
else if (drawableY > y)
  drawableY -= movementSpeed;

Then need to redraw your drawable with the updated drawableX, drawableY coordinates.
