You need to enable touches by adding this.setIsTouchEnabled(true); to the constructor of your CCLayer. Then override ccTouchesMoved, like this:
@Override
public boolean ccTouchesMoved(MotionEvent e)
{
// convert event location to CCPoint
CCPoint p = CCDirector.sharedDirector().convertToGL(e.getX(), e.getY());
// update the position of your sprite
yourSprite.setPosition(p.x, p.y);
return true;
}

\$\begingroup\$ @jubin: You could simply set the position of the Box2d body in the
ccTouchesMovedfunction. Or implement mouse-picking using the MouseJoint like in the Box2d testbed. \$\endgroup\$– bummzackCommented Aug 22, 2011 at 7:13 -
\$\begingroup\$ Thanks for the reply if i want to do this without using mouse joint can i do becoz i don't know how to use the mouse joint. I am new in game development. \$\endgroup\$– jubinCommented Aug 24, 2011 at 1:20

\$\begingroup\$ @jubin: If that stuff is too complicated for you, you might want to consider not using a physics-eninge at all and rather implement a simple game without the use of Box2d. \$\endgroup\$– bummzackCommented Aug 24, 2011 at 6:57
