Modify focal length Copy Code code as follows: public void Setzoom () { if (missupportzoom) { Try { Parameters params = Mcamera.getparameter

returns the value: if for the control that does not have child, if want to return to touch processing best True. This is often used in game development, if the control has children, do not do so, or the child will not listen to touch events.
