Android achartengine issue

Have a question to ask you about, I was in a tabhost which used achartengine, but I do not know why the set setClickEnabled (true) after not slide and zoom , and this is how you ask ? renderer.setPanEnabled (true, true); renderer.setZoomEnabled (true, true); are set
------ Solution ----------- ---------------------------------
this problem too abstract , achartengine I used to use just fine I do not know is what you tabhost controls whether the event is that it intercepted
------ reference ------------------------- --------------
have a good job , also thank you .
