一个Activity或者是Fragment中三个Fragment进行切换

lvCommunity.itemClick(new SNAdapterOnItemClickListener() {

           public void onItemClick(SNAdapterViewInject snAdapterViewInject) {

                if (snAdapterViewInject.getData(CommunitySplate.class) instanceof CommunitySplate) {

                   CommunitySplate splate = snAdapterViewInject.getData(CommunitySplate.class);

                   Intent intent=new Intent(getBaseActivity(),CommunityForumsTopicsActivity.class);

                   intent.putExtra("topics_id",splate.getId()+"");

                    intent.putExtra("topics_name",splate.getName());

                    getBaseActivity().startActivityAnimate(intent);

               } else if (snAdapterViewInject.getData(CommuniityTopics.class) instanceof CommuniityTopics) {

                    CommuniityTopics topics = snAdapterViewInject.getData(CommuniityTopics.class);

                    getBaseActivity().startActivityAnimate(CommunityTopicActivity.class);

               } else if (snAdapterViewInject.getData(CommunityRemonmend.class) instanceof CommunityRemonmend) {

                   CommunityRemonmend remonmend = snAdapterViewInject.getData(CommunityRemonmend.class);

                    getBaseActivity().startActivityAnimate(CommunityTopicActivity.class);

               }

           }

        });

这里主要使用的是instanceOf关键字，也就是某个对象与某个类的相近度。
