判断拼接url

1.在viewpager适配器中传值

vp.setAdapter(new FragmentPagerAdapter(getChildFragmentManager()) {    @Override    public CharSequence getPageTitle(int position) {        return titles.get(position);    }    @Override    public Fragment getItem(int position) {        FFF1 fff1 = new FFF1();        Bundle bundle = new Bundle();        bundle.putString("ming",titles.get(position));        fff1.setArguments(bundle);        return fff1;    }    @Override    public int getCount() {        return titles.size();    }});tab.setupWithViewPager(vp);vp.setOffscreenPageLimit(titles.size());

2.接收并判断然后拼接

String name = getArguments().getString("ming","");if (name!=null){    String getname = getname(name);    getdata.getdatafromnet(getActivity(), "http://mnews.gw.com.cn/wap/data/news/"+getname+"/page_1.json", new Callback() {        @Override        public void getsjson(String json) {            try {                Log.d("TAG","++++++++++++++++++"+json);                Gson gson = new Gson();                Type type = new TypeToken<List<Bean>>() {}.getType();                List<Bean> data = gson.fromJson(json, type);                for (Bean b:data) {                    data1.addAll(b.getData());                }                lv.setAdapter(new Listadapter(getActivity(),data1));            } catch (Exception e) {                e.printStackTrace();            }        }    });}
判断
private String getname(String name){    String str="";    if (name.equals("数据新闻")){         str="xbsjxw";    }else if (name.equals("快讯")){          str="txs";    }else if (name.equals("头条")){         str="toutiao";    }else if (name.equals("精编公告")){         str="news/mobile/jbgg";    }else if (name.equals("美股")){         str="news/mobile/mgxw";    }else if (name.equals("港股")){         str="news/mobile/ggxw";    }else if (name.equals("基金")){         str="news/mobile/jjxw";    }else if (name.equals("理财")){          str="news/mobile/lcxw";    }    return str;}
