tablayout横向滑动

需要添加依赖，添加后会报错，改为26.+就行

xml布局代码

<RelativeLayoutxmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:app="http://schemas.android.com/apk/res-auto"

    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    tools:context="zhanghaijiao.bawei.com.tablayout_demo.MainActivity">

 

    <!--

         app:tabGravity="center"    设置居中对齐

        app:tabIndicatorColor="@color/colorAccent" 下滑线的颜色

        app:tabMode="scrollable"  设置tabLayoout菜单的模式,,,scrollable可以横向滚动  fixed:固定

        app:tabSelectedTextColor="@color/colorPrimaryDark"  选中的时候文字的颜色

        app:tabTextColor="@color/colorPrimary"       文本默认的颜色

    -->

 

    <android.support.design.widget.TabLayout

        android:layout_width="match_parent"

        android:layout_height="50dp"

        android:id="@+id/mytab"

        app:tabGravity="center"

        app:tabIndicatorColor="@color/colorAccent"

        app:tabMode="scrollable"

        app:tabSelectedTextColor="@color/colorPrimaryDark"

        app:tabTextColor="@color/colorPrimary"></android.support.design.widget.TabLayout>

 

 

 

</RelativeLayout>




只添加选项卡

myTab.addTab(myTab.newTab().setText("新闻"));




监听事件

 //选项卡被选中的监听事件

        myTab.setOnTabSelectedListener(newTabLayout.OnTabSelectedListener() {

            @Override

            publicvoid onTabSelected(TabLayout.Tab tab) {

                Toast.makeText(MainActivity.this,tab.getText().toString(),Toast.LENGTH_SHORT).show();

 

            }

 

            @Override

            publicvoid onTabUnselected(TabLayout.Tab tab) {

 

            }

 

            @Override

            publicvoid onTabReselected(TabLayout.Tab tab) {

 

            }

        });

 

显示tablayout的页面

publicclass Fragment_04 extendsFragment{

 

    privateTabLayout myTab;

    privateViewPager view_Pager;

    List<TabModel>  myTabs=newArrayList<>();

    @Nullable

    @Override

    publicView onCreateView(LayoutInflater inflater, @NullableViewGroup container, @NullableBundle savedInstanceState) {

 

        View view = inflater.inflate(R.layout.fragment4, container, false);

        myTab = (TabLayout) view.findViewById(R.id.my_tab);

        view_Pager = (ViewPager) view. findViewById(R.id.view_pager);

        returnview;

    }

 

    @Override

    publicvoid onActivityCreated(@NullableBundle savedInstanceState) {

        super.onActivityCreated(savedInstanceState);

 

        myTabs.add(newTabModel("数据新闻","xbsjxw"));

        myTabs.add(newTabModel("快讯","txs"));

        myTabs.add(newTabModel("头条","toutiao"));

        myTabs.add(newTabModel("精编公告","news/mobile/jbgg"));

        myTabs.add(newTabModel("美股","news/mobile/mgxw"));

        myTabs.add(newTabModel("港股","news/mobile/ggxw"));

        myTabs.add(newTabModel("基金","news/mobile/jjxw"));

        myTabs.add(newTabModel("理财","news/mobile/lcxw"));

 

        //创建适配器

        view_Pager.setAdapter(newMyVpAdapter(getActivity().getSupportFragmentManager()));

 

        //将TabLayout与viewPager创建关联

        myTab.setupWithViewPager(view_Pager);

 

        //设置加载全部界面数据

        view_Pager.setOffscreenPageLimit(myTabs.size());

 

 

    }

 

    classMyVpAdapter extendsFragmentPagerAdapter {

        publicMyVpAdapter(FragmentManager fm) {

            super(fm);

        }

 

        //返回每个页面的title

        @Override

        publicCharSequence getPageTitle(intposition) {

            returnmyTabs.get(position).getName();

        }

 

        @Override

        publicFragment getItem(intposition) {

 

            //position:页面的下标

 

            Bundle b=newBundle();

            String urls = myTabs.get(position).getUrls();

            b.putString("key",urls);

            b.putString("pageIndex","1");

            v_fragment v_fragment=newv_fragment();

            v_fragment.setArguments(b);

 

 

 

            returnv_fragment;

        }

 

        //返回viewPager的加载的页面的数量

        @Override

        publicint getCount() {

            returnmyTabs.size();

        }

    }

}




tablayout显示对应界面的fragment：使用的xlistview列表，根据不同标题的不同url请求数据，接收到值进行的url拼接

publicclass v_fragment extendsFragment {

 

    privateXListView xlist_view;

 

    private String urlpart="http://mnews.gw.com.cn/wap/data/news/";

    privateString key_url;

    privateString Y="/page_";

    privateint pageIndex=1;//第1页的数据

    privateString j=".json";

    privateString url;

    privateList<UserBean_1.DataBean> data=newArrayList<>();

    privateMyAdapter_01 adapter;

    privateint operType=1;

    privateBundle bundle;

 

    @Nullable

    @Override

    publicView onCreateView(LayoutInflater inflater, @NullableViewGroup container, @NullableBundle savedInstanceState) {

        View view = inflater.inflate(R.layout.v_layout, container, false);

        xlist_view = view.findViewById(R.id.xlist_view);

        bundle = getArguments();

        if(bundle !=null){

              key_url = bundle.getString("key");

             url=urlpart+key_url+Y+pageIndex+j;

        }

        returnview;

    }

 

    @Override

    publicvoid onActivityCreated(@NullableBundle savedInstanceState) {

        super.onActivityCreated(savedInstanceState);

 

       //对xlistview进行设置

        xlist_view.setPullLoadEnable(true);//上拉加载更多

        //设置接口

        xlist_view.setXListViewListener(newXListView.IXListViewListener() {
