无线自动轮播，获取网络上的图片+scrollView+listView 联动

结合pulltorefresh那篇：

效果：

布局：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:background="#f890"    android:orientation="vertical"    android:layout_height="match_parent"><com.handmark.pulltorefresh.library.PullToRefreshScrollView    xmlns:ptr="http://schemas.android.com/apk/res-auto"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:id="@+id/refresh_scroll_view"    ptr:ptrDrawable="@drawable/default_ptr_flip"    ptr:ptrAnimationStyle="flip"    ptr:ptrHeaderBackground="#383838"    ptr:ptrHeaderTextColor="#FFFFFF"    >    <LinearLayout        android:layout_width="match_parent"        android:layout_height="match_parent"        android:orientation="vertical">        <android.support.v4.view.ViewPager            android:id="@+id/scroll_vp"            android:layout_width="match_parent"            android:layout_height="200dp">        </android.support.v4.view.ViewPager>        <com.example.day16_pulltorefresh.view.MyListView            android:id="@+id/scroll_lv"            android:layout_width="match_parent"            android:layout_height="match_parent">        </com.example.day16_pulltorefresh.view.MyListView>    </LinearLayout></com.handmark.pulltorefresh.library.PullToRefreshScrollView></LinearLayout>

代码：

public class FragmentScroll extends Fragment{List<DataDataBean.ResultsBean> list=new ArrayList<>();    private PullToRefreshScrollView refreshScrollView;    private ViewPager viewPager;    private ListView listView;    private int num_page=1;    private ListAdapter adapter;    private ILoadingLayout startLabels;    private List<String> imglist;
Handler handler=new Handler(){    @Override    public void handleMessage(Message msg) {        if (msg.what==0){            viewPager.setCurrentItem(viewPager.getCurrentItem()+1);            handler.sendEmptyMessageDelayed(0,2000);        }    }};    @Nullable    @Override    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {        View view = inflater.inflate(R.layout.fragment_scroll, container, false);        refreshScrollView = (PullToRefreshScrollView) view.findViewById(R.id.refresh_scroll_view);        viewPager = (ViewPager) view.findViewById(R.id.scroll_vp);        listView = (ListView) view.findViewById(R.id.scroll_lv);        return view;    }    @Override    public void onActivityCreated(@Nullable Bundle savedInstanceState) {        super.onActivityCreated(savedInstanceState);//失去焦点        listView.setFocusable(false);//轮播        String lbpath="http://v3.wufazhuce.com:8000/api/reading/index/?version=3.5.0&platform=android";        NetConnection.getconnection(getActivity(), lbpath, new CallJsonBack() {            @Override            public void getcallBack(String json) {                imglist = new ArrayList<String>();                Gson gson=new Gson();                GridBean gridBean = gson.fromJson(json, GridBean.class);                List<GridBean.DataBean.EssayBean> essay = gridBean.getData().getEssay();                for (GridBean.DataBean.EssayBean essayBean: essay) {                    imglist.add(essayBean.getAuthor().get(0).getWeb_url());                }                VpAdapter vpAdapter=new VpAdapter(imglist,getActivity());                viewPager.setAdapter(vpAdapter);                viewPager.setCurrentItem(imglist.size()*100000);                handler.sendEmptyMessageDelayed(0,2000);            }        });//listView展示        getconn();        startLabels = refreshScrollView.getLoadingLayoutProxy(true, false);        startLabels.setPullLabel("下拉刷新");        startLabels.setRefreshingLabel("正在拉");        startLabels.setReleaseLabel("放开刷新");        ILoadingLayout endLabels = refreshScrollView.getLoadingLayoutProxy(false, true);        endLabels.setPullLabel("上拉刷新");        endLabels.setRefreshingLabel("正在载入...");        endLabels.setReleaseLabel("放开刷新...");        refreshScrollView.setOnRefreshListener(new PullToRefreshBase.OnRefreshListener2<ScrollView>() {            @Override            public void onPullDownToRefresh(PullToRefreshBase<ScrollView> refreshView) {                String path="http://gank.io/api/data/Android/10/1";                NetConnection.getconnection(getActivity(), path, new CallJsonBack() {                    @Override                    public void getcallBack(String json) {                        Gson gson=new Gson();                        DataDataBean dataDataBean = gson.fromJson(json, DataDataBean.class);                        Log.i("-----sc2",dataDataBean.toString());                        list.addAll(0,dataDataBean.getResults());                        setAdapter();                        //停止刷新                        refreshScrollView.onRefreshComplete();                        startLabels.setLastUpdatedLabel("上次更新时间:"+new SimpleDateFormat("HH:mm").format(new Date(System.currentTimeMillis())));                    }                });            }            @Override            public void onPullUpToRefresh(PullToRefreshBase<ScrollView> refreshView) {                num_page++;                getconn();            }        });    }    private void getconn() {        String path="http://gank.io/api/data/Android/10/"+num_page;        NetConnection.getconnection(getActivity(), path, new CallJsonBack() {            @Override            public void getcallBack(String json) {                Gson gson=new Gson();                DataDataBean dataDataBean = gson.fromJson(json, DataDataBean.class);                Log.i("----s1",dataDataBean.toString());                List<DataDataBean.ResultsBean> results = dataDataBean.getResults();                Log.i("-----s1",results.toString());                list.addAll(results);                setAdapter();                //停止刷新                refreshScrollView.onRefreshComplete();            }        });    }    private void setAdapter() {        if (adapter==null){            adapter = new ListAdapter(list,getActivity());            listView.setAdapter(adapter);        }else{            adapter.notifyDataSetChanged();        }    }}
轮播的适配器
public class VpAdapter extends PagerAdapter{    List<String> imglist;    Context con;    public VpAdapter(List<String> imglist, Context con) {        this.imglist = imglist;        this.con = con;    }    @Override    public int getCount() {        return Integer.MAX_VALUE;    }    @Override    public boolean isViewFromObject(View view, Object object) {        return view==object;    }    @Override    public Object instantiateItem(ViewGroup container, int position) {        ImageView imageView=new ImageView(con);        imageView.setScaleType(ImageView.ScaleType.FIT_XY);        ImageLoader.getInstance().displayImage(imglist.get(position%imglist.size()),imageView, ImageUtil.getoption());        container.addView(imageView);        return imageView;    }    @Override    public void destroyItem(ViewGroup container, int position, Object object) {        container.removeView((View) object);    }}
ScrollView和ListView有冲突所以
自定义个类继承Listview 
public class MyListView extends ListView{    public MyListView(Context context) {        super(context);    }    public MyListView(Context context, AttributeSet attrs) {        super(context, attrs);    }    public MyListView(Context context, AttributeSet attrs, int defStyleAttr) {        super(context, attrs, defStyleAttr);    }    @Override    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {        int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);//添加这句话        super.onMeasure(widthMeasureSpec, expandSpec);
  //名字返回    }}
并且复制自定义ListView的全路径，复制到布局listView上（参考布局）
