PullToRefreshScrollView 整体刷新的使用

1.布局     导入library,建立依赖，只能有一个子控件，所以建立linearlayout

<com.handmark.pulltorefresh.library.PullToRefreshScrollView
    android:id="@+id/sw"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <android.support.v4.view.ViewPager
            android:id="@+id/vp"
            android:layout_width="match_parent"
            android:layout_height="150dp">

        android.support.v4.view.ViewPager>

        <com.example.administrator.pulltorefresh.MyList
            android:id="@+id/lv"
            android:layout_width="match_parent"
            android:layout_height="match_parent">

        com.example.administrator.pulltorefresh.MyList>
    LinearLayout>
com.handmark.pulltorefresh.library.PullToRefreshScrollView>

2.fragment中  无限轮播结合listview

private Handler handler=new Handler(){
    @Override
    public void handleMessage(Message msg) {
        super.handleMessage(msg);
        if(msg.what==1){
           vp.setCurrentItem(vp.getCurrentItem()+1);
        }
        handler.sendEmptyMessageDelayed(1,2000);
    }
};
private List<String> imageurl_list;

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.scroll_layout, container, false);
    sw = (PullToRefreshScrollView) v.findViewById(R.id.sw);
    lv = (MyList) v.findViewById(R.id.lv);
    vp = (ViewPager) v.findViewById(R.id.vp);
    return v;
}

@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    //失去焦点
    lv.setFocusable(false);
    //首次加载数据
    getDataFromNet();
    //设置下拉刷新和上拉加载
    sw.setMode(PullToRefreshBase.Mode.BOTH);
    //刷新
    proxy = sw.getLoadingLayoutProxy(true, false);
    proxy.setPullLabel("下拉刷新");
    proxy.setRefreshingLabel("正在刷新");
    proxy.setReleaseLabel("放开刷新");
    //加载
    ILoadingLayout proxy1 = sw.getLoadingLayoutProxy(false, true);
    proxy1.setPullLabel("上拉加载");
    proxy1.setRefreshingLabel("正在加载");
    proxy1.setReleaseLabel("放开加载");
    //刷新的点击事件
    sw.setOnRefreshListener(new PullToRefreshBase.OnRefreshListener2<ScrollView>() {
        @Override
        public void onPullDownToRefresh(PullToRefreshBase<ScrollView> refreshView) {
            NetDataUtil.getData("http://gank.io/api/data/Android/10/1", getActivity(), new JsonCallBack() {
                @Override
                public void getJsonString(String json) {
                    Gson gson = new Gson();
                    DataDataBean dataDataBean = gson.fromJson(json, DataDataBean.class);
                    List<DataDataBean.ResultsBean> results = dataDataBean.getResults();
                    list.addAll(results);
                    setadp();
                    //停止刷新
                    sw.onRefreshComplete();
                }
            });
        }

        @Override
        public void onPullUpToRefresh(PullToRefreshBase<ScrollView> refreshView) {
            page++;
            getDataFromNet();
        }
    });
    //设置无限轮播
    LunBo();

}

private void LunBo() {
    NetDataUtil.getData("http://v3.wufazhuce.com:8000/api/reading/index/?version=3.5.0&platform=android", getActivity(), new JsonCallBack() {
        @Override
        public void getJsonString(String json) {
            imageurl_list= new ArrayList<>();
            Gson gson = new Gson();
            LunBoBean lunBoBean= gson.fromJson(json, LunBoBean.class);
            List<LunBoBean.DataBean.EssayBean> essay = lunBoBean.getData().getEssay();
            for (LunBoBean.DataBean.EssayBean e:essay) {
                List<LunBoBean.DataBean.EssayBean.AuthorBean> author= e.getAuthor();
                String web_url= author.get(0).getWeb_url();
                imageurl_list.add(web_url);
            }
            vp.setAdapter(new MyPageAdp(getActivity(),imageurl_list));
            vp.setCurrentItem(imageurl_list.size()*1000);
            handler.sendEmptyMessageDelayed(1,2000);
        }
    });

}

private void getDataFromNet() {
    NetDataUtil.getData("http://gank.io/api/data/Android/10/" + page, getActivity(), new JsonCallBack() {
        @Override
        public void getJsonString(String json) {
            Gson gson = new Gson();
            DataDataBean dataDataBean = gson.fromJson(json, DataDataBean.class);
            List<DataDataBean.ResultsBean> results = dataDataBean.getResults();
            list.addAll(results);
            setadp();
            //停止刷新
            sw.onRefreshComplete();
        }
    });
}

private void setadp() {
    if (adp == null) {
        adp = new Myadp(getActivity(), list);
        lv.setAdapter(adp);
    } else {
        adp.notifyDataSetChanged();
    }
}

3.适配器

public class MyPageAdp extends PagerAdapter{
    Context context;
    List<String> imageurl_list;
    public MyPageAdp(Context context, List<String> imageurl_list) {
        this.context=context;
        this.imageurl_list=imageurl_list;
    }

    @Override
    public Object instantiateItem(ViewGroup container, int position) {
        ImageView image=new ImageView(context);
        ImageLoader.getInstance().displayImage(imageurl_list.get(position%imageurl_list.size()),image, ImageLoaderUtil.getDefaultOption());
        container.addView(image);
        return image;
    }

    @Override
    public void destroyItem(ViewGroup container, int position, Object object) {
        container.removeView((View) object);
    }

    @Override
    public int getCount() {
        return Integer.MAX_VALUE;
    }

    @Override
    public boolean isViewFromObject(View view, Object object) {
        return view==object;
    }
}

4.自己写一个listview,在布局中代替listview

public class MyList extends ListView{
    public MyList(Context context) {
        super(context);
    }

    public MyList(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public MyList(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);
        super.onMeasure(widthMeasureSpec, expandSpec);

    }
}
