//底部foot

    LayoutInflater layoutInflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);    relativeLayout_foot = layoutInflater.inflate(R.layout.activity_footview, null);    img_icon_repeat_works_back = (ImageView) findViewById(R.id.img_icon_repeat_works_back);

//listView    lv_repeat_works = (ListView) findViewById(R.id.lv_repeat_works);

//ListView绑定监听    lv_repeat_works.setOnScrollListener(this);    img_icon_repeat_works_back.setOnClickListener(new View.OnClickListener() {        @Override        public void onClick(View view) {            finish();        }    });}//设置Adapterprivate void setAdapter(List<TaskForwardList> taskForwardLists) {    if(repeatAdapter == null) {        repeatAdapter = new RepeatAdapter(ForwardActivity.this, taskForwardLists);        lv_repeat_works.setAdapter(repeatAdapter);    } else {        repeatAdapter.notifyDataSetChanged();    }    repeatAdapter.notifyDataSetChanged();}/**最重要的是在这个上拉的动作中添加所需要的逻辑*/@Overridepublic void onScrollStateChanged(AbsListView absListView, int i) {//判断listView上拉动作    if(isLoad && i == AbsListView.OnScrollListener.SCROLL_STATE_IDLE) {        topage++;        if(topage>BaseApplication.getTotalPage()) {            return;        }        getForwardData(topage);    }}@Overridepublic void onScroll(AbsListView absListView, int i, int i1, int i2) {    isLoad = ((i+i1) == i2);}//一下是用nohttp加载的数据 ，不懂的可以先去了解下nohttp这个加载数据的框架，我也只是菜鸟一枚private void getForwardData(int page) {    user = SPUtils.getObject("user", User.class);    Request<String> request = NoHttp.createStringRequest(BASE_HTTP_URL + "Forward/ArticalList");    request.addHeader("access-key", user.getToken());    request.add("page", page);    request.add("pageSize", 10);    request.add("catalogID", 2);    callSever.add(this, TASK_FORWARD_LIST, request, this, true, true);}

本人菜鸟一个也是第一次记录自己的东西，有很多东西也不懂，请大家见谅!
