Scrollviewfresh加載數(shù)據(jù) 嵌套NonScrollListView甸祭，NonScrollListView item中包含NonScrollGridView

這個(gè)布局中最外層用的是HeaderViewPager忿晕，大概的效果就是京東店鋪詳情

大致效果是這樣，向上滑動(dòng)奕枢，Tablayout能繼續(xù)選擇fragment ,
起初覺(jué)得這樣嵌套好幾層布局會(huì)出問(wèn)題，最后寫(xiě)完，發(fā)現(xiàn)并沒(méi)有問(wèn)題，重寫(xiě)的Listview

 @Override
    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

        int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,
                MeasureSpec.AT_MOST);
        super.onMeasure(widthMeasureSpec, expandSpec);
    }

重寫(xiě)的Gridview

 @Override
    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

        int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,
                MeasureSpec.AT_MOST);
        super.onMeasure(widthMeasureSpec, expandSpec);
    }

    //通過(guò)重新dispatchTouchEvent方法來(lái)禁止滑動(dòng)
    @Override
    public boolean dispatchTouchEvent(MotionEvent ev) {
        // TODO Auto-generated method stub
        if (ev.getAction() == MotionEvent.ACTION_MOVE) {
            return true;//禁止Gridview進(jìn)行滑動(dòng)
        }
        return super.dispatchTouchEvent(ev);
    }

然后就是下拉能加載的Scrollview

public class Scrollviewfresh extends ScrollView {
    private OnScrollToBottomListener onScrollToBottom;

    public Scrollviewfresh(Context context) {
        super(context);
        // TODO Auto-generated constructor stub
    }

    public Scrollviewfresh(Context context, AttributeSet attrs) {
        super(context, attrs);
        // TODO Auto-generated constructor stub
    }

    public Scrollviewfresh(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        // TODO Auto-generated constructor stub
    }

    @Override
    protected void onOverScrolled(int scrollX, int scrollY, boolean clampedX,
                                  boolean clampedY) {
        // TODO Auto-generated method stub
        super.onOverScrolled(scrollX, scrollY, clampedX, clampedY);
        if (scrollY != 0 && null != onScrollToBottom) {
            onScrollToBottom.onScrollBottomListener(clampedY);
        }
    }

    public void setOnScrollToBottomLintener(OnScrollToBottomListener listener) {
        onScrollToBottom = listener;
    }

    public interface OnScrollToBottomListener {
        public void onScrollBottomListener(boolean isBottom);
    }

這個(gè)下拉加載的scrollview 姑荷，需要再下拉的時(shí)候做下判斷，

 svDisplay.setOnScrollToBottomLintener(new Scrollviewfresh.OnScrollToBottomListener() {
            @Override
            public void onScrollBottomListener(boolean isBottom) {
                isboolean = isBottom + "";
                if (isboolean.equals("true") && isOk.equals("false")) {
                    isOk = "true";
                    page++;
                    httpList();
                }
            }
        });

通過(guò)兩個(gè)boolean來(lái)做判斷锣枝，第一個(gè)isboolean判斷是否滑動(dòng)到最底部厢拭，第二個(gè)就是用來(lái)判斷網(wǎng)絡(luò)請(qǐng)求是否成功，否則會(huì)一直加載網(wǎng)絡(luò)請(qǐng)求撇叁，導(dǎo)致數(shù)據(jù)重復(fù)，

HttpJsonUtil.getShop_New_Goods(shop_id, page + "", 10001, new HttpManager.OnHttpResponseListener() {
            @Override
            public void onHttpResponse(int requestCode, String resultJson, Exception e) {
                if (0 == GetJsonUtil.getResponseCode(resultJson)) {
                    String json = GetJsonUtil.getResponseData(resultJson);
                    bindListData(JSON.parseArray(json, ShopNewGoodsBean.class));
                    if (JSON.parseArray(json, ShopDetailGoodsBean.class).size() == 0) {//沒(méi)有更多數(shù)據(jù)了畦贸，不能繼續(xù)加載
                        isboolean = "false";
                        isOk = "true";
                    } else {
                        isboolean = "false";
                        isOk = "false";
                    }

                } else {
                    showShortToast(GetJsonUtil.getResponseError(resultJson));
                }

至此陨闹，基本上的一個(gè)多嵌套布局，加上一個(gè)下拉加載已經(jīng)做完了薄坏，具體的填充adapter趋厉，就不貼上去了
