類型1：RecyclerView實現(xiàn)非分頁效果的左右滑動

private void initTypeRecyclerView(int rowNum) {
        final RecyclerView topicRecyclerView = findViewById(R.id.topicRecyclerView);
        final View mIndicatorLayout = findViewById(R.id.parent_layout);
        final View mIndicatorView = findViewById(R.id.main_line);

        TopicAdapter topicAdapter = new TopicAdapter(getApplicationContext(), mTopicData);
        topicAdapter.setOnItemClickListener(this);

        topicRecyclerView.setAdapter(topicAdapter);
        GridLayoutManager gridLayoutManager = new GridLayoutManager(getApplicationContext(), rowNum);
        gridLayoutManager.setOrientation(LinearLayoutManager.HORIZONTAL);

        topicRecyclerView.setLayoutManager(gridLayoutManager);
        topicRecyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
            @Override
            public void onScrollStateChanged(@NonNull RecyclerView recyclerView, int newState) {
                super.onScrollStateChanged(recyclerView, newState);

            }

            @Override

                super.onScrolled(recyclerView, dx, dy);

                //當前RcyclerView顯示區(qū)域的高度。水平列表屏幕從左側(cè)到右側(cè)顯示范圍
                int extent = recyclerView.computeHorizontalScrollExtent();

                //整體的高度，注意是整體，包括在顯示區(qū)域之外的。
                int range = recyclerView.computeHorizontalScrollRange();

                //已經(jīng)滾動的距離，為0時表示已處于頂部。
                int offset = recyclerView.computeHorizontalScrollOffset();

                //計算出溢出部分的寬度，即屏幕外剩下的寬度
                float maxEndX = range - extent;

                //計算比例
                float proportion = offset / maxEndX;

                int layoutWidth = mIndicatorLayout.getWidth();
                int indicatorViewWidth = mIndicatorView.getWidth();

                //可滑動的距離
                int scrollableDistance = layoutWidth - indicatorViewWidth;

                //設(shè)置滾動條移動
                mIndicatorView.setTranslationX(scrollableDistance * proportion);
            }
        });

    }

類型2 ：ViewPager+RecyclerView實現(xiàn)分頁效果的左右滑動

private void initTypeViewPager(int rowNum, int columnNum) {

        int singlePageDatasNum = rowNum * columnNum; //每個單頁包含的數(shù)據(jù)量：2*4=8；
        int pageNum = mTopicData.size() / singlePageDatasNum;//算出有幾頁菜單：20%8 = 3;
        if (mTopicData.size() % singlePageDatasNum > 0) pageNum++;//如果取模大于0，就還要多一頁出來，放剩下的不滿項
        ArrayList<RecyclerView> mList = new ArrayList<>();
        for (int i = 0; i < pageNum; i++) {
            RecyclerView recyclerView = new RecyclerView(getApplicationContext());
            GridLayoutManager gridLayoutManager = new GridLayoutManager(getApplicationContext(), columnNum);
            recyclerView.setLayoutManager(gridLayoutManager);
            int fromIndex = i * singlePageDatasNum;
            int toIndex = (i + 1) * singlePageDatasNum;
            if (toIndex > mTopicData.size()) toIndex = mTopicData.size();
            //a.截取每個頁面包含數(shù)據(jù)
            ArrayList<TopicBean> menuItems = new ArrayList<TopicBean>(mTopicData.subList(fromIndex, toIndex));

            TopicAdapter menuAdapter = new TopicAdapter(getApplicationContext(), menuItems);
            menuAdapter.setOnItemClickListener(this);
            //c.綁定適配器，并添加到list
            recyclerView.setAdapter(menuAdapter);
            mList.add(recyclerView);
        }
        //2.ViewPager的適配器
        HomeTopicPagerAdapter menuViewPagerAdapter = new HomeTopicPagerAdapter(mList);
        topicViewPager.setAdapter(menuViewPagerAdapter);
        //3.動態(tài)設(shè)置ViewPager的高度，并加載所有頁面
        int height = dp2px(getApplicationContext(), 76.0f);//這里的80為MainMenuAdapter中布局文件高度
        LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, mTopicData.size() <= columnNum ? height : height * rowNum);
        topicViewPager.setLayoutParams(layoutParams);
        topicViewPager.setOffscreenPageLimit(pageNum - 1);

        //4.創(chuàng)建指示器
        CommonNavigator commonNavigator = new CommonNavigator(getApplicationContext());
        commonNavigator.setAdjustMode(true);
        final int finalPageNum = pageNum;

        commonNavigator.setAdapter(new CommonNavigatorAdapter() {
            @Override
            public int getCount() {
                return finalPageNum;
            }

            @Override
            public IPagerTitleView getTitleView(Context context, int index) {
                return new DummyPagerTitleView(context);
            }

            @Override
            public IPagerIndicator getIndicator(Context context) {
                LinePagerIndicator indicator = new LinePagerIndicator(context);
                indicator.setMode(LinePagerIndicator.MODE_EXACTLY);
                indicator.setLineHeight(UIUtil.dip2px(context, 3));//就是指示器的高
                indicator.setLineWidth(UIUtil.dip2px(context, 66 / finalPageNum));//就是指示器的寬度，然后通過頁數(shù)來評分
                indicator.setRoundRadius(UIUtil.dip2px(context, 3));
                indicator.setStartInterpolator(new AccelerateInterpolator());
                indicator.setEndInterpolator(new DecelerateInterpolator(3));
                indicator.setColors(ContextCompat.getColor(context, R.color.colorAccent));
                return indicator;
            }
        });
        //5.配置指示器，并和ViewPager產(chǎn)生綁定
        topicIndicator.setNavigator(commonNavigator);
        ViewPagerHelper.bind(topicIndicator, topicViewPager);
