在Tablayout中显示此类选项卡

我的代码在这里

private int[] imageList= {R.drawable.icon_category,R.drawable.icon_newest};

 tabLayout=(TabLayout)findViewById(R.id.tabs);
    tabLayout.addTab(tabLayout.newTab().setText(""));
    tabLayout.addTab(tabLayout.newTab().setText(""));


    for (int i = 0; i < imageList.length; i++) {
        tabLayout.getTabAt(i).setIcon(imageList[i]);
    }
