如何在android中的选项卡顶部显示选项卡指示器？

Question

I have an app in which I have added TabLayout with three tabs. I want to show tab indicator from bottom to top but the problem is that when I show indicator from bottom to top tab icon also rotate.How do I resolve this issue?

    mTabLayout.getTabAt(0).setCustomView(view);
    mTabLayout.getTabAt(1).setIcon(tabIcons[1]);
    mTabLayout.getTabAt(2).setIcon(tabIcons[2]);
    mTabLayout.setRotationX(180);

I have similar requirement in my previous application

Please try below code it works perfectly for me

//First rotate the tab layout
     tabOrderType.setRotationX(180);

//Find all childs for tablayout
            for (int i = 0; i <tabOrderType.getChildCount() ; i++) {
                    LinearLayout linearList = ((LinearLayout)tabOrderType.getChildAt(i));

                    for(int position = 0;position<linearList.getChildCount();position++) {
//One by one again rotate layout for text and icons
                        LinearLayout item=((LinearLayout) linearList.getChildAt(position));
                        item.setBackground(getResources().getDrawable(R.drawable.custom_button_border));
                        item.setRotationX(180);
                    }
                }

This is working nicely in my application and not creating any issue till now.Another way is you need to make custom tab to manage this.

Hope this helps you...if any issue please ask me...

将此添加到您的 TabLayout XML 中

app:tabIndicatorGravity="top"
