Android TabLayout设置setupWithViewPager标题不显示

viewList = new ArrayList<>();
		for (int i = 0; i < 3; i++) {
			tb_inspection_facility_room.addTab(tb_inspection_facility_room.newTab().setText("tab"+i));
			View view = inflater.from(this).inflate(R.layout.inspection_viewpager_facility_page,null);
			TextView textView = view.findViewById(R.id.textview);
			textView.setText("Page"+i);
		}
		pagerAdapter = new InspectionRoomPagerAdapter(viewList);
		vp_inspection_facility_room.setAdapter(pagerAdapter);
		tb_inspection_facility_room.setupWithViewPager(vp_inspection_facility_room);

在设置setupWithViewPager后标题没有如愿的显示出来，其实是Tablayout调用viewpager的getTItle方法的时候导致没有数据展示出来，源码：

addTab(newTab().setText(mPagerAdapter.getPageTitle(i)), false);

解决方法就是在pagerAdapter里的

@Nullable
	@Override
	public CharSequence getPageTitle(int position) {
		return titleList.get(position);
	}

返回你想要的标题就行了

解决后：

viewList = new ArrayList<>();
		List<String> titleList = new ArrayList<>();
		for (int i = 0; i < 3; i++) {
			titleList.add("title"+i);
			tb_inspection_facility_room.addTab(tb_inspection_facility_room.newTab().setText("tab"+i));
			View view = inflater.from(this).inflate(R.layout.inspection_viewpager_facility_page,null);
			TextView textView = view.findViewById(R.id.textview);
			textView.setText("Page"+i);
			viewList.add(view);
		}
		pagerAdapter = new InspectionRoomPagerAdapter(viewList,titleList);
		vp_inspection_facility_room.setAdapter(pagerAdapter);
		tb_inspection_facility_room.setupWithViewPager(vp_inspection_facility_room);
