应该设置哪些 viewpager 设置？

Question

我的应用程序有 3 个选项卡：tablayout、带片段寻呼机适配器的 viewpager。我有一个问题：第一个选项卡到第二个选项卡到第三个选项卡并返回到第一个选项卡片段重新启动。

TextTabAdapter adapter = new TextTabAdapter(getSupportFragmentManager(), 1, fragmentList, tabTitleList); 
viewPager.setAdapter(adapter); 
tabLayout.setupWithViewPager(viewPager);

Answer 1

TextTabAdapter adapter = new TextTabAdapter(getSupportFragmentManager(), 1, fragmentList, tabTitleList); 
viewPager.setAdapter(adapter); 
tabLayout.setupWithViewPager(viewPager);
//set viewpager off screens, By default , it is one. 
viewPager.setOffscreenPageLimit(tabTitleList.size());
