嗨朋友们请帮帮我。我被困在这里超过2天，我不明白这里的错误是什么。我的问题是，我正在创建带有基于JSON数据的图标的选项卡，问题是图标即将到来，但是当片段中的剩余数据加载时它们就消失了。但是当我移除适配器时，图标即将到来，它们是在这里看到我发现了一个错误，当我评论这一行 sticker_tab.setupWithViewPager（sticker_pager）; 然后一切正常，但无法根据viewpager更改或反之亦然移动选项卡 这是我的代码：

根据viewpager更改标签：
viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
@Override
public void onTabSelected(TabLayout.Tab tab) {
viewPager.setCurrentItem(tab.getPosition());
}
@Override
public void onTabUnselected(TabLayout.Tab tab) {
}
@Override
public void onTabReselected(TabLayout.Tab tab) {
}
});

rendering答案 2 :(得分：1)
遵循此ViewPager实施，您可以动态创建标签：
viewPager = (ViewPager) view.findViewById(R.id.viewPager);
//adapter view
androidAdapter = new ViewPagerAdapter(getFragmentManager());
viewPager.setAdapter(androidAdapter);
viewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {
@Override
public void onPageSelected(int tabposition) {
tabHost.setSelectedNavigationItem(tabposition);
}
});
// role = 1; //admin
// role = 2; //master
role = 3; //student
// Creating Dynamic TAB
switch (role){
case 1:
break;
case 2:
// MASTERLOGIN
tabHost.addTab(tabHost.newTab().setText("Slot History").setTabListener(this));
tabHost.addTab(tabHost.newTab().setText("Create Template").setTabListener(this));
tabHost.addTab(tabHost.newTab().setText("Scheduled").setTabListener(this));
tabHost.setSelectedNavigationItem(1);
viewPager.setCurrentItem(1);
//--MASTERLOGIN
break;
case 3:
//STUDENTLOGIN
tabHost.addTab(tabHost.newTab().setText("Products").setTabListener(this));
tabHost.addTab(tabHost.newTab().setText("Book A Slot").setTabListener(this));
tabHost.addTab(tabHost.newTab().setText("Scheduled").setTabListener(this));
tabHost.setSelectedNavigationItem(1);
viewPager.setCurrentItem(1);
//--STUDENT LOGIN
break;
default:
break;
}
