在选项卡布局中添加和删除选项卡

Question

伙计们，我的布局中有三个选项卡，在另一个活动中，我有一个多选对话框来选择我希望在我的布局中可见或不可见的选项卡，但我无法理解如何从布局中删除和添加选项卡和片段

public class TabAdapter extends FragmentStatePagerAdapter {

private String[] tituloTabs = {"X","Y","Z"};

public TabAdapter(@NonNull FragmentManager fm) {
super(fm);
}

@NonNull
@Override
public Fragment getItem(int position) {
Fragment fragment = null;
switch (position){
case 0 :
fragment = new XFragment();
break;
case 1 :
fragment = new YFragment();
break;
case 2:
fragment = new ZFragment();
break;
}
return fragment;
}
@Override
public int getCount() {
return tituloTabs.length;
}

@Nullable
@Override
public CharSequence getPageTitle(int position) {
return tituloTabs[position];
}

活动代码

SlidingTabLayout slidingTabLayout = findViewById(R.id.stl_tabs);
viewPager =  findViewById(R.id.vp_pagina);
viewPager.setPageTransformer(true,new ZoomOutPageTransformer());

//---------------------------Configurar Sliding Tab--------------------------------------
slidingTabLayout.setSelectedIndicatorColors(ContextCompat.getColor(this,R.color.colorPrimary));
slidingTabLayout.setDistributeEvenly(true);
slidingTabLayout.setBackgroundColor( ContextCompat.getColor( this, R.color.black ) );
//-----------------------------Configurar Adapter ----------------------------------------
TabAdapter tabAdapter = new TabAdapter(getSupportFragmentManager());
viewPager.setAdapter(tabAdapter);
slidingTabLayout.setViewPager(viewPager);

Answer 1

在选项卡布局中添加选项卡

TabLayout tabLayout = findViewById(R.id.stl_tabs);
tablayout.addTab(tabLayout.newTab().setText("Tab1"))
tablayout.addTab(tabLayout.newTab().setText("Tab2"))
tablayout.addTab(tabLayout.newTab().setText("Tab3"))

在选项卡适配器获取项开关案例中

选项卡 1 -> 案例 0 片段

选项卡 2 -> 案例 1 片段

Tab3 -> 案例 2 片段

Answer 2

我设法找到了解决问题的方法，用 ArrayList 替换了数组，并实现了以这种方式添加删除片段和标题的方法

public TabAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position) {
return mFragmentList.get(position);
}
public void addFragment(Fragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
public void removeitem(int position){
mFragmentList.remove(position);
}
public void removetitle(int position){
mFragmentTitleList.remove(position);
}
@Nullable
@Override
public CharSequence getPageTitle(int position) {
return mFragmentTitleList.get(position);
}
@Override
public int getCount() {
return mFragmentList.size();
}
@Override
public int getItemPosition(Object object){
return PagerAdapter.POSITION_NONE;
}}
