2つのタブフラグメントを持つビューページを持つタブレイアウトを持つコンテナとしてフラグメントがあります。メインコンテナのフラグメントの中には、カスタムボタンが付いたツールバーがあり、onclickingは、Webサービスを打つことでタブフラグメントのコンテンツを更新します。Android：サーバから更新されたコンテンツでフラグメントをリロードできません
これは、コンテナフラグメントのコードです。
public class NotificationsFragment extends Fragment {
TabLayout tabLayout = null;
ViewPager viewPagerNotifications = null;
public NotificationsFragment()
{
// Required empty public constructor
}
public static NotificationsFragment newInstance() {
Bundle args = new Bundle();
NotificationsFragment fragment = new NotificationsFragment();
fragment.setArguments(args);
return fragment;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
ViewGroup rootView = (ViewGroup) inflater.inflate(R.layout.fragment_notifications, null);
final Button mButton_right = (Button) getActivity().findViewById(R.id.Button_right);
mButton_right.setVisibility(View.VISIBLE);
final Button mButton_alerts = (Button) getActivity().findViewById(R.id.Button_alerts);
mButton_alerts.setVisibility(View.GONE);
tabLayout = (TabLayout) rootView.findViewById(R.id.TabLayout_notifications);
tabLayout.addTab(tabLayout.newTab().setText("Symptoms"));
tabLayout.addTab(tabLayout.newTab().setText("Diagnosis"));
tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
tabLayout.setSelectedTabIndicatorColor(getResources().getColor(R.color.textColorPrimary));
tabLayout.setSelectedTabIndicatorHeight(8);
tabLayout.setTabTextColors(ContextCompat.getColor(getActivity(),R.color.textColorPrimary),
getResources().getColor(R.color.textColorPrimary));
ViewCompat.setElevation(tabLayout, 5f);
viewPagerNotifications = (ViewPager) rootView.findViewById(R.id.viewPagernotifications);
final NotificationPagerAdapter pagerAdapter = new NotificationPagerAdapter(getFragmentManager(),tabLayout.getTabCount());
viewPagerNotifications.setAdapter(pagerAdapter);
viewPagerNotifications.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
viewPagerNotifications.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
}
@Override
public void onPageSelected(int position) {
Log.e("notif","onpageselected"+position);
}
@Override
public void onPageScrollStateChanged(int state) {

});
tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
@Override
public void onTabSelected(TabLayout.Tab tab) {
viewPagerNotifications.setCurrentItem(tab.getPosition());
switch (tab.getPosition())
{
case 0:
mButton_right.setVisibility(View.VISIBLE);
mButton_alerts.setVisibility(View.GONE);
/* LocalBroadcastManager lbm = LocalBroadcastManager.getInstance(getActivity());
Intent i = new Intent("TAG_REFRESH");

break;
case 1:

}
}
@Override

// Inflate the layout for this fragment

これは、ポケットベルアダプタクラスのコード
public class NotificationPagerAdapter extends FragmentStatePagerAdapter {
final int Illness = 1;
final int Symptoms = 0;
int numOfTabs;
SymptomsTabFragment symptomsTabFragment;
IllnessTabFragment illnessTabFragment;
public NotificationPagerAdapter(FragmentManager fm,int numOfTabs) {

}
@Override
public Fragment getItem(int position) {
switch (position)

symptomsTabFragment = new SymptomsTabFragment();
return symptomsTabFragment;
case Illness:

return null;

ですボタンのテキストに基づいてmButton_rightをクリックすると、「すべて選択」または「すべて選択解除」が更新されます。私の断片の内容それぞれのボタンの選択に関するWebサービスへの呼び出しは、タブ内で正しく行われています。
しかし、更新後に新しいデータを受信するたびに、新しい受信データでタブフラグメントを更新することができません。 更新されたデータを取得し、ボタンをクリックしてタブフラグメントを更新する方法と場所はどこですか？助けてください！
