Hello I'm implementing a dynamic TabLayout using a single fragment, i have manage to create the tabs so far but there is a problem using a single fragment. When im changing the tabs the fragment view is not updating repeatedly, although im updating the data in the fragment's onCreateView method based on the tab selection. I have a recyclerview in the that fragment which should change according to the tab selection. SO can anyone help me with it or do anyone have a better way of approach?

I have two solution for this.
1) make your view pager offset limit 0. Which default 1. If you are switching another fragment which not in offset, that fragment re-creating.
viewPager.setOffscreenPageLimit(0);
2) Tell your adapter, fragment has been changed. So your adapter will re-create its views again.
rv.notifyDataSetChanged();
I hope these will solve your problem.
First thing as you are using ViewPager, onCreateView() of Fragment will be called only when getItem() of FragmentPagerAdapter will be called.
If need to create a method in Fragment which will call RecyclerView.notifyDataSetChanged().
Check out updated code for both classes

When i try to retrieve category list from server for multiple tab, after set adapter its Toast two ID for the first time .Suppose, When current tab id is ZERO , then its showing next increment ID .
Like the Screenshot its showing 20 in tab 0 .
Basically i want the category id dynamically when i swipe the tab.

Toast.makeText(getContext().getApplicationContext(), storeText, Toast.LENGTH_SHORT).show();
}
In View Pager Bydefault previous and next fragment data is loaded that's why you got next fragment value in toast .
In that you have to set OffscreenPageLimit in viewpager to restrict to load previous and next fragment in View Pager
set value of setOffscreenPageLimit() is 1 .
Hope that above will help you.
I have 2 Tabs as fragments in a ViewPager in an Activity
When I tap the second tab in the layout, the OnTabUnselected method works.
However, when I slide the screen from one tab to another, the method isn't called.
How do I achieve this calling of method by both means "Tapping as well as in a Sliding Gesture"
My Activity class is:
public class OrderActivity extends AppCompatActivity {
private Toolbar toolbar;
private TabLayout tabLayout;
private ViewPager viewPager;
private FloatingActionButton printAction;

You can use the ViewPager.addOnPageChangeListener() method to register a listener and get notified about changing the current tab with a pager swipe.
There is a really nice tutorial here.
In your fragment you can use a method named setVisibilityHint that is called every time the visibility of the fragment has been changed. There is a boolean parameter that can be true or false depending if the fragment is visible or not
#Override
public void setUserVisibleHint(boolean isVisibleToUser) {
super.setUserVisibleHint(isVisibleToUser);
}
As per this accepted answer, I was able to get my tabLyout as below:
What do I need now, is to be able to change the buttons text based on the fragment position, for example if the position is zero, the Back should not appear, and if the position is the last, the Next should be replaced by Done
I have used the ViewPager.OnPageChangeListener but did not work for me, below is the full code:
public class Slider extends AppCompatActivity {
private TabLayout tabLayout;
private ViewPager viewPager;
private Button leftBtn, rightBtn;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.start_up);
leftBtn = (Button) findViewById(R.id.left_btn);
rightBtn= (Button) findViewById(R.id.right_btn);
viewPager = (ViewPager) findViewById(R.id.viewpager);
setupViewPager(viewPager);
tabLayout = (TabLayout) findViewById(R.id.tabLayout);
tabLayout.setupWithViewPager(viewPager);
}
// This is not working, even the `Toast` not appearing
private ViewPager.OnPageChangeListener listener = new ViewPager.OnPageChangeListener() {
#Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
}
#Override
public void onPageSelected(int position) {
Toast.makeText(Slider.this, "Current position: "+position, Toast.LENGTH_SHORT).show();
if (position == 0) {
leftBtn.setText("");
}
if (position == 3) {
rightBtn.setText("DONE");
}
}
#Override
public void onPageScrollStateChanged(int state) {
}
};
private void setupViewPager(ViewPager viewPager) {
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
adapter.addFrag(new Tab1(),"");
adapter.addFrag(new Tab2(),"");
adapter.addFrag(new Tab3(),"");
adapter.addFrag(new Tab4(),"");
viewPager.setAdapter(adapter);
}
static class ViewPagerAdapter extends FragmentPagerAdapter {
private final List<Fragment> mFragmentList = new ArrayList<>();
private final List<String> mFragmentTitleList = new ArrayList<>();
public ViewPagerAdapter(FragmentManager manager) {
super(manager);
}
#Override
public Fragment getItem(int position) {
return mFragmentList.get(position);
}
#Override
public int getCount() {
return mFragmentList.size();
}
public void addFrag(Fragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
#Override
public CharSequence getPageTitle(int position) {
return mFragmentTitleList.get(position);
}
}
public void next_fragment(View view) {
viewPager.setCurrentItem(viewPager.getCurrentItem()+1);
}
public void previous_fragment(View view) {
viewPager.setCurrentItem(viewPager.getCurrentItem()-1);
}
public void start_app(View view) {
startActivity(new Intent(Slider.this, TrustedNumber.class));
finish();
}
}
It's because you haven't added the listener to the viewpager
viewPager.addOnPageChangeListener(listener);
I'm having one parent Fragment whose class is Scrollbaltab which contains many dynamic child Fragment whose class is Fragment1 but when I'm scrolling tab "two" it shows tab "one" data and when scroll to tab "three" it shows tab "two" data please help me

I have implemented a ViewPager in order to swipe between two Fragments like such:
#Override
public View onCreateView(LayoutInflater inflater,
ViewGroup container, Bundle savedInstanceState) {
view = inflater.inflate(R.layout.statistics_general_vp, container, false);
mViewPager = (ViewPager) view.findViewById(R.id.pager);
mStatisticsPagerAdapter = new StatisticsPagerAdapter(getActivity().getSupportFragmentManager());
mViewPager.setAdapter(mStatisticsPagerAdapter);
return view;
}
public class StatisticsPagerAdapter extends FragmentStatePagerAdapter {
public StatisticsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int i) {
return new GeneralStatistics();
}
#Override
public int getCount() {
return NUM_PAGES;
}
}
But for now my two slides display the same Fragment.
How may I have slide 1 display Fragment 1 and slide 2 Fragment 2?
have u created fragment1 and fragment 2 seperately?? if yes then do this - in activity holding these two fragments.
private void createViewPager(ViewPager viewPager) {
Log.d("activity", "viewpager");
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
adapter.addFrag(new Fragment1(), "");
adapter.addFrag(new Fragment2(), "");
viewPager.setAdapter(adapter);
}
create fragment like this -
public class Fragment1 extends Fragment {
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.transaction_layout, container, false);
return v;
}
}
create viewpager like this -
class ViewPagerAdapter extends FragmentPagerAdapter {
private final List<Fragment> mFragmentList = new ArrayList<>();
private final List<String> mFragmentTitleList = new ArrayList<>();
public ViewPagerAdapter(FragmentManager manager) {
super(manager);
}
#Override
public Fragment getItem(int position) {
return mFragmentList.get(position);
}
#Override
public int getCount() {
return mFragmentList.size();
}
public void addFrag(Fragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
#Override
public CharSequence getPageTitle(int position) {
return mFragmentTitleList.get(position);
}
}
or if you want to make tab with icons use this method -
private void createTabIcons() {
Log.d("activity", "createtabicons");
TextView tabOne = (TextView) LayoutInflater.from(this).inflate(R.layout.tab_item2, null);
tabOne.setText("QR Scan");
tabOne.setTypeface(MRR);
tabOne.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.image1, 0, 0);
tabOne.setCompoundDrawablePadding(5);
tabLayout.getTabAt(0).setCustomView(tabOne);
tabLayout.getTabAt(0).getCustomView().setSelected(true);
TextView tabTwo = (TextView) LayoutInflater.from(this).inflate(R.layout.tab_item2, null);
tabTwo.setText("Mobile No.");
tabTwo.setTypeface(MRR);
tabTwo.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.image3, 0, 0);
tabLayout.getTabAt(1).setCustomView(tabTwo);
tabTwo.setCompoundDrawablePadding(5);
}
Hello i show you what i doing, i got 2 fragments in mainActivity
private void addFragments() {
List<Fragment> fragments = new ArrayList<>();
chatFragment = new ChatFragment();
remoteFragment = new RemoteFragment();
fragments.add(remoteFragment);
fragments.add(chatFragment);
MyPageAdapter adapter = new MyPageAdapter(getSupportFragmentManager(), fragments);
viewPager.setAdapter(adapter);
tabLayout.setupWithViewPager(viewPager);
tabLayout.getTabAt(TAB_REMOTE_POSITION)
.setIcon(getDrawable(R.drawable.ic_settings_remote_white_24dp));
tabLayout.getTabAt(TAB_SOCIAL_POSITION)
.setIcon(getDrawable(R.drawable.ic_group_white_24dp));
}
Here is my adapter:
class MyPageAdapter extends FragmentPagerAdapter {
private List<Fragment> fragments;
public MyPageAdapter(FragmentManager fm, List<Fragment> fragments) {
super(fm);
this.fragments = fragments;
}
#Override
public Fragment getItem(int position) {
return this.fragments.get(position);
}
#Override
public int getCount() {
return this.fragments.size();
}
}
and on OnCreate u should
addFragments();
also i bind the views with ButterKnife
#Bind(R.id.view_pager)
ViewPager viewPager;
#Bind(R.id.tab_layout)
TabLayout tabLayout;
but u can static implement this with android
And remember that u have listeners:
private void pageChangeListener() {
viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
#Override
public void onPageScrolled(int position, float positionOffset,
int positionOffsetPixels) {
}
#Override
public void onPageSelected(int position) {
}
#Override
public void onPageScrollStateChanged(int state) {
View view = getCurrentFocus();
if (view != null) {
InputMethodManager imm = (InputMethodManager) getSystemService
(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}
}
});
}
