I am working on an android app with viewpager and Tablayout. This is my view pager fragment which opens from a parent activity
public class HomeFragment extends Fragment{
private SectionsPagerAdapter mSectionsPagerAdapter;
private ViewPager mViewPager;
public HomeActivity() {
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_home, container, false);
mSectionsPagerAdapter = new SectionsPagerAdapter(getFragmentManager());
mViewPager = (ViewPager) rootView.findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
TabLayout tabLayout = (TabLayout) rootView.findViewById(R.id.tabs);
tabLayout.setupWithViewPager(mViewPager);
return rootView;
}
}
this is my adapter for viewpager
public class SectionsPagerAdapter extends FragmentStatePagerAdapter {
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
switch (position){
case 0 : return new Settingsfragment();
case 1 : return new Profilefragment();
case 2 : return new Categoriesfragment();
}
return null;
}
#Override
public int getCount() {
// Show 3 total pages.
return 3;
}
#Override
public CharSequence getPageTitle(int position) {
switch (position) {
case 0:
return "settings";
case 1:
return "profile";
case 2:
return "Category";
}
return null;
}
}
when I open a fragment with the code below and press back viewpager become empty
public class Profilefragment extends Fragment {
public Profilefragment(){}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.profile_layout, container, false);
TextView VE = (TextView) rootView.findViewById(R.id.profile_view_enquiry);
VE.setOnClickListener(new View.OnClickListener(){
public void onClick (View view){
Fragment fragment = null;
fragment = new Enquiryfragment();
replaceFragment(fragment);
}
});
TextView CA = (TextView) rootView.findViewById(R.id.profile_change_address);
CA.setOnClickListener(new View.OnClickListener(){
public void onClick (View view){
Fragment fragment = null;
fragment = new ChangeAddressfragment();
replaceFragment(fragment);
}
});
return rootView;
}
public void replaceFragment(Fragment someFragment) {
android.support.v4.app.FragmentTransaction transaction = getFragmentManager().beginTransaction();
transaction.replace(R.id.containerView, someFragment);
transaction.addToBackStack(null);
transaction.commit();
}}
How can I fix this. Please Help.
public class HomeFragment extends Fragment{
private SectionsPagerAdapter mSectionsPagerAdapter;
private ViewPager mViewPager;
public HomeFragment() {}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_home, container, false);
mSectionsPagerAdapter = new SectionsPagerAdapter(getChildFragmentManager());//Changed here
mViewPager = (ViewPager) rootView.findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
TabLayout tabLayout = (TabLayout) rootView.findViewById(R.id.tabs);
tabLayout.setupWithViewPager(mViewPager);
return rootView;
}
}
You should use getChildFragmentManager() instead of getFragmentManager() in Fragment

Once my application is Login I start ActivityTwo. In ActivityTwo I am immediately calling TabView Fragment which hold my three Tabs.This is code in ActivityTwo to call TabView Fragment
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_two);
fm = getSupportFragmentManager();
final Bundle bundle = new Bundle();
bundle.putInt("TARGET_FRAGMENT_ID", fragId);
ChooseTab chooseTab = new ChooseTab();
chooseTab.setArguments(bundle);
ft = fm.beginTransaction();
ft.replace(R.id.frame, chooseTab, add);
ft.commit();
});
This is code for ChooseTab Fragment which is responsible for setting TabView
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View v = inflater.inflate(R.layout.choose_tab, container, false);
//-----------------------------------------------------------------------------------
int position=getArguments().getInt("TARGET_FRAGMENT_ID");
tabLayout = (TabLayout) v.findViewById(R.id.simpleTabLayout);
tabLayout.addTab(tabLayout.newTab().setText("Tab1"));
tabLayout.addTab(tabLayout.newTab().setText("Tab2"));
tabLayout.addTab(tabLayout.newTab().setText("Tab3"));
viewPager = (ViewPager) v.findViewById(R.id.simpleViewPager);
viewPager.setOffscreenPageLimit(3);
final PagerAdapter adapter = new PagerAdapter(getActivity().getSupportFragmentManager(), tabLayout.getTabCount());
viewPager.setAdapter(adapter);
viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
viewPager.setCurrentItem(position);
tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
#Override
public void onTabSelected(TabLayout.Tab tab) {
viewPager.setCurrentItem(tab.getPosition());
adapter.notifyDataSetChanged();
}
#Override
public void onTabUnselected(TabLayout.Tab tab) {
viewPager.setCurrentItem(tab.getPosition());
adapter.notifyDataSetChanged();
}
#Override
public void onTabReselected(TabLayout.Tab tab) {
viewPager.setCurrentItem(tab.getPosition());
adapter.notifyDataSetChanged();
}
});
return v;
}
This is code for PagerAdapter
public class PagerAdapter extends FragmentStatePagerAdapter {
private int mNumOfTabs;
public PagerAdapter(FragmentManager fm, int NumOfTabs) {
super(fm);
this.mNumOfTabs = NumOfTabs;
}
#Override
public Fragment getItem(int position) {
switch (position) {
case 0:
return new Tab1();
case 1:
return new Tab2();
case 2:
return new Tab3();
default:
return null;
}
}
#Override
public int getCount() {
return mNumOfTabs;
}
}
This is code for Tab1 onCreateView
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
// Inflate the layout for this fragment
View v = inflater.inflate(R.layout.current_status, container, false);
fm = getFragmentManager();
LoadData();
});
return v;
}
But when I run the app and I print some Log when LoadData() is called it is seen loadData is called. How to resolve this ?

setupViewPager(viewPager);
tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);
}
private void setupViewPager(ViewPager viewPager) {
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
adapter.addFragment(new ArtistsTab(), "ArtistsTab");
adapter.addFragment(new SongsTab(), "Songs");
//Do your stuff here
viewPager.setAdapter(adapter);

I have a TabLayout Activity, and for one of the tabs (case 3) i want to use a PreferenceFragment for a settings page. In case 3 below i've declared the fragment, but how do I start it?
public static class SettingsFragment extends PreferenceFragment {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Load the preferences from an XML resource
addPreferencesFromResource(R.xml.preferences);
}
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = null;
switch (getArguments().getInt(ARG_SECTION_NUMBER)) {
case 1: {
rootView = inflater.inflate(R.layout.fragment_profile, container, false);
break;
}
case 2: {
rootView = inflater.inflate(R.layout.fragment_find, container, false);
break;
}
case 3: {
SettingsFragment fragment = new SettingsFragment();
// what goes here?
break;
}
}
return rootView;
}
full code:
public class Find extends AppCompatActivity {
private SectionsPagerAdapter mSectionsPagerAdapter;
private ViewPager mViewPager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

// Set up the ViewPager with the sections adapter.
mViewPager = (ViewPager) findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(mViewPager);
TabLayout.Tab tab1 = tabLayout.getTabAt(0);
tab1.setCustomView(R.layout.icon_view);
tab1.setIcon(R.drawable.profile);
TabLayout.Tab tab2 = tabLayout.getTabAt(1);

Separate SettingsFragment from PlaceholderFragment
Update SectionsPagerAdapter's getItem() method to show SettingsFragment for 3rd TAB.
Remove case 3 from onCreateView().
Try this:
public class Find extends AppCompatActivity {
private SectionsPagerAdapter mSectionsPagerAdapter;
private ViewPager mViewPager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_find);
// Create the adapter that will return a fragment for each of the three
// primary sections of the activity.
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
// Set up the ViewPager with the sections adapter.
mViewPager = (ViewPager) findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(mViewPager);
TabLayout.Tab tab1 = tabLayout.getTabAt(0);
tab1.setCustomView(R.layout.icon_view);
tab1.setIcon(R.drawable.profile);
TabLayout.Tab tab2 = tabLayout.getTabAt(1);
tab2.setCustomView(R.layout.icon_view);
tab2.setIcon(R.drawable.logo_a);
TabLayout.Tab tab3 = tabLayout.getTabAt(2);
tab3.setCustomView(R.layout.icon_view);
tab3.setIcon(R.drawable.settings);
}
public static class SettingsFragment extends PreferenceFragment {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Load the preferences from an XML resource
addPreferencesFromResource(R.xml.preferences);
}
}
public static class PlaceholderFragment extends Fragment {
private static final String ARG_SECTION_NUMBER = "section_number";
public PlaceholderFragment() {
}
/**
* Returns a new instance of this fragment for the given section
* number.
*/
public static PlaceholderFragment newInstance(int sectionNumber) {
PlaceholderFragment fragment = new PlaceholderFragment();
Bundle args = new Bundle();
args.putInt(ARG_SECTION_NUMBER, sectionNumber);
fragment.setArguments(args);
return fragment;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = null;
switch (getArguments().getInt(ARG_SECTION_NUMBER)) {
case 1: {
rootView = inflater.inflate(R.layout.fragment_profile, container, false);
break;
}
case 2: {
rootView = inflater.inflate(R.layout.fragment_find, container, false);
break;
}
}
return rootView;
}
}
/**
* A {#link FragmentPagerAdapter} that returns a fragment corresponding to
* one of the sections/tabs/pages.
*/
public class SectionsPagerAdapter extends FragmentPagerAdapter {
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
// getItem is called to instantiate the fragment for the given page.
// Return a PlaceholderFragment (defined as a static inner class below).
switch (position) {

}
case 2: {

return fragment;
}
}
return PlaceholderFragment.newInstance(1);
}
#Override
public int getCount() {
// Show 3 total pages.
return 3;
}
}
}
UPDATE:
To resolve this error you have to use PreferenceFragmentCompat:
1. To use PreferenceFragmentCompat, add below line under dependencies in your build.gradle file:
dependencies {
.........
...............
compile 'com.android.support:preference-v7:25.1.0'
}
2. Extend your SettingsFragment from PreferenceFragmentCompat instead of PreferenceFragment.
import android.support.v7.preference.PreferenceFragmentCompat;
.........
.................
public static class SettingsFragment extends PreferenceFragmentCompat {
#Override
public void onCreatePreferences(Bundle savedInstanceState, String rootKey) {
// Load the preferences from an XML resource
addPreferencesFromResource(R.xml.preferences);
}
}
.........
.................
3. You must specify preferenceTheme in your theme:
styles.xml:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
.......
...........
<item name="preferenceTheme">#style/PreferenceThemeOverlay</item>
</style>
You can also check tutorial to learn more about PreferenceFragmentCompat.
Hope this will help~
I have a fragment that Contains view pager.there are three fragments in that Main fragment they are Fragment A,Fragment B,Fragment C. Upto this code runs properly.
Then i added a new Fragment and called via Fragment A then i got the error in the Log

here's a portion of my code:
public class MenuExpenses extends Fragment {
private ViewPager viewPager;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setRetainInstance(true);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View root = inflater.inflate(R.layout.expenses,container, false);
viewPager = (ViewPager) root.findViewById(R.id.pager);
viewPager.setAdapter(new MyPagerAdapter(getChildFragmentManager()));
// Bind the tabs to the ViewPager
PagerSlidingTabStrip tabs = (PagerSlidingTabStrip) root.findViewById(R.id.tabs);
tabs.setViewPager(viewPager);
return root;
}
private class MyPagerAdapter extends FragmentPagerAdapter {
public MyPagerAdapter(FragmentManager fm) {
super(fm);
}
private final String[] TITLES = { "Daily", "Recurring" };
#Override
public Fragment getItem(int pos) {
switch(pos) {
case 0: return new MenuExpensesDaily();
case 1: return new IncomeList2();
default: return new MenuExpensesDaily();
}
}
}
}
MenuExpensesDaily & IncomeList2 are both fragments. So how can I set the fragment tag for both of them here?
You can override the instantiateItem method, the save the fragment to a SparseArray/HashMap, then create a method to return the fragment with the position. Now you will be able to access your selected your fragment and set the tag to it.
