I am able to get DFragment on top of AFragment and on press back of DFragment I am getting AFragment. But the problem that I am facing is when AFragment is shown,BFragment and CFragment show their respective layouts. But when I traverse from A to D, then B and C show D's layouts only.
I have tried notifyDataSetChanged on the Adapter but still doesn't work properly. Please help
My MainActivity
public class MainActivity extends FragmentActivity {
ViewPager pager;
ViewPagerAdapter adapter;
SlidingTabLayout tabs;
CharSequence tabTitles[] = {"A", "B", "C"};
int numTabs = 3;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
adapter = new ViewPagerAdapter(getSupportFragmentManager(), tabTitles, numTabs);
pager = (ViewPager) findViewById(R.id.pager);
pager.setAdapter(adapter);
tabs = (SlidingTabLayout) findViewById(R.id.tabs);
tabs.setDistributeEvenly(true);
tabs.setCustomTabColorizer(new SlidingTabLayout.TabColorizer() {
#Override
public int getIndicatorColor(int position) {
return getResources().getColor(R.color.tabsScrollColor);
}
});
tabs.setViewPager(pager);
}
}
This is my ViewPagerAdapter
public class ViewPagerAdapter extends FragmentStatePagerAdapter {
CharSequence tabTitles[];
int numTabs;
public ViewPagerAdapter(FragmentManager fm,CharSequence tabTitles[], int numTabs) {
super(fm);
this.tabTitles = tabTitles;
this.numTabs = numTabs;
}
#Override
public Fragment getItem(int position) {
if(position==0)
return new AFragment();
else
if(position==1)
return new BFragment();
else
return new CFragment();
}
#Override
public int getCount() {
return numTabs;
}
#Override
public CharSequence getPageTitle(int position) {
return tabTitles[position];
}
}
This is my 0th fragment
public class AFragment extends Fragment{
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState){
View rootView =inflater.inflate(R.layout.a,container,false);
Button b = (Button)rootView.findViewById(R.id.b);
b.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
((MainActivity) context).getSupportFragmentManager().beginTransaction().add(R.id.container, new DFragment())
.addToBackStack("").commit();
}
});
return rootView;
}
}
This is the new fragment that comes on top of my 0th fragment
public class DFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_d,null);
return rootView;
}
}

I created two fragments: 'scheduleFragment' and 'clockFragment'. After setting up
public class ClockFragment extends AppCompatActivity implements View.OnClickListener {
private int notificationId = 1;
in MainActivity.java, the pageAdapter
scheduleFragment = new ScheduleFragment();
clockFragment = new ClockFragment();
tabLayout.setupWithViewPager(viewPager);
ViewPagerAdapter viewPagerAdapter = new ViewPagerAdapter(getSupportFragmentManager(), 0);
viewPagerAdapter.addFragment(clockFragment, "Clock");
viewPagerAdapter.addFragment(scheduleFragment, "Schedule");
viewPager.setAdapter(viewPagerAdapter);
creates an error that states I have to switch refactor the clockFragment into the scheduleFragment so one fragment is created.
I need these two fragments because, in the ClockFragment (tab), the clock must appear to users and on the ScheduleFragment (tab), the schedule of users is present. I am not sure how I can separate the two tabs without causing an error.
Some explanation over why this error occurs and a solution will be greatly appreciated.
public class MainActivity extends AppCompatActivity {
private Toolbar toolbar;
private ViewPager viewPager;
private TabLayout tabLayout;
private ScheduleFragment scheduleFragment;
private ClockFragment clockFragment;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ViewPager viewPager = findViewById(R.id.view_pager);
viewPager.setAdapter(new ViewPagerAdapter(getSupportFragmentManager()));
toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
viewPager = findViewById(R.id.view_pager);
tabLayout = findViewById(R.id.tab_layout);
scheduleFragment = new ScheduleFragment();
clockFragment = new ClockFragment();
tabLayout.setupWithViewPager(viewPager);
tabLayout.getTabAt(0).setIcon(R.drawable.ic_baseline_add_alarm_24);
tabLayout.getTabAt(1).setIcon(R.drawable.ic_baseline_assignment_turned_in_24);
}
private class ViewPagerAdapter extends FragmentPagerAdapter {
private List<Fragment> fragments = new ArrayList<>();
private List<String> fragmentTitle = new ArrayList<>();
public ViewPagerAdapter(#NonNull FragmentManager fm, int behavior) {
super(fm, behavior);
}
public ViewPagerAdapter(FragmentManager supportFragmentManager) {
super(supportFragmentManager);
}
public void addFragment(ClockFragment fragment, String title) {
fragments.add(fragment);
fragmentTitle.add(title);
}
#NonNull
#Override
public Fragment getItem(int position) {
return fragments.get(position);
}
#Override
public int getCount() {
return fragments.size();
}
#Nullable
#Override
public CharSequence getPageTitle(int position) {
return fragmentTitle.get(position);
}
}
}
First ClockFragment extends Activity which means it is not a fragment.
I will give you an example of how you should do things:
public class ChildFragment1 extends Fragment {
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
super.onCreateView(inflater, container, savedInstanceState);
View rootView = inflater.inflate(R.layout.child_fragment_1_layout, container, false);
Button buttonInFragment1 = rootView.findViewById(R.id.button_1);
buttonInFragment1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(getContext(), "button in fragment 1", Toast.LENGTH_SHORT).show();
}
});
return rootView;
}
}
Now do Fragment 2:
public class ChildFragment2 extends Fragment {
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
super.onCreateView(inflater, container, savedInstanceState);
View rootView = inflater.inflate(R.layout.child_fragment_1_layout, container, false);
Button buttonInFragment1 = rootView.findViewById(R.id.button_1);
buttonInFragment1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(getContext(), "button in fragment 2", Toast.LENGTH_SHORT).show();
}
});
return rootView;
}
}
Now add a new class for the adapter:
public class ViewPagerAdapter extends FragmentPagerAdapter {
public ViewPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
switch (position)
{
case 0:
return new ChildFragment1(); //ChildFragment1 at position 0
case 1:
return new ChildFragment2(); //ChildFragment2 at position 1
}
return null; //does not happen
}
#Override
public int getCount() {
return 2; //three fragments
}
}
And your MainActivity would look something like this:
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ViewPager viewPager = findViewById(R.id.view_pager);
viewPager.setAdapter(new ViewPagerAdapter(getSupportFragmentManager()));
}
}
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);
}
}
});
}
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

I am trying to swipe item(from listview) in my detail activity using viewpager.
I have 20 items in my listview (data parsed from json) Instead of swiping the next/previous item , It's only the same item that I swipe (20 times).
here is my DetailActivity.
public class DetailsActivity extends FragmentActivity {
Article feed;
int pos;
private DescAdapter adapter;
private ViewPager pager;
...
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.item_details);
pos = getIntent().getExtras().getInt("pos");
adapter = new DescAdapter(getSupportFragmentManager());
pager = (ViewPager) findViewById(R.id.pager);
pager.setAdapter(adapter);
pager.setCurrentItem(pos);
}
public class DescAdapter extends FragmentStatePagerAdapter {
public DescAdapter(FragmentManager fm) {
super(fm);
}
#Override
public int getCount() {
return 20;
}
public Fragment getItem(int position) {
return DetailFragment.newInstance(position);
}
}
And my detailFragment
public class DetailFragment extends Fragment {
static DetailFragment newInstance(int position) {
DetailFragment f = new DetailFragment();
return f;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.detail_fragment, container, false);
String displaytitle= getActivity().getIntent().getStringExtra("title");
TextView titleF = (TextView)view.findViewById(R.id.title);
titleF.setText(displaytitle);
...
return view;
}
What am I doing wrong?
You are not using the correct argument:
You send the argument "pos2" but you retrieve the argument "title".
#Override
public Fragment getItem(int position) {
DetailFragment frag = new DetailFragment();
Bundle bundle = new Bundle();
bundle.putInt("fPos",position);
frag.setArguments(bundle);
return frag;
}
I am using Holoeverywhere and ViewPagerIndicator; using Holoeverywhere1 I implemented the slider and tabs in the Fragment using ViewPagerIndicator. Everything is working fine, Slider working, the menu in it, the tabs; the tabs works fine only the first time, when I move to other Fragment using the slider and come back to the tabs Fragment, the contents are no more available.
Code for the Fragment where tabs are created
public class SeconFrag extends Fragment {
ViewPager mViewPager;
FragmentAdapter mTabsAdapter;
PageIndicator mIndicator;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
mTabsAdapter = new FragmentAdapter(getSupportFragmentManager());
View view = inflater.inflate(R.layout.second_frag);
mViewPager = (ViewPager) view.findViewById(R.id.pager);
mViewPager.setAdapter(mTabsAdapter);
TitlePageIndicator indicator = (TitlePageIndicator) view
.findViewById(R.id.indicator);
indicator.setViewPager(mViewPager);
indicator.setFooterIndicatorStyle(IndicatorStyle.Triangle);
mIndicator = indicator;
return view;
}
#Override
public void onResume() {
super.onResume();
getSupportActionBar().setSubtitle("Create");
}
}
FragmentAdapter code
public class FragmentAdapter extends FragmentPagerAdapter{
protected static final String[] CONTENT = new String[] { "Choose", "Customise" };
private int mCount = CONTENT.length;
public FragmentAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
if (position == 0) {
return TabOne.newInstance();
} else if (position == 1) {
return TabTwo.newInstance();
}else if (position == 3 ) {
return TabOne.newInstance();
}else
return null;
}
#Override
public int getCount() {
return mCount;
}
#Override
public CharSequence getPageTitle(int position) {
return FragmentAdapter.CONTENT[position % CONTENT.length];
}
public void setCount(int count) {
if (count > 0 && count <= 10) {
mCount = count;
notifyDataSetChanged();
}
}
}
on of the tab Fragment
public final class TabOne extends Fragment {
public static TabOne newInstance() {
TabOne fragment = new TabOne();
return fragment;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View myFragmentView = inflater.inflate(R.layout.tab_one, container,
false);
return myFragmentView;
}
}
in the SeconFrag OnPause() I removed the Fragment no luck, hide() it in the OnPause() and tried to show() in the OnResume() still not showing content after the Fragment is changed.
EDIT
