in my class I'm calling another class to diplay fragment in dialog
public class FragmentT extends Fragment implements AnimationListener {
ImageButton btn;
Context cxt;
RelativeLayout fragmentT;
View vPOp;
Animation animation;
ViewPager pager;
#Override
public View onCreateView(final LayoutInflater inflater, final ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
if (container == null) {
return null;
}
cxt=getActivity();
this.activity=getActivity();
vPOp = inflater.inflate(R.layout.pop, container, false);
pager = (ViewPager) vPOp.findViewById(R.id.up);
btn = (ImageButton) vPop.findViewById(R.id.button);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
new DialogFragmentWindow().show(getSupportFragmentManager(),"");
}
});
return vPop;
}
#Override
public void onAnimationEnd(Animation arg0) {
// TODO Auto-generated method stub
}
#Override
public void onAnimationRepeat(Animation arg0) {
// TODO Auto-generated method stub
}
#Override
public void onAnimationStart(Animation arg0) {
// TODO Auto-generated method stub
}
}
where DialogFragmentWindow is
public class DialogFragmentWindow extends DialogFragment {
PageAdapter pPageAdapter;
Context context;
ViewPager vp;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.pop, container);
context = getActivity();
// this.activity=getActivity();
vp = (ViewPager) view.findViewById(R.id.pVF);
List<Fragment> fragments = getFragments();
FragmentAdapter pA = new FragmentAdapter(getChildFragmentManager(),fragments);
vp.setAdapter(pA);
getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);
return view;
}
private List getFragments() {
List<Fragment> fragmentPop = new Vector<Fragment>();
//fragmentPop.add(FragSc1.newInstance());
fragmentPop.add(Fragment.instantiate(context,
FragSc1.class.getName()));
fragmentPop.add(Fragment.instantiate(context,
FragSc2.class.getName()));
return fragmentPop;
}
}
so the problem is,neither do DialogFragmentWindow is accepting the argument getChildFragmentManager(),nor do the FragmentT class is taking,
new DialogFragmentWindow().show(getSupportFragmentManager(), "");
the viewpager i'm calling is in another layout so want to use getChildFragmentManager(),not able understand thwe prob,using chid fragment/viewpager for the first time.
Just try to do as like this. It may help you.
new DialogFragmentWindow().show(getSupportFragmentManager().beginTransaction(), "dialog");

I have navigational drawer and fragment for each drawer item. Now Under each fragment we have created multiple fragments using FragmentPagerAdapter.
I've 3 drawer items as Home, Group and Feedback. Under Home, there are 2 fragments i.e My Profile and Logged
so i've created a swipeable tabs for My Profile and Logged and these two fragments are under home item. Now i've to do some network calls in both the fragments(My Profile, Logged) but how to identify which fragment is active on FragmentPagerAdapter? Is it possible to stop adapter to create fragments in advance.
HomeFragment
DrawerModel model = new DrawerModel();
LoggedFragment loggedFrag = new LoggedFragment();
loggedFrag.setTargetFragment(loggedFrag, 0);
model.setFragment(loggedFrag);
dFragments.add(model);
model = new DrawerModel();
model.setDrawerTitle(getString(R.string.profile_tab_title));
model.setFragment(new ProfileFragment());
dFragments.add(model);
Bundle bundle = new Bundle();
bundle.putSerializable("fragments", dFragments);
fragment = new DrawerFragment();
fragment.setArguments(bundle);
navigateFragment(fragment);

Call to update fragment method
Fragment fragment = activity.getSupportFragmentManager()
.findFragmentById(R.id.content_frame)
.getTargetFragment();
if (fragment instanceof LoggedFragment) {
LoggedFragment logged = (LoggedFragment) fragment;
logged.updateBanner(result, parameter[1]);
} else
Log.d(TAG, "No Logged Fragment Found");
Now under logged and my profile fragment i need to fetch some data dynamically as soon fragment is visible to user but unable to do so?
Any ideas/suggestions is highly appreciated.
use below code to find your fragment,
FragmentAdapter pa = (FragmentAdapter)viewPager.getAdapter();
pa.getFragment(viewPager.getCurrentItem()).updateBanner();
the code select current visible fragment you can change it to other one by
pa.getFragment(index of other fragment).updateBanner();
you must cast pa.getFragment(viewPager.getCurrentItem()) to what fragment you want for example if at that position it is logged change it to below:
((LoggedFragment)pa.getFragment(viewPager.getCurrentItem()) )
I would say you have two differnt options.
Option one: Use setTargetFragment() and getTargetFragment() so you get a reference to that fragment you need.
Option two: Use the FragmentManager simply get that Fragment you need from the FragmentManager and call that methods you defined on your Fragment.
Hi I have a Swipe Tab Fragment Activity that contains Three Fragments. I created my own adapter that extends FragmentStatePageAdapter.
Now here I'll explain how each tab (Fragments) works.
In Tab 1 and Tab 2, I have a list with practically the same type, when I mean type, I mean they are Symptoms (fever, pain in the eyes, etc.).
Now Tab 3 serves as a tray. Whenever I select an item from the listview in either Tab 1 or Tab 2, I want to transfer that item to Tab 3 and remove that Item from the List where it was selected.
I have tried implementing an Interface but it didn't work for me since I added the fragments on the Main FragmentActivity through an Adapter. MY questions is
How can I communicate the three Fragments? Meaning how can I pass data between these fragment.
Now if you want to take a look at what I've done for now, here it is:
I depicted this as Tab 2 in my question
public class FragmentGeneralSymptoms extends ListFragment implements OnItemClickListener {
ArrayList<String> symptomList;
String name;
String selected;
Tray tray;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
return inflater.inflate(R.layout.fragment_generalsymptoms, container,
false);
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onActivityCreated(savedInstanceState);
Bundle args = getArguments();
name = args.getString("key");
tray = (Tray) getActivity();
new LoadSymptoms().execute();
}
class LoadSymptoms extends AsyncTask<String, String, String> {
#Override
protected String doInBackground(String... params) {
// TODO Auto-generated method stub
KnowledgeBaseHelper helper = new KnowledgeBaseHelper(getActivity());
ProfileHandler handler = new ProfileHandler(getActivity());
Profiles profile = handler.getProfile(name);
String age = profile.getAge() + "";
String gender = profile.getGender();
symptomList = helper.getSymptomList(name, age, gender);
return null;
}
#Override
protected void onPostExecute(String result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
setListAdapter(new ArrayAdapter<String>(getActivity(),
R.layout.general_list, symptomList));
}
}
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
// TODO Auto-generated method stub
selected = symptomList.get(arg2);
tray.respond(selected);
}
}
My Tab 3
public class FragmentTray extends ListFragment{
private ArrayList<String> selectedList;
public FragmentTray(){}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
return inflater.inflate(R.layout.fragment_tray, container, false);
}
public void addToTray(String symptom){
selectedList.add(symptom);
setListAdapter(new ArrayAdapter<String>(getActivity(),
R.layout.general_list, selectedList));
}
public void removeSymptom(String string){
selectedList.remove(selectedList.indexOf(string));
}
}
My MainActivity which Extends FragmentActivity
public class MainActivity extends FragmentActivity implements TabListener, OnPageChangeListener, Tray {
private String selectedProfileName;
ActionBar actionBar;
ViewPager viewPager;
#Override
protected void onCreate(Bundle arg0) {
// TODO Auto-generated method stub
super.onCreate(arg0);
setContentView(R.layout.main_activity);
Bundle args = getIntent().getExtras();
selectedProfileName = args.getString("key_name");
viewPager = (ViewPager) findViewById(R.id.main_pager);
viewPager.setAdapter(new MyAdapter(getSupportFragmentManager()));
viewPager.setOnPageChangeListener(this);
InitializeActionBar();
}
public void InitializeActionBar() {
actionBar = getActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
ActionBar.Tab tabBodyPart = actionBar.newTab();
tabBodyPart.setText("Body Parts");
tabBodyPart.setTabListener(MainActivity.this);
ActionBar.Tab tabGeneralSymptoms = actionBar.newTab();
tabGeneralSymptoms.setText("General Symptoms");
tabGeneralSymptoms.setTabListener(MainActivity.this);
ActionBar.Tab tabSelectedSymptoms = actionBar.newTab();
tabSelectedSymptoms.setText("Selected Symptoms");
tabSelectedSymptoms.setTabListener(MainActivity.this);
actionBar.addTab(tabBodyPart);
actionBar.addTab(tabGeneralSymptoms);
actionBar.addTab(tabSelectedSymptoms);
}
#Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
// TODO Auto-generated method stub
viewPager.setCurrentItem(tab.getPosition());
}
class MyAdapter extends FragmentStatePagerAdapter {
public MyAdapter(FragmentManager fm) {
super(fm);
// TODO Auto-generated constructor stub
}
#Override
public Fragment getItem(int arg0) {
// TODO Auto-generated method stub
Fragment fragment = null;
Bundle bundle = new Bundle();
bundle.putString("key", selectedProfileName);
if (arg0 == 0) {
fragment = new FragmentBodyPart();
fragment.setArguments(bundle);
}
if (arg0 == 1) {
fragment = new FragmentGeneralSymptoms();
fragment.setArguments(bundle);
}
if (arg0 == 2) {
fragment = new FragmentTray();
}
return fragment;
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return 3;
}
}
#Override
public void onPageSelected(int arg0) {
// TODO Auto-generated method stub
actionBar.setSelectedNavigationItem(arg0);
}
#Override
public void respond(String string) {
// TODO Auto-generated method stub
FragmentTray frag2 = new FragmentTray();
frag2.addToTray(string);
}
}
Finally my Interface
public interface Tray {
public void respond(String string);
}
what I usually do is:
1.- Define the interface. It's done, fine.
2.- Your FragmentGeneralSymptoms must have an initializated listener. Yuou're that but you forgot to set the listener in the class.
public class FragmentGeneralSymptoms extends ListFragment implements OnItemClickListener {
ArrayList<String> symptomList;
String name;
String selected;
Tray tray;
(your code)
public void setTrayListener(Tray listener)
{
tray = listener;
}
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
// TODO Auto-generated method stub
selected = symptomList.get(arg2);
if(tray != null)
{
symptomList.remove(selected); // if you want to remove this element from this list
tray.respond(selected);
}
} }
3.- Your FragmentTray class must implement the interface:
public class FragmentTray extends ListFragment implements Tray{
private ArrayList<String> selectedList;
public FragmentTray(){}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
return inflater.inflate(R.layout.fragment_tray, container, false);
}
public void addToTray(String symptom){
selectedList.add(symptom);
setListAdapter(new ArrayAdapter<String>(getActivity(),
R.layout.general_list, selectedList));
}
public void removeSymptom(String string){
selectedList.remove(selectedList.indexOf(string));
}
public void respond(String name)
{
// do stuffs!!!!
selectedList.add(new Symtom(name)); // for example
System.out.println("Inside the respond method respond in FragmentTray class");
}
}
4.- And last but not least. When you build the fragments you must register the listener:
class MyAdapter extends FragmentStatePagerAdapter {
private List<Fragment> fragmentList;
public MyAdapter(FragmentManager fm) {
super(fm);
// TODO Auto-generated constructor stub
fragmentList = new ArrayList<Fragment>();
Fragment fragmentBodyPart = new FragmentBodyPart();
Fragment fragmentTray = new FragmentTray();
Fragment fragmentGeneralSymptoms = new FragmentGeneraSymptoms();
// this is important*********************************
fragmentGeneraSmptoms.setTrayListener(fragmentTray);
fragmentList.add(fragmentBodyPart);
fragmentList.add(fragmentGeneralSymptoms);
fragmentList.add(fragmentTray);
}
#Override
public Fragment getItem(int arg0) {
// TODO Auto-generated method stub
Fragment fragment = null;
Bundle bundle = new Bundle();
bundle.putString("key", selectedProfileName);
if (arg0 == 0) {
fragment = (Fragment) fragmentList.get(0);
fragment.setArguments(bundle);
}
if (arg0 == 1) {
fragment = (Fragment) fragmentList.get(1);
fragment.setArguments(bundle);
}
if (arg0 == 2) {
fragment = (Fragment) fragmentList.get(2);
}
return fragment;
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return fragmentList.size();
}
}
I hope that it helps.
i had create 3 tab with view pager. There is an issue is that in all 3 tab i had save and exit button but when i swipe page one two time and pres on save or exit button it will not work becuse when move to second fragment if call third fragment view.

when i try to access the eddittext inside pageZero class like below
name=(EditText)view.findViewById(R.id.nameTV);
a=name.getText().toString().trim();
i am getting null value.help me out..Thanks in advance.
Change the pagezero class oncreateview code like this .....
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view =getActivity().getLayoutInflater().inflate(R.layout.componentname,null);
name=(EditText)view.findViewById(R.id.nameTV);
name.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
a=name.getText().toString().trim();
Toast.makeText(getApplicationContext(),a,Toast.LENGTH_SHORT).show();
}
return view;
});
Return the view friend and then use default layout inflater...
At the time you click the edittext field, is there any content? Maybe you should get the text in the lost focus event of the edittext field. Thus you can enter some text first...
Example:
name.setOnFocusChangeListener(new OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if(hasFocus == false){
//get text from edittext field...
}
}
});
The way you try to get the text looks right to me. At least I do it the same way.
In the PagerAdapter's 'getItem' Method you should instantiate your fragments directly:
#Override
public Fragment getItem(int position) {
switch (position) {
case 0:
return new PageZero();
case 1:
return new PageOne();
case 2:
return new PageTwo();
}
return null;
}
The Viewpager only calls getItem if it wants to create a new item. Unfortunatly they called the method getItem and not createItem which would be more obvious.
Get your EditText inside onClick block...
This mean change the code from:
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.componentname, container, false);
name=(EditText)view.findViewById(R.id.nameTV);
name.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
a=name.getText().toString().trim();
Toast.makeText(getApplicationContext(),a,Toast.LENGTH_SHORT).show();
}
});
return view;
}
To:
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.componentname, container, false);
name.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// GET EDIT TEXT HEAR:
EditText name=(EditText)view.findViewById(R.id.nameTV);
a=name.getText().toString().trim();
Toast.makeText(getApplicationContext(),a,Toast.LENGTH_SHORT).show();
}
});
return view;
}
To create a 3 different fragments with view pager you should:
1)Create FragmentActivity with view pager and view pager adapter.
public class FragmentActivity extends FragmentActivity
{
private FragmentAdapter adapter;
private ViewPager pager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_fragment);
adapter = new FragmentAdapter(getSupportFragmentManager());
pager = (ViewPager) findViewById(R.id.pager);
pager.setAdapter(adapter);
}
2)Create 3 Fragments with static instance
public final class Fragment1 extends Fragment
{
public static Fragment1 newInstance() {
return new Fragment1();
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
LinearLayout layout = new LinearLayout(getActivity());
// your fragment xml view
return view;
}
}
3)Fill view pager adapter with it;
public class FragmentAdapter extends FragmentPagerAdapter
{
public InstallFragmentAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
switch (position) {
case 0:
return Fragment1.newInstance();
case 1:
return Fragment2.newInstance();
case 2:
return Fragment3.newInstance();
}
return null;
}
}
public class PageZero extends Fragment {
public static EditText name; //change this to public static
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.componentname, container,
false);
name = (EditText)view.findViewById(R.id.nameTV);
name.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
}
});
return view;
}
}
Then, you can access the public static EditText name (after the view for it has been generated of course) from another fragment like this.
public class PageOne extends Fragment {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.componentaddress, container,
false);
EditText page_one_text = PageZero.name; //you can get that variable in any fragment now, but using the class name of that fragment to access it
return view;
}
}
Cheers. Please mark this as the correct answer if it helps you. You have quite a bit of answers here
I tried below code. Working for me
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_main_explore, container, false);
ed1 = (EditText)v.findViewById(R.id.editTextTemp);
if( ed1 == null )
{
Toast.makeText(getActivity(), "ERROR UNABLE TO GET EDIT", Toast.LENGTH_LONG).show();
}
// Inflate the layout for this fragment
//return inflater.inflate(R.layout.fragment_main_explore, container, false);
return v;
}
MainActivity.java
public class MainActivity extends SherlockFragmentActivity {
static MyListfragment mf;
ViewPager mpager;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
mf = new MyListfragment();
ft.add(android.R.id.content,mf).commit();
}}
MyListfragment.java
public class MyListfragment extends SherlockListFragment {
MyDisplayfragment tempFrag;
#Override
public void onListItemClick(ListView l, View v, int position, long id) {
// TODO Auto-generated method stub
super.onListItemClick(l, v, position, id);
Connector.selection = position;
FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();
if(position==0)
{
tempFrag=new MyDisplayfragment();
tempFrag.setLayout(R.layout.law);
subFragmentAdapter mAdapter = new subFragmentAdapter(getChildFragmentManager());
tempFrag.setViewPagerAdapter(mAdapter);
}
ft.replace(android.R.id.content,tempFrag);
ft.addToBackStack(null);
ft.commit();
}
#Override
public void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
int layout = Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB ?
android.R.layout.simple_list_item_activated_1 : android.R.layout.simple_list_item_1;
setListAdapter(new ArrayAdapter<String>(getActivity(),
layout, Connector.list));
}}
MyDisplayfragment.java
public class MyDisplayfragment extends SherlockFragment {
int resource;
FragmentPagerAdapter mAdapter;
ViewPager v;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
if(Connector.selection==-1)
resource=R.layout.displayfragment;
return inflater.inflate(resource, container, false);
}
public void setViewPagerAdapter(FragmentPagerAdapter x)
{
mAdapter=x;
}
public void setLayout(int layout)
{
resource=layout;
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onViewCreated(view, savedInstanceState);
ViewPager pager=(ViewPager) view.findViewById(R.id.mpager);
pager.setAdapter(mAdapter);
}}
subFragment.java
public final class subFragment extends SherlockFragment {
private int layout;
public static subFragment newInstance(int content) {
subFragment fragment = new subFragment();
fragment.layout=content;
return fragment;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
return inflater.inflate(layout,container,false);
}}
subFragmentAdapter.java
public class subFragmentAdapter extends FragmentPagerAdapter{
int[] LAYOUT={R.layout.cccc,R.layout.aaaa,R.layout.bbb};
private int mCount;
public subFragmentAdapter(FragmentManager fm) {
super(fm);
mCount = LAYOUT.length;
}
#Override
public Fragment getItem(int position) {
return subFragment.newInstance(LAYOUT[position]);
}
#Override
public int getCount() {
return mCount;
}
}
Connector.java
public class Connector {
static int selection = -1;
static String list[] = { "Law" };}
In the above project
1)MyListfragment.java is used for navigation
2)MyDisplayfragment.java is used to display according to selection made in MyListFragment
3)Connector.java is used to communicate between the above two fragments
4)subFragment.java is used to populate Viewpager with Fragments
5)subFragmentAdapter.java is th adapter for Viewpager
When i run this project the viewpager seems to be blank and doesnot show any of the child fragments and after debugging i saw that onCreateView() method of subFragment.java is not called.
My question is why the onCreateView() method is not being called
Please refer to Luksprog's comment for the answer.
