I have created just sample application for fragment hiding and showing.At the first fragment is added into the view properly.But on menu press to hide fragment it don't get hide.I posted my code as follows..
public class SwapfragActivity extends Activity
{
FrameLayout fr;
FragmentManager fm = getFragmentManager();
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
fr = (FrameLayout) findViewById(R.id.fm1);
frag f = new frag();
}
#Override
public boolean onCreateOptionsMenu(Menu menu)
{
menu.add("SHOW");
menu.add("HIDE");
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
frag f = new frag();
if (item.getTitle() == "SHOW")
{
if (!f.isAdded())
{
FragmentTransaction ft = fm.beginTransaction();
ft.add(R.id.fm1, f);
ft.commit();
}
else if (f.isHidden())
{
FragmentTransaction ft = fm.beginTransaction();
ft.show(f);
ft.commit();
}
}
else
{
if (f.isAdded())
{
FragmentTransaction ft = fm.beginTransaction();
ft.hide(f);
ft.commit();
}
}
return true;
}
}
class frag extends Fragment
{
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
return inflater.inflate(R.layout.a, container, false);
}
}

I am working in an application where i am calling Fragment2 from Fragment1, when I am pressing default back button in Fragment2 it is taking me to Fragment1 but when I am pressing any other button and calling getActivity.finish() it is closing my Activity.
I have added the code below:
MainActivity.java
public class MainActivity extends AppCompatActivity {
AHBottomNavigation bottomNavigation;
Fragment selectedFragment = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
bottomNavigation = (AHBottomNavigation) findViewById(R.id.navigation);
AHBottomNavigationItem item1 = new AHBottomNavigationItem(R.string.home, R.drawable.home, R.color.colorAccent);
AHBottomNavigationItem item2 = new AHBottomNavigationItem(R.string.menu, R.drawable.menu, R.color.colorAccent);
AHBottomNavigationItem item3 = new AHBottomNavigationItem(R.string.cart, R.drawable.cart, R.color.colorAccent);
AHBottomNavigationItem item4 = new AHBottomNavigationItem(R.string.orders, R.drawable.orders, R.color.colorAccent);
AHBottomNavigationItem item5 = new AHBottomNavigationItem(R.string.settings, R.drawable.setting, R.color.colorAccent);
bottomNavigation.addItem(item1);
bottomNavigation.addItem(item2);
bottomNavigation.addItem(item3);
bottomNavigation.addItem(item4);
bottomNavigation.addItem(item5);
bottomNavigation.setTitleState(AHBottomNavigation.TitleState.ALWAYS_SHOW);
bottomNavigation.setAccentColor(Color.parseColor("#571e19"));
selectedFragment = ItemHomeFragment.newInstance(bottomNavigation);
bottomNavigation.setOnTabSelectedListener(new AHBottomNavigation.OnTabSelectedListener() {
#Override
public boolean onTabSelected(int position, boolean wasSelected) {
if (position == 0) {
selectedFragment = ItemHomeFragment.newInstance(bottomNavigation);
} else if (position == 4) {
selectedFragment = Fragment1 (bottomNavigation);
}
android.app.FragmentManager fragmentManager = getFragmentManager();
android.app.FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.frame_layout,selectedFragment);
fragmentTransaction.commit();
return true;
}
});
android.app.FragmentManager fragmentManager = getFragmentManager();
android.app.FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.frame_layout, ItemHomeFragment.newInstance(bottomNavigation));
fragmentTransaction.commit();
}
public void setNotification(){
bottomNavigation.setNotification("1", 1);
}
}

fragment2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
getActivity().finish();
}
});
return view;
}
}
Don't
getActivity.finish()
finish() clear the Activity.
Do
popBackStack();
Example
FragmentManager fmOBJ= getFragmentManager();
fmOBJ.popBackStack();
i have one activity which contains spinner control in appbar. in homeActivity i'm using fragment which have default fragment as parentoptionfragment, from that fragment there are 3 option to change the fragments, if i have choosen one fragment from parentoption fragment and i want to change spinner value then the fragment should be updated without adding to backstack means if i press back button then it should call parent optionfragment, but when i'm trying to do so i'm getting error.
public void GetChildData(String token) {
ParentOptionsFragment fragment =new ParentOptionsFragment();
FragmentManager fm = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fm.beginTransaction();
fragmentTransaction.replace(R.id.fragment_container, fragment);
fragmentTransaction.commit();
}
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
tv_childClassname.setText(classNameArr[position]);
tv_childSchoolName.setText(schoolNameArr[position]);
Fragment f = getSupportFragmentManager().findFragmentById(R.id.fragment_container);
if (f instanceof ChildMapFragment){
Toast.makeText(HomeActivity.this, "refreshing childmapfragment", Toast.LENGTH_SHORT).show();
ChildMapFragment fragment = new ChildMapFragment();
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.popBackStackImmediate (fragment.getClass().getName(), 0);
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.fragment_container, fragment);
fragmentTransaction.commit();
}else if(f instanceof ParentOptionsFragment){
Toast.makeText(HomeActivity.this, "spinner changed from ParentOptionsFragment", Toast.LENGTH_SHORT).show();
}
}
parentoptionfragment.java

public class ChildFragment extends Fragment {

return inflater.inflate(R.layout.fragment_child_map, container, false);
}
}
homeActivity ---> defaultfragment-- parentoptionfragment
parentoptiofragment---> childfragment
using spinner update childfragment without backstack
onbackpress of childfragment --> parentoptionfragment
replace
Toast.makeText(HomeActivity.this, "refreshing childmapfragment", Toast.LENGTH_SHORT).show();
ChildMapFragment fragment = new ChildMapFragment();
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.popBackStackImmediate (fragment.getClass().getName(), 0);
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.fragment_container, fragment);
fragmentTransaction.commit();
with :
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.popBackStack()
update :
on your child fragment add a method : update() and call it :
FragmentManager fragmentManager = getSupportFragmentManager();
Fragment fragment = fragmentManager.findFragmentById(R.id.fragment_container)
if(fragment isInstanceOf ChildMapFragment ){
((ChildMapFragment )fragment).update() //call your update method here
}
FragmentManager fragmentManager = getSupportFragmentManager();
// String f_name=fragment.getClass().getName();
if (!fragmentManager.popBackStackImmediate(tag, 0)) {
FragmentTransaction ft = fragmentManager.beginTransaction();
ft.replace(R.id.content_frame, fragment, tag);
ft.addToBackStack(tag);
ft.commit();
}
to Refresh fragment implement back stack in activity like this
#Override
public void onBackStackChanged() {
FragmentManager fragmentManager = getSupportFragmentManager();
Fragment fr = fragmentManager.findFragmentById(R.id.content_frame);
if (fr != null) {
fr.onResume();
}
}
here pass different tag base on different fragment
i need to start a fragment from another fragment.
i have my MainActivity
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
mNavigationView = (NavigationView) findViewById(R.id.shitstuff) ;
mFragmentManager = getSupportFragmentManager();
mFragmentTransaction = mFragmentManager.beginTransaction();
mFragmentTransaction.replace(R.id.containerView,new TabFragment()).commit();
mNavigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
mDrawerLayout.closeDrawers();
//Selecao dos menus
if (menuItem.getItemId() == R.id.nav_reservas) {
FragmentTransaction fragmentTransaction = mFragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.containerView, new Reservas()).commit();
} else if (menuItem.getItemId() == R.id.nav_hotel) {
FragmentTransaction xfragmentTransaction = mFragmentManager.beginTransaction();
xfragmentTransaction.replace(R.id.containerView, new TabFragment()).commit();
} else if (menuItem.getItemId() == R.id.nav_check) {
FragmentTransaction xfragmentTransaction = mFragmentManager.beginTransaction();
xfragmentTransaction.replace(R.id.containerView, new CheckIn()).commit();
} else if (menuItem.getItemId() == R.id.nav_loc) {
FragmentTransaction xfragmentTransaction = mFragmentManager.beginTransaction();
xfragmentTransaction.replace(R.id.containerView, new Endereco()).commit();
} else if (menuItem.getItemId() == R.id.nav_avalie) {
FragmentTransaction xfragmentTransaction = mFragmentManager.beginTransaction();
xfragmentTransaction.replace(R.id.containerView, new Avalie()).commit();
} else if (menuItem.getItemId() == R.id.nav_info) {
FragmentTransaction xfragmentTransaction = mFragmentManager.beginTransaction();
xfragmentTransaction.replace(R.id.containerView, new Informacoes()).commit();
} else if (menuItem.getItemId() == R.id.nav_guia) {
FragmentTransaction xfragmentTransaction = mFragmentManager.beginTransaction();
xfragmentTransaction.replace(R.id.containerView, new GuiaDaCidade()).commit();
}
return false;
}
}
);
and i start the GuiaDaCidade extends fragment.
public class GuiaDaCidade extends Fragment {
View rootView;
#Nullable
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
rootView = inflater.inflate(R.layout.guia_da_cidade, null);
View botaoPasseios = (View) rootView.findViewById(R.id.btpasseios);
View botaoAgenda = (View) rootView.findViewById(R.id.btagenda);
botaoPasseios.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
}
});
I need that when the button is clicked start the Passeios extends Fragment
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
rootView = inflater.inflate(R.layout.guia_passeios, null);
expListView = (ExpandableListView) rootView.findViewById(R.id.listaexp);
prepareListData();
listAdapter = new ExpandableListAdapter(getActivity(), listDataHeader, listDataChild);
expListView.setAdapter(listAdapter);
expandeAll();
expListView.setOnChildClickListener(new ExpandableListView.OnChildClickListener() {
#Override
public boolean onChildClick(ExpandableListView parent, View v,
int groupPosition, int childPosition, long id) {
mudaTela(groupPosition, childPosition);
return false;
}
});
return rootView;
}
I already tried everything possible but no way is working.
before you start another fragment, if you want to keep your current fragment into backstack so that it is available when user presses back button, add it to back stack using fragment manager. Then just use the same line: fragmentTransaction.replace(containerView,new Fragment(), TAG).commit();
GuiaDaCidade
botaoPasseios.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Passeios fragment = new Passeios();
FragmentTransaction transaction = getFragmentManager().beginTransaction();
transaction.replace(R.id.your_guiadacidade_layoutID, fragment);
transaction.addToBackStack(null);
transaction.commit();
}
});
I wanna inflate some fragment from an activity (which is not main but is activity).
I do exactly like this instruction:
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction =
fragmentManager.beginTransaction();
YourFragment fragment = new YourFragment();
fragmentTransaction.replace(android.R.id.content, fragment);//here is the error
fragmentTransaction.commit();
but in the one before last line, editor shows error saying:
2nd argument wrong type.Found:max.mzf.max.fragment.Required:android.app.fragment
this is my own code:
Activity
public class QuizCard extends FragmentActivity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.quiz_card);
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
QcardFragment fragment = new QcardFragment();
fragmentTransaction.replace(R.id.your_placeholder, fragment );
fragmentTransaction.commit();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.card_menu, menu);
return true;
}
and this is QcardFragment:
public class QcardFragment extends Fragment {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//get data from Argument
}
public void onCardClick(View view) {
flipCard();
}
private void flipCard() {
View rootLayout = (View) getActivity().findViewById(R.id.main_activity_root);
View cardFace = (View) getActivity().findViewById(R.id.main_activity_card_face);
View cardBack = (View) getActivity().findViewById(R.id.main_activity_card_back);
FlipAnimation flipAnimation = new FlipAnimation(cardFace, cardBack);
if (cardFace.getVisibility() == View.GONE) {
flipAnimation.reverse();
}
rootLayout.startAnimation(flipAnimation);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.qcardfragment, container, false);
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
}
}
What's wrong?
Make sure that your fragment class extends Fragment from android native library. If you are using external implementation try to change
FragmentManager fragmentManager = getFragmentManager();
to
FragmentManager fragmentManager = getSupportFragmentManager();
My code was working few hours ago but not anymore, I can't see what is the reason.
Here is my listener where I change fragment after a click :
CustomMarkRow.java
public void onClick(DialogInterface dialogInterface, int i){
Bundle bundle = new Bundle();
bundle.putInt("id", CustomMarkRow.this.mark.getId());
FragmentManager fragmentManager = CustomMarkRow.this.fragmentManager;
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction(); activity.getActionBar().setSelectedNavigationItem(CustomMarkRow.this.positionTab);
EditMarkFragment fragment = new EditMarkFragment();
fragment.setArguments(bundle);
fragmentTransaction.replace(R.id.fragmentContainer, fragment,"2");
fragmentTransaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
}
At this moment, fragment.getArguments() contains what I put inside :
{android.os.Bundle#3644} "Bundle[{id=1}]"
In my second file :
EditMarkFragment.java
public class EditMarkFragment extends Fragment {
public View view;
public EditMarkFragment(){
super();
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
this.view = inflater.inflate(getResources().getIdentifier("edit_mark", "layout",container.getContext().getPackageName()), container, false);
if(this.getArguments()==null){ // always null
...
}
return this.view
}
getArguments() always return null here, What is bad in this sample ?
* edit *
Here is my launcher class :
public class Launcher extends Activity implements ActionBar.TabListener {
private HomeFragment frag1 = new HomeFragment();
private EditMarkFragment frag2 = new EditMarkFragment();
private MarkListFragment frag3 = new MarkListFragment();
private EditCategoryFragment frag4 = new EditCategoryFragment();
private CategoryListFragment frag5 = new CategoryListFragment();
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().requestFeature(Window.FEATURE_ACTION_BAR);
setContentView(R.layout.launcher);
//Configuration de la barre d'onglet
getActionBar().setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
ActionBar.Tab tab1 = getActionBar().newTab().setTabListener(this).setTag("1").setText("Home"); //.setIcon(R.drawable.homew);
getActionBar().addTab(tab1);
ActionBar.Tab tab2 = getActionBar().newTab().setTabListener(this).setTag("2").setText("New Mark"); //.setIcon(R.drawable.addw);
getActionBar().addTab(tab2);
ActionBar.Tab tab3 = getActionBar().newTab().setTabListener(this).setTag("3").setText("My Marks"); //.setIcon(R.drawable.listw);
getActionBar().addTab(tab3);
ActionBar.Tab tab4 = getActionBar().newTab().setTabListener(this).setTag("4").setText("New Category"); //.setIcon(R.drawable.categoryw);
getActionBar().addTab(tab4);
ActionBar.Tab tab5 = getActionBar().newTab().setTabListener(this).setTag("5").setText("Categories"); //.setIcon(R.drawable.categoryw);
getActionBar().addTab(tab5);
}
#Override
public void onTabSelected(ActionBar.Tab tab, android.app.FragmentTransaction ft) {
if(tab.getTag().equals("1")){
ft.replace(R.id.fragmentContainer, frag1);
}
else if(tab.getTag().equals("2")){
ft.replace(R.id.fragmentContainer, frag2);
}
else if(tab.getTag().equals("3")){
ft.replace(R.id.fragmentContainer, frag3);
}
else if(tab.getTag().equals("4")){
ft.replace(R.id.fragmentContainer, frag4);
}
else if(tab.getTag().equals("5")){
ft.replace(R.id.fragmentContainer, frag5);
}
}
#Override
public void onTabUnselected(ActionBar.Tab tab, android.app.FragmentTransaction ft) {
if(tab.getTag().equals("1")){
ft.remove(frag1);
}
else if(tab.getTag().equals("2")){
ft.remove(frag2);
}
else if(tab.getTag().equals("3")){
ft.remove(frag3);
} else if(tab.getTag().equals("4")){
ft.remove(frag4);
}
else if(tab.getTag().equals("5")){
ft.remove(frag5);
}
}
#Override
public void onTabReselected(ActionBar.Tab tab, android.app.FragmentTransaction ft) {
}
}
While your onClick() code is creating an arguments Bundle, your onCreate() is not. If that edition of your fragment calls getArguments(), the method will return null.
1-Update your EditMark fragment with as follows:-
public class EditMarkFragment extends Fragment {
public static View view;
public static EditMarkFragment newInstance(int id) {
EditMarkFragment fragment = new EditMarkFragment();
Bundle bundle = new Bundle();
bundle.putInt("id", id);
fragment.setArguments(bundle);
return fragment;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
this.view = inflater.inflate(getResources().getIdentifier("edit_mark", "layout",container.getContext().getPackageName()), container, false);
int id=getArguments.getInt("id");
return this.view}
2- Inside CustomMarkRow update your code as :-
public void onClick(DialogInterface dialogInterface, int i){
FragmentManager fragmentManager = CustomMarkRow.this.fragmentManager;
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction(); activity.getActionBar().setSelectedNavigationItem(CustomMarkRow.this.positionTab);
EditMarkFragment fragment = EditMarkFragment.newInstance(CustomMarkRow.this.mark.getId()) ;
fragmentTransaction.replace(R.id.fragmentContainer, fragment,"2");
fragmentTransaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
}
Try this,hope this will hep you.
