I have on activity (MainActivity) and it has five tabs, each tab contains a fragment. Each fragment contains an EditText widget. I'd like to set the active tab's title when I change the text of the EditText in the active fragment's class. How could I do that on the fly ?
Here are my resources:
MainActivity:
public class MainActivity extends AppCompatActivity {
private SectionsPagerAdapter mSectionsPagerAdapter;
private ViewPager mViewPager;
ImageView imageView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
mViewPager = (ViewPager) findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(mViewPager);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
SectionPagerAdapter:
public class SectionsPagerAdapter extends FragmentPagerAdapter {
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
switch (position){
case 0:
Tab1 tab1 = new Tab1();
return tab1;
case 1:
Tab2 tab2 = new Tab2();
return tab2;
case 2:
Tab3 tab3 = new Tab3();
return tab3;
case 3:
Tab4 tab4 = new Tab4();
return tab4;
case 4:
Tab5 tab5 = new Tab5();
return tab5;
default:
return null;
}
}
#Override
public int getCount() {
// Show 5 total pages.
return 5;
}
#Override
public CharSequence getPageTitle(int position) {
switch (position) {
case 0:
return "title1";
case 1:
return "title2";
case 2:
return "title3";
case 3:
return "title4";
case 4:
return "title5";
}
return null;
}
}
Tab1:
public class Tab1 extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.tab1, container, false);
return rootView;
}
}
These are generated by Android Studio, so I guess I should go from here. What I want, if I have an EditText on the Tab1, and I start to type in it, it changes the first tab's title from "title1" to the string I typed.
From edittext you should use addTextChangedListener on EditText within that TextWatcher instance to change title on the fly. Refer this code.
editText.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
#Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
//this is your tab index you want to change title of..
tabLayout.getTabAt(1).setText(charSequence);
}
#Override
public void afterTextChanged(Editable editable) {
}
});
Hope this helps..

I am creating an application with 3 tabs. I have taken the code for a notepad-like app from here, and what I want is to put the notepad in a fragment inside a tab. I have done this but whenever I add a new note it is not reflected in the tab. I think I will have to use notifyDataSetChanged() but I am having difficulty as to where I can use it. Some help will be appreciated.
I have put a FAB in the tab. When I click it the app goes to the DisplayNote where I can enter the note title and content for the note as in the original app. I have confirmed that when I click "Save" the note is saved but the tab does not show this.
This is the relevant code for my MainActivity:
public class MainActivity extends AppCompatActivity {
private SectionsPagerAdapter mSectionsPagerAdapter;
private ViewPager mViewPager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
// 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);
}
}
This is the code for the Adapter:
class SectionsPagerAdapter extends FragmentStatePagerAdapter {
SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
#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() {
// Show 3 total pages.
return 3;
}
#Override
public CharSequence getPageTitle(int position) {
switch (position) {
case 0:
return "Tab 1";
case 1:
return "Tab 2";
case 2:
return "Notes";
default:
return null;
}
}
And this is the code for the third tab:
public class Tab3Notes extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.mynotes, container, false);
FloatingActionButton add_note;
add_note = (FloatingActionButton) rootView.findViewById(R.id.add_note_button);
add_note.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Bundle dataBundle = new Bundle();
dataBundle.putInt("id", 0);
Intent intent = new Intent(getContext(), DisplayNote.class);
intent.putExtras(dataBundle);
startActivity(intent);
}
});
return rootView;
}
}
Add this to your SectionsPagerAdapter:
#Override
public int getItemPosition(Object object) {
return POSITION_NONE;
}
Then when you call notifyDatasetChanged, the adapter will think all the pages are new and recreate them
i have a problem with changing my title. i can change the title using fragment but each time i click or change to another fragment the title is didnt change to the correct title. here is my code:
This is my main tabactivity
public class TabActivity extends AppCompatActivity {
private SectionsPagerAdapter mSectionsPagerAdapter;
private ViewPager mViewPager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_tab);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
// 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);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_tab, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
/**
* 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) {
switch (position){
case 0:
profile_menu tab1 = new profile_menu();
return tab1;
case 1:
group_menu tab2 = new group_menu();
return tab2;
case 2:
world_menu tab3 = new world_menu();
return tab3;
case 3:
prize_menu tab4 = new prize_menu();
return tab4;
default:
return null;
}
}
#Override
public int getCount() {
// Show 3 total pages.
return 4;
}
#Override
public CharSequence getPageTitle(int position) {
switch (position) {
case 0:
return "Profile ";
case 1:
return "Group ";
case 2:
return "World ";
case 3:
return "Prize";
}
return null;
}
}
public void setActionBarTitle(String title){
getSupportActionBar().setTitle(title);
}
}
and this is my fragment
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.prize_menu, container, false);
getActivity().setTitle("Prize");
return rootView;
}
I assume that you want to change the title when tab change?
mViewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
#Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
}
#Override
public void onPageSelected(int position) {
switch (position) {
case 0:
getSupportActionBar().setTitle("Profile ");
break;
case 1:
getSupportActionBar().setTitle("Group");
break;
case 2:
getSupportActionBar().setTitle("World");
break;
case 3:
getSupportActionBar().setTitle("Prize");
break;
default:
break;
}
}
#Override
public void onPageScrollStateChanged(int state) {
}
});
if (getActivity().getActionBar() != null) {
getActivity().getActionBar().setTitle("YourTitle");
}
Use this line in onViewCreated() of each fragment will solve your problem
call getActivity().setTitle("Prize"); it in onResume of each fragment
In Fragment
Set your title in simple way. Add this method in your common class.
Add your title with back arrow in action bar.
public void setPageTitle(String title) {
((AppCompatActivity) getActivity()).getSupportActionBar().setDisplayShowCustomEnabled(false);
((AppCompatActivity) getActivity()).getSupportActionBar().setDisplayHomeAsUpEnabled(true);
((AppCompatActivity) getActivity()).getSupportActionBar().setTitle(Html.fromHtml("<font color='#ffffff'>"+title+ "</font>"));
}
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstantState){
view = inflater.inflate(R.layout.fragment_name,container,false);
setPageTitle("title");
return view;
}
If you want title alone, use this line alone in your fragment onCreateView(). But this code does not handle back arrow.
((AppCompatActivity) getActivity()).getSupportActionBar().setTitle("Title");
Quick way to do:
Declare your ToolBar as static and access from the fragment:
MainActivity:
public static Toolbar mToolbar;
in your fragment:
mToolbar.setTitle("your title here");
You set the Fragment title in the mobile_navigation.xml file in res -> navigation.
Use the android:label=""
I have a Tabbed Activity with 3 Tabs. On each Tab are RecyclerViews with some list items. If you click on an item a new fragment should open and there should appear a Back-Button in the toolbar. My current screen looks like this:
And now I will show you my code. At first MainActivity.java with the TabLayout:
public class MainActivity extends AppCompatActivity {
private SectionsPagerAdapter mSectionsPagerAdapter;
private ViewPager mViewPager;
private Toolbar toolbar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar = (Toolbar) findViewById(R.id.toolbar);
toolbar.setTitle("Pflege");
setSupportActionBar(toolbar);
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
mViewPager = (ViewPager) findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(mViewPager);
tabLayout.getTabAt(0).setIcon(R.drawable.tab_icon_pflege);
tabLayout.getTabAt(1).setIcon(R.drawable.tab_icon_dokumentation);
tabLayout.getTabAt(2).setIcon(R.drawable.tab_icon_probleme);
tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
#Override
public void onTabSelected(TabLayout.Tab tab) {
switch(tab.getPosition()) {
case 0:
mViewPager.setCurrentItem(0);
toolbar.setTitle("Pflege");
break;
case 1:
mViewPager.setCurrentItem(1);
toolbar.setTitle("Daten");
break;
case 2:
mViewPager.setCurrentItem(2);
toolbar.setTitle("Probleme");
break;
default:
mViewPager.setCurrentItem(tab.getPosition());
toolbar.setTitle("Pflege");
break;
}
}
#Override
public void onTabUnselected(TabLayout.Tab tab) {
}
#Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
public class SectionsPagerAdapter extends FragmentPagerAdapter {
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
switch(position){
case 0:
Tab1Pflege tab1 = new Tab1Pflege();
return tab1;
case 1:
Tab2Dokumentation tab2 = new Tab2Dokumentation();
return tab2;
case 2:
Tab3Probleme tab3 = new Tab3Probleme();
return tab3;
default:
return null;
}
}
#Override
public int getCount() {
// Show 3 total pages.
return 3;
}
#Override
public CharSequence getPageTitle(int position) {
switch (position) {
case 0:
return "Pflege";
case 1:
return "Daten";
case 2:
return "Probleme";
}
return null;
}
}
}
Here is the Fragment for the first tab with the RecyclerView:
public class Tab1Pflege extends Fragment {
private RecyclerView recyclerView;
private RecyclerView.Adapter rvAdapter;
private RecyclerView.LayoutManager rvLayoutManager;
private ArrayList<String> listItems;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.tab1_pflege, container, false);
listItems = new ArrayList<>();
listItems.add("Test1");
listItems.add("Test2");
listItems.add("Test3");
recyclerView = (RecyclerView) rootView.findViewById(R.id.recyclerView);
rvLayoutManager = new LinearLayoutManager(getActivity());
recyclerView.setLayoutManager(rvLayoutManager);
rvAdapter = new RvAdapter(listItems);
recyclerView.setAdapter(rvAdapter);
return rootView;
}
}
And here is my RecyclerView Adapter:
public class RvAdapter extends RecyclerView.Adapter<RvAdapter.MyViewHolder> {
ArrayList<String> listItems;
public RvAdapter (ArrayList<String> listItems){
this.listItems = listItems;
}
#Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.rv_item_layout, null);
return new MyViewHolder(itemView);
}
#Override
public void onBindViewHolder(MyViewHolder holder, final int position) {
holder.itemTitle.setText(listItems.get(position));
holder.itemImage.setImageResource(R.drawable.ic_keyboard_arrow_right);
holder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
System.out.println(listItems.get(position));
}
});
}
#Override
public int getItemCount() {
return listItems.size();
}
public class MyViewHolder extends RecyclerView.ViewHolder{
TextView itemTitle;
ImageView itemImage;
public MyViewHolder(View itemView){
super(itemView);
itemTitle = (TextView) itemView.findViewById(R.id.itemTitle);
itemImage = (ImageView) itemView.findViewById(R.id.itemImage);
}
}
}
In this class is an onClickListener for clicking on a list item. And there I want to open a new fragment for example for Test1. On top of that there should appear a Back-Button in the toolbar to navigate back to the Tab1 Overview with the RecyclerView. But I have no idea how to do that. Can someone help me with it?
In onClick, you can do something like this (to load another fragment)
FragmentTransaction trans = getSupportFragmentManager().beginTransaction();
Fragment fragment = // TODO: initialise your fragment 'fragment'
mFragments.push(fragment);
// Animation, if need it
// trans.setCustomAnimations(R.anim.right_in, R.anim.left_out,
// R.anim.right_out, R.anim.left_in);
// _container is the id of 'fragment' container in the your xml
trans.replace(R.id._container, fragment);
// variable to identify this fragment, and title of the page as well
String name = // TODO: initialise
trans.addToBackStack(name);
trans.commit();
getSupportActionBar().setTitle(name);
and in onCreate of your activity, setup listener for back stack changes.
FragmentManager manager = getSupportFragmentManager();
manager.addOnBackStackChangedListener(mBackStackListener);
and you can change back icon in
private OnBackStackChangedListener mBackStackListener = new OnBackStackChangedListener() {
#Override
public void onBackStackChanged() {
FragmentManager manager = getSupportFragmentManager();
int count = manager.getBackStackEntryCount();
if(count > 0) {
// TODO: Show back icon
} else {
// TODO: Other icon
}
}
};
On tab, I have attached five fragments.Till 3rd fragment navigation is fine but when going to 4th and 5th fragment directly or by swiping, app is getting crashed.
This is my main activity.

Case 4 is missing in your adapter. Add the Case 4 instead of 5 then it will work fine.

There are 2 problems with your code:
The final View v in the onCreateView is shadowed by the View v being passed as an argument of the onClick method.
You need to setup pager before you can use it. At present, you are setting it up in the onClick method. You need to move the pager setup code to the onCreateView method.
