I am trying a simple interaction between two fragments in Tabbed activity.
I have a two layouts with TextView, EditText and Button. I am trying to achieve move text from EditText in FragmentOne to the EdidText (or TextView) in Fragment two when the Button from FragmentOne is pressed. But it doesnt works.
During debuging there isnt any problem. App doesnt stop working.
Is something problem in ViewPager or SectionsPagerAdapter?
I have this two fragments.
Fragments One:
public class FragmentOne extends Fragment {
TextView textView;
EditText editText;
Button button;
private OnFragmentOneInteractionListener mListener;
public FragmentOne()
{
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
View view = inflater.inflate(R.layout.fragment_one, container, false);
editText = (EditText) view.findViewById(R.id.fragOne_txb);
textView = (TextView) view.findViewById(R.id.fragTwo_header);
button = (Button) view.findViewById(R.id.fragOne_btn_to2);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v)
{
String text = editText.getText().toString();
mListener.onFragmentOneInteraction(text);
}
});
return view;
}
#Override
public void onAttach(Context context) {
super.onAttach(context);
if (context instanceof OnFragmentOneInteractionListener) {
mListener = (OnFragmentOneInteractionListener) context;
} else {
throw new RuntimeException(context.toString()
+ " must implement OnFragmentOneInteractionListener");
}
}
#Override
public void onDetach()
{
super.onDetach();
mListener = null;
}
public interface OnFragmentOneInteractionListener
{
void onFragmentOneInteraction(String string);
}
}
And fragments two:
public class FragmentTwo extends Fragment{
private OnFragmentTwoInteractionListener mListener;
public EditText editText;
public FragmentTwo()
{
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
View view = inflater.inflate(R.layout.fragment_two, container, false);
editText = (EditText) view.findViewById(R.id.fragTwo_txb);
return view;
}
public void onUpdateEditText(String string)
{
this.editText.setText(string);
}
#Override
public void onAttach(Context context) {
super.onAttach(context);
if (context instanceof OnFragmentTwoInteractionListener) {
mListener = (OnFragmentTwoInteractionListener) context;
} else {
throw new RuntimeException(context.toString()
+ " must implement OnFragmentTwoInteractionListener");
}
}
#Override
public void onDetach()
{
super.onDetach();
mListener = null;
}
public interface OnFragmentTwoInteractionListener
{
void onFragmentTwoInteraction(Uri uri);
}
}
And this is my main activity:
public class MainActivity extends AppCompatActivity
implements FragmentOne.OnFragmentOneInteractionListener,
FragmentTwo.OnFragmentTwoInteractionListener
{
private SectionsPagerAdapter mSectionsPagerAdapter;
private ViewPager mViewPager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
mViewPager = (ViewPager) findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
mViewPager.addOnPageChangeListener(
new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.addOnTabSelectedListener(
new TabLayout.ViewPagerOnTabSelectedListener(mViewPager));
}
#Override
public void onFragmentOneInteraction(String string)
{
FragmentTwo fr2 = (FragmentTwo) getSupportFragmentManager().findFragmentById(R.id.fr2);
fr2.onUpdateEditText(string);
}
#Override
public void onFragmentTwoInteraction(Uri uri)
{
}
public class SectionsPagerAdapter extends FragmentPagerAdapter
{
public SectionsPagerAdapter(FragmentManager fm)
{
super(fm);
}
#Override
public Fragment getItem(int position)
{
switch (position)
{
case 0:
FragmentOne fragmentOne = new FragmentOne();
return fragmentOne;
case 1:
FragmentTwo fragmentTwo = new FragmentTwo();
return fragmentTwo;
default:
return null;
}
}
#Override
public int getCount()
{
// Show 2 total pages.
return 2;
}
}
}
I just tried your code and this is the update i did to make it work. Please mark it correct if its what you are looking for
private SectionsPagerAdapter mSectionsPagerAdapter;
private ViewPager mViewPager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
mViewPager = (ViewPager) findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
mViewPager.addOnPageChangeListener(
new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.addOnTabSelectedListener(
new TabLayout.ViewPagerOnTabSelectedListener(mViewPager));
}
#Override
public void onFragmentOneInteraction(String string)
{
fragmentTwo.onUpdateEditText(string);
/*FragmentTwo fr2 = (FragmentTwo) getSupportFragmentManager().findFragmentById(R.id.fr2);
fr2.onUpdateEditText(string);*/
}
#Override
public void onFragmentTwoInteraction(Uri uri)
{
}
FragmentTwo fragmentTwo = new FragmentTwo();
public class SectionsPagerAdapter extends FragmentPagerAdapter
{
public SectionsPagerAdapter(FragmentManager fm)
{
super(fm);
}
#Override
public Fragment getItem(int position)
{
switch (position)
{
case 0:
FragmentOne fragmentOne = new FragmentOne();
return fragmentOne;
case 1:
return fragmentTwo;
default:
return null;
}
}
#Override
public int getCount()
{
// Show 2 total pages.
return 2;
}
}
I suggest to use getActivity() instead
if (getActivity() instanceof OnFragmentOneInteractionListener) {
mListener = (OnFragmentOneInteractionListener) getActivity();
} else {
throw new RuntimeException(context.toString()
+ " must implement OnFragmentOneInteractionListener");
}

Need a little help on how to approach saving state in my single activity application. I looked at a few resources but couldn't quite find one that fits the build. Essentially I have single activity with a Fragment container view that I'm using to swap out fragments as needed. My issue is that as my activity is destroyed when a lifecycle event occurs, the fragment with my view pager is restored but the individual fragments on the tabs are not loaded. I cannot figure out how to save the state properly. Below is my code:
Activity:
public class StartActivity extends AppCompatActivity {
FirebaseAuth mAuth;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_start);
mAuth = FirebaseAuth.getInstance();
if (savedInstanceState == null) {
LoginFragment fragment = new LoginFragment();
getSupportFragmentManager()
.beginTransaction()
.add(R.id.frameLayout, fragment)
.commit();
}
}
#Override
public void onStart() {
super.onStart();
FirebaseUser currentUser = mAuth.getCurrentUser();
if(currentUser != null){
MainActivity mainActivityFrag = new MainActivity();
getSupportFragmentManager()
.beginTransaction()
.add(R.id.frameLayout, mainActivityFrag)
.commit();
}
}
#Override
public void onSaveInstanceState(#NonNull Bundle outState, #NonNull PersistableBundle outPersistentState) {
super.onSaveInstanceState(outState, outPersistentState);
}
#Override
protected void onRestoreInstanceState(#NonNull Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
}
}
Fragment With View Pager:
public class MainActivity extends Fragment {
private FirebaseAuth mAuth;
private SectionsPagerAdapter sectionsPagerAdapter;
private ViewPager viewPager;
private TabLayout tabs;
private Toolbar toolbar;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mAuth = mAuth = FirebaseAuth.getInstance();
}
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.activity_main, container, false);
sectionsPagerAdapter = new SectionsPagerAdapter(getContext(),((AppCompatActivity)getActivity()).getSupportFragmentManager());
viewPager = view.findViewById(R.id.view_pager);
viewPager.setAdapter(sectionsPagerAdapter);
tabs = view.findViewById(R.id.tabs);
tabs.setupWithViewPager(viewPager);
tabs.showContextMenu();
toolbar = view.findViewById(R.id.topAppBar);
((AppCompatActivity)getActivity()).setSupportActionBar(toolbar);
((AppCompatActivity)getActivity()).getSupportActionBar().setDisplayShowTitleEnabled(false);
setHasOptionsMenu(true);
tabs.getTabAt(0).setIcon(R.drawable.home_selector);
tabs.getTabAt(1).setIcon(R.drawable.destination);
tabs.getTabAt(2).setIcon(R.drawable.mail_outline_blk);
tabs.getTabAt(3).setIcon(R.drawable.notification_bell);
return view;
}
#Override
public void onCreateOptionsMenu(#NonNull Menu menu, #NonNull MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
menu.clear();
inflater.inflate(R.menu.main_menu, menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
super.onOptionsItemSelected(item);
switch (item.getItemId()){
case R.id.logout:
mAuth.signOut();
//navigate to home fragment
LoginFragment fragment = new LoginFragment();
((AppCompatActivity)getActivity()).getSupportFragmentManager()
.beginTransaction()
.replace(R.id.frameLayout, fragment)
.commit();
return true;
default:
return false;
}
}
#Override
public void onResume() {
super.onResume();
}
#Override
public void onSaveInstanceState(#NonNull Bundle outState) {
super.onSaveInstanceState(outState);
}
}
Adapter Code:
public class SectionsPagerAdapter extends FragmentPagerAdapter {
#StringRes
private static final int[] TAB_TITLES = new int[]{R.string.tab_text_1, R.string.tab_text_2, R.string.tab_text_3, R.string.tab_text_4};
private final Context mContext;
public SectionsPagerAdapter(Context context, FragmentManager fm) {
super(fm, BEHAVIOR_RESUME_ONLY_CURRENT_FRAGMENT);
mContext = context;
}
#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 0:
PostFragment postFragment = new PostFragment();
return postFragment;
case 1:
TestFragment userFeedFragmentt = new TestFragment();
return userFeedFragmentt;
default:
TestFragment userFeedFragmenttt = new TestFragment();
return userFeedFragmenttt;
}
}
#Nullable
#Override
public CharSequence getPageTitle(int position) {
return mContext.getResources().getString(TAB_TITLES[position]);
}
#Override
public int getCount() {
// Show 2 total pages.
return 4;
}
}
I am trying to pass information from my alert dialog to my second fragment (I am using tabbed activity layout).
I want to pass information from alert dialog to fragment when I click on my ImageView, but my app keep crashing until I implement my interface inside MainActivity.java. My main mission here is to open alert dialog which contains several buttons. When I click first button I want to print "Test br 3" but it does not work inside my Fragment, it only works inside my MainActivity.java where method prints "Test br 2".
My Main Activity
public class MainActivity extends AppCompatActivity implements ExercisesAlertDialog.DataTransfer {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
SectionsPagerAdapter sectionsPagerAdapter = new SectionsPagerAdapter(this, getSupportFragmentManager());
ViewPager viewPager = findViewById(R.id.view_pager);
viewPager.setAdapter(sectionsPagerAdapter);
TabLayout tabs = findViewById(R.id.tabs);
tabs.setupWithViewPager(viewPager);
}
#Override
public void ApplyData() {
System.out.println("Test br 2");
}
My Fragment
public class Frag2 extends Fragment implements ExercisesAlertDialog.DataTransfer {
ImageView plusbtn;
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.frag2, container, false);
plusbtn = (ImageView) v.findViewById(R.id.plusbtn);
plusbtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
ExercisesDialog();
}
});
return v;
}
public void ExercisesDialog()
{
ExercisesAlertDialog exercisesAlertDialog = new ExercisesAlertDialog();
exercisesAlertDialog.show(getFragmentManager(), "Exercises Dialog");
}
#Override
public void ApplyData() {
System.out.println("Test br 3");
}
My Alert Dialog
public class ExercisesAlertDialog extends AppCompatDialogFragment {
ImageButton one, two;
private DataTransfer listener;
public int first;
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
final AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
View v = inflater.inflate(R.layout.workout_custom_menu, null);
builder.setView(v);
builder.setTitle("Choose your Workout");
builder.setPositiveButton("Cancel", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dismiss();
}
});
one = (ImageButton) v.findViewById(R.id.first);
two = (ImageButton) v.findViewById(R.id.second);
one.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
first = 1;
if(first ==1)
{
listener.ApplyData();
}
}
});
return builder.create();
}
public interface DataTransfer
{
void ApplyData();
}
#Override
public void onAttach(Context context) {
super.onAttach(context);
try {
listener = (DataTransfer) context;
}
catch (ClassCastException e)
{
throw new ClassCastException(toString() + "Must implement DataTransfer");
}
}
}
I changed getChildFragmentManager() instead of getFragmentManager() in the show() call. Second thing is onAttach() to listener = (DataTransfer) getParentFragment(); instead of context.
I created my test project where i code to communicate between two fragments but actully I want to access activity from fragment.
Here is code to connect fragment to fragment, its working absolutely right without any error but now i want to change this code to connect activity from fragment instead of fragment to fragment communication.
So Please change this code to access activities from fragment. I stuck on this issue for than a week.So Guys please resolve this.
here is my mainaactivity:
public class MainActivity extends AppCompatActivity implements FragmentA.FragmentAListener, FragmentB.FragmentBListener {
private FragmentA fragmentA;
private FragmentB fragmentB;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
fragmentA = new FragmentA();
fragmentB = new FragmentB();
getSupportFragmentManager().beginTransaction()
.replace(R.id.container_a, fragmentA)
.replace(R.id.container_b, fragmentB)
.commit();
}
#Override
public void onInputASent(CharSequence input) {
fragmentB.updateEditText(input);
}
#Override
public void onInputBSent(CharSequence input) {
fragmentA.updateEditText(input);
}
Here is my FragmentA.java:
public class FragmentA extends Fragment {
private FragmentAListener listener;
private EditText editText;
private Button buttonOk;
public interface FragmentAListener {
void onInputASent(CharSequence input);
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_a, container, false);
editText = v.findViewById(R.id.edit_text);
buttonOk = v.findViewById(R.id.button_ok);
buttonOk.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
CharSequence input = editText.getText();
listener.onInputASent(input);
}
});
return v;
}
public void updateEditText(CharSequence newText) {
editText.setText(newText);
}
#Override
public void onAttach(Context context) {
super.onAttach(context);
if (context instanceof FragmentAListener) {
listener = (FragmentAListener) context;
} else {
throw new RuntimeException(context.toString()
+ " must implement FragmentAListener");
}
}
#Override
public void onDetach() {
super.onDetach();
listener = null;
}
}
Here is my FragmentB.java:
public class FragmentB extends Fragment {
private FragmentBListener listener;
private EditText editText;
private Button buttonOk;
public interface FragmentBListener {
void onInputBSent(CharSequence input);
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {

}
});
return v;
}
public void updateEditText(CharSequence newText) {
editText.setText(newText);
}
#Override
public void onAttach(Context context) {
super.onAttach(context);
if (context instanceof FragmentBListener) {

}
}
#Override

super.onDetach();
listener = null;
}

Here is my Fertilizers.java file which i want to access from FragmentA.:
public class Fertilizers extends AppCompatActivity {
RecyclerView mRecyclerView;
List<FertilizerData> myFertilizersList;
FertilizerData mFertilizersData;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_fertilizers);
mRecyclerView = (RecyclerView)findViewById(R.id.recyclerView);
GridLayoutManager gridLayoutManager;
gridLayoutManager = new GridLayoutManager(Fertilizers.this, 1);
mRecyclerView.setLayoutManager(gridLayoutManager);
myFertilizersList = new ArrayList<>();
mFertilizersData = new FertilizerData("Urea Fertilizer","Urea is a concent","Rs.1900",R.drawable.urea);
myFertilizersList.add(mFertilizersData);
myFertilizersList.add(mFertilizersData); }
}
please write here a block of code to call Fertilzers Activity from FragmentA, I,ll be very thankful to you.
Calling getActivity() in your fragment gives you the calling activity so if MainActivity started your fragment then you would do
(MainActivity(getActivity())).something_from_your_main_activity
Solution found by itself regarding this issue.
FragmentHome.java class should look like this:
public class FragmentHome extends Fragment {
private Button button;
public FragmentHome(){
}
public interface OnMessageReadListener
{
public void onMessageRead(String message);
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_home, container, false);
button = (Button)v.findViewById(R.id.bn);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(getActivity(), Fertilizers.class);
intent.putExtra("some"," some data");
startActivity(intent);
}
});
return v;
}
}
FertilizersActivity.java should look like this:
public class Fertilizers extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_fertilizers);
Bundle bundle = getIntent().getExtras();
if (bundle != null){
if(bundle.getStringArrayList("some") !=null){
Toast.makeText(getApplicationContext(),"data:" + bundle.getStringArrayList("some"),Toast.LENGTH_LONG).show();
}
}
}
}
I have a FloatingActionButton in my android navigation drawer with tablayout which displays the following message :
fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
homeFragment();
SnackBarMessage("Go To Inbox.");
}
});
using snackbar
public void SnackBarMessage(String message){
Snackbar.make(coordinatorLayout, message, Snackbar.LENGTH_LONG).setAction("Action", null).show();
}
let's say I have 3 tabs e.g (tab 0 ,tab 1 , tab 2)
how can I make the Floating action button take me to tab 2 once I click on it
This is the fragment containing the tabs

public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_home, container, false);
tabLayout = (TabLayout)view.findViewById(R.id.tabs);
mViewPager = (ViewPager)view.findViewById(R.id.container);
tabName=new ArrayList<String>();

for(int i=0;i<5;i++){
tabLayout.addTab(tabLayout.newTab().setIcon(tabIcons[i]));
tabName.add((strings[i]));
}
tabLayout.setTabMode(TabLayout.MODE_SCROLLABLE);
tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
mSectionsPagerAdapter = new SectionsPagerAdapter(getChildFragmentManager(),tabLayout.getTabCount(),tabName);
mViewPager.setAdapter(mSectionsPagerAdapter);
mViewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {

To be able to do this from another Fragment you will need to send a something in a Bundle, such as the position of the page, then do something like this:
HomeFragment fragment = new HomeFragment();
Bundle bundle = new Bundle();
bundle.putInt(YOUR_PAGE, youPage);
fragment.setArguments(bundle);
getSupportFragmentManager().beginTransaction().replace(R.id.container, fragment).addToBackStack("Name").commit();
Then in your HomeFragment:
Bundle bundle = this.getArguments();
if (bundle != null) { viewPager.setCurrentItem(bundle.getInt(YOUR_PAGE) }
Hello in my project I am to play a song when I click on a button and this button is is a fragment layout but I don't now if I need to put the code in the fragment or in the MainActivity. So here I put it in the fragment and the "protected" of the protected void is underline in red same for the "(this, resId)". Can someone help thanks a lot.
here is my fragment.java
public class thekairi78 extends Fragment {
private AdView adView;
private MediaPlayer mPlayer = null;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
