How to pass mediaplayer data from service to fragment in android

I'm making an app that play mp3 file from phone storage using service. I have an activity that has a small view to interact with the songs and a fragment that contains a full media function to interact with the songs will be added in if I tap on the small view told. The problem is I cannot get data from service to pass in the fragment to display data or interact between fragment and service.
Here's my main activity 1st photo
Here's my fragment after touch the field on 1st photo fragment
My code in MainActivity
public class MainActivity extends AppCompatActivity {
private List<AudioModel> mainList;

You can use a broadcast in your service and set broadcast listener in your fragment.

Hello, please tell me how to send ArrayList to another activity

I tried all the possible options that I just found.
I can’t send ArrayList to another activity via the Parcelable interface.
To implement a media player
String format information it sends.
I would be very grateful, maybe there are some other options. This is the first time I'm asking a question here
Here is my activity that I use to send, the code is still very raw

Here is the second activity that an ArrayList gets.
Bundle bundle = getIntent().getExtras();
ArrayList<SoundInfo> audioList = bundle.getParcelableArrayList("MEDIA_MASSIVE");
adapter.setItems(MainMediaPlayList.this, audioList);
adapter.notifyDataSetChanged();
// загрузка адаптера
RecyclerView list = findViewById(R.id.my_recycler_view);
list.setAdapter(adapter);
list.setLayoutManager(new LinearLayoutManager(MainMediaPlayList.this));
When you open a new activity, the application crashes
does not display any errors in the log, the problem is as I understand that intent can not find
audioList as it seems to me
If I remove the method everything loads
public void onMainMediaPlayList(View view) {
final Intent intent2 = new Intent(getApplicationContext(), MainMediaPlayList.class);
Bundle bundle = new Bundle();
bundle.putParcelableArrayList("MEDIA_MASSIVE", audioList);
intent2.putExtras(bundle);
startActivity(intent2);
Here I took off the launch log, it may somehow help

I don't think so, You can send an ArrayList like this.
I recommend you sending Class instead of sending an Arraylist.
So, just create a class like AudiolistHolder and put your ArrayList inside this class and don't forget to implement Parcelable interface for this class, too, and send this class between activities this should solve your problem. I always use this way.
EDIT:
You can use this to send your data
Intent intent2 = new Intent(this, MainMediaPlayList.class);
MassiveAudioList m = new MassiveAudioList(audioList);
intent2.putExtra("MEDIA_MASSIVE”, m);
startActivity(intent2);
and you can use this in your second activity to retrieve data
MassiveAudioList massiveAudio=getIntent().getParcelableExtra("MEDIA_MASSIVE");
ArrayList<SoundInfo> audioList = massiveAudio.getMassiveAudioList();

Have you tried like this with arraylist
I think it can be,
In MainActivity.java
ArrayList<String> audioList= new ArrayList<>();
audioList.add("ChipThrills");
Intent i = new Intent(MainActivity.this, Secondactivity.class);
i.putExtra("Musickey", audioList);
startActivity(i);
In SecondActivity.java
ArrayList<String> audioList = (ArrayList<String>) getIntent().getSerializableExtra("Musickey");

I am writing to you here because I did not understand how to add code to the comment
And how do I extract data by adding it to an array. If of course I did the right thing, I'm new to this field. Thanks.

I tried to use this code, from Mr Abhi instruction, I just edited a little bit for removing the toolbar, and some I solved.
This is my fragment.java
public class ToDoListFragment extends Fragment implements BatListener, OnItemClickListener, OnOutsideClickedListener {
private BatRecyclerView mRecyclerView;
private BatAdapter mAdapter;
private List<BatModel> mGoals;
private BatItemAnimator mAnimator;
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View root = inflater.inflate(R.layout.todo_list_fragment, null);
return root;
}
public void onViewCreated(View view, Bundle savedInstanceState) {
// you can add listener of elements here
/*Button mButton = (Button) view.findViewById(R.id.button);
mButton.setOnClickListener(this); */
((TextView) view.findViewById(R.id.tdl_date)).setTypeface(TypefaceUtil.getAvenirTypeface(getActivity()));
mRecyclerView = (BatRecyclerView) view.findViewById(R.id.tdl_bat_recyclerView);
mAnimator = new BatItemAnimator();
mRecyclerView.getView().setLayoutManager(new LinearLayoutManager(getActivity()));
mRecyclerView.getView().setAdapter(mAdapter = new BatAdapter(mGoals = new ArrayList<BatModel>() {{
}}, this, mAnimator).setOnItemClickListener(this).setOnOutsideClickListener(this));
ItemTouchHelper itemTouchHelper = new ItemTouchHelper(new BatCallback(this));
itemTouchHelper.attachToRecyclerView(mRecyclerView.getView());
mRecyclerView.getView().setItemAnimator(mAnimator);
mRecyclerView.setAddItemListener(this);
view.findViewById(R.id.root).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mRecyclerView.revertAnimation();
}
});
}
#Override
public void add(String string) {
mGoals.add(0, new Goal(string));
mAdapter.notify(AnimationType.ADD, 0);
}
#Override
public void delete(int position) {
mGoals.remove(position);
mAdapter.notify(AnimationType.REMOVE, position);
}
#Override
public void move(int from, int to) {
if (from >= 0 && to >= 0) {
mAnimator.setPosition(to);
BatModel model = mGoals.get(from);
mGoals.remove(model);
mGoals.add(to, model);
mAdapter.notify(AnimationType.MOVE, from, to);
if (from == 0 || to == 0) {
mRecyclerView.getView().scrollToPosition(Math.min(from, to));
}
}
}
#Override
public void onClick(BatModel item, int position) {

#Override

But it crushed when I started the app. the log showed that No view found for id 0x7f09004c (package:id/container) for fragment.
I hope you guys could help me as you teach me. Thanks for the second time.

To convert an Activity to a Fragment, you first have to extend Fragment. then you'll have to make some basic necessary changes in the code like:
1.onCreateView(LayoutInflater, ViewGroup, Bundle) instead of onCreate
2.findViewById() becomes getView().findViewById().
Your sample code:
public class ToDoList extends Fragment implements BatListener, OnItemClickListener, OnOutsideClickedListener {
private BatRecyclerView mRecyclerView;
private BatAdapter mAdapter;
private List<BatModel> mGoals;
private BatItemAnimator mAnimator;
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View root = inflater.inflate(R.layout.todo_list_fragment, null);
return root;
}
public void onViewCreated(View view, Bundle savedInstanceState) {
// you can add listener of elements here
/*Button mButton = (Button) view.findViewById(R.id.button);
mButton.setOnClickListener(this); */
// Navigator
FoldingTabBar tabBar = (FoldingTabBar) view.findViewById(R.id.folding_tab_bar);
tabBar.setOnFoldingItemClickListener(new FoldingTabBar.OnFoldingItemSelectedListener() {
#Override
public boolean onFoldingItemSelected(#NotNull MenuItem item) {
switch (item.getItemId()) {
case R.id.menu_profile:
Intent intent0 = new Intent(ToDoList.this, Home.class);
startActivity(intent0);
break;
case R.id.menu_todo:
break;
case R.id.menu_schedule:
Intent intent1 = new Intent(ToDoList.this, TimeTable.class);
startActivity(intent1);
break;
case R.id.menu_settings:
break;
}
return false;
}
});
((AppCompatActivity)getActivity()).setSupportActionBar(toolbar);
((TextView) view.findViewById(R.id.text_title)).setTypeface(TypefaceUtil.getAvenirTypeface(this));
mRecyclerView = (BatRecyclerView) view.findViewById(R.id.bat_recycler_view);
mAnimator = new BatItemAnimator();
mRecyclerView.getView().setLayoutManager(new LinearLayoutManager(this));
mRecyclerView.getView().setAdapter(mAdapter = new BatAdapter(mGoals = new ArrayList<BatModel>() {{
}}, this, mAnimator).setOnItemClickListener(this).setOnOutsideClickListener(this));
ItemTouchHelper itemTouchHelper = new ItemTouchHelper(new BatCallback(this));
itemTouchHelper.attachToRecyclerView(mRecyclerView.getView());
mRecyclerView.getView().setItemAnimator(mAnimator);
mRecyclerView.setAddItemListener(this);
view.findViewById(R.id.root).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mRecyclerView.revertAnimation();
}
});
}
#Override
public void add(String string) {
mGoals.add(0, new Goal(string));
mAdapter.notify(AnimationType.ADD, 0);
}
#Override
public void delete(int position) {
mGoals.remove(position);
mAdapter.notify(AnimationType.REMOVE, position);
}
#Override
public void move(int from, int to) {
if (from >= 0 && to >= 0) {
mAnimator.setPosition(to);
BatModel model = mGoals.get(from);
mGoals.remove(model);
mGoals.add(to, model);
mAdapter.notify(AnimationType.MOVE, from, to);
if (from == 0 || to == 0) {
mRecyclerView.getView().scrollToPosition(Math.min(from, to));
}
}
}
#Override
public void onClick(BatModel item, int position) {
Toast.makeText(this, item.getText(), Toast.LENGTH_SHORT).show();
}
#Override
public void onOutsideClicked() {
mRecyclerView.revertAnimation();
}
}
I haven't edited all code and further changes maybe required. Do the changes accordingly.

How to sort recyclerView, Bold item if unread and unbold if item opened?

I have 2 Activities in my application.
activityMain contain 3 Fragments
The third fragment is a conversations list. This is a recylerView where each Item leads to a specific chat.
activityConversation contains a Chat.
First, i would like to sort the conversations in the the recyclerView in order of "Last actives". The most recent active should be displayed on top of the list, the second last active on second postition etc...
Secondly, each Item of the recyclerView contains a Textview. For each item, I would like to display the last message posted in the related chat in this Texview.
Finally, i would like to display these Item textViews in Bold since the conversation has not been opened until the last chat update.
Has anyone an Idea to help me achieve that?
Here my Chat Activity:

Thank you in advance for your time.

maintain a flag in data level to know is it read or unread,based on that you can apply the styles.

There is two way to do this.
First you can ask to backend to write server side to query to handle last activity bases of timestamp .In this case you have to send your particular timestamp to server when you open particular conversation .
Other you can make local database ex-(sql database) and handle it in your own code by updating query when you reading or undreading conversation.

Button's click listener in listiview not working which extends Fragment

If I put button lister in BasicAdapter,it can call ,too.But I want the button'click listener in Fragment.Any suggestion will be appreciated.

this.Adapter = new BasicAdapter(getActivity(), List, Resource,
new String[] { "Provider", "ProdName", "NoType", "ContractNo",
"AcceptTime", "ContractStatus", "Premium", "Gain",
"ReceivedPremium", "Name" },
Fragment is implementing the listener and not the activity. So you should do
this.Adapter = new BasicAdapter(this, List, Resource,
new String[] { "Provider", "ProdName", "NoType", "ContractNo",
"AcceptTime", "ContractStatus", "Premium", "Gain",
"ReceivedPremium", "Name" },
