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
public class MainActivity extends AppCompatActivity {

private ImageView btn_Play;

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.

private ArrayList<SoundInfo> audioList = new ArrayList<>();

public MassiveAudioList(Context context) {

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" },

I have 4 different Charts in 4 fragment in one Activity but it dose not work?

I want Show 4 Charts in one Activity into 4 Fragments. I use achartengine for my Line Chart ,Bar Chart ,Pie Chart ,Doughnut Char ; I have chart class and Fragment class for each charts and one ChartItemEntity class, my main class is ChartsFragmentActivity,
I do not know where is my fault, can anyone help?
My ChartsFragmentActivity Class:
public class ChartsFragmentActivity extends Activity {
/** Called when the activity is first created. */

}
public BarFragment BarChart_Show(View view) {
BarFragment _containerBarChart = (BarFragment) getFragmentManager().findFragmentById(R.id.bfBarFragment);
return (_containerBarChart);
}
public PieFragment PieChart_Show(View view) {

I want to use Async task to put all Ui in postexecute and loops in doinbackground?
In loop i have my table row which consumens 5secs to 8sec to load so can we somehow add the loop in do in background? Any help would be appreciated. Please provide code sample for better understanding

First define what is your time consuming task. If you want creation of your Table to be in asyncTask here is a hint how to do it. First you need to create entire Table off screen and then add it to your Layout
private TableLayout table;
private void init(){
new CustomTask().execute();
}
private class CustomTask extends AsyncTask<String, Void, Boolean>{
private ProgressDialog dialog;
#Override
protected void onPreExecute() {
super.onPreExecute();
dialog=ProgressDialog.show(getContext(), "", "Loading...");
}
#Override
protected Boolean doInBackground(String... params) {
// Here is the part where you create your table and do extensive work
// For example
for(int i =0; i< sectionNames.size();i++){
TableRow tr = new TableRow(context);
View line = new View(context);
line.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, 1));
line.setBackgroundColor(textNormalColor);
line.setPadding(0, 10, 0, 10);
layoutInflater.inflate(R.layout.sectiontablerow, tr);
table.addView(tr, new TableLayout.LayoutParams(TableLayout.LayoutParams.WRAP_CONTENT, TableLayout.LayoutParams.WRAP_CONTENT));
table.addView(line);
setIds(tr);
setTagstoViews(i);
addViewstoList();
setListeners();
checkIfSectionIsOn(i);
tList.get(i).setText("sai ram");
}
return null;
}
#Override
protected void onPostExecute(Boolean result) {
super.onPostExecute(result);
//And now add your tableLayout in your Layout
layout.addView(tableLayout);
// Adjust layout params per need
dialog.dismiss();
}
}
Adjust all of this according to your needs.
Hope this helps and enjoy your work.
