Adding text to element arraylist

I'm creating a listview of an element for my school's project and when I run the app it shows me the element's details. I want it to show a specific text but I can't find how to do it.
here is my java code:
private ArrayList<Playlist>playlists=new ArrayList<Playlist>();
ArrayAdapter<Playlist> adapter;
lvPlaylists=(ListView)findViewById(R.id.lvPlaylists);
adapter =new ArrayAdapter<Playlist>(Playlists.this, android.R.layout.simple_list_item_1, playlists);
lvPlaylists.setAdapter(adapter);
my function to get the items from the firebase cloud firestore to my arraylist
CollectionReference PlaylistsRef = db.collection("Users").document(Mail).collection("Playlists");
PlaylistsRef.get().addOnCompleteListener(new OnCompleteListener<QuerySnapshot>() {
#Override
public void onComplete(#NonNull Task<QuerySnapshot> task) {
if (task.isSuccessful()){
for (QueryDocumentSnapshot documentSnapshot : task.getResult())
{
if(!task.getResult().getDocuments().isEmpty())
{
String PlaylistName= (String)documentSnapshot.get("Name");
PlaylistsRef.document(PlaylistName).get().addOnSuccessListener(new OnSuccessListener<DocumentSnapshot>() {
#Override
public void onSuccess(DocumentSnapshot documentSnapshot) {
if (documentSnapshot != null){
Playlist playlist = new Playlist((String)documentSnapshot.get("Name"), (String)documentSnapshot.get("Genre"));
playlists.add(playlist);
lvPlaylists.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Intent intent=new Intent(Playlists.this,PlaylistView.class);
intent.putExtra("Name", adapter.getItem(position).getName());
intent.putExtra("Genre", adapter.getItem(position).getGenre());
intent.putExtra("PN", PN);
startActivity(intent);
}
});
adapter.notifyDataSetChanged();
}
}
});
}
}
}
}
});`
Playlist:
public class Playlist implements Serializable {
private String name;
private String genre;
private ArrayList<Song> songs;
public Playlist(String name, String genre, ArrayList<Song> songs)
{
this.name=name;
this.genre=genre;
this.songs=songs;
}
public Playlist(String name, String genre)
{
this.name=name;
this.genre=genre;
this.songs=null;
}
public Playlist()
{
this.name=null;
this.genre=null;
this.songs=null;
}
public void setName(String name)
{
this.name=name;
}
public String getName()
{
return this.name;
}
public void setGenre(String genre)
{
this.genre=genre;
}
public String getGenre()
{
return this.genre;
}
public ArrayList<Song> getSongs ()
{
return this.songs;
}
public void addSong (Song song)
{
songs.add(song);
}
public String ToString()
{
return this.name+" "+this.genre;
}
public void removeSong(Song song)
{
for(int i=0;i<this.songs.size();i++)
{
if(this.songs.get(i).getName()==song.getName())
{
this.songs.remove(i);
}
}
}
right now it shows me this when I run the app:
shows me the item's details and I want text

Passing data from Activity to Activity using Otto is not working

It's the first time that I'm using this library, but I was following this video tutorial to send data through Fragments, but in my case, it's just Activities.. So this how I did
Activity that I'm sending data :
public void onClick(View view) {
String passing_data = new Gson().toJson(user);
BusStation.getBus().post(new MessageData(passing_data));
Intent intent = new Intent(activity,UserAdsView.class);
activity.startActivity(intent);
}
BusStation Class :
public class BusStation {
private static Bus bus = new Bus();
public static Bus getBus() {
return bus;
}
}
MessageData Class :
public class MessageData {
private String msgData;
public MessageData(String msgData) {
this.msgData = msgData;
}
public String getMsgData() {
return msgData;
}
}
And finally at the UserAdsView Activity :
#Override
protected void onResume() {
super.onResume();
BusStation.getBus().register(this);
}
#Override
protected void onPause() {
super.onPause();
BusStation.getBus().unregister(this);
}
#Subscribe
public void recievedData(MessageData messageData){
target = messageData.getMsgData();
Toast.makeText(getApplicationContext(), target, Toast.LENGTH_SHORT).show();
}
As was mentioned on video, this method recievedData should be fired!

When you send notification in first activity at that time, UserAdsView Activity is not registered hence there are no listeners for events.
At this line
BusStation.getBus().post(new MessageData(passing_data));
you are sending notification but there is nothing registered to receive this notification. i.e. UserAdsView Activity has not started yet.
If you need to pass data to activity at launch time, simply send it via
Intent.

add in file Gradle
dependencies {
compile 'com.squareup:otto:1.3.8'
}
Create class OttoBus
public class OttoBus {
private static Bus sBus;
public static Bus getBus() {
if (sBus == null)
sBus = new Bus();
return sBus;
}
}
Create Events Class when pass data in android
public class Events {
public static class FragmentActivityMessage {
private String message;
public FragmentActivityMessage(String message) {
this.message = message;
}
public String getMessage() {
return message;
}
}
public static class ActivityFragmentMessage {
private String message;
public ActivityFragmentMessage(String message) {
this.message = message;
}
public String getMessage() {
return message;
}
}
}
function pass data
public void sendMessageToFragment(View view) {
EditText etMessage = findViewById(R.id.activityData);
OttoBus.getBus().post(String.valueOf(etMessage.getText()));
}
function event getdata
#Subscribe
public void getMessage(Events.ActivityFragmentMessage message) {
TextView messageView = findViewById(R.id.message);
messageView.setText(message.getMessage());
}

You need to make your MessageData object parcelable.
Then in your onClick() :
public void onClick(View view) {
String passing_data = new Gson().toJson(user);
Bundle extras = new Bundle();
extras.putParcelable("key",new MessageData(passing_data));
Intent intent = new Intent(activity,UserAdsView.class);
intent.putExtras(extras)
activity.startActivity(intent);
}
Then in onCreate() of your UserAdsView Activity :
MessageData data = (MessageData)getIntent().getExtras().getParcelable("key");

Unable to instantiate Sinch client- NullPointerException Error

I am using a Sinch tutorial(https://github.com/sinch/android-app-app-calling-headers) as a framework for an app I am trying to develop. The following is the login class from the tutorial which I have updated and been successful in initializing the sinch client.
public class LoginActivity extends BaseActivity implements SinchService.StartFailedListener {
private Button mLoginButton;
private EditText mLoginName;
private static final int REQUEST_PERMISSION = 10;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.login);
mLoginName = (EditText) findViewById(R.id.loginName);
mLoginButton = (Button) findViewById(R.id.loginButton);
mLoginButton.setEnabled(false);
requestAppPermissions(new String[]{Manifest.permission.RECORD_AUDIO, Manifest.permission.ACCESS_FINE_LOCATION}, R.string.msg, REQUEST_PERMISSION);
mLoginButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
loginClicked();
}
});
}
#Override
public void onPermissionGranted(int requestCode) {
}
#Override
protected void onServiceConnected() {
mLoginButton.setEnabled(true);
getSinchServiceInterface().setStartListener(this);
}
#Override
protected void onPause() {
super.onPause();
}
#Override
public void onStartFailed(SinchError error) {
Toast.makeText(this, error.toString(), Toast.LENGTH_LONG).show();
}
#Override
public void onStarted() {
openPlaceCallActivity();
}
private void loginClicked() {
String userName = mLoginName.getText().toString();
if (userName.isEmpty()) {
Toast.makeText(this, "Please enter a name", Toast.LENGTH_LONG).show();
return;
}
if (!getSinchServiceInterface().isStarted()) {
getSinchServiceInterface().startClient(userName);
} else {
openPlaceCallActivity();
}
}
private void openPlaceCallActivity() {

}
The instantiation of the client occurs in the SinchService Class which is as follows:

mSinchClient.setSupportCalling(true);
mSinchClient.startListeningOnActiveConnection();
mSinchClient.addSinchClientListener(new MySinchClientListener());
mSinchClient.getCallClient().addCallClientListener(new SinchCallClientListener());

}
For my purposes, I need to derive the username for the client from my shared preferences folder. I made a dummy app that uses the same framework above with the addition of shared preferences but I always get a NullPointerException error. The following is my login class from my dummy app.
public class LoginActivity extends BaseActivity implements SinchService.StartFailedListener {
private EditText mLoginName, recipientName, coordinateA, coordinateB;
private Button loginButton;
private static final int REQUEST_PERMISSION = 10;
public static final String DEFAULT = "N/A";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
userName = (EditText) findViewById(R.id.userInput);
recipientName = (EditText) findViewById(R.id.recipientInput);
loginButton = (Button) findViewById(R.id.loginButton);
requestAppPermissions(new String[]{Manifest.permission.RECORD_AUDIO, Manifest.permission.ACCESS_FINE_LOCATION}, R.string.msg, REQUEST_PERMISSION);
SharedPreferences sharedPreferences = getSharedPreferences("MyData", MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putString("user_name", mLoginName.getText().toString());
editor.putString("recipient_name", recipientName.getText().toString());
editor.commit();
loginButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
loginClicked();
}
});
}
#Override
public void onPermissionGranted(int requestCode) {
}
#Override
protected void onServiceConnected() {
getSinchServiceInterface().setStartListener(this);
}
#Override
protected void onPause() {
super.onPause();
}
#Override
public void onStartFailed(SinchError error) {
Toast.makeText(this, error.toString(), Toast.LENGTH_LONG).show();
}
#Override
public void onStarted() {
openPlaceCallActivity();
}
private void loginClicked() {
SharedPreferences sharedPreferences = getSharedPreferences("MyData", MODE_PRIVATE);
String userName = sharedPreferences.getString("user_name", DEFAULT);
if (userName.isEmpty()) {
Toast.makeText(this, "Please enter a name",
Toast.LENGTH_LONG).show();
return;
}
if (!getSinchServiceInterface().isStarted()) {
getSinchServiceInterface().startClient(userName);
} else {
openPlaceCallActivity();
}
}
private void openPlaceCallActivity() {
Intent mainActivity = new Intent(LoginActivity.this, PlaceCallActivity.class);
startActivity(mainActivity);
}
}
When comparing my login class with the tutorial's login class-- the only difference is where the variable "userName" is derived. We both have a value attached to the username; however, only one client is able to establish while the other throws a NullPointerException Error. Anyone know why?

Try this :
on your BaseActivity.java
instead of
protected void onServiceConnected() {
// for subclasses
}
put
protected void onServiceConnected(IBinder iBinder) {
mSinchServiceInterface = (SinchService.SinchServiceInterface) iBinder;
}
and in your LoginActivity.java
Override the function onServiceConnected(IBinder iBinder)
#Override
protected void onServiceConnected(IBinder iBinder) {
super.onServiceConnected(iBinder);
getSinchServiceInterface().setStartListener(this);
}

Working with Sinch Instant Messaging System

I am using Sinch and Parse for my instant messaging system integrated in our application, and I have two concerns.
1) For some reason, I am receiving the following error when the messaging activity is displayed: The message client did not start". Furthermore, the message does not seem to go through in Sinch and not reflected visually in the application.
Below is the activity code (when the user clicks on the "quick chat" button, it takes them to the messaging activity page.

I have verified that the APP_KEY, the APP_SECRET and ENVIRONMENT matches what was recorded on Sinch.
I have tried this both on the emulator, and on a physical device.
Thanks in advance

2) Limit: I would like to set a limit, where a only 25 messages would be available between a particular party.
Thanks in advance, and if you need any clarification, let me know.
Update 3
When user clicks on this button, he is taking to the MessagingActivity with the person he has been matched to based upon the below criteria
final Button ibutton = (Button) this.findViewById(R.id.btnQuickChat);

#Override
public void onClick(View v) {
openConversation();
}
private void openConversation() {

if (e == null) {

I wrote the tutorial you're following, and actually just updated it yesterday to fix your first problem. Check out http://tutorial.sinch.com/android-messaging-tutorial/#show-spinner to see the updates. Instead of showing a toast message when the service is not started, the new version will show a progress dialog (loading spinner) until the service has either started or failed to start.
Could you clarify your second question?

Just declare your service in manifest. I had the same problem and it solved it.
