}
when I tried to run the app this crashed and in the log file he says error in this line:
DisplayItem [] displayItem = (DisplayItem[])
intent2.getExtras().getSerializable("DisplayItem");
Thank you very much for helping!


Your code is not too clear but try use this format:
//When you want to pass an array as intent:
private ArrayList<String> arrayList = new ArrayList<String>();
Intent intent = new Intent();
intent.putStringArrayListExtra("data", arrayList);
startActivity(intent);
// To receive intent in the second activity
private ArrayList<String> newArrayList = new ArrayList<String>();
newArrayList = getIntent.getStringArrayListExtra("data");


Check if your classes Device and Customer implements serializable

Somebody please help me I am Newbie to this.

This is another method of sending data from Adapter to Activity.
Follow these steps carefully:
Create an interface with a method
public interface InterfaceTax {
public void getTaxMoney(int amount);
}
the parameters of the method should contain the data you want to send back to the activity.
Create a variable for that interface in the Adapter and add the interface to the constructor of the Adapter.
private InterfaceTax interfaceT;
public ChannelAdapter(/* other parameters */, InterfaceTax interface) {
interfaceT = interface;
}
Then in onBindViewHolder (or wherever your data is) call the method of the interface and send the data
#Override
public void onBindViewHolder(#NonNull MyViewHolder holder, int i) {
money = String.valueOf(channel_tMoney.get(i));
interface.getTaxMoney(money);
}
Then in your activity implement the interface and override the method to receive data
public class UserDetailsActivity extends AppCompatActivity implements InterfaceTax {}
#Override
public void getTaxMonney(int data) {
// receive data here
}
In your AddChannel method, replace this line
ChannelAdapter cAdapter = new ChannelAdapter(UserDetailsActivity.this,this,channel_id,channel_name,channel_ntMoney,channel_tMoney);
with this
ChannelAdapter cAdapter = new ChannelAdapter(UserDetailsActivity.this,this,channel_id,channel_name,channel_ntMoney,channel_tMoney, this);
This will automatically send the data from the adapter to the activity and you can receive it in the method overridden in the activity.

Firebase chat app not displaying messages like whatsapp does

I am trying to come up with a chat app using Firebase Recycler adapter. The problem is that the sender's and receiver's chats are not displayed as expected. All the chats are displayed on the right. Despite the text being "Morning", the text is displayed as "Hello".

I need some assistance

Trying to write something in one activity and reading it in the next activity

Im currently creating a barber application and at the moment, on my landing page i have a button that when clicked it will bring up a popup window for the user to enter their name and contact number
Now what i want to do is when the user clicks view appointments it shows what appointments there are on the page name ContactUs.java
So here is my Landing.java page
package ie.app.barbershop;
import android.content.Intent;
import android.os.Bundle;
import android.os.Parcel;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;

buttonProducts.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
startActivity(new Intent(Landing.this, Products.class));
}
});
button4.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
startActivity(new Intent(Landing.this, ContactUs.class));
}
});
}
public void readRecords() {
LinearLayout linearLayoutRecords = findViewById(R.id.linearLayoutRecords);
linearLayoutRecords.removeAllViews();
List<ObjectAppointment> appointments = new TableControllerAppointments(this).read();
if (appointments.size() > 0) {
for (ObjectAppointment obj : appointments) {
String fullName = obj.fullName;
int contactNumber = obj.contactNumber;
String textViewContents = fullName + " - " + contactNumber;
TextView textViewAppointmentItem= new TextView(this);
textViewAppointmentItem.setPadding(0, 10, 0, 10);
textViewAppointmentItem.setText(textViewContents);
textViewAppointmentItem.setTag(Integer.toString(contactNumber));
linearLayoutRecords.addView(textViewAppointmentItem);
}
}
else {
TextView locationItem = new TextView(this);
locationItem.setPadding(8, 8, 8, 8);
locationItem.setText("No records yet.");
linearLayoutRecords.addView(locationItem);
}
}
public void countRecords(){
int recordCount = new TableControllerAppointments(this).count();
TextView textViewRecordCount = findViewById(R.id.textViewRecordCount);
textViewRecordCount.setText(recordCount + " records found.");
}
}
This is my ContactUs.Java page(This should be called ViewAppointments.java but it was originally meant to be a contact us page)

public class ContactUs extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.contact_us);
}
}
This is my onclicklistenerCreateAppointment.java page
package ie.app.barbershop;
import android.view.View;
import android.content.Context;
import android.view.LayoutInflater;
import android.widget.EditText;
import android.app.AlertDialog;
import android.content.DialogInterface;

#Override
public void onClick(View view){
final Context context = view.getRootView().getContext();

Toast.makeText(context, "Appointment Information was saved.", Toast.LENGTH_SHORT).show();
}else{

}
And this is my TableControllerAppointments.java
package ie.app.barbershop;

SQLiteDatabase db = this.getWritableDatabase();
boolean createSuccessful = db.insert("appointments", null, values) > 0;
db.close();
return createSuccessful;
}
public List<ObjectAppointment> read() {
List<ObjectAppointment> recordsList = new ArrayList<>();

recordsList.add(objectAppointment);
} while (cursor.moveToNext());
}
cursor.close();
db.close();
return recordsList;
}
public int count() {
SQLiteDatabase db = this.getWritableDatabase();
String sql = "SELECT * FROM appointments";
int recordCount = db.rawQuery(sql, null).getCount();
db.close();
return recordCount;
}
}
Any other info you need im more than happy to provide if i have forgotten something.

I need to pass the List array from one activity to another and populate the listView I have from the shuffeld array, but something is crashing my app when i click on the button that takes me to the next activity. I dont know if this is correctly done and what is the problem causing it to entirely crash...

you can try this
in first acticity
Intent intent = new Intent(context, NewActivity.class);
intent.putExtra("mylist", yourlist_array);
context.startActivity(intent);
in second activity
Intent intent = getIntent();
List stringArray = intent.getStringArrayExtra("mylist");

Do this:
ArrayList<String> filled_spots = new ArrayList<>(Arrays.asList("nome1", "nome2"));
Collections.shuffle(filled_spots); //Shuffle List
Collections.sort(filled_spots); //Sort List
Intent teams_Screen = new Intent (MainActivity.this, DisplayTeamsActivity.class);
teams_Screen.putStringArrayListExtra("mylist", filled_spots);
At DisplayTeamsActivity you'll need do this:
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ArrayList<String> stringList = getIntent().getStringArrayListExtra("mylist");
}

startActivity(intent);
}
});
}
}
I try to pass data from this ListView to another EditText in an other
activity but the result is always null, I want to pass all the text
string from the ListView to the EditText.

Do this way,
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position, long id)
{
Intent intent = new Intent(getApplicationContext(), SingleUser.class);
intent.putExtra("username", YourModels.get(position).getUsername());//here first get position and than pass data you want to pass
intent.putExtra("fk_Code", "" + YourModels.get(position).getFk_Code());//take data from your model
startActivity(intent);
}
});

It was too simple i found a simple solution i created a bunch of
string arrays that contains each of the data fetched from the DB and
stored in them, so now i can choose from those String arrays by
position, but thanks anyway
