How can I save a list within a list using the room persistence library? (android & Java)

how are you, I hope everyone is fine
I have created an application to generate a sales invoice.
In SalesInvoiceActivity, when the user clicks on the FloatingActionButton, it goes to AddSaleInvoiceActivity.
addSaleInvoiceFab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
startActivity(new Intent(SalesInvoiceActivity.this, AddSaleInvoiceActivity.class));
}
});
In AddSaleInvoiceActivity there is an EditText and Date to store the name of the customer and invoice date in RecyclerView list in SalesInvoiceActivity.
customerName = addCustomerNameEt.getText().toString();
date = new Date();
When the user presses the Save Invoice button, the invoice number is saved with the ID, the invoice date, and the customer's name.
final SaleInvoiceEntry saleInvoiceEntry = new SaleInvoiceEntry(customerName, date);
appDatabase.salesInvoiceDao().insertSaleInvoice(saleInvoiceEntry);
#Entity(tableName = "saleInvoice")
public class SaleInvoiceEntry {
#PrimaryKey(autoGenerate = true)
private int id;
#ColumnInfo(name = "customerName")
private String customerName;
#ColumnInfo(name = "invoiceDate")
private Date invoiceDate;
#Ignore
public SaleInvoiceEntry(String customerName, Date invoiceDate) {
this.customerName = customerName;
this.invoiceDate = invoiceDate;
}
public SaleInvoiceEntry(int id) {
this.id = id;
}
public void setId(int id) {
this.id = id;
}
public int getId() {
return id;
}
public void setCustomerName(String customerName) {
this.customerName = customerName;
}
public String getCustomerName() {
return customerName;
}
public void setInvoiceDate(Date invoiceDate) {
this.invoiceDate = invoiceDate;
}
public Date getInvoiceDate() {
return invoiceDate;
}
}

#Query("SELECT * FROM saleInvoice ORDER BY id")

Now how do I store the AddProductToSalesInvoiceEntry list inside the SaleInvoiceEntry list when the user clicks the save invoice button ?

Please help me to do this.

Add different layout between item in RecyclerView-AndroidX

I want to add Different layout between item in my recyclerview, I have 3 item in first layout, and then I add second layout to item number 2, so It should have 4 item right now, (1-FirstLayout)-(2-SecondLayout)-(3FirstLayout)-(4FirstLayout), but I realize the position that I choose from my second layout replaced to the position first layout it becomes like this (1-FirstLayout)-(2-SecondLayout)-(3FirstLayout)
Iam not sure how to fix it

You have implemented this method wrong
#Override
public int getItemCount() {
int itemCount = 0;
if(mWithTopReviewer == true){
itemCount++;
}
itemCount = modelGameReviews.size();
return itemCount;
}
It should be something similar
#Override
public int getItemCount() {
int itemCount = modelGameReviews.size();
if(mWithTopReviewer == true){
itemCount++;
}
return itemCount;
}

new item is not getting added in recyclerview?

i am scanning devices from a bluetooth and getting their data from their advertisement,so one of the device gives the data of other devices which is not in ranged from the mobile device,so i specifically filter the data of that device which i wanted to show in recycler view in automatically updating the rssi values.
let's say,
a device A which gives the data of 3 devices B,C,D containing their rssi values continuously,so what i want to show the list of device B,C,D with their rssi values which is changing continuously.
What i have done until now is scan that device "A",and extract the data of B and shown in recyclerview,but when another device i.e C's data comes in the old device i.e B got vanished and so on.
what i want is continuously changing data of B,C,D.

How to show multiple data source data in single recycle view or adapter using LazyLoading?

The above image is a simple design that I want to develop.
I have four type of different data with different view type like the below image enter image description here. but that is not a problem. problem is the data will come from different API with lazy loading like when user scroll the list from recycle view it will grab the data from the server. My question is how to combine them in a single adapter because I need to use lazy loading .so I can't load whole data at a time so I need to call the different type of API like goal-list API, appraisal API, post API etc. When user scroll. anyone can give me an idea with example. How can I handle that? Also when user will scroll it will call another api likeCount and comment count also. Currently, In my, I am calling single API and show that in the single recycle view. Currently, I am using android architecture component LiveData
