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.

So I am relatively new to programming, and I have been working on this task app, where I want to save the data such as task name and more, given by the user. I am trying to accomplish this using Room. Now, initially, when I tried to do it, the app would crash since I was doing everything on the main thread probably. So, after a little research, I came to AsyncTask, but that is outdated. Now finally I have come across the Executer. I created a class for it, but I am a little unsure as to how I can implement it in my app. This is what I did :
Entity Class :
#Entity (tableName = "subtasks")
public class SubtaskDetails {
#PrimaryKey(autoGenerate = true)
private int id;
#ColumnInfo(name = "subtaskName")
private String subtasksName;
#ColumnInfo(name = "priority")
private boolean priHigh;
private boolean priMed;
private boolean priLow;
#ColumnInfo(name = "time")
private boolean timeMore;
private boolean timeMed;
private boolean timeLess;
public SubtaskDetails(String subtasksName, boolean priHigh, boolean priMed, boolean priLow, boolean timeMore, boolean timeMed, boolean timeLess){
this.subtasksName = subtasksName;
this.priHigh = priHigh;
this.priMed = priMed;
this.priLow = priLow;
this.timeMore = timeMore;
this.timeMed = timeMed;
this.timeLess = timeLess;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getSubtasksName() {
return subtasksName;
}
public void setSubtasksName(String subtasksName) {
this.subtasksName = subtasksName;
}
public boolean isPriHigh() {
return priHigh;
}
public void setPriHigh(boolean priHigh) {
this.priHigh = priHigh;
}
public boolean isPriMed() {
return priMed;
}
public void setPriMed(boolean priMed) {
this.priMed = priMed;
}
public boolean isPriLow() {
return priLow;
}
public void setPriLow(boolean priLow) {
this.priLow = priLow;
}
public boolean isTimeMore() {
return timeMore;
}
public void setTimeMore(boolean timeMore) {
this.timeMore = timeMore;
}
public boolean isTimeMed() {
return timeMed;
}
public void setTimeMed(boolean timeMed) {
this.timeMed = timeMed;
}
public boolean isTimeLess() {
return timeLess;
}
public void setTimeLess(boolean timeLess) {
this.timeLess = timeLess;
}
}
Dao Class:
#Dao
public interface UserDao {
#Query("Select * from subtasks")
List<SubtaskDetails> getSubtaskDetailsList();
#Insert
void insertSubtaskDetails(SubtaskDetails subtaskDetails);
#Update
void updateSubtaskDetails(SubtaskDetails subtaskDetails);
#Delete
void deleteSubtaskDetails(SubtaskDetails subtaskDetails);
}
App Database Class :
#Database(entities = SubtaskDetails.class, exportSchema = false, version = 1)
public abstract class AppDatabase extends RoomDatabase {
private static final String DB_NAME = "subtaskdetails_db";
private static AppDatabase instance;
public static synchronized AppDatabase getInstance(Context context){
if (instance == null){
instance = Room.databaseBuilder(context.getApplicationContext(), AppDatabase.class, DB_NAME).fallbackToDestructiveMigration().build();
}
return instance;
}
public abstract UserDao subtaskdetailsdao();
}
Executer Class :
public class AppExecutors {
// For Singleton instantiation
private static final Object LOCK = new Object();
private static AppExecutors sInstance;
private final Executor diskIO;
private final Executor mainThread;
private final Executor networkIO;
private AppExecutors(Executor diskIO, Executor networkIO, Executor mainThread) {
this.diskIO = diskIO;
this.networkIO = networkIO;
this.mainThread = mainThread;
}
public static AppExecutors getInstance() {
if (sInstance == null) {
synchronized (LOCK) {
sInstance = new AppExecutors(Executors.newSingleThreadExecutor(),
Executors.newFixedThreadPool(3),
new MainThreadExecutor());
}
}
return sInstance;
}
public Executor diskIO() {
return diskIO;
}
public Executor mainThread() {
return mainThread;
}
public Executor networkIO() {
return networkIO;
}
private static class MainThreadExecutor implements Executor {
private Handler mainThreadHandler = new Handler(Looper.getMainLooper());
#Override
public void execute(#NonNull Runnable command) {
mainThreadHandler.post(command);
}
}
}

EDIT :
I implemented the code, but I am facing a few issues in the viewmodel class. For eg, the parameter in repository.insertSubtaskDetails(userDao); is userDao, but it actually it requires of type subtaskDetails.. some errors in the todo part as well. this is the code:
package com.example.taskmasterv3;
import android.app.Application;
import androidx.annotation.NonNull;
import androidx.lifecycle.AndroidViewModel;
import java.util.List;
public class ViewModel extends AndroidViewModel {
private Repository repository;
private List<SubtaskDetails> subtaskDetails;
public ViewModel(#NonNull Application application) {
super(application);
repository = new Repository(application);
subtaskDetails = repository.getSubtaskDetails();
}
public void insert(UserDao userDao) {
repository.insertSubtaskDetails(userDao);
}
public void delete(Todo todo) {
repository.deleteSubtaskDetails(userDao);
}
}
First make a Repository class and make an instance of your DAO
public class Repository {
private UserDAO userDAO;
private List<SubtaskDetails> subtaskDetails;
private Executor executor = Executors.newSingleThreadExecutor();
public Repository(Application application){
AppDatabase appDatabase = AppDatabase.getInstance(application);
userDAO = appDatabase.userDAO();
subtaskDetails = userDAO.getSubtaskDetailsList();
}
Then wrap it around your executor
public void insertSubtaskDetails(SubtaskDetails subtaskDetails){
executor.execute(new Runnable() {
#Override
public void run() {
userDAO.insertSubtaskDetails(subtaskDetails);
}
});
}// For inserting
public void deleteSubtaskDetails(SubtaskDetails subtaskDetails){
executor.execute(new Runnable() {
#Override
public void run() {
userDAO.deleteSubtaskDetails(subtaskDetails);
}
});
}// for deleting
Basically just wrap your DAO queries around the executor.
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;
}
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

if (dealerInventory.getQuantity() >= 0) {
id.setParentSalesPointLastStock(String.valueOf(dealerInventory.getQuantity()));
id.setParentSalesPointLastStockTakingDate(dealerInventory.getStockTakingDate());
}
} else {
id.setParentSalesPointLastStock(UiConstants.NA);
id.setParentSalesPointLastStockTakingDate(UiConstants.NA);
}
inventories.add(id); // do this
}
return inventories; // you are not assigning value anywhere;
}
You are not assigning value to the inventories in getInventoriesByItemDetails. I think you should add item through inventories.add(id);
Check it , Hope this help
