We will try to make a TechVidvan Employee Tracker Application using Android. We will apply our Android knowledge in a simple yet exciting way to create the application.

About Android Employee Tracker Application

An Employee Tracker Application helps organisations in maintaining records of their employees. It provides a simple and easy way to manage and track employee details, attendance, and performance. We can also determine the employee’s location to see if they are working correctly or roaming around.

We will learn to build an Employee Tracker Application using Android Studio (Java and XML). Our application will have the following features:

You can add as many employee records as needed.
You can edit the employee records.
You can view the location of each employee.

import com.google.android.material.button.MaterialButton;

public class LandingScreenActivity extends BaseActivity {
   MaterialButton btnEmployer;
   MaterialButton btnEmployee;

   private FusedLocationProviderClient fusedLocationClient;
   private static final int LOCATION_PERMISSION_REQUEST_CODE = 1;

   @Override
   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.landing_screen);

       // Initialize class-level variables
       btnEmployer = findViewById(R.id.landingEmployerButton);
       btnEmployee = findViewById(R.id.landingEmployeeButton);

       fusedLocationClient = LocationServices.getFusedLocationProviderClient(this);

       requestLocationPermission();
       changeLayout();
   }
  
   public void changeLayout() {
       View.OnClickListener handler = new View.OnClickListener() {
           public void onClick(View v) {
               if (v == btnEmployer) {
                   Intent intentMain = new Intent(LandingScreenActivity.this, EmployerViewActivity.class);
                   LandingScreenActivity.this.startActivity(intentMain);
               }
               if (v == btnEmployee) {
                   Intent intentMain = new Intent(LandingScreenActivity.this, EmployeeViewActivity.class);
                   LandingScreenActivity.this.startActivity(intentMain);
               }
           }
       };

       btnEmployee.setOnClickListener(handler);

           ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, LOCATION_PERMISSION_REQUEST_CODE);
       } else {
           getLocation();
       }
   }

   private void getLocation() {
       if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
           return;
       }
       Task<android.location.Location> locationResult = fusedLocationClient.getLastLocation();
       locationResult.addOnSuccessListener(this, new OnSuccessListener<android.location.Location>() {
           @Override
           public void onSuccess(android.location.Location location) {
               if (location != null) {

           }
       });
   }

   @Override
   public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
       super.onRequestPermissionsResult(requestCode, permissions, grantResults);
       if (requestCode == LOCATION_PERMISSION_REQUEST_CODE) {
           if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
               getLocation();
           }
       }
   }
}

Explanation:

First, we include the necessary Android libraries and Google Location Services libraries, and define LandingScreenActivity, which extends BaseActivity, which contains our toolbar.
We define two MaterialButtons: FusedLocationProviderClient, which gets the location, and LOCATION_PERMISSION_REQUEST_CODE, which handles location permission request results.
We created OnCreate() to initialise UI components and request location permission. It also connects UI buttons to the corresponding variables.
changeLayout() is used to define what happens when the employer or employee button is clicked. setOnClickListener sets the click listener on buttons, and Intent helps us navigate to the respective activity.
requestLocationPermission() checks if location permission is granted. If not, request permission. getLocation() retrieves the location if permissions are granted. The OnSuccessListener handles the location result.

import java.util.Map;

public class EmployeeViewActivity extends AppCompatActivity {

   private EditText editTextName;
   private EditText editTextId;
   private MaterialButton btnIn;
   private MaterialButton btnOut;
   private FirebaseFirestore db;

   @Override
   protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       overridePendingTransition(R.anim.fade_in, R.anim.fade_out);
       setContentView(R.layout.employee_view);

       editTextName = findViewById(R.id.editTextName);

       db = FirebaseFirestore.getInstance();

       changeLayout();
   }

   // Transition between layouts
   public void changeLayout() {
       View.OnClickListener handler = new View.OnClickListener() {
           public void onClick(View v) {
               if (v == btnIn) {
                   saveEmployeeData();
               }
               if (v == btnOut) {
                   Intent intentMain = new Intent(EmployeeViewActivity.this, LandingScreenActivity.class);
                   EmployeeViewActivity.this.startActivity(intentMain);
               }
           }
       };

       btnIn.setOnClickListener(handler);
       btnOut.setOnClickListener(handler);
   }

   public void saveEmployeeData() {
       String name = editTextName.getText().toString();
       String id = editTextId.getText().toString();

       if (name.isEmpty() || id.isEmpty()) {
           Toast.makeText(this, "Please enter both name and ID", Toast.LENGTH_SHORT).show();
           return;
       }

       String checkInTime = getCurrentTime(); // Get current time as check-in time

       Map<String, Object> employee = new HashMap<>();
       employee.put("name", name);
       employee.put("id", id);
       employee.put("checkInTime", checkInTime); 
       employee.put("attendance", "Present");

       db.collection("employees")
               .add(employee)
               .addOnSuccessListener(new OnSuccessListener<DocumentReference>() {
                   @Override
                   public void onSuccess(DocumentReference documentReference) {
                       Toast.makeText(EmployeeViewActivity.this, "Employee data saved", Toast.LENGTH_SHORT).show();
                       Intent intent = new Intent(EmployeeViewActivity.this, WelcomeActivity.class);
                       intent.putExtra("EMPLOYEE_NAME", name);
                       intent.putExtra("EMPLOYEE_ID", id);
                       startActivity(intent);
                   }
               })
               .addOnFailureListener(new OnFailureListener() {
                   @Override
                   public void onFailure(@NonNull Exception e) {
                       Toast.makeText(EmployeeViewActivity.this, "Error saving data", Toast.LENGTH_SHORT).show();
                   }
               });
   }

   private String getCurrentTime() {
       SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
       return sdf.format(new Date());
   }
}

Explanation:

First, we import the necessary Android libraries and the Firebase Firestore libraries and define EmployeeViewActivity. We define 2 Input Fields, 2 Material buttons and a Firestore instance to interact with the Firestore database.
We define the onCreate() to initialize UI components and set up layout transitions and click listeners. It also connects the UI elements to the corresponding variables.
changeLayout() is used to define what happens when the check-in or check-out button is clicked. Intent navigates back to LandingScreenActivity when the check-out button is clicked.
saveEmployeeData() saves employee data to Firestore. It retrieves Name and ID from the input fields. Gets the current check-in time and adds the data to the employees collection in Firestore.
getCurrentTime() returns the current date and time in the given format.

3. EmployerViewActivity.java

package com.example.employeetrackerapplication;

import android.content.Intent;
import android.graphics.Typeface;
import android.os.Bundle;
import android.view.View;
import android.widget.RadioButton;
import android.widget.RadioGroup;

import com.google.android.gms.tasks.Task;
import com.google.android.material.button.MaterialButton;
import com.google.firebase.firestore.DocumentSnapshot;
import com.google.firebase.firestore.FirebaseFirestore;
import com.google.firebase.firestore.QuerySnapshot;

public class EmployerViewActivity extends AppCompatActivity {

   private RadioGroup employerViewRadioGroup;
   private MaterialButton employerViewButton;
   private MaterialButton employerViewExitButton;
   private FirebaseFirestore db;

   @Override
   protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.employer_view);

       employerViewRadioGroup = findViewById(R.id.employerViewRadioGroup);
       employerViewButton = findViewById(R.id.employerViewButton);
       employerViewExitButton = findViewById(R.id.employerViewExitButton);

       db = FirebaseFirestore.getInstance();

       employerViewButton.setOnClickListener(new View.OnClickListener() {
           @Override
           public void onClick(View v) {
               int selectedId = employerViewRadioGroup.getCheckedRadioButtonId();
               RadioButton selectedEmployee = findViewById(selectedId);

               if (selectedEmployee != null) {
                   Intent intent = new Intent(EmployerViewActivity.this, EmployeeLocationActivity.class);
                  
                   intent.putExtra("EMPLOYEE_ID", selectedEmployee.getTag().toString());
                   startActivity(intent);
               }
           }
       });

       employerViewExitButton.setOnClickListener(new View.OnClickListener() {
           @Override
           public void onClick(View v) {
               finish();
           }
       });

       fetchEmployeeData();
   }

   private void fetchEmployeeData() {
       db.collection("employees").get().addOnCompleteListener(new OnCompleteListener<QuerySnapshot>() {
           @Override
           public void onComplete(@NonNull Task<QuerySnapshot> task) {
               if (task.isSuccessful()) {
                   QuerySnapshot querySnapshot = task.getResult();
                   if (querySnapshot != null) {
                       for (DocumentSnapshot document : querySnapshot.getDocuments()) {
                           String name = document.getString("name");
                           String id = document.getString("id");

                           if (name != null && id != null) {
                               addRadioButton(name, id);
                           }
                       }
                   }
               } else {
                   Toast.makeText(EmployerViewActivity.this, "Error fetching employee data", Toast.LENGTH_SHORT).show();
               }
           }
       });
   }

   private void addRadioButton(String name, String id) {
       RadioButton radioButton = new RadioButton(this);
       radioButton.setText(name);
       radioButton.setTag(id);
       radioButton.setTextColor(getResources().getColor(android.R.color.black));
       radioButton.setTextSize(20f);
       radioButton.setTypeface(radioButton.getTypeface(), Typeface.BOLD);

       radioButton.setButtonTintList(getResources().getColorStateList(android.R.color.black));

       employerViewRadioGroup.addView(radioButton);
   }
}

Explanation:

First, we import the necessary Android libraries and the Firebase Firestore libraries and define EmployerViewActivity. We define a group of Radio buttons, 2 Material buttons and a Firestore instance to interact with the Firestore database.
onCreate() is used to initialize UI components and set up click listeners. It also connects the UI elements to the corresponding variables.
employerViewButton.setOnClickListener helps in navigating to EmployeeLocationActivity when an employee is selected.
fetchEmployeeData() fetches employee data from the employees collection in Firestore. It calls addRadioButton() to add each employee as a radio button in the RadioGroup.
addRadioButton() adds a radio button for each employee. It creates a new RadioButton instance and sets the text and tag to the employee’s name and ID.

           e.printStackTrace();
           Toast.makeText(this, "Permission denied", Toast.LENGTH_SHORT).show();
       }
   }
}

Explanation:

We include the necessary Android libraries, Google Location services, and Firebase Firestore libraries, and we define EmployeeLocationActivity.
We define TextViews for displaying important information, a button, a FusedLocationProviderClient for accessing location services, and a Firestore instance.
onCreate() initializes UI components and sets up the necessary instances for location services and Firestore. getIntent().getStringExtra() retrieves the employee ID passed from the previous activity.
fetchEmployeeData() fetches employee data from the employees collection in Firestore based on the employee ID. It retrieves the first result matching the query and extracts employee details.
fetchLocation() is used to fetch the device’s location using the FusedLocationProviderClient and updates the latitude and longitude.
Logout() helps in logging out, and Intent navigates us back to LandingScreen.
