public class LoginActivity extends AppCompatActivity implements View.OnClickListener {

    EditText email, password;
    Button btnSignIn, forgotpwdbtn, btnRegister;
    private FirebaseAuth auth;


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


        email = (EditText) findViewById(R.id.email);
        password = (EditText) findViewById(R.id.password);

        btnSignIn = (Button) findViewById(R.id.btnSignIn);
        forgotpwdbtn = (Button) findViewById(R.id.forgotpwdbtn);
        btnRegister = (Button) findViewById(R.id.btnRegister);

        btnSignIn.setOnClickListener(this);
        forgotpwdbtn.setOnClickListener(this);
        btnRegister.setOnClickListener(this);

        auth = FirebaseAuth.getInstance();
    }



    public void onClick(View view) {
        switch (view.getId()) {
            case R.id.btnSignIn:
                String email1 = email.getText().toString().trim();

                    @Override
                    public void onComplete(@NonNull Task<AuthResult> task) {

                        if (task.isSuccessful()) {
                            Toast.makeText(LoginActivity.this, "Authentication success", Toast.LENGTH_SHORT).show();
                            Intent mainIntent = new Intent(LoginActivity.this, MapsTrack.class);
                            startActivity(mainIntent);

                        } else {
                            Toast.makeText(LoginActivity.this, "Authentication failed." + task.getException(), Toast.LENGTH_SHORT).show();
                        }
                    }
                });
                break;
            case R.id.forgotpwdbtn:
                Intent intent = new Intent(LoginActivity.this, ForgotPasswordActivity.class);
                startActivity(intent);
                break;
            case R.id.btnRegister:
                Intent intentreg = new Intent(LoginActivity.this, Register.class);
                startActivity(intentreg);
                break;


        }
