MotionLayout: MotionScene OnClick overrides setOnClickListener

Question

I\'m just starting to play with MotionLayout. I have defined an activity layout using MotionLayout that uses a MotionScene to hide and sh

You can implement MotionLayout.TransitionListener to handler event when transition.

public class LoginActivity extends AppCompatActivity implements MotionLayout.TransitionListener {
private static final String TAG = "LoginActivity";
private FirebaseAuth mAuth;
private LoginLayoutBinding binding;

@SuppressLint("ClickableViewAccessibility")
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    binding = LoginLayoutBinding.inflate(getLayoutInflater());
    setContentView(binding.getRoot());

    // initialize the FirebaseAuth instance.
    mAuth = FirebaseAuth.getInstance();
    binding.getRoot().addTransitionListener(this);
}


@Override
public void onStart() {
    super.onStart();
    // Check if user is signed in (non-null) and update UI accordingly.
    FirebaseUser currentUser = mAuth.getCurrentUser();
    updateUI(currentUser);
}

private void updateUI(FirebaseUser currentUser) {
    hideProgressBar();
    if (currentUser != null) {
        Intent intent = new Intent(LoginActivity.this, MainActivity.class);
        startActivity(intent);
        finish();
    }
}

private void hideProgressBar() {
    binding.progressBar2.setVisibility(View.GONE);
}

private void createAccount(String email, String password) {
    mAuth.createUserWithEmailAndPassword(email, password)
            .addOnCompleteListener(this, new OnCompleteListener() {
                @Override
                public void onComplete(@NonNull Task task) {
                    if (task.isSuccessful()) {
                        // Sign in success, update UI with the signed-in user's information
                        Log.d(TAG, "createUserWithEmail:success");
                        FirebaseUser user = mAuth.getCurrentUser();
                        updateUI(user);
                    } else {
                        // If sign in fails, display a message to the user.
                        Log.w(TAG, "createUserWithEmail:failure", task.getException());
                        Toast.makeText(LoginActivity.this, "Authentication failed.",
                                Toast.LENGTH_SHORT).show();
                        updateUI(null);
                    }
                }
            });
}

private void signIn(String email, String password) {
    mAuth.signInWithEmailAndPassword(email, password)
            .addOnCompleteListener(this, new OnCompleteListener() {
                @Override
                public void onComplete(@NonNull Task task) {
                    if (task.isSuccessful()) {
                        // Sign in success, update UI with the signed-in user's information
                        Log.d(TAG, "signInWithEmail:success");
                        FirebaseUser user = mAuth.getCurrentUser();
                        updateUI(user);
                    } else {
                        // If sign in fails, display a message to the user.
                        Log.w(TAG, "signInWithEmail:failure", task.getException());
                        Toast.makeText(LoginActivity.this, "Authentication failed.",
                                Toast.LENGTH_SHORT).show();
                        updateUI(null);
                    }
                }
            });
}


@Override
public void onTransitionStarted(MotionLayout motionLayout, int startId, int endId) {

}

@Override
public void onTransitionChange(MotionLayout motionLayout, int startId, int endId, float progress) {

}

@Override
public void onTransitionCompleted(MotionLayout motionLayout, int currentId) {
    if (currentId==R.id.end){
        binding.btnLogin.setText(R.string.sign_up);
        binding.textView3.setEnabled(false);
        binding.textView2.setEnabled(true);
    }else {
        binding.btnLogin.setText(R.string.login);
        binding.textView2.setEnabled(false);
        binding.textView3.setEnabled(true);
    }

}

@Override
public void onTransitionTrigger(MotionLayout motionLayout, int triggerId, boolean positive, float progress) {

}

}
