How to integrate ViewModel with other Android components?

Integrating ViewModel with other Android components is essential for managing UI-related data in a lifecycle-conscious way. It allows data to survive configuration changes such as screen rotations. In this guide, we will illustrate how to integrate ViewModel with components like Activities and Fragments.

Example: Integrating ViewModel with Activity


        <?php
        // Create a ViewModel
        class MyViewModel extends ViewModel {
            private MutableLiveData<String> myData;

            public LiveData<String> getMyData() {
                if (myData == null) {
                    myData = new MutableLiveData<>();
                    loadData();
                }
                return myData;
            }

            private void loadData() {
                // Load data logic here
                myData.setValue("Hello, ViewModel!");
            }
        }

        // Inside an Activity
        public class MainActivity extends AppCompatActivity {
            private MyViewModel viewModel;

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

                viewModel = new ViewModelProvider(this).get(MyViewModel.class);
                observeViewModel();
            }

            private void observeViewModel() {
                viewModel.getMyData().observe(this, new Observer<String>() {
                    @Override
                    public void onChanged(String data) {
                        // Update UI with data
                        TextView textView = findViewById(R.id.textView);
                        textView.setText(data);
                    }
                });
            }
        }
        ?>
