Lifecycle components, Retrofit2 and Room database. 3 | 4 | In this demo, I have covered **Mediator Live data, Mutable live data, Observable, Observers, Retrofit and Room using same POJO.** 5 | 6 | ## APP UI 7 | ![App UI](https://github.com/martinraj/MVVM-architecture-lifecycle-components-and-Room-database-project/blob/master/screenshots%20and%20demo/Screenshot_20181205-024745.png) ![](https://github.com/martinraj/MVVM-architecture-lifecycle-components-and-Room-database-project/blob/master/screenshots%20and%20demo/Screenshot_20181205-024753.png) ![](https://github.com/martinraj/MVVM-architecture-lifecycle-components-and-Room-database-project/blob/master/screenshots%20and%20demo/Screenshot_20181205-024829.png) 8 | 9 | ## Room and Retrofit using same Model 10 | 11 | I have used same models for Room and Retrofit2 library as both are configured using annotaions. 12 | 13 | ``` 14 | @Entity 15 | public class FoodDetails { 16 | 17 | @PrimaryKey //Room annotation 18 | @SerializedName("item_name") //Retrofit annotation 19 | @Expose 20 | @NonNull 21 | private String name; 22 | 23 | @SerializedName("item_price") 24 | @Expose 25 | private Double price; 26 | 27 | @SerializedName("average_rating") 28 | @Expose 29 | private Double rating; 30 | 31 | @SerializedName("image_url") 32 | @Expose 33 | private String imageUrl; 34 | 35 | @SerializedName("item_quantity") 36 | @Expose 37 | private Integer quantity = 0; 38 | 39 | // For Retrofit 40 | public FoodDetails(@NonNull String name, Double price, Double rating, String imageUrl,Integer quantity) { 41 | this.name = name; 42 | this.price = price; 43 | this.rating = rating; 44 | this.imageUrl = imageUrl; 45 | this.quantity = quantity; 46 | } 47 | 48 | // Getters and Setters for Room 49 | @NonNull 50 | public String getName() { 51 | return name; 52 | } 53 | 54 | public void setName(@NonNull String name) { 55 | this.name = name; 56 | } 57 | 58 | public Double getPrice() { 59 | return price; 60 | } 61 | 62 | public void setPrice(Double price) { 63 | this.price = price; 64 | } 65 | 66 | public Double getRating() { 67 | return rating; 68 | } 69 | 70 | public void setRating(Double rating) { 71 | this.rating = rating; 72 | } 73 | 74 | public String getImageUrl() { 75 | return imageUrl; 76 | } 77 | 78 | public void setImageUrl(String imageUrl) { 79 | this.imageUrl = imageUrl; 80 | } 81 | 82 | public Integer getQuantity() { 83 | return quantity; 84 | } 85 | 86 | public void setQuantity(Integer quantity) { 87 | this.quantity = quantity; 88 | } 89 | } 90 | ``` 91 | 92 | ## Sorting list elements in Room Database and observing using Mediator Live Data 93 | 94 | Sorting of food items is done based on Pricing and rating. I have used Mediator Live data to observe same types of Live Data from different db queries. We are going to expose Mediator Live Data to UI which will observe data changes from other two Live Data. 95 | 96 | ``` 97 | ...\ 98 | public class FoodViewModel extends AndroidViewModel { 99 | MediatorLiveData> foodDetailsMediatorLiveData = new MediatorLiveData<>(); 100 | 101 | private LiveData> foodDetailsLiveDataSortPrice; 102 | private LiveData> foodDetailsLiveDataSortRating; 103 | private AppDatabase db; 104 | private static String DEFAULT_SORT = ACTION_SORT_BY_PRICE; 105 | 106 | public FoodViewModel(@NonNull Application application) { 107 | super(application); 108 | init(); 109 | } 110 | 111 | private void init() { 112 | db = AppDatabase.getDatabase(getApplication().getApplicationContext()); 113 | subscribeToFoodChanges(); 114 | } 115 | 116 | private void subscribeToFoodChanges() { 117 | if(DEFAULT_SORT.equals(ACTION_SORT_BY_PRICE)){ 118 | foodDetailsLiveDataSortPrice = db.foodDetailsDao().getFoodsByPrice(); 119 | foodDetailsMediatorLiveData.addSource(foodDetailsLiveDataSortPrice, new Observer>() { 120 | @Override 121 | public void onChanged(@Nullable List foodDetails) { 122 | foodDetailsMediatorLiveData.setValue(foodDetails); 123 | } 124 | }); 125 | }else if(DEFAULT_SORT.equals(ACTION_SORT_BY_RATING)){ 126 | foodDetailsLiveDataSortRating = db.foodDetailsDao().getFoodsByRating(); 127 | foodDetailsMediatorLiveData.addSource(foodDetailsLiveDataSortRating, new Observer>() { 128 | @Override 129 | public void onChanged(@Nullable List foodDetails) { 130 | foodDetailsMediatorLiveData.setValue(foodDetails); 131 | } 132 | }); 133 | } 134 | } 135 | 136 | ...\ 137 | ``` 138 | 139 | Manually we are triggering observers by using **foodDetailsMediatorLiveData.setValue(foodDetails);** 140 | 141 | ## Room DB query for Sorting food items 142 | ``` 143 | @Dao 144 | public interface FoodDetailsDao { 145 | 146 | ...\ 147 | 148 | @Query("SELECT * FROM fooddetails ORDER BY price ASC") 149 | LiveData> getFoodsByPrice(); 150 | 151 | @Query("SELECT * FROM fooddetails ORDER BY rating DESC") 152 | LiveData> getFoodsByRating(); 153 | 154 | ...\ 155 | } 156 | ``` 157 | 158 | ## Observing data changes in Activity/Fragment 159 | 160 | We have to create observers for live data. Only then if any data is changed, observers will be notified with updated data by ViewModel. 161 | 162 | ``` 163 | ...\ 164 | 165 | @Override 166 | protected void onCreate(Bundle savedInstanceState) { 167 | .../ 168 | 169 | // Define viewmodel 170 | FoodViewModel foodViewModel = ViewModelProviders.of(this).get(FoodViewModel.class); 171 | 172 | // Define Observer with actions to be done after update 173 | Observer> foodMenuObserver = new Observer>() { 174 | @Override 175 | public void onChanged(@Nullable List foodDetails) { 176 | if(foodDetails!=null){ 177 | foodListAdapter.setData(foodDetails); 178 | foodListAdapter.notifyDataSetChanged(); 179 | runLayoutAnimation(foodList); 180 | }else{ 181 | Log.e("Food details","null"); 182 | } 183 | } 184 | }; 185 | 186 | // set observer to watch for data changes 187 | foodViewModel.getFoodDetailsMutableLiveData().observe(this, foodMenuObserver); 188 | 189 | .../ 190 | } 191 | 192 | ...\ 193 | 194 | ``` 195 | ## Retrofit to get data from server 196 | 197 | We have used Retrofit to get data from Rest API and updating db using Room in Intent Service 198 | 199 | ``` 200 | public interface YummyAPIServices { 201 | 202 | @GET("/data.json") 203 | Call> getFoodData(); 204 | } 205 | 206 | ``` 207 | 208 | ``` 209 | public class FoodRepository { 210 | 211 | private static FoodRepository instance; 212 | private static final String TAG = "FoodRepository"; 213 | 214 | private YummyAPIServices yummyAPIServices = APIClient.getClient().create(YummyAPIServices.class); 215 | 216 | public MutableLiveData getFoodMenu(final Context context){ 217 | 218 | final MutableLiveData isFoodCallOngoing = new MutableLiveData<>(); 219 | isFoodCallOngoing.setValue(true); 220 | 221 | yummyAPIServices.getFoodData().enqueue(new Callback>() { 222 | @Override 223 | public void onResponse(Call> call, Response> response) { 224 | if(response.isSuccessful()) { 225 | new SaveFoodMenu(AppDatabase.getDatabase(context), response.body()).execute(); 226 | isFoodCallOngoing.setValue(false); // on success we are updating empty mutable live data with new food menus 227 | }else{ 228 | Log.e(TAG,"response not successful"); 229 | } 230 | } 231 | 232 | @Override 233 | public void onFailure(Call> call, Throwable t) { 234 | Log.e(TAG,t.toString()); 235 | } 236 | }); 237 | return isFoodCallOngoing; // returns empty mutable live data 238 | } 239 | 240 | public static FoodRepository getInstance() { 241 | if(instance == null){ 242 | synchronized (FoodRepository.class){ 243 | if(instance == null){ 244 | instance = new FoodRepository(); 245 | } 246 | } 247 | } 248 | return instance; 249 | } 250 | } 251 | ``` 252 | ## API Client for Retrofit 253 | 254 | We are using singleton to get Retrofit client. 255 | ``` 256 | public class APIClient { 257 | 258 | private static final String BASE_URL = "YOUR_SERVER_BASE_URL"; 259 | private static Retrofit retrofit = null; 260 | 261 | 262 | public static Retrofit getClient() { 263 | if (retrofit==null) { 264 | retrofit = new Retrofit.Builder() 265 | .baseUrl(BASE_URL) 266 | .addConverterFactory(GsonConverterFactory.create()) 267 | .build(); 268 | } 269 | return retrofit; 270 | } 271 | 272 | } 273 | ``` 274 | 275 | ## Project Structure 276 | 277 | This is the overall project structure of this project. 278 | 279 | 280 | ![Project
