BaseDao

You can use this Base if you using Room as your local database.

• Make Base Class

interface BaseDao<T> {

    @Insert(onConflict = OnConflictStrategy.REPLACE)
    fun insert(obj: T) : Long

    @Insert(onConflict = OnConflictStrategy.IGNORE)
    fun insertIgnore(obj: T) : Long

    @Insert(onConflict = OnConflictStrategy.REPLACE)
    fun insert(vararg obj: T)

    @Insert(onConflict = OnConflictStrategy.REPLACE)
    fun insertAll(objs: List<T>): List<Long>

    @Insert(onConflict = OnConflictStrategy.IGNORE)
    fun insertIgnoreAll(objs: List<T>): List<Long>

    @Update
    fun update(obj: T)

    @Update
    fun updateAll(objs: List<T>): Int

    @Delete
    fun delete(obj: T)

    @Delete
    fun deleteAll(objs: List<T>): Int

}

• Entity Class

@Entity(tableName = "dummy")
data class DummyTable(

    @PrimaryKey(autoGenerate = true)
    val id: Int? = null,

    @ColumnInfo(name = "field1")
    val field1: String? = null
)

• Use Base Class

@Dao
abstract class DummyDao: BaseDao<DummyTable> {

    @Query("SELECT * FROM dummy")
    abstract fun getAll(): List<DummyTable>

    @Query("DELETE FROM dummy")
    abstract fun truncateData()

    @Query("SELECT COUNT(id) FROM dummy")
    abstract fun getRowCount(): Int
}

BaseListResponse

You cal use this Base if you using Retrofit on your project as your Http Client.

• JSON response example

{
   "status":"1",
   "message":"Success dapat data",
   "total":10,
   "data":[
      {
         "id":1,
         "name":"Zein"
      },
      {
         "id":2,
         "name":"GZeinNumer"
      }
   ]
}

• Make Base Class

data class BaseListResponse<T>(@SerializedName("status") @Expose val status: String,
                               @SerializedName("message") @Expose val message: String?,
                               @SerializedName("total") @Expose val total: Int?,
                               @SerializedName("data") @Expose val data: List<T>?)

• Make Model Class

data class DataItem(@SerializedName("id") @Expose val id: int ,
                    @SerializedName("name") @Expose val name: String)

• Use Base Class

interface ApiService {
    @GET("/users/{id}")
    fun getUserCall(@Body dataItem: DataItem): Call<BaseListResponse<DataItem>>
}

BaseObjectResponse

You can use this Base if you using Retrofit on your project as your Http Client.

• JSON response example

{
   "status":"1",
   "message":"Success dapat data",
   "total":10,
   "data":{
      "id":2,
      "name":"GZeinNumer"
   }
}

• Make Base Class

data class BaseObjectResponse<T>(@SerializedName("status") @Expose val status: String,
                                 @SerializedName("message") @Expose val message: String?,
                                 @SerializedName("data") @Expose val data: T?)

• Make Model Class

data class DataItem(@SerializedName("id") @Expose val id: int ,
                    @SerializedName("name") @Expose val name: String)

• Use Base Class

interface ApiService {
    @GET("/users/{id}")
    fun getUserCall(@Body dataItem: DataItem): Call<BaseObjectResponse<DataItem>>
}

BaseActivity

• Make Base Class

abstract class BaseActivity : AppCompatActivity() {

    private val TAG = "BaseActivity"
    
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
    }

    protected fun onShowLoading() {
    
    }

}

• Use Base Class

class MainActivity : BaseActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        
        onShowLoading()
    }
}

BaseResource

data class BaseResource<T> private constructor(val status: BaseResourceStatus,
                                               val data: T?,
                                               val message: String?){
    enum class BaseResourceStatus {
        STATUS_1_SUCCESS,
        STATUS_2_ERROR,
        STATUS_3_EMPTY,
        STATUS_4_INFO,
        STATUS_5_LOGOUT,
        STATUS_6_LOADING
    }

    companion object {
        fun <T> success(msg: String,data: T): BaseResource<T> {
            return BaseResource(BaseResourceStatus.STATUS_1_SUCCESS, data, msg)
        }

        fun <T> error(msg: String): BaseResource<T> {
            return BaseResource(BaseResourceStatus.STATUS_2_ERROR, null, msg)
        }

        fun <T> empty(msg: String): BaseResource<T> {
            return BaseResource(BaseResourceStatus.STATUS_3_EMPTY, null, msg)
        }

        fun <T> info(msg: String): BaseResource<T> {
            return BaseResource(BaseResourceStatus.STATUS_4_INFO, null, msg)
        }

        fun <T> logout(): BaseResource<T> {
            return BaseResource(BaseResourceStatus.STATUS_5_LOGOUT, null, null)
        }

        fun <T> loading(): BaseResource<T> {
            return BaseResource(BaseResourceStatus.STATUS_6_LOADING, null, null)
        }
    }
}
