My question is i want when i save or update any data in Database the app show the new data without refresh the activity like cricket score updates etc. Please give your suggestions.

Solution

  • It can be done using Room database.

    Databse class may look like this:

    open abstract class MDatabase : RoomDatabase() {
abstract fun dataDAO(): DataDAO

    }

    The Dao interface may look like the below:

    @Dao interface DataDAO {

    @Insert(onConflict = OnConflictStrategy.IGNORE)
fun saveData(dataEntity: DataEntity)

@Query(SELECT_ALL_DATA)
fun observeDB(): LiveData<Array<DataEntity>>

    }

    In the activity:

    database.dataDAO()
.observeDB()
.observe(this, Observer<Array<DataEntity>> {
   //Update UI
})
