跟教程写todoapplication

所需models和respository：

package com.example.to_do_application.data.models

enum class Priority {
 HIGH,
 MEDIUM,
 LOW
}

package com.example.to_do_application.data.models

import android.os.Parcelable
import androidx.room.Entity
import androidx.room.PrimaryKey
import kotlinx.parcelize.Parcelize

@Entity(tableName = "todo_table")
@Parcelize
data class ToDoData(
    @PrimaryKey(autoGenerate = true)
    var id: Int,
    var tile: String,
    var priority: Priority,
    var description: String
):Parcelable

package com.example.to_do_application.data.respository

import androidx.lifecycle.LiveData
import com.example.to_do_application.data.ToDoDao
import com.example.to_do_application.data.models.ToDoData

class ToDoRepository(private val toDoDao: ToDoDao) {
    val getAllData: LiveData<List<ToDoData>> = toDoDao.getAllData()
    val sortByHighPriority: LiveData<List<ToDoData>> = toDoDao.sortByHighPriority()
    val sortByLowhPriority: LiveData<List<ToDoData>> = toDoDao.sortByLowPriority()

    suspend fun insertData(toDoData: ToDoData){
        toDoDao.insertData(toDoData)
    }

    suspend fun updateData(toDoData: ToDoData){
        toDoDao.updateData(toDoData)
    }

    suspend fun deleteItem(toDoData: ToDoData){
        toDoDao.deleteItem(toDoData)
    }

    suspend fun deleteAll(){
        toDoDao.deleteAll()
    }

    fun searchDatabase(searchQuery: String): LiveData<List<ToDoData>>{
        return toDoDao.searchDatabase(searchQuery)
    }
}
