WorkManager Worker의 Input, Output data 설정

Data.Builder로 데이터 생성 후 request에 setInputData로 넘겨준다

 

Woker의 데이터를 it.outputData를 사용하여 받을 수 있다

package com.anushka.workmanagerdemo1

import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.widget.Toast
import androidx.lifecycle.Observer
import androidx.work.*
import kotlinx.android.synthetic.main.activity_main.*

class MainActivity : AppCompatActivity() {

    companion object{
    const val KEY_COUNT_VALUE = "key_count"
    }

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        button.setOnClickListener {
            setOneTimeWorkRequest()
        }
    }

    private fun setOneTimeWorkRequest() {

        val workManager = WorkManager.getInstance(applicationContext)

        val data: Data = Data.Builder()
            .putInt(KEY_COUNT_VALUE,125)
            .build()
        val constraints = Constraints.Builder()
            .setRequiresCharging(true)
            .build()

        val uploadRequest = OneTimeWorkRequest.Builder(UploadWorker::class.java)
            .setConstraints(constraints)
            .setInputData(data)
            .build()
        workManager.enqueue(uploadRequest)
        workManager.getWorkInfoByIdLiveData(uploadRequest.id)
            .observe(this, Observer {
                textView.text = it.state.name
                if(it.state.isFinished){
                 val data = it.outputData
                 val message = data.getString(UploadWorker.KEY_WORKER)
                    Toast.makeText(applicationContext,message,Toast.LENGTH_LONG).show()
                }
            })


    }
}

 

Worker에서 inputData 를 사용하여 데이터 가져오기

 

Woker에서 Data.Builder()를 사용하여 데이터 생성후 Result에 포함시켜 호출한 Request에서 사용

package com.anushka.workmanagerdemo1

import android.content.Context
import android.util.Log
import androidx.work.Data
import androidx.work.Worker
import androidx.work.WorkerParameters
import java.lang.Exception
import java.text.SimpleDateFormat
import java.util.*

class UploadWorker(context: Context,params:WorkerParameters) : Worker(context,params) {

    companion object{
        const val KEY_WORKER = "key_worker"
    }

    override fun doWork(): Result {
        try {
            val count = inputData.getInt(MainActivity.KEY_COUNT_VALUE,0)
            for (i in 0 until count) {
                Log.i("MYTAG", "Uploading $i")
            }

            val time = SimpleDateFormat("dd/M/yyyy hh:mm:ss")
            val currentDate = time.format(Date())

            val outPutData = Data.Builder()
                .putString(KEY_WORKER,currentDate)
                .build()

            return Result.success(outPutData)
        } catch (e:Exception){
            return Result.failure()
        }
    }
}
