How to run two AsyncTasks at the same time so that they run at the same time?

Question

Android

There is a test program like this:

package codeasylum.ua.testasynctask;

import android.os.AsyncTask;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.TextView;

import java.util.concurrent.TimeUnit;

public class MainActivity extends AppCompatActivity {

    TextView tv1,tv2;
    int i,k;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        tv1 = (TextView) findViewById(R.id.task1);
        tv2 = (TextView) findViewById(R.id.task2);
        i =0;
        k = 0;
    }


    public void Start(View view) {
        new Task1().execute();
        new Task2().execute();
    }

    class Task1 extends AsyncTask<Void,Integer,Void>{

        @Override
        protected Void doInBackground(Void... voids) {
            int s = 0;
            while (s < 20){
                try {
                    TimeUnit.SECONDS.sleep(1);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                s++;
                i++;
                publishProgress(i);
            }
            return null;
        }

        @Override
        protected void onProgressUpdate(Integer... values) {
            super.onProgressUpdate(values[0]);
            tv1.setText(values[0]+"");
        }
    }
    class Task2 extends AsyncTask<Void,Integer,Void>{

        @Override
        protected Void doInBackground(Void... voids) {
                int s = 0;
                while (s < 20){
                    s++;
                    k+=2;
                    publishProgress(k);
                }

            return null;
        }
        @Override
        protected void onProgressUpdate(Integer... values) {
            super.onProgressUpdate(values[0]);
            tv2.setText(values[0]+"");
        }
    }
}

In it, I'm trying to make two AsyncTasks work at the same time. Those. I want the numbers in the TextView to update at the same time. How to achieve this with AsyncTask? Is it even possible? This could only be done through native Java threads, when I created a separate thread for each task.

Answer 1

Perhaps AsyncTaskCompat is what you need.

Answer 2

if you call a spade a spade, then the answer will be found by itself.
