Rxjava简单使用

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.util.Log;

import io.reactivex.Observable;
import io.reactivex.ObservableEmitter;
import io.reactivex.ObservableOnSubscribe;
import io.reactivex.Observer;
import io.reactivex.annotations.NonNull;
import io.reactivex.disposables.Disposable;


public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        executeAsyncTask();//That do not influence other steps
        //Step one
        //Step two
    }

    private void executeAsyncTask() {
        //Observable#create方法创建一个异步任务
        Observable.create(new ObservableOnSubscribe<Integer>() {
                    @Override
                    public void subscribe(@NonNull ObservableEmitter<Integer> e) throws Exception {
                       e.onComplete();
                    }
                })
                .subscribe(new Observer<Integer>() {
                    @Override
                    public void onSubscribe(@NonNull Disposable d) {
                    }

                    @Override
                    public void onNext(@NonNull Integer integer) {
                    }

                    @Override
                    public void onError(@NonNull Throwable e) {
                    }

                    @Override
                    public void onComplete() {
                    }
                });

    }
    implementation "io.reactivex.rxjava2:rxjava:2.2.10"
    implementation "io.reactivex.rxjava2:rxandroid:2.0.2"
