**RxJava/RxAndroid : interval**

import android.support.v7.app.AppCompatActivity;
    import android.os.Bundle;
    import android.util.Log;
    
    import java.util.concurrent.TimeUnit;
    
    import io.reactivex.Observable;
    import io.reactivex.android.schedulers.AndroidSchedulers;
    import io.reactivex.observers.DisposableObserver;
    import io.reactivex.schedulers.Schedulers;
    
    public class MainActivity extends AppCompatActivity {
        private String TAG = "输出";
    
        private DisposableObserver mDisposableObserver = new DisposableObserver<Long>() {
            @Override
            public void onNext(Long l) {
                Log.d(TAG, "onNext:" + l);
            }
    
            @Override
            public void onComplete() {
                Log.d(TAG, "onComplete");
            }
    
            @Override
            public void onError(Throwable e) {
                Log.e(TAG, e.toString(), e);
            }
        };
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
    
            Observable.interval(0, 3, TimeUnit.SECONDS)
                    .subscribeOn(Schedulers.io())
                    .observeOn(AndroidSchedulers.mainThread())
                    .subscribeWith(mDisposableObserver);
        }
    }

output:
