RxJava2 / RxAndroid2操作符skip

顾名思义，skip跳过，例如：
package zhangphil.app;

import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;

import io.reactivex.Observable;
import io.reactivex.android.schedulers.AndroidSchedulers;
import io.reactivex.disposables.CompositeDisposable;
import io.reactivex.observers.DisposableObserver;
import io.reactivex.schedulers.Schedulers;

public class MainActivity extends AppCompatActivity {
private final String TAG = getClass().getSimpleName();
private CompositeDisposable mCompositeDisposable = null;

@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mCompositeDisposable = new CompositeDisposable();

test();
}

private void test() {
DisposableObserver disposableObserver = new DisposableObserver<Integer>() {
@Override
public void onNext(Integer i) {
Log.d(TAG, "#####开始#####");
Log.d(TAG + "数据", String.valueOf(i));
Log.d(TAG, "#####结束#####");
}

@Override
public void onComplete() {
Log.d(TAG, "onComplete");
}

@Override
public void onError(Throwable e) {
Log.e(TAG, e.toString(), e);
}
};

mCompositeDisposable.add(getObservable()
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.skip(5)
.subscribeWith(disposableObserver));
}

private Observable<Integer> getObservable() {
return Observable.range(0, 10);
}

@Override
protected void onDestroy() {
super.onDestroy();

// 如果退出程序，就清除后台任务
mCompositeDisposable.clear();
}
}
