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(); } }
