**Android响应式编程开发RxAndroid（6）：range**

range的参数意义，range(x,count),从x起，发射count个数据，例如代码：

package zhangphil.app;
    
    import android.app.Activity;
    import android.os.Bundle;
    import android.support.annotation.Nullable;
    import android.util.Log;
    
    import java.util.UUID;
    
    import io.reactivex.Observable;
    import io.reactivex.functions.Consumer;
    
    public class MainActivity extends Activity {
        private final String TAG = String.valueOf(UUID.randomUUID());
    
        @Override
        public void onCreate(@Nullable Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
    
            Observable.range(1, 5).subscribe(new Consumer<Integer>() {
    
                @Override
                public void accept(Integer integer) throws Exception {
                    Log.d(TAG, String.valueOf(integer));
                }
            });
        }
    }

运行结果输出：
