android - “SwipeRefreshLayout”刷新 web 视图只工作一次

Question

SwipeRefreshLayout 只能工作一次，如何解决这个问题：

 <androidx.swiperefreshlayout.widget.SwipeRefreshLayout
        android:id="@+id/swipeContainer"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior">

 <RelativeLayout
            android:id="@+id/nonVideoLayout"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:windowSoftInputMode="adjustResize">

            <ProgressBar
                android:id="@+id/progressbar"
                style="@style/Widget.AppCompat.ProgressBar.Horizontal"
                android:layout_width="match_parent"
                android:layout_height="4dp"
                android:scaleY="4.0" />
          <WebView
                android:id="@+id/webid"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:layout_marginTop="5dp"
                android:windowSoftInputMode="adjustResize"
                app:layout_constraintDimensionRatio="1" />

        </RelativeLayout>



    </androidx.swiperefreshlayout.widget.SwipeRefreshLayout>


</RelativeLayout>

        );

        mySwipeRefreshLayout.getViewTreeObserver().removeOnScrollChangedListener(mOnScrollChangedListener);

        mySwipeRefreshLayout.getViewTreeObserver().addOnScrollChangedListener(mOnScrollChangedListener =
                new ViewTreeObserver.OnScrollChangedListener() {
                    @Override

                        if (webViewid.getScrollY() == 0)
                            mySwipeRefreshLayout.setEnabled(true);
                        else
                            mySwipeRefreshLayout.setEnabled(false);

                    }
                });


    }
