我正在使用LeakCanary 1.3.1-SNAPSHOT.我发现有关ViewTreeObserver.OnScrollChangedListener设置的泄漏,我修复了它,如下面的代码:

  private ViewTreeObserver.OnScrollChangedListener scrollViewChangeListener;

  @Override protected void onFinishInflate() {
      super.onFinishInflate();
      ButterKnife.inject(this);
      scrollViewChangeListener = new ViewTreeObserver.OnScrollChangedListener() {
      @Override public void onScrollChanged() {
        EventDetailsView.this.onScrollChanged(scrollView.getScrollY());
      }
    };
      scrollView.getViewTreeObserver()
        .addOnScrollChangedListener(scrollViewChangeListener);
  }
  @Override public void onDetachedFromWindow() {
      super.onDetachedFromWindow();
      scrollView.getViewTreeObserver().removeOnScrollChangedListener(scrollViewChangeListener);
  }

然而,LeakCanary仍然将其报告为泄漏,任何想法为什么？
