放大视图的TouchDelegate

Question

我有一个Android视图，想要将其TouchDelegate的宽度增大。

     private void expandDiscTouchArea() {
        ...

        discOsbParent.post(() -> {
          // Post in the parent's message queue to make sure the parent
          // lays out its children before we call getHitRect()
          Rect delegateArea = new Rect();
          discOsb.getHitRect(delegateArea);
          delegateArea.right += getResources().getDimensionPixelSize(R.dimen.disc_in_osb_extra_touch_area);
          TouchDelegate expandedArea = new TouchDelegate(delegateArea, discOsb);
          // give the delegate to an ancestor of the view we're delegating the area to
...
        });
      }

我看到只有一个选项可以更改touchArea right，而不能更改end。

有什么方法可以将触摸区域扩展到end吗？
