如何检查片段视图是出现在当前窗口中还是不在当前窗口中？

Question

我内部有一个滚动视图和一个文本视图，我想知道它是不在窗口内还是还在窗口内。

scrollView.setOnScrollChangeListener(new View.OnScrollChangeListener() {
                @Override
                public void onScrollChange(View v, int scrollX, int scrollY, int oldScrollX, int oldScrollY) {
                    L.e(" isShown " + textView.isShown());
                }
            });

谢谢。

使用以下代码。对我来说很完美

namespace RenderAPI
{
   // Put all rendering related functions here
}

namespace PersistenceAPI
{
   // Put all read from disk and write to disk functions here.
}

namespace MySuperCoolBusinessLogicAPI
{
   // Put all the functions dealing with your super cool business logic here.
}
