我想注册点击包裹在ClickableSpan文本，只有当他们被点击超过说1秒。有没有办法做到这一点？如果不是，捕捉双击也将被罚款。

I would like to register clicks on a text wrapped in a ClickableSpan only if they are clicked for over say 1 second. Is there any way to do this? If not, capturing a double click would also be fine.

这将是巨大的，如果onClick的方法捕捉到了有关点击的一些元数据的事件 - 那么我可以说，如果忽略点击长度短

It would be great if the onClick method captured an event that had some meta data about the click - then I could say ignore if the click length was short.

任何意见？

谢谢，维克多

LongClickableSpan在同一个地方：

LongClickableSpan in the same place:

    package leeon.mobile.BBSBrowser;

    import android.text.style.ClickableSpan;
    import android.view.View;

    public abstract class LongClickableSpan extends ClickableSpan {

      abstract public void onLongClick(View view);

    }
