1 Layout l = textview.getLayout();
2         if ( l != null){
3             int lines = l.getLineCount();
4             if ( lines > 0)
5                 if ( l.getEllipsisCount(lines-1) > 0)
6                     Log.d(TAG, "Text is ellipsized");
7         }   

textview有个特性,是当改变文字的时候getlayout为null,需要做一定的延时再获取

而且获取后不能在子线程中更新ui,会报错
