1.  判断一个String是否为空时候，string.length > 1 比string != "" 好用～原因不知～～反正用length解决了～

2, android:fillViewport="true" on theScrollView.  scrollview  必须要设置这个为true,才能扩展内部的部件显示出来

3,  点击textview，展开更多内容的方法。

Actually, the way android platform does that is by setting the MaxLine to Integer.MAX_VALUE. textView.setMaxLines(Integer.MAX_VALUE); also, if you are using Ellipsize, don't forget to set to null. textView.setEllipsize(null); just check how the android framework do just that ;) watch the setMaxLines(Integer.MAX_VALUE); private void applySingleLine(boolean singleLine, boolean applyTransformation) {     mSingleLine = singleLine;     if (singleLine) {         setLines(1);         setHorizontallyScrolling(true);         if (applyTransformation) {             setTransformationMethod(SingleLineTransformationMethod.getInstance());         }        } else {             setMaxLines(Integer.MAX_VALUE);             setHorizontallyScrolling(false);             if (applyTransformation) {                  setTransformationMethod(null);         }        }      }

4， 

setEllipsize

这个是内容过长加省略号的作用～
