如何得到fragment的高度？
业精于勤，荒于嬉;行成于思，毁于随。
Fragment is attached to the View container. Isn’t the height of the View the same as the height of the Fragment?
fragment没有提供像Activity类似的onWindowFocusChanged方法，但可以使用ViewTreeObserver Come and get it.
fragment
Activity
onWindowFocusChanged
ViewTreeObserver
transaction.replace(frameLayout, fragment)Just get the height of frameLayout
fragment.getView().getMeasuredHeight()
