在使用ListFragment的setEmptyText時報java.lang.IllegalStateExceptio

今天搞了好久, 才基本解決了這個問題. 

                         <!--這樣命名我就不多說了-->                    <!-- 為什麼這樣命名,且看下文 -->             

 1            (mList !=                        View root =          (root ==                IllegalStateException("Content view not yet created"           (root              mList =         }              mStandardEmptyView =              (mStandardEmptyView ==                               }                mProgressContainer =             mListContainer =             View rawListView =              (!(rawListView                   (rawListView ==                                                    "Your content must have a ListView whose id attribute is " +                             "'android.R.id.list'"                                            "Content has view with id attribute 'android.R.id.list' "                         + "that is not a ListView class"              mList =              (mEmptyView !=               }   (mEmptyText !=              mListShown =            (mAdapter !=              ListAdapter adapter =             mAdapter =           }                                         (mProgressContainer !=                  setListShown(,         }

在程式中

 ((TextView)getListView().getEmptyView()).setText(getString(R.string.list_no_data));

這樣就成功了.

為什麼不直接用setEmptyText(CharSequence text) 反正試了很久都沒有成功.一直不知道

   INTERNAL_EMPTY_ID = 0x00ff0001;

代表的什麼,各種試都沒有成功, google,度娘了很久,唉.....
