从主要活动中调用片段方法

Question

Hi I am calling fragment method from activity with this code

ConversationFragment frgObj;
frgObj.addMessageToList("asd", this);

But addMessageToList method is calling before oncreateview in fragment.I am defining some variables in oncreateview for use in addMessageToList method.So that my app is crashing because I can't use important variables in addMessageToList method because it's not defined.

How can I fix it ? I have to run oncreateview then run addMessageToList.

Answer 1

First do fragmentTransaction of ConversationFragment that means after committing your fragmentTransaction, call
getFragmentManager().executePendingTransactions(); and next call your
frgObj.addMessageToList("asd", this);
