Question

Fragment的onCreate和onCreateView的区别

Answer 1

onCreate是指创建该fragment类似于Activity.onCreate，你可以在其中初始化除了view之外的东西，onCreateView是创建该fragment对应的视图，你必须在这里创建自己的视图并返回给调用者，例如
return inflater.inflate(R.layout.fragment_settings, container, false);。
super.onCreateView有没有调用都无所谓，因为super.onCreateView是直接返回null的。

Answer 2

1）onCreate是指创建该fragment，类似于Activity.onCreate，可以在其中初始化除了view之外的东西；
2）onCreateView是创建该fragment对应的视图，必须在这里创建自己的视图并返回给调用者。
例如
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.main,container,false);
mLine1 = (TextView)rootView.findViewById(R.id.line1);
mLine2 = (TextView)rootView.findViewById(R.id.line2);
mDescription1 = (TextView)rootView.findViewById(R.id.line1_description);
mDescription2 = (TextView)rootView.findViewById(R.id.line2_description);
mVersion = (TextView)rootView.findViewById(R.id.version);
mSignWifi = (TextView)rootView.findViewById(R.id.advice);
mSignStreaming = (LinearLayout)rootView.findViewById(R.id.streaming);
mSignInformation = (LinearLayout)rootView.findViewById(R.id.information);
mPulseAnimation = AnimationUtils.loadAnimation(mApplication.getApplicationContext(), R.anim.pulse);
mTextBitrate = (TextView)rootView.findViewById(R.id.bitrate);
return rootView ;
}
