Fragment中的onCreatView()没有立即调用

项目中发现Fragment中的onCreatView()没有立即调用，例如：

@Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();

fragmentTransaction.add(R.id.fragment, new MyFragment());
fragmentTransaction.commit();

fuc(); // 在fragment的onCreatView()前调用
}

解决办法：

在onStart()中创建fragment，并调用executePendingTransactions()方法立即执行。

@Override
protected void onStart(){
super.onStart();

FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();

fragmentTransaction.add(R.id.fragment, new MyFragment());
fragmentTransaction.commit();
fragmentManager.executePendingTransactions();

fuc();  // 在fragment的onCreatView()后调用
}
