当我从 Main Activity 调用片段函数时，片段 onCreateView 再次调用？

Question

实际上我的问题是我想在按钮 clickListner 上将字符串从主活动发送到我的片段，但是当我从主活动调用片段函数时，片段的 onCreateView 再次调用并且一切都再次初始化。请指导我如何避免这个问题谢谢。

这是我的 MainActivity 代码：

ThirdFragment thirdFragment=new ThirdFragment();
                            FragmentTransaction fragmentTransaction=getSupportFragmentManager().beginTransaction().add(R.id.thirdfragment,thirdFragment,null);
                           fragmentTransaction.commitNow();
                            ThirdFragment fragment = (ThirdFragment) getSupportFragmentManager().findFragmentById(R.id.thirdfragment);
                           if(fragment!=null) {
                               fragment.Subcategories(text);

                           } 

这里是片段函数代码：

public void Subcategories(String text){

    Log.d(TAG, "Subcategories: fragment calling "+text);

        mAPIService.searchcategory("2",text).enqueue(new Callback<ArrayList<DataStored>>() {
            @Override
            public void onResponse(Call<ArrayList<DataStored>> call, Response<ArrayList<DataStored>> response) {
               myRecyclerAdapter.addItems(response.body());
            }
            @Override
            public void onFailure(Call<ArrayList<DataStored>> call, Throwable t) {
                myRecyclerAdapter.addItems(null);


            }
        });


}

试试这样；`

 ThirdFragment thirdFragment=new ThirdFragment();
    FragmentTransaction fragmentTransaction=getSupportFragmentManager().beginTransaction().replace(R.id.thirdfragment,thirdFragment,null);
                               fragmentTransaction.commitNow();
                                ThirdFragment fragment = (ThirdFragment) getSupportFragmentManager().findFragmentById(R.id.thirdfragment);
                               if(fragment!=null) {
                                   fragment.Subcategories(text);

                               } `
