android fragment中getActivity方法报错

Question

我想在fragment中获取activity对象，但是无法使用getActivity方法。

activity中创建fragment对象

    public void initFragment() {
        // TODO Auto-generated method stub

         FragmentManager fManager=getSupportFragmentManager();

        FragmentTransaction transaction=fManager.beginTransaction();

        transaction.replace(R.id.fl_content,new ContentFragment(), FRAGMENT_CONTENT);  //是否为构造时要求的假的fragment容器??new对象的时候才是真正显示的布局
        transaction.replace(R.id.fl_left_menu,new LeftMenuFragment(), FRAGMENT_LEFT_MENU);

        transaction.commit();

        fManager.findFragmentByTag(FRAGMENT_LEFT_MENU);

    }

我想在fragment基类中获取activity就是不行，请问应该怎么办？

Answer 1

getActivity()Wrong writing, there is an extra "u"

Answer 2

I didn’t see where you used getActivity(). Your problem is not the same as your screenshot.

Answer 3

getactivity is spelled wrong

Answer 4

Even if you spell it correctly, there will be a NullPointerException problem when calling getActivity in the onCreate method. At this time, the fragment has not been attached. It is recommended that the subject take a look at the fragment life cycle

Answer 5
