fragment中禁用后退键

Question

在fragment类中禁用后退键。

代码如下：

public class Login extends Fragment {
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
       ,Bundle savedInstanceState) {
          ViewGroup root = (ViewGroup) inflater.inflate(R.layout.login, null);
          return root;
          }
          public void onBackPressed() {
     }
}

Answer 1

应该只能在宿主activity中控制，你fragment和宿主通信去控制后退键
