Question

我想导航到活动中的片段。在导航抽屉中使用两个片段FragmentA和FragmentB。请在下面找到代码：

FragmentA.java

public class FragmentA extends Fragment{

Button btnContinue;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.fragA, container, false);
    btnRegister=(Button)rootView.findViewById(R.id.btn_register);
    btnRegister.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View arg0) {
        // TODO Auto-generated method stub

        Intent i =new Intent(getActivity(),Register.class);
        startActivity(i);

       }
     });

    return rootView;
  }
}

Register.java是另一项活动，我点击了保存详情按钮。

btnSave.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View arg0) {
        // TODO Auto-generated method stub

        new Save_register_detail_task(Register.this,newfirstname, newlastname, newemail, newpassword).execute();

       }
     });

Save_register_detail_task.java（AsyncTask）。在其onPostExecute中，我有以下代码： R.id.frame_container在导航抽屉的布局中定义。

Fragment fragment = new FragmentB();
            fragment.setArguments(bundle);  
            //activity.finish();
            FragmentManager fragmentManager = ((FragmentActivity)activity).getSupportFragmentManager();

            FragmentTransaction fragmentTransaction = fragmentManager
                    .beginTransaction();
            fragmentTransaction.replace(R.id.frame_container,
                    fragment, "fragb")
                    .addToBackStack("register")
                    .commit();

我应该用什么代替R.id.frame_container？或者是否有任何其他方式来声明片段管理器？

从另一个活动替换片段。 java.lang.IllegalArgumentException：找不到id的视图
