调用子片段时未找到id的视图

Question

package info.androidhive.slidingmenu;

import java.lang.reflect.Field;

import android.app.Fragment;
import android.app.FragmentManager;
import android.app.FragmentTransaction;
import android.os.Bundle;
import android.support.v4.view.ViewPager;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.ImageButton;

public class HomeFragment extends Fragment {

 public static HomeFragment newInstance() 
 {
        return new HomeFragment();
    }

public HomeFragment(){}

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


    View rootView = inflater.inflate(R.layout.fragment_home, container, false);

    ImageButton ib = (ImageButton) rootView.findViewById(R.id.buttonEnq);
    ib.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            InfoFragment infoFragment = new InfoFragment();
            /*FragmentManager fm = getFragmentManager();
            fm.beginTransaction().replace(R.id.frame_container, infoFragment).commit();
            */

            FragmentTransaction ft = getChildFragmentManager().beginTransaction();
            ft.setCustomAnimations(R.anim.abc_slide_out_bottom, 0);
            ft.replace(R.id.frame_container,infoFragment);
            ft.commit();
        }
    });

    ViewPager viewPager = (ViewPager)rootView.findViewById(R.id.myfivepanelpager);
    ImageAdapter adapter1 = new ImageAdapter(this.getActivity());
    viewPager.setAdapter(adapter1);

    return rootView;

    }

@Override
public void onDetach(){
    super.onDetach();

    try{

        Field childFragmentManager = Fragment.class.getDeclaredField("mChildFragmentManager");
        childFragmentManager.setAccessible(true);
        childFragmentManager.set(this,null);

    }catch(NoSuchFieldException e){
        throw new RuntimeException(e);
    }catch (IllegalAccessException e) {
        throw new RuntimeException(e);
    }
  } 
}

• Android片段找不到ID的视图？
• 找不到id 0x7F090005的视图
• 找不到片段id的视图

你能告诉我我做错了什么吗？

Answer 1

FragmentTransaction ft = getChildFragmentManager().beginTransaction();

FragmentTransaction ft = getActivity().getFragmentManager().beginTransaction();
