Fragment嵌套使用的一些问题

因为项目需要在Fragment里面嵌套Fragment，只有第一次进去的时候能看嵌套的Fragment，在切换FragmentActivity 就看不见嵌套的了。

第一次TAB切换的时可以看见viewpager

--------------------编程问答--------------------

第二次就看不见了 --------------------编程问答-------------------- 下面是代码
第一个Fragment代码



package com.EIS.Fragments;



import java.util.ArrayList;

import java.util.List;



import com.EIS.R;

import com.EIS.Adapter.QueryFragmentPagerAdapter;

import com.EIS.Adapter.TabFragmentPagerAdapter;

import com.EIS.Listener.MenuButtonOnClickListener;



import android.app.Activity;

import android.os.Bundle;

import android.support.v4.app.Fragment;

import android.support.v4.view.ViewPager;

import android.support.v4.view.ViewPager.OnPageChangeListener;

import android.util.Log;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

import android.widget.RadioButton;

import android.widget.RadioGroup;

import android.widget.RadioGroup.OnCheckedChangeListener;



public class InterActionFragment extends Fragment {

        private View view;

        private ViewPager mViewPager;

        private TabFragmentPagerAdapter fragmentPagerAdapter;

        private RadioGroup group;

        private static List<Fragment> fragments;



        @Override

        public void onCreate(Bundle savedInstanceState) {

                super.onCreate(savedInstanceState);

        }



        @Override

        public View onCreateView(LayoutInflater inflater, ViewGroup container,

                        Bundle savedInstanceState) {

                view = inflater.inflate(R.layout.interactionview, container, false);

                mViewPager = (ViewPager) view.findViewById(R.id.query_viewpager);

                group = (RadioGroup) view.findViewById(R.id.group);

                fragments = new ArrayList<Fragment>();

                fragments.add(new EnterpriseQueryframgent());

                fragments.add(new EnterpriseQueryframgent());

                mViewPager.setAdapter(fragmentPagerAdapter);

                fragmentPagerAdapter = new TabFragmentPagerAdapter(

                                getFragmentManager(), fragments);



                group.setOnCheckedChangeListener(new OnCheckedChangeListener() {

                        @Override

                        public void onCheckedChanged(RadioGroup group, int checkedId) {

                                if (checkedId == R.id.bt_query) {

                                        

                                        mViewPager.setCurrentItem(0);

                                } else {

                                        

                                        mViewPager.setCurrentItem(1);

                                }

                        }

                });



                return view;

        }



}

FragmentPagerAdapter代码



package com.EIS.Adapter;



import java.util.List;

import android.support.v4.app.Fragment;

import android.support.v4.app.FragmentManager;

import android.support.v4.app.FragmentPagerAdapter;

import android.util.Log;



public class TabFragmentPagerAdapter extends FragmentPagerAdapter {



        public static final String ARGUMENTS_NAME = "EXPERTQUERY";



        private List<Fragment> fragments;



        public TabFragmentPagerAdapter(FragmentManager fm) {

                super(fm);

                // TODO Auto-generated constructor stub

        }



        public TabFragmentPagerAdapter(FragmentManager fm, List<Fragment> fragments) {

                super(fm);

                Log.i("ss", "查看调构造器 listsize（）：" + fragments.size());

                this.fragments = fragments;

        }



        @Override

        public Fragment getItem(int arg0) {

                Log.i("ss", "查看调用 fragments: " + fragments.get(arg0));

                return fragments.get(arg0);



        }



        @Override

        public int getCount() {

                return fragments.size();

        }



}

嵌套 Fragment代码



package com.EIS.Fragments;



import com.EIS.R;

import com.EIS.Listener.MenuButtonOnClickListener;



import android.os.Bundle;

import android.support.v4.app.Fragment;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

import android.widget.TextView;



public class EnterpriseQueryframgent extends Fragment implements

                MenuButtonOnClickListener {

        

        @Override

        public View onCreateView(LayoutInflater inflater, ViewGroup container,

                        Bundle savedInstanceState) {

                

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

                //tv_tabName.setText(bundle.getString(MainActivity.ARGUMENTS_NAME, ""));

                

                return rootView;

        }

        

        @Override

        public void OnClick(View v) {

                // TODO Auto-generated method stub

                

        }



}

布局XML摆出来看看吧

这个和布局没有关系吧？我贴在下面 --------------------编程问答--------------------
