关于Fragment嵌套Fragment并且使用tablayout的错误

今天碰到了这样一个问题,找了很多资料都没解决,记录一下,留给有缘人,希望你们不用花这么多时间

是这样的解决的:我尝试了在activity中使用tablayout+viewpager 并且使用FragmentStatePagerAdapter作为适配器,是没有问题的,但是嵌套Fragment就出现了问题,后来发现是上下文用错了,应该是嵌套的Fragment就不能使用全局的上下文,改成activity的上下文就可以了

同时注意嵌套Fragment拿到FragmentManager要用这个方法
getChildFragmentManager()

错误:

下面是Activity

package com.example.oschina.ui.activity;import android.os.Bundle;import android.support.v4.app.FragmentManager;import android.support.v7.app.AppCompatActivity;import com.example.oschina.R;import com.example.oschina.ui.fragment.homefragment.MoveStirFragment;public class YhdActivity extends AppCompatActivity {/*    @Bind(R.id.stirfragment_tl)    TabLayout mStirfragmentTl;    @Bind(R.id.stirfragment_vp)    ViewPager mStirfragmentVp;    private List<MoveStirFragmentInfo> mShowItems = new ArrayList<>();*/    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_yhd);        /*ButterKnife.bind(this);*//*        //通过Stringarray数组去获取字符串        String[] titles = Utils.getStringArray(R.array.tab_names);        mShowItems.add(new MoveStirFragmentInfo(titles[0], new NewStirFragment()));        mShowItems.add(new MoveStirFragmentInfo(titles[1], new HotStirFragment()));        mShowItems.add(new MoveStirFragmentInfo(titles[2], new MyStirFragment()));        MoveStirPagerAdapter adapter = new MoveStirPagerAdapter(getSupportFragmentManager(), mShowItems);        mStirfragmentVp.setAdapter(adapter);        mStirfragmentTl.setupWithViewPager(mStirfragmentVp);*/        FragmentManager supportFragmentManager = getSupportFragmentManager();        supportFragmentManager.beginTransaction().add(R.id.main_fragment,new MoveStirFragment()).commit();    }}

下面是外层的Fragment

package com.example.oschina.ui.fragment.homefragment;import android.content.res.ColorStateList;import android.graphics.Color;import android.os.Bundle;import android.support.design.widget.TabLayout;import android.support.v4.app.Fragment;import android.support.v4.view.ViewPager;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import com.example.oschina.OSChinaApplication;import com.example.oschina.R;import com.example.oschina.adapter.MoveStirPagerAdapter;import com.example.oschina.bean.MoveStirFragmentInfo;import com.example.oschina.ui.fragment.strifragment.HotStirFragment;import com.example.oschina.ui.fragment.strifragment.MyStirFragment;import com.example.oschina.ui.fragment.strifragment.NewStirFragment;import com.example.oschina.utils.Utils;import java.util.ArrayList;import java.util.List;/** * 动弹Fragment * Created by Sang on 2016-12-04. */public class MoveStirFragment extends Fragment {    private TabLayout mStirfragmentTl;    private ViewPager mStirfragmentVp;    private List<MoveStirFragmentInfo> mShowItems = new ArrayList<>();    @Override    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {        View successView = View.inflate(**OSChinaApplication.mContext**, R.layout.fragment_movestir, null);        mStirfragmentTl = (TabLayout) successView.findViewById(R.id.stirfragment_tl);        mStirfragmentVp = (ViewPager) successView.findViewById(R.id.stirfragment_vp);        initView();        return successView;    }    private void initView() {        String[] titles = Utils.getStringArray(R.array.tab_names);        mShowItems.add(new MoveStirFragmentInfo(titles[0], new NewStirFragment()));        mShowItems.add(new MoveStirFragmentInfo(titles[1], new HotStirFragment()));        mShowItems.add(new MoveStirFragmentInfo(titles[2], new MyStirFragment()));        MoveStirPagerAdapter adapter = new MoveStirPagerAdapter(getChildFragmentManager(), mShowItems);        mStirfragmentVp.setAdapter(adapter);        mStirfragmentTl.setupWithViewPager(mStirfragmentVp);        mStirfragmentTl.setTabTextColors(ColorStateList.valueOf(Color.BLACK));    }}

只要将上面加粗的全局上下文改成getContext()就好了
