Android.view.inflateexception：二进制XML文件第7行：二进制XML文件第7行：inflating类片段时出错

Question

我刚刚实现了我的第四个选项卡到我的应用程序中，已经实现了谷歌地图。在此实现之前，我的应用程序运行良好，但现在当我更改选项卡时，它会崩溃。我在这里看到过类似的问题，但没有一个有答案（实际上有这么多不同的原因和回应这个问题）

下面是fragmentshouts_maps类

package com.example.hp_user.shoutfinal28;



import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;


public class FragmentShouts_Maps extends Fragment implements OnMapReadyCallback {


public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Get the view from fragment shouts.xml
    View root_view = inflater.inflate(R.layout.fragmentshouts_maps, container, false);
    SupportMapFragment supportMapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.Maps1);
    if (supportMapFragment!= null) {
        supportMapFragment.getMapAsync(this);
    }
    return root_view;
}


@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
}

@Override
public void onMapReady (GoogleMap map) {
    map.addMarker(new MarkerOptions()
            .position(new LatLng(0, 0))
            .title("Marker"));
}

}

查看寻呼机适配器类

package com.example.hp_user.shoutfinal28;


import android.content.Context;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentStatePagerAdapter;



public class ViewPagerAdapter extends FragmentStatePagerAdapter {

final int PAGE_COUNT = 4;
// Tab Titles
private String tabtitles[] = new String[] {"Home","Shouts","Maps","Shouters"};
Context context;

public ViewPagerAdapter(FragmentManager fm) {
    super(fm);
}

@Override
public int getCount() {
    return PAGE_COUNT;
}


public Fragment getItem(int position) {
    switch (position) {

        // Open Fragment home.java
        case 0:
            FragmentHome fragmenthome = new FragmentHome();
            return fragmenthome;

        // Open Fragment shouters.java
        case 1:
            FragmentShouts fragmentshouts = new FragmentShouts();
            return fragmentshouts;

        case 2:
            FragmentShouts_Maps fragmentshouts_maps = new FragmentShouts_Maps();
            return fragmentshouts_maps;

        case 3:
            FragmentShouters fragmentshouters = new FragmentShouters();
            return fragmentshouters;



    }
    return null;
}

@Override
public CharSequence getPageTitle(int position) {
    return tabtitles[position];
}


}

这是我的错误日志

尝试在OnActivityCreated()中执行相同的操作

   public void onActivityCreated(Bundle savedInstanceState) {
                    super.onActivityCreated(savedInstanceState);
                    SupportMapFragment supportMapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.Maps1);
                    if (supportMapFragment!= null) {
                        supportMapFragment.getMapAsync(this);
                    }
                }
