谷歌地圖V2例外：在分段錯誤充氣類片段

問候研究員＃1社區，谷歌地圖V2例外：在分段錯誤充氣類片段

我正在開發Android應用程序，在片段和ViewPager顯示谷歌地圖V2。而我面臨的一個問題是關於擴展包含Google Maps V2的片段佈局。我正在搜索並尋找此鏈接Android, google maps fragment and viewpager - Error inflating class fragment獲取答案，因爲該方法與我一直在尋找的方法相同，在片段中誇大Google Maps V2，但仍然無效。我也在這個鏈接Android Google Maps in Fragment也在搜索，但結果是一樣的。

這是我fragment_layout.xml：

<?xml version="1.0" encoding="utf-8"?> 
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:fillViewport="true" 
    > 
    <LinearLayout 
     android:id="@+id/layout_detail_fragment_secondlist" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:orientation="vertical" 
     android:background="#ffffff" 
     > 
     <ImageView 
      android:id="@+id/detail_item_imv_secondlist" 
      android:layout_width="match_parent" 
      android:layout_height="150dp" 
      android:contentDescription="@null" 
      android:scaleType="fitCenter" 
      android:adjustViewBounds="true" 
      /> 
     <TextView 
      android:id="@+id/detail_item_tv_title_secondlist"

      android:layout_height="30dp" 
      android:background="#cae0e0e0" 
      android:gravity="left|center_vertical" 
      android:textSize="15sp" 
      android:textStyle="bold" 
      /> 
     <TextView 
      android:id="@+id/detail_item_tv_content_secondlist" 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      android:gravity="fill" 
      android:padding="10dp" 
      android:textSize="12sp" 
      android:lineSpacingMultiplier="1.5" 
      /> 
     <fragment 
      android:id="@+id/detail_item_map_content_secondlist" 
      android:layout_width="match_parent" 
      android:layout_height="150dp" 
      class="com.google.android.gms.maps.SupportMapFragment" 
      /> 
    </LinearLayout> 
</ScrollView>

這是我fragment_class：

package com.gbu.app.template.fragments; 

import java.util.ArrayList; 

import com.gbu.app.template.DetailSecondListActivity; 
import com.gbu.app.template.R; 
import com.gbu.app.template.data.StoreObject; 

import android.os.Bundle; 
import android.support.v4.app.Fragment; 
import android.util.DisplayMetrics; 
import android.util.Log; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.ImageView; 
import android.widget.LinearLayout; 
import android.widget.TextView; 

public class DetailSecondListViewPagerFragment extends Fragment { 
    private ImageView detail_item_imv_secondlist; 
    private LinearLayout layout_detail_fragment_secondlist; 
    private TextView detail_item_tv_title_secondlist, detail_item_tv_content_secondlist; 
    private DisplayMetrics detail_metrics_secondlist; 
    private ArrayList<StoreObject> detail_store; 

    @Override 
    public View onCreateView(LayoutInflater inflator, ViewGroup container, Bundle savedInstanceState) { 
     super.onCreateView(inflator, container, savedInstanceState); 
     View view_detail_secondlist = inflator.inflate(R.layout.item_viewpager_detail_secondlist, container, false); 
     savedInstanceState = getArguments(); 
     detail_metrics_secondlist = new DisplayMetrics(); 
     getActivity().getWindowManager().getDefaultDisplay().getMetrics(detail_metrics_secondlist); 
     layout_detail_fragment_secondlist = (LinearLayout) view_detail_secondlist.findViewById(R.id.layout_detail_fragment_secondlist); 
     detail_item_imv_secondlist = (ImageView) layout_detail_fragment_secondlist.findViewById(R.id.detail_item_imv_secondlist); 
     detail_item_tv_title_secondlist = (TextView) layout_detail_fragment_secondlist.findViewById(R.id.detail_item_tv_title_secondlist); 
     detail_item_tv_content_secondlist = (TextView) layout_detail_fragment_secondlist.findViewById(R.id.detail_item_tv_content_secondlist); 
     detail_store = new ArrayList<StoreObject>(); 
     detail_store = DetailSecondListActivity.detail_store; 
     startApp(savedInstanceState); 
     return view_detail_secondlist; 
    } 

    private void startApp(Bundle savedInstanceState) { 
     // TODO Auto-generated method stub 
     detail_item_imv_secondlist.getLayoutParams().height = (int) (detail_metrics_secondlist.heightPixels * 0.38); 
     detail_item_imv_secondlist.setImageResource(R.drawable.default_images); 
     detail_item_tv_title_secondlist.setText(detail_store.get(savedInstanceState.getInt("current_item")).getTitle()); 
     detail_item_tv_content_secondlist.setText(detail_store.get(savedInstanceState.getInt("current_item")).getAddress()); 
    } 

    public void onDestroyView() { 
     super.onDestroyView(); 
     Log.d("message", "onDestroyView"); 
    } 
}

這是pager_adapter：

package com.gbu.app.template.adapters; 

import com.gbu.app.template.DetailSecondListActivity; 
import com.gbu.app.template.fragments.DetailSecondListViewPagerFragment; 

import android.os.Bundle; 
import android.support.v4.app.Fragment; 
import android.support.v4.app.FragmentManager; 
import android.support.v4.app.FragmentPagerAdapter; 

public class DetailSecondListPagerAdapter extends FragmentPagerAdapter { 
    DetailSecondListViewPagerFragment dslvpf; 
    Bundle args; 

    public DetailSecondListPagerAdapter(FragmentManager fm) { 
     super(fm); 
     // TODO Auto-generated constructor stub 
    } 

    @Override 
    public Fragment getItem(int arg0) { 
     // TODO Auto-generated method stub 
     dslvpf = new DetailSecondListViewPagerFragment(); 
     args = new Bundle(); 
     args.putInt("current_item", arg0); 
     dslvpf.setArguments(args); 
     return dslvpf; 
    } 

    @Override 
    public int getCount() { 
     // TODO Auto-generated method stub 
     return DetailSecondListActivity.detail_store.size(); 
    } 

}

這是佈局Main_Activity。 xml：

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    > 
    <android.support.v4.view.ViewPager 
     android:id="@+id/detail_view_pager_second_list" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:layout_alignParentTop="true" 
     /> 
</RelativeLayout>

這是我Main_Activity的代碼：

package com.gbu.app.template; 

import java.util.ArrayList; 

import com.gbu.app.template.adapters.DetailSecondListPagerAdapter; 
import com.gbu.app.template.data.StoreObject; 

import android.content.Intent; 
import android.os.Bundle; 
import android.support.v4.app.FragmentActivity; 
import android.support.v4.view.ViewPager; 

public class DetailSecondListActivity extends FragmentActivity { 
    private Intent i; 
    public static ArrayList<StoreObject> detail_store; 
    private ViewPager detail_viewpager_secondlist; 
    private DetailSecondListPagerAdapter detail_secondlist_pager_adapter; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_detail_secondlist); 
     detail_viewpager_secondlist = (ViewPager) findViewById(R.id.detail_view_pager_second_list); 
     detail_store = new ArrayList<StoreObject>(); 
     detail_store = SecondListActivity.item_store; 
    } 

    @Override 
    protected void onStart() { 
     super.onStart(); 
     detail_secondlist_pager_adapter = new DetailSecondListPagerAdapter(getSupportFragmentManager()); 
     detail_viewpager_secondlist.setAdapter(detail_secondlist_pager_adapter); 
    } 

    @Override 
    protected void onStop() { 
     super.onStop(); 
     TabGroupActivity parentActivity = (TabGroupActivity) getParent(); 
     parentActivity.onActivityResult(3, RESULT_OK, i); 
    } 

    @Override 
    protected void onDestroy() { 
     super.onDestroy(); 
    } 

    @Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     super.onActivityResult(requestCode, resultCode, data); 
     if (requestCode == 4 && resultCode == RESULT_OK) { 
      i = data; 
      startApp(data); 
     } 
    } 

    private void startApp(Intent data) { 
     // TODO Auto-generated method stub 
     detail_viewpager_secondlist.setCurrentItem(data.getIntExtra("position", 0)); 
    } 
}

這是AndroidManifest.xml中：

</manifest>

我的問題是，如果我將谷歌地圖V2在Main_Activity，地圖工作得很好，顯示正常。但是，如果我放置片段，結果將觸發異常：錯誤膨脹類片段。這是一個顯示異常的logcat的，我不知道是什麼原因引起的，因爲它沒有顯示類似的ClassNotFoundException或NullException或某事的原因是導致它：

它只是從我的代碼說我fragment_class中，錯誤指向只在充氣佈局在：

View view_detail_secondlist = inflator.inflate(R.layout.item_viewpager_detail_secondlist, container, false);

所以，我在這裏失蹤了什麼？這是我沒有添加的一些代碼？或者，我可能沒有真正理解開發片段的概念，Google Maps V2？任何幫助將會是重要的，謝謝。

您還沒有顯示地圖初始化這個它MapFragment。請給我看。 – Kishan

謝謝你的回覆..即使我沒有初始化它，通常它會顯示地圖..我以前在我的Main_Activity嘗試過，並正常工作，即使我沒有初始化它.. –
