無法啓動活動ComponentInfo {Activity}：android.view.InflateException：二進制XML文件行錯誤膨脹類片段

當我嘗試在活動中啓動片段時，出現以下異常。看起來這是一個常見問題，我擁有答案中建議的所有必要權限。痕跡不是很有幫助。無法啓動活動ComponentInfo {Activity}：android.view.InflateException：二進制XML文件行錯誤膨脹類片段

而且，此Activity類中的setContentView(R.layout.activity_view_record);發生異常。我試圖儘可能簡化應用程序，但它獲得相同的例外

public class ViewRecordActivity extends AppCompatActivity { 

    private static String RECORD_ID = "RECORD_ID"; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_view_record); 

     /*Bundle extras = getIntent().getExtras(); 
     Integer recordId = extras.getInt(RECORD_ID);*/ 

     ViewRecordFragment viewRecordFragment = ViewRecordFragment.newInstance(1); 
     //viewRecordFragment.setArguments(getIntent().getExtras()); 

     FragmentManager fragmentManager = getSupportFragmentManager(); 
     fragmentManager 
       .beginTransaction() 
       .replace(R.id.view_record_fragment, viewRecordFragment 
       ).commit(); 
    } 


    public static class ViewRecordFragment extends Fragment { 

     private static String RECORD_ID = "RECORD_ID"; 

     public ViewRecordFragment() { 
     } 

     @Override 
     public View onCreateView(LayoutInflater inflater, ViewGroup container, 
           Bundle savedInstanceState) { 
      /*gridview = (GridView) getActivity().findViewById(R.id.image_grid_view);*/ 

      //Integer recordId = getArguments().getInt(RECORD_ID); 
      //loadImageResourcesAsync(recordId); 

      return inflater.inflate(R.layout.fragment_view_record, container, false); 
     } 

     public static ViewRecordFragment newInstance(Integer recordId) { 
      ViewRecordFragment fragment = new ViewRecordFragment(); 
      //fragment.loadImageResourcesAsync(recordId); 
      /*Bundle bundle = new Bundle(); 
      bundle.putInt(RECORD_ID, recordId); 
      fragment.setArguments(bundle);*/ 
      return fragment; 
     } 

     private void loadImageResourcesAsync(Integer recordId) { 
      new LoadImageResourcesAsync(getActivity()).execute(recordId); 
     } 

    } 
}

活動的佈局如下。

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent"> 

     <fragment 
      android:id="@+id/view_record_fragment" 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" /> 


     <!--<fragment xmlns:android="http://schemas.android.com/apk/res/android" 
      xmlns:tools="http://schemas.android.com/tools" 
      android:id="@+id/view_record_fragment" 
android:name="com.xxx.xxx.view.ViewRecordActivity$ViewRecordFragment" 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" 
      tools:layout="@layout/fragment_view_record" />--> 


    </LinearLayout>

任何幫助，非常感謝。

在你的xml佈局中有一些問題。檢查你的xml的第5行 – Passiondroid

@Passiondroid我添加了xml文件。我沒有看到第5行的問題 –

第5行有片段 –

在佈局中添加碎片的基本方法如下所示。你必須提及片段的類名。

<fragment android:name="com.example.android.fragments.HeadlinesFragment" 
      android:id="@+id/headlines_fragment" 
      android:layout_weight="1" 
      android:layout_width="0dp" 
      android:layout_height="match_parent" />

我已經這樣做了，這是一樣的例外。請檢查新的編輯。謝謝:) –

嘿謝謝它的工作，現在我可以從這裏建立，非常感謝 –
