無法從佈局獲得資源訪問XML文件中未發現異常和XML文件是在res文件夾

Question

這是從哪兒我訪問search_product_item.xml我的代碼

@Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     if (RootUtil.isDeviceRooted()) 
      finish(); 
     if (getResources().getBoolean(R.bool.portrait)) { 
      SPAN_COUNT = 2; 
      setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); 
     } else { 
      SPAN_COUNT = 4; 
      setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); 

     } 

     setContentView(R.layout.search_product_item); 

這是search_product_item XML文件

<?xml version="1.0" encoding="UTF-8"?> 


<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:background="@drawable/background" 
    android:orientation="vertical" > 

    <include 
     android:id="@+id/toolbar" 
     layout="@layout/toolbar_main" /> 

    <include 
     android:id="@+id/footerLinkView" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_alignParentBottom="true" 
     layout="@layout/layout_footer_link_view" /> 

    <include 
     android:id="@+id/footerView" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_above="@+id/footerLinkView" 
     layout="@layout/layout_footer" /> 


    <android.support.v7.widget.RecyclerView 
     android:id="@+id/recyclerView" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:layout_above="@+id/footerView" 
     android:layout_below="@+id/toolbar" 
     android:layout_centerInParent="true" /> 

</RelativeLayout> 

我logcat的

我打掃我的項目100倍，重啓eclipse但問題沒有解決。請提供解決方案。

Answer 1

您的.xml文件是否在res文件夾中？

如果是將其放在RES /佈局/ file.xml

Answer 2

try this 
    @Override 
     protected void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
      setContentView(R.layout.search_product_item); 
      if (RootUtil.isDeviceRooted()) 
       finish(); 
      // Log.d(TAG, "onCreate()"); 

      if (getResources().getBoolean(R.bool.portrait)) { 
       SPAN_COUNT = 2; 
       setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); 
      } else { 
       SPAN_COUNT = 4; 
       setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); 

      } 

Answer 3

替換此：

​​

通過這樣的：

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

     if (RootUtil.isDeviceRooted()) 
      finish(); 
     // Log.d(TAG, "onCreate()"); 

     if (getResources().getBoolean(R.bool.portrait)) { 
      SPAN_COUNT = 2; 
      setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); 
     } else { 
      SPAN_COUNT = 4; 
     setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); 

     } 

其實ü服用佈局之外的onCreate 。謝謝
