ResourceNotFoundException雖然有資源

-1

我試圖創建一個微調不顯示下拉不像「--select option--」顯示一個不可選擇的文本。我用SO post的第二個答案爲「--select option--」創建了一個自定義微調適配器和一個TextView的佈局文件。ResourceNotFoundException雖然有資源

我得到6912-6912/com.examp.three E/AndroidRuntime﹕ FATAL EXCEPTION: main android.content.res.Resources$NotFoundException: Resource ID #0x7f04004e這個異常，雖然我已經傳遞了構造函數的佈局文件。

我在做什麼錯？

我剛剛調試了該應用程序，並且getNothingSelectedLayout的值爲2130968654。我保持在return layoutInflater.inflate(nothingSelectedLayout, parent, false);的斷點。 getNothingSelectedLayout的值仍然相同。在這之後，當我按下F8鍵，它進入Choreographer.class崩潰

像@Kumar蘭詹在他回答的評論說之前，我檢查了R.java類資源ID將錯誤日誌說是不存在。但我在R.java文件中找到了分配給support_simple_spinner_dropdown_item的ID。我發現，在R.java文件

在這裏，在錯誤日誌中顯示Resource ID #0x7f04004e的代碼：

ArrayAdapter<String> adapterBankName = new ArrayAdapter 
      (CheckAmountActivity.this, android.R.layout.simple_spinner_dropdown_item, paymentMode) { 
     public View getDropDownView(int position, View convertView, ViewGroup parent) { 

      View v = super.getDropDownView(position, convertView, parent); 
      ((TextView) v).setGravity(Gravity.CENTER); 
      ((TextView) v).setTextColor(Color.BLACK); 

      return v; 

     } 
    }; 

    spinnerBankName.setAdapter(new NDSpinner(adapterBankName, R.layout.spinnertitle, getApplicationContext())); //the constructor of NDSpinner class

這是NDSpinner類：

public class NDSpinner implements SpinnerAdapter, ListAdapter { 

protected static final int EXTRA = 1; 
protected SpinnerAdapter adapter; 
protected Context context; 
protected int nothingSelectedLayout; 
protected int nothingSelectedDropdownLayout; 
protected LayoutInflater layoutInflater; 
String item; 


public NDSpinner(
     SpinnerAdapter spinnerAdapter, 
     int nothingSelectedLayout, Context context) { 

    this(spinnerAdapter, nothingSelectedLayout, -1, context); 
} 


public NDSpinner(SpinnerAdapter spinnerAdapter, 
       int nothingSelectedLayout, int nothingSelectedDropdownLayout, Context context) { 
    this.adapter = spinnerAdapter; 
    this.context = context; 
    this.nothingSelectedLayout = nothingSelectedLayout; 
    this.nothingSelectedDropdownLayout = nothingSelectedDropdownLayout; 
    layoutInflater = LayoutInflater.from(context); 
} 

@Override 
public final View getView(int position, View convertView, ViewGroup parent) { 
    // This provides the View for the Selected Item in the Spinner, not 
    // the dropdown (unless dropdownView is not set). 
    if (position == 0) { 
     return getNothingSelectedView(parent); 
    } 
    return adapter.getView(position - EXTRA, null, parent); // Could re-use 
    // the convertView if possible. 
} 

/** 
* View to show in Spinner with Nothing Selected 
* Override this to do something dynamic... e.g. "37 Options Found" 
* 
* @param parent 
* @return 
*/ 
protected View getNothingSelectedView(ViewGroup parent) { 
    return layoutInflater.inflate(nothingSelectedLayout, parent, false); 
} 

@Override 
public View getDropDownView(int position, View convertView, ViewGroup parent) { 
    // Android BUG! http://code.google.com/p/android/issues/detail?id=17128 - 
    // Spinner does not support multiple view types 
    if (position == 0) { 
     return nothingSelectedDropdownLayout == -1 ? 
       new View(context) : 
       getNothingSelectedDropdownView(parent); 
    } 

    // Could re-use the convertView if possible, use setTag... 
    return adapter.getDropDownView(position - EXTRA, null, parent); 
} 

/** 
* Override this to do something dynamic... For example, "Pick your favorite 
* of these 37". 
* 
* @param parent 
* @return 
*/ 
protected View getNothingSelectedDropdownView(ViewGroup parent) { 
    return layoutInflater.inflate(nothingSelectedDropdownLayout, parent, false); 
} 

@Override 
public int getCount() { 
    int count = adapter.getCount(); 
    return count == 0 ? 0 : count + EXTRA; 
} 

@Override 
public Object getItem(int position) { 
    return position == 0 ? null : adapter.getItem(position - EXTRA); 
} 

@Override 
public int getItemViewType(int position) { 
    return 0; 
} 

@Override 
public int getViewTypeCount() { 
    return 1; 
} 

@Override 
public long getItemId(int position) { 
    return position >= EXTRA ? adapter.getItemId(position - EXTRA) : position - EXTRA; 
} 

@Override 
public boolean hasStableIds() { 
    return adapter.hasStableIds(); 
} 

@Override 
public boolean isEmpty() { 
    return adapter.isEmpty(); 
} 

@Override 
public void registerDataSetObserver(DataSetObserver observer) { 
    adapter.registerDataSetObserver(observer); 
} 

@Override 
public void unregisterDataSetObserver(DataSetObserver observer) { 
    adapter.unregisterDataSetObserver(observer); 
} 

@Override 
public boolean areAllItemsEnabled() { 
    return false; 
} 

@Override 
public boolean isEnabled(int position) { 
    return position != 0; // Don't allow the 'nothing selected' 
    // item to be picked. 
} 

}

這是spinnertitle.xml

<?xml version="1.0" encoding="utf-8"?> 
<TextView xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@android:id/text1" 
    style="?android:attr/spinnerItemStyle" 
    android:singleLine="true" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:ellipsize="marquee" 
    android:gravity="center" 
    android:background="@drawable/button_custom" 
    android:padding="5dp" 
    android:layout_margin="5dp" 
    android:textSize="18sp" 
    android:text="Vehicle Type" />

這是logcat中的錯誤：

佈局xml文件的名稱是什麼？ – Pooya

'spinnertitle.xml' – Abhi

該佈局在哪個文件夾中？哪一行拋出異常？ –

你的資源佈局，我可以看到沒有父佈局應該像這樣

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 

    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:fitsSystemWindows="true" 

    tools:context=".MainActivity"> 


    <TextView 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_alignParentTop="true" 
     android:text="Lo más valioso que tienes es tu tiempo" 
     android:textColor="@color/white" 
     android:layout_centerHorizontal="true" 
     android:textSize="15dp" 
     android:layout_marginTop="20dp"/> 

</RelativeLayout>

我認爲它不應該有父佈局 – Abhi

它必須有父項 – pratik

不，它不一定有父母。看看['simple_spinner_item']（https://github.com/android/platform_frameworks_base/blob/master/core/res/res/layout/simple_spinner_item.xml） –

進行以下變化和嘗試一次。

protected View getNothingSelectedView(ViewGroup parent) { 
     return layoutInflater.inflate(nothingSelectedLayout, parent, **true**); 
    }

這並沒有工作..雖然感謝嘗試。 – Abhi

你能檢查R.java文件嗎？你所需要做的就是在你的項目中搜索R.java。打開並搜索價值7f04004e –

如果在發佈此問題後重建項目，則可能需要重新記錄日誌並檢查在文件中搜索到的R.java –

嘗試清理您的項目並重建它。
