R.styleable解決不了

Question

海的朋友......我的Java文件指出這個錯誤： R.styleable解決不了....

我的XML文件：

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:orientation="vertical" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent"> 

<Gallery xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/videoGrdVw" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:numColumns="auto_fit" 
    android:verticalSpacing="5dip" 
    android:horizontalSpacing="5dip" 
    android:columnWidth="80dip" 
    android:stretchMode="columnWidth" 
    android:gravity="center"/> 

<ImageSwitcher 

    android:id="@+id/switcher" 
    android:layout_height="match_parent" 
    android:layout_width="match_parent"> 

    </ImageSwitcher> 
    <resources> 
    <declare-styleable name="HelloGallery"> 
    <attr name="android:galleryItemBackground" /> 
    </declare-styleable> 
    </resources> 


    </LinearLayout> 

源代碼如下：

private class VideoGalleryAdapter extends BaseAdapter 
{ 
    private int itemBackground; 

    public VideoGalleryAdapter(Context c) 
    { 
     _context = c; 
     TypedArray a = obtainStyledAttributes(R.styleable.Gallery1); 
     itemBackground = a.getResourceId(
       R.styleable.Gallery1_android_galleryItemBackground, 0); 
     a.recycle(); 
    } 

Answer 1

對於我來說，這並獲得成功：

import android.R; 

Answer 2

根據這一forum thread您需要更改：

TypedArray a = obtainStyledAttributes(R.styleable.Gallery1); 

到

TypedArray a = c.obtainStyledAttributes(R.styleable.Gallery1); 

Answer 3

values文件夾下創建一個XML文件，名爲attributes.xml及以下內容複製到它。

<?xml version="1.0" encoding="utf-8"?> 
<resources> 
    <declare-styleable name="Gallery1"> 
     <attr name="android:galleryItemBackground"/> 
    </declare-styleable> 
</resources> 

這應該起作用。
