Android示例HelloGallery中R.styleable unresolved的解决办法
今天尝试编译Android SDK中APIDemos中的程序,调试到HelloGallery的时候,在下面这段代码中:
- public ImageAdapter(Context c) {
- mContext = c;
- TypedArray a = obtainStyledAttributes(android.R.styleable.Theme);
- mGalleryItemBackground = a.getResourceId(
- android.R.styleable.Theme_galleryItemBackground, 0);
- a.recycle();
- }
编译出错,提示说android.R.styleable unresolved,在网上查了下,说R.styleable在SDK1.5中已经不再支持,所以会出现这个错误。解决方法如下:
1.在res/values目录下新建attrs.xml,在其中添加如下内容:
- <?xml version="1.0" encoding="utf-8"?>
- <resources>
- <declare-styleable name="Gallery">
- <attr name="android:galleryItemBackground">
- </attr>
- </declare-styleable>
- </resources>
2.修改HelloGallery.java,将出错的那段代码:
- public ImageAdapter(Context c) {
- mContext = c;
- TypedArray a = obtainStyledAttributes(android.R.styleable.Theme);
- mGalleryItemBackground = a.getResourceId(
- android.R.styleable.Theme_galleryItemBackground, 0);
- a.recycle();
- }
修改为:
- public ImageAdapter(Context c) {
- mContext = c;
- TypedArray a = obtainStyledAttributes(R.styleable.Gallery);
- mGalleryItemBackground = a.getResourceId(
- R.styleable.Gallery_android_galleryItemBackground, 0);
- a.recycle();
- }
3.重新运行就可以了
