今天嘗試編譯Android SDK中APIDemos中的程序,調試到HelloGallery的時候,在下面這段代碼中:
public ImageAdapter(Context c) {
mContext = c;
TypedArray a = obtainStyledAttributes(android.R.styleable.Theme);
mGalleryItemBackground = a.getResourceId(
android.R.styleable.Theme_galleryItemBackground, 0);
a.recycle();
}
編譯出錯,提示說android.R.styleable unresolved,在網上查了下,說R.styleable在SDK1.5中已經不再支持,所以會出現這個錯誤。解決方法如下:
1.在res/values目錄下新建attrs.xml,在其中添加如下內容:
<?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,將出錯的那段代碼:
public ImageAdapter(Context c) {
mContext = c;
TypedArray a = obtainStyledAttributes(android.R.styleable.Theme);
mGalleryItemBackground = a.getResourceId(
android.R.styleable.Theme_galleryItemBackground, 0);
a.recycle();
}
修改爲:
public ImageAdapter(Context c) {
mContext = c;
TypedArray a = obtainStyledAttributes(R.styleable.Gallery);
mGalleryItemBackground = a.getResourceId(
R.styleable.Gallery_android_galleryItemBackground, 0);
a.recycle();
}
