Question

因此，我参与了一个旧项目，但它不会仅仅运行。天吧

Caused by: java.lang.UnsupportedOperationException: Failed to resolve attribute at index 0: TypedValue{t=0x2/d=0x7f010001 a=-1}

这是课程（已删除部分内容，因为我认为这是不必要的）：

public class MyAppsTabPage extends ListTabPage {
    private int categoryId;

    public MyAppsTabPage(Context context) {
        super(context);
    }

    @Inject protected Provider<AccountSource> accountSource;
    @Inject protected StoreConfigSource storeConfigSource;

    @Override protected void onCreate(AttributeSet attrs) {
        super.onCreate(attrs);
        TypedArray a = getContext().obtainStyledAttributes(attrs, se.appland.market.core.R.styleable.CategoryTabPage);

        //the following line throws the error
        this.categoryId = a.getInteger(se.appland.market.core.R.styleable.CategoryTabPage_appcom_categoryid, CategoryTileFetcher.ROOT_CATEGORY);
        a.recycle();
    }

    public MyAppsTabPage(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public MyAppsTabPage(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }


    @Override protected void onFinishInflate() {
        super.onFinishInflate();
        addUpdateOnAccountChange();
    }

}

我的attrs.xml就像

<declare-styleable name="CategoryTabPage">
    <attr name="appcom_categoryid" format="integer" />
</declare-styleable>

任何线索我想念什么？
