Question

我创建了一个自定义视图，该视图接受背景色resid和阴影色resId。但是，当我转换资源ID以便将它们存储在int变量中时。它给出错误为

Expected a color resource id (R.color.) but received an RGB integer

以下是我的setter方法

    @Override
    public void setBackgroundColor(@ColorRes int backgroundResId) {
        this.backgroundColor = ContextCompat.getColor(context, backgroundResId);
    }

    public void setShadowColor(@ColorRes int shadowColorId) {
        this.shadowColor = ContextCompat.getColor(context, shadowColorId);
    }

使用时显示相同的错误

public void setBackgroundColor(@ColorRes int backgroundResId) {
    this.backgroundColor = context.getResources().getColor(backgroundResId);
}

我想您在方法fadeView.frame = view.frame fadeView.center = view.center fadeView.alpha = 0.0 fadeView.layer.zPosition = 1 fadeView.isOpaque = true view.addSubview(fadeView) UIView.animate(withDuration: 0.3, animations: {self.fadeView.alpha = 1.0})中传递了错误的参数。您应该以这种方式使用它：

setBackgroundColor

从资源ID整数获取颜色给出错误
