自定义文本视图属性错误

Question

我正在使用自定义字体作为字体的自定义文本视图

我的自定义视图如下所示。

public class MyTextView extends TextView {

    public MyTextView (Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        setType(context, defStyle);
    }

    public MalayalamTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
        setType(context, attrs.getAttributeIntValue(
                "http://schemas.android.com/apk/res/android", "textStyle", 0));
    }

    public MyTextView (Context context) {
        super(context);
        setType(context, Typeface.NORMAL);
    }

    private void setType(Context context, int Style) {
        if (Cls_Utils.GetMyFontTypeFace(context) != null) {
            this.setTypeface(Cls_Utils.GetMyFontTypeFace(context), Style);
        }

    }
}

我的问题是，当我在 XML 中将文本样式设置为“粗体”或“斜体”时，它会在 eclipse 的图形视图中显示错误。

我的 XML 代码：

        android:textColor="@color/blue_dark" />

</RelativeLayout>

怎么办？？我的代码正在运行，并且在模拟器中字体设置正确，但唯一的问题是 xml 图形视图中的此错误消息。

请帮忙。对不起我的英语不好。

如果您只在 xml 图形视图中收到错误，请将其添加到您的代码中

 if(!isInEditMode())
         //use fonts

编辑器将只显示默认字体。
