}
});
}
public View makeView()
{
ImageView imageView = new ImageView(this);
imageView.setBackgroundColor(0xFF000000);
imageView.setScaleType(ImageView.ScaleType.CENTER);
imageView.setLayoutParams(new ImageSwitcher.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
return imageView;
}
}
【问题讨论】：
-
你遇到了什么错误？
-
loadAnimation of previous button 我得到了 AnimationUtils 类型中的方法 loadAnimation(Context, int) 不适用于参数 (new View.OnClickListener(){}, int)
-
同样在“slide_out_left”和“slide_in_right”红色下划线表示“slide_in_right/slide_out_left 无法解析或不是字段”
-
再次感谢你...关于 setFactory !!!!!!!!!!!1
