我使用Koush /离子库，从互联网上的GIF加载到ImageView的，但我不能aspectly调整GIF格式，在调用功能调整，GIF变得仍

所以我的问题是，有没有什么办法可以在android系统aspectly调整GIF？

这是我的计算得到高度方面和图像的宽度是否有帮助

 最终诠释newWidth = deviceWidth;最终诠释newHeight =（INT）（（INT）newWidth *（imageHeight / imageWidth））; 

解决方案

我想我终于找到了解决方案，与FIT_XY第一级图像，然后设置newHeight作为图像视图高度

  imageView.setScaleType（ScaleType.FIT_XY）;。imageView.getLayoutParams（）高度= newHeight; 

code段

  Ion.with（ImageView的）    .animateGif（AnimateGifMode.ANIMATE）    .load（imgUrl的）    .setCallback（新FutureCallback＆LT; ImageView的＆GT;（）{    @燮pressLint（NewApi）    @覆盖    公共无效onCompleted（例外为arg0，    ImageView的ARG1）{        imageView.getViewTreeObserver（）。插件preDrawListener（        新ViewTreeObserver.On preDrawListener（）{            在preDraw公共布尔（）{                imageView.getViewTreeObserver（）                    .removeOn preDrawListener（本）;                imageView.setScaleType（ScaleType.FIT_XY）;                。imageView.getLayoutParams（）高度= newHeight;                返回true;            }        }）;    }}）; 

I am using Koush/Ion library to load gif from internet into imageview but I cannot resize the gifs aspectly, upon calling resize function, gif becomes still

so my question is, is there any way I can resize gif aspectly in android ?

here's my calculation to get aspect height and width of image if that helps

final int newWidth = deviceWidth;
final int newHeight = (int) ((int) newWidth * (imageHeight / imageWidth));

I think I finally found the solution, First scale image with FIT_XY and then set 'newHeight' as the height of image view

imageView.setScaleType(ScaleType.FIT_XY);
imageView.getLayoutParams().height = newHeight; 

Code Snippet

Ion.with(imageView)
    .animateGif(AnimateGifMode.ANIMATE)
    .load(imgUrl)
    .setCallback(new FutureCallback < ImageView > () {

    @SuppressLint("NewApi")
    @Override
    public void onCompleted(Exception arg0,
    ImageView arg1) {

        imageView.getViewTreeObserver().addOnPreDrawListener(
        new ViewTreeObserver.OnPreDrawListener() {
            public boolean onPreDraw() {

                imageView.getViewTreeObserver()
                    .removeOnPreDrawListener(this);

                imageView.setScaleType(ScaleType.FIT_XY);
                imageView.getLayoutParams().height = newHeight;

                return true;
            }
        });
    }
});
