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< ImageView的>(){ @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));
解决方案
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;
}
});
}
});
