图片很大的时候无法显示

[gyqsophila]

W/OpenGLRenderer: Bitmap too large to be uploaded into a texture (6000x4000, max=4096x4096)

[iielse]

能给个demo吗？非常感谢。

[gyqsophila]

调用代码么？

    @Override
    public void onThumbPictureClick(ImageView i, List<ImageView> imageGroupList, List<String> urlList) {
        vImageWatcher.show(i, imageGroupList, urlList);
    }

出问题的图片就是分辨路 6000*4000，大小 2.7M，别的图片没问题的

@Override
                public void onResourceReady(Bitmap resource) {
                    final int sourceDefaultWidth, sourceDefaultHeight, sourceDefaultTranslateX, sourceDefaultTranslateY;
                    int resourceImageWidth = resource.getWidth();
                    int resourceImageHeight = resource.getHeight();
                    if (resourceImageWidth * 1f / resourceImageHeight > mWidth * 1f / mHeight) {
                        sourceDefaultWidth = mWidth;
                        sourceDefaultHeight = (int) (sourceDefaultWidth * 1f / resourceImageWidth * resourceImageHeight);
                        sourceDefaultTranslateX = 0;
                        sourceDefaultTranslateY = (mHeight - sourceDefaultHeight) / 2;
                        imageView.setTag(R.id.image_orientation, "horizontal");
                    } else {
                        sourceDefaultHeight = mHeight;
                        sourceDefaultWidth = (int) (sourceDefaultHeight * 1f / resourceImageHeight * resourceImageWidth);
                        sourceDefaultTranslateY = 0;
                        sourceDefaultTranslateX = (mWidth - sourceDefaultWidth) / 2;
                        imageView.setTag(R.id.image_orientation, "vertical");
                    }
                    imageView.setImageBitmap(resource);
                    notifyItemChangedState(pos, false, false);

                    ViewState vsDefault = ViewState.write(imageView, ViewState.STATE_DEFAULT).width(sourceDefaultWidth).height(sourceDefaultHeight)
                            .translationX(sourceDefaultTranslateX).translationY(sourceDefaultTranslateY);
                    if (isPlayEnterAnimation) {
                        animSourceViewStateTransform(imageView, vsDefault);
                    } else {
                        ViewState.restore(imageView, vsDefault.mTag);
                        imageView.setAlpha(0f);
                        imageView.animate().alpha(1).start();
                    }
                }

看了一下，应该是我的问题吧，没有考虑 图片大小超过了屏幕尺寸的情况。

好的 ，我会调试的， 可能几天，十几天更新。

[iielse]

@AlphaGao1993 在 imageView.setImageBitmap(resource); 之前，应该对resource的大小先处理一下吧。我应该漏了这里。 你是导入源码方式使用的吗？ 对不起 还是我自己太菜了

[gyqsophila]

我本地也有 Glide ，直接拷贝的源码，这个组件还是挺好的，我反正写不出来，你还是挺厉害的

[iielse]

那你可以调试 断点 onResourceReady 开始。 还有 为什么会加载2.7M的网络图。 我感觉这件事件本身就有点不对吧。 加载的图片url应该都是自己控制过后上传给后台的吧。

@ielse 兄弟你真是太好心了~

[iielse]

我更希望你们大家都能帮忙改代码，也会自己改呀。祝你越来越强

[gyqsophila]

@ielse 好的

https://github.com/bumptech/glide/issues/547

If you're loading into SimpleTarget, notice that the implicit size in the default constructor is SIZE_ORIGINAL, try a more reasonable size in the overloaded constructor.

这个问题是加载的图片太大了，hold不住的原因吧。

https://github.com/bumptech/glide/issues/2313

现在 ImageWatcher.Loader 被抽出来啦，你可以预先设定对应uri所加载的宽高。 方案如2313。

但其实更优的方案应是加载的uri图片本身尺寸就是适合手机的尺寸 比如 https://developer.qiniu.com/dora/manual/1279/basic-processing-images-imageview2
