Fresco SimpleDraweeView像素化圖像

Question

SimpleDraweeView正在從外部存儲裝載像素化位圖圖像。

我通過這個

private OutputStream copy(InputStream in, OutputStream out) throws IOException{ 
    // Transfer bytes from in to out 
    byte[] buf = new byte[in.available()]; 
    int len; 
    while ((len = in.read(buf)) > 0) { 
     out.write(buf, 0, len); 
    } 
    in.close(); 
    out.close(); 
    return out; 
} 

從資產文件夾中的圖像複製到外部存儲，然後我通過這個

Fresco.getImagePipeline().evictFromMemoryCache(uri); 
    Fresco.getImagePipelineFactory().getMainDiskStorageCache().remove(new SimpleCacheKey(uri.toString())); 
    Fresco.getImagePipelineFactory().getSmallImageDiskStorageCache().remove(new SimpleCacheKey(uri.toString())); 

    Postprocessor postprocessor = new BasePostprocessor() { 
     @Override 
     public void process(Bitmap bitmap) { 

      }); 
     } 
    }; 

    ImageRequest request = ImageRequestBuilder.newBuilderWithSource(uri) 
      .setPostprocessor(postprocessor) 
      .build(); 

    PipelineDraweeController controller = (PipelineDraweeController) 
      Fresco.newDraweeControllerBuilder() 
        .setImageRequest(request) 
        .setOldController(header.getController()) 
        .build(); 

    header.setController(controller);

這是設置SimpleDraweeView的圖像一個已知的錯誤。它被固定在Fresco 0.9.0。如果您仍然遇到此問題，請重試並打開新的GitHub問題。
