Question

由于某种原因，毕加索仅显示20张图像中的6张。它显示前6张图像，然后重复这些图像。我正在从网上获取图像。

有什么主意吗？

Picasso.get().load(response.body().getMediaDetails()
.getSizes().getFull().getSourceUrl())
.fetch(new com.squareup.picasso.Callback() {
  @Override
  public void onSuccess() {}

  @Override
  public void onError(Exception e) {

    // Try again online if cache failed
    Picasso.get()
   .load(response.body().getMediaDetails().getSizes().getFull().getSourceUrl())
    .placeholder(R.drawable.test_img_size)
    .error(R.drawable.test_img_size)
    .into(imageView);

  }
});

因此，正如某些建议所建议，并且您可能会看到，我尝试使用林间空地，但没有成功。问题是相同的，当用户上下滚动图像时，一遍又一遍地重新加载。而且，有时它只缓存20张图片中的6张（它应该以这种方式缓存每张图片，这样应用程序将显示缓存中的图片，而不是从Web提取）

Answer 1

如果您的问题是缓存，请尝试使用方法 skipMemoryCache（）和 memoryPolicy（MemoryPolicy.NO_CACHE）。

毕加索仅从缓存中加载6张图像
