android - 在 picasso 中加载图像后无法隐藏进度条？

Question

我试图在 ma 应用程序中集成进度条。但我无法跟踪回调方法。进度条总是显示。如何在加载图像时隐藏？

holder.imageView = (ImageView) localView.findViewById(R.id.imageView1);
holder.progressBar = (ProgressBar) localView.findViewWithTag(R.id.progressBar1);

localView.setTag(holder);
url = getItem(paramInt);
Picasso.with(getApplicationContext())
.load(url)
.placeholder(R.drawable.ic_launcher)
.error(R.drawable.ic_launcher)
.fit()
.into(holder.imageView, new Callback() {

    @Override
    public void onSuccess() {
        holder.imageView.setVisibility(View.VISIBLE);
        holder.progressBar.setVisibility(View.INVISIBLE);        
    }

    @Override
    public void onError() {
        holder.progressBar.setVisibility(View.VISIBLE);
        holder.imageView.setVisibility(View.INVISIBLE);
    }
});

Answer 1

最后我修复了它。Picasso 2.0.0 beta 中有一个错误。使用官方库
