第一次错误装载的画面，毕加索 [英] First time error loading picture with Picasso
问题描述
我有一个活动与 ImagePagerAdapter （延伸 FragmentStatePagerAdapter ）具有此的getItem 方法：
I have an Activity with an ImagePagerAdapter (extends of FragmentStatePagerAdapter) that has this getItem method:
@Override
public Fragment getItem(int position) {
Log.d(LOGTAG, "------------>mUserPicturesList.get("+position+").getFilename(): " + mUserPicturesList.get(position).getFilename());
return UserDetailFragment.newInstance(mUserPicturesList.get(position).getFilename());
}
这被实例化的片段有这样onCreateView：
The fragment that is instantiated has this onCreateView:
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate and locate the main ImageView
final View v = inflater.inflate(R.layout.image_detail_fragment, container, false);
mImageView = (ImageView) v.findViewById(R.id.imageView);
mProgressPicturePager = (ProgressBar) v.findViewById(R.id.progress_picture_pager);
String imageUrl = WApp.PHOTO_URL + mImageUrl + "?type=user_gallery_big_img";
Picasso picasso = Picasso.with(getActivity());
picasso.setDebugging(true);
picasso.load(imageUrl)
.placeholder(R.drawable.no_picture_man_big)
.error(android.R.drawable.stat_notify_error)
.into(mImageView, new Callback() {
@Override
public void onSuccess() {
mProgressPicturePager.setVisibility(View.GONE);
}
@Override
public void onError() {
Log.d(LOGTAG, "picasso load error");
mProgressPicturePager.setVisibility(View.GONE);
}
});
return v;
}
的问题：
在 ImagePager 加载第一次，有些时候，毕加索呼叫的onError ，显示 .error 绘制。
如果我$背部按钮p $ PSS和返回到活动具有 ImagePager ，毕加索加载图片正确。
如果 ImagePager 有两个或两个以上的照片，我刷的图像之间，这些都是正确加载有时不退出并重新进入到 ImagePager 。
When the ImagePager load first time, some times, Picasso call onError, showing the .error drawable.
If I press on back button and go back to the Activity that has the ImagePager, Picasso load the picture correctly.
If the ImagePager has two or more pictures and I swipe between the pictures, those are loaded correctly some times without exit and reenter to the ImagePager.
的理论：
我想这可能是缓存的问题，但很多搜索后，我敢打赌，这个问题是在毕加索的弱引用。 请记住，这个问题仅出现在我第一次加载有ImagePager活动。
I think that it could be a problem of cache, but after many searches, I bet that the problem is in the weak reference of the Picasso. Keep in mind that the problem only appears the FIRST TIME I load the activity that have the ImagePager.
在另外一个地方，目前毕加索工作正常，在的ListView 通过一个适配器加载图片的第一次。呼叫毕加索 适配器类。 getView 法里面
In another place, currently Picasso works fine in listView with an adapter loading the pictures at first time. Calling Picasso inside the getView method of Adapter class.
