picasso

问题 I want to build an app that displays images in a gridview by using the picasso library. The images are retrieved by a remote server. Should I make an AsyncTask class or is this class handled by Picasso Library itself? All the picasso tutorials I have seen so far seem a bit vague. Thanks, Theo. 回答1: Its very simple to use picasso lib for loading images in gridview, as demonstrated here, class SampleGridViewAdapter extends BaseAdapter { private final Context context; private final List<String>

问题 I am new to Android development. I'm trying to download images via HTTP and storing them inside of ImageViews or Drawables. In this example, I am using ImageViews. Initially, I used an AsyncTask to download these images (roughly ~500KB each), however I decided to use Picasso since I've read it is more reliable. In the code below, I have 20 ImageViews. Each of the image url's is an image that is roughly 400KB. However, after loading all of them, I've noticed my getUsedMem() is greater than

问题 How would I use picasso to crop an image to an imageview? Default seems to scale it down so the whole thing shows fit seems to stretch it. centercrop by itself breaks. fit centercrop seems to be the same as just fit Thanks 回答1: Try using centerCrop() Picasso.with(mContext) .load(url) .centerCrop() .resize(yourImageView.getMeasuredWidth(),yourImageView.getMeasuredHeight()) .error(R.drawable.error) .placeholder(R.drawable.blank_img) .into(yourImageView); You have to add addOnPreDrawListener

问题 I have a simple list adapter in which I want to display food images with some text info. Till now I have known that I can do it with libraries like AQuery or Picasso, but I can't figure it out how to implement it after reading a lot of tutorials. I have added Picasso library in my dependencies. Suppose my Image view id is ImgViewFood activity JSONArray jsonArr = jsonObj.getJSONArray("foodnames"); for (int i = 0; i < jsonArr.length(); i++) { HashMap<String, String> food = new HashMap<>();

问题 I have this JSON link and I parsed it. But when I click on any item I get all the images. What I want is, when user clicks on an item, I want to see the details of only the item clicked. For example, when I click on imo, I need only the image for imo. How can I solve this problem? this is my module : public class AppShowModule { private List<String> Allimage = new ArrayList<String>(); public List<String> getAllimage() { return Allimage; } public void setAllimage(List<String> allimage) {

问题 I'm using Picasso to load images, scale and set to listview item. There is my code: Picasso.with(getActivity()).load(builder.toString()) .config(Bitmap.Config.RGB_565) .into(new Target() { @Override public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) { int width = Double.valueOf(bitmap.getWidth() * 0.75).intValue(); int height = bitmap.getHeight(); Bitmap newBitmap = Bitmap.createBitmap(bitmap, 0, 0, width, height); imageView.setImageBitmap(newBitmap); } @Override public void

问题 A question about a thing that I don't understand: does Picasso use OkHttp as default downloader, or should I configure it by myself? And - if not - why should I use Picasso with OkHttp ? What are the advantages compared to the default Picasso ? Thanks. (currently I'm using Picasso v.2.5.2 ) 回答1: If OkHttp is available in your project, Picasso will use it. If not, Picasso will fall back to HttpUrlConnection . 来源： https://stackoverflow.com/questions/32143949/picasso-and-okhttp
