问题 I'm a little confused: as a rule when async loading images to some sort of list view (whether on Android or iOS or in the abstract on another platform), you essentially must do this .. -- make a note of "which" cell this is (say, #213) -- start getting the image from the net. -- it has loaded from the net. What cell are we now? -- if we are "still" 213, load the image to the image view! -- if we are "no longer" 213, just forget about it. this is a basic in lazy-loading async images. For

问题 I am trying to make a grid view gallery app. When a user clicks on an image, the full image is displayed. I just can't understand how I would implement ImageSlider and save the image to the gallery in my existing project. This is MainActivity: public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); GridView gridView = (GridView) findViewById(R.id.grid);

问题 I am using Picasso library to load and display images in a ViewPager. The images being loaded have high resolution, I would like to add an insampling size to them. I do not know, however, how or where I should add this insampling size attribute. My ViewPagerAdapter.java class has the following. @Override public Object instantiateItem(ViewGroup container, int position) { ImageView iv_page_image; inflater = (LayoutInflater) mContext .getSystemService(Context.LAYOUT_INFLATER_SERVICE); View

问题 I am downloading low resolution pictures from web by using Picasso and displaying it in high res displays. Fetching images is straightforward: Picasso.with(context) .load(item.getPicture()) .transform(new BitmapTransformations.OverlayTransformation( context.getResources(), R.drawable.ic_play_video)) .error(R.drawable.picture_placeholder) .into(target); Notice that I apply Overlay transformation into request - It's a high quality image asset I put on top of downloaded image. Applying overlay

问题 I'm trying to display te pictures in a SimpleAdapter listview. I included Picasso in my project but i don't know how to use Picasso with a SimpleAdapter. List<HashMap<String, String>> featured = new ArrayList<HashMap<String, String>>(); for (int i=0;i<ids.length;i++){ HashMap<String, String> hm = new HashMap<String, String>(); hm.put("productname", names[i]); hm.put("productprice", prices[i]); hm.put("productimage", images[i]); featured.add(hm); } String[] from = {"productname", "productprice

问题 I'm trying to layout a custom infoWindow programmatically. I want to load a streetView preview image using Picasso but the image isn't showing up, any idea why? private View prepareInfoView(Marker marker){ //prepare InfoView programmatically LinearLayout infoView = new LinearLayout(EarthquakeActivity.this); LinearLayout.LayoutParams infoViewParams = new LinearLayout.LayoutParams( LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT); infoView.setOrientation

问题 First of all I know this error has been asked already but my case is a little different: I'm distributing SDK (Android library project). My SDK needs among others things (play services, support v4, gson jars etc.) Picasso so I have in my gradle.build : compile 'com.squareup.picasso:picasso:2.5.2' Now when I test importing the resulted aar file from this library project to my sample app - all works fine. The problem is that my customer when importing the aar file into his app project, trying

问题 There are many popular Image loader available in Github for image loading and caching and Managing Image Request. Universal Image Loader Volley Picasso Fresco (added enhancement ) I came across the requirement if the Imageview if no longer attached to window the request (batch and flight ) will be cancelled . However the scrolling widget like Listview and Gridview the Imageview is frequently attached and detached from window and so the request in queue are canceled respectively . My concern

问题 I looked over the documentation of Picasso and couldn't see anything about threading. What will happen if I run something like this (for ListView ): for(String url : urlArray) { Picasso.with(context).load(url).into(Holder.imageView); } would the images load parallely or one by one? 回答1: Picasso uses a thread pool executor for loading images in background. Once downloading is complete it loads the image using UI thread. You can also configure it to use thread pool executor supplied by you, if

问题 I've been using Picasso's library to load images into my gridview in my application and it works and looks exactly as I'd like. But users are telling me that the images are loading very slowly. I know that this is because of poor network speed and Picasso is loading my full images which are very big and then resizing them to fit my image view. So I tried using glide which loads the images in almost twice the speed but on some images it's not keeping the structure like Picasso does. For
