由 邮差的信 提交于 2019-12-25 16:55:39
问题 I have an Activity with a grid layout where display images from SD folders. When I select a folder, all images are added to a String list (clean when folder is changed), and images construction is in getView() method, using these strings from the list. It works properly for 5 or 6 times (images from folder are displayed), but then I change the folder and I get an 'outofmemoryerror' in the getView() from the custom BaseAdapter (see code line), but I don't understand my leak problem... Images

问题 I have a listview which loads images in every cell in async. When I try to scroll down slowly(after all the images in the current view are loaded), it works flawlessly. But when I try to scroll down before they are even loaded and scroll up, I face this issue. The cells start to show up images which don't correspond to them. My getView method looks like this: public View getView(final int position, View convertView, ViewGroup parent) { // TODO Auto-generated method stub View rowView = null;

问题 I'm trying to create a image ListView using universal-image-loader. Currently, no images appear or load. I found that getView() from ImageAdapter was called to many times. For example, if list size is 3, then getView() should call 3 times but in my code, call 24 times!!! This is my Source Code. public class MainActivity extends Activity{ AsyncTask<Void, Void, Void> asyncTask, registerTask; DisplayImageOptions options; ArrayList<HashMap<String, Object>> feedList = null; @Override public void
