I have created a gridview, which shows videos from server. GridItem has video thumb image, and video duration.for loading video's thumb I am using UniversalImageloader and loading video duration by creating lazyloading using asynctask.Lazyloading works fine. but if someone scrolls gridview freequently,then video duration shows at wrong position. for creating Lazyloading I am following bellow link

Get rid of view and use convertView as you receive from method. Change to the following
//final is optional but if you need to use in thread
final MediaItemViewHolder mediaItemViewHolder = null;
if (convertView == null) {
convertView = mInflater.inflate(R.layout.camera_roll_item, parent, false);
mediaItemViewHolder = new MediaItemViewHolder();
mediaItemViewHolder.highlightTagIcon = (ImageView) convertView.findViewById(R.id.iv_media_grid_item_highlight_tag);
mediaItemViewHolder.mediaTypeIcon = (ImageView) convertView.findViewById(R.id.iv_media_grid_item_type);
mediaItemViewHolder.mediaClipLength = (TextView) convertView.findViewById(R.id.tv_media_grid_item_length);
mediaItemViewHolder.mediaThumbnail = (ImageView) convertView.findViewById(R.id.iv_media_grid_item_thumbnail);
mediaItemViewHolder.cameraItemSelectedView = (RelativeLayout) convertView.findViewById(R.id.rl_item_selection_parent);
mediaItemViewHolder.progressContainer = (RelativeLayout) convertView.findViewById(R.id.rl_grid_loader_parent);
convertView.setTag(mediaItemViewHolder);
} else {
mediaItemViewHolder = (MediaItemViewHolder)convertView.getTag();
Log.i(TAG, "set blank to ");
}
Now use mediaItemViewHolder.durationTextView.setText(....)
Update 1: I have figured out the problem. Why lazyloading update video duration at wrong gridview position. Discard the above if you want
downloadDuration(resId, durationTextView, mediaItemViewHolder.highlightTagIcon, mediaItemBean);
is the culprit. downloadDuration runs in async mode and it has the reference of durationTextView in before hand. Suppose the downloadDuration is not finished and user scrolls the ListView. After scrolling the ListView downloadDuration is finished, then this durationTextView will be updated with the value but for the wrong ListView item position and not for which position this was passed in downloadDuration. Making final TextView durationTextView;
it as final will also not solve the problem.
Solution could be to show some kind of empty indicatior for duration and let the downloadDuration finishes it's async job. Remove durationTextView as a parameter and add position as a parameter. After async job is done, you can update the bean list of type MediaItemBean for that position. Now notify the adapter that some value has been changed and the ListView will update itself accordingly. FYI RecyclerView item update is more optimised than ListView.
Update 2: You can fetch the items in advance and just map it to bean. Only one time async will run.
Update 3: In the meantime you can check bean for the particular ListView item if it is 0 or not. If it is 0 show in the durationTextView.setText("00:00:00") else call downloadDuration and let it finish and update the duration value in bean. But still you need to notify for updating item.

Above is the code of getview, I was in the use of staggeredgridview Etsy ，when I scroll the screen,this problem is occurs, a time when the position is out of confusion, as if the location of the position did not be remembered.
The following is a screenshot of position getview：
This issue comes only if you are not controlling getCount() and getItem() methods. Make sure that you are returning your list size as in getCount() like this :
#Override
public int getCount() {
return list.size();
}
and getItem() as :
#Override
public SetterGetterClassName getItem(int position) {
return list.get(position);
}
This is my complete code :

I am trying to build a demo chatting App.I want to show the messages with section headers as Dates like "Today","Yesterday","May 21 2015" etc.I have managed to achieve this but since the new View method gets called whenever I scroll the list.The headers and messages get mixed up.
For simplicity, I have kept the header in the layouts itself and changing its visibility(gone and visible) if the date changes.
Can you help me out with this? Let me know if anyone needs any more info to be posted in the question.

Here is how I set up the list view and how I get the image by downloading it.
Some variable explanation :
The PostItem is the model object that contain the data for a listview item
The ImageLoader is the async task class to download the image by getting the image url from PostItem
The problem are , the ordering of the image in the listview is incorrect , for example, the image should appear in 1st is appear in both 1st , 4th, and if I scroll , the display pattern change as well.
Also, I find the image are download again if I scroll, even I have check the imageView whether has drawable
Thanks for helping.
====================================================
Here is how I generate the listview:
static class ViewHolderItem {
TextView name;
TextView date;
ImageView img;
TextView msg;
TextView count;
ImageView likeBtn;
ImageView commentBtn;
ImageView shareBtn;
}
private class MyPostAdapter extends ArrayAdapter<PostItem> {
#Override
public boolean isEnabled(int position) {
return false;
}
public MyPostAdapter(Context context, int resource, List<PostItem> items) {
super(context, resource, items);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
ViewHolderItem viewHolder;
if (v == null) {
LayoutInflater vi;
vi = LayoutInflater.from(getContext());
v = vi.inflate(R.layout.post_item, parent, false);
viewHolder = new ViewHolderItem();
viewHolder.name = (TextView) v.findViewById(R.id.postName);
viewHolder.date = (TextView) v.findViewById(R.id.postDate);
viewHolder.img = (ImageView) v.findViewById(R.id.postImg);
viewHolder.msg = (TextView) v.findViewById(R.id.postMsg);
viewHolder.count = (TextView) v.findViewById(R.id.count);
viewHolder.likeBtn = (ImageView) v.findViewById(R.id.likeBtn);
viewHolder.commentBtn = (ImageView) v.findViewById(R.id.commentBtn);
viewHolder.shareBtn = (ImageView) v.findViewById(R.id.shareBtn);
v.setTag(viewHolder);
} else {
viewHolder = (ViewHolderItem) convertView.getTag();
}
final PostItem post = getItem(position);
if (post != null) {
viewHolder.name.setText(post.name);
try {
c.setTime(sdf.parse(post.createDate));
} catch (ParseException e) {
e.printStackTrace();
}
relative_date = DateUtils.getRelativeDateTimeString (ctx, c.getTimeInMillis() , DateUtils.MINUTE_IN_MILLIS,DateUtils.WEEK_IN_MILLIS, 0).toString();
viewHolder.date.setText(relative_date);
viewHolder.msg.setText(post.txtMsg);
viewHolder.count.setText(post.likeCount + " " + getString(R.string.pro_like) + " " + post.commentCount + " " + getString(R.string.reply));
if (post.isLike) {
viewHolder.likeBtn.setImageResource(R.drawable.like);
} else {
viewHolder.likeBtn.setImageResource(R.drawable.before_like);
}
if (!post.imageURL.equals("null") && viewHolder.img.getDrawable() == null ) {
new ImageLoader(ctx).execute(viewHolder.img,Constant.comment_imageFolder + post.imageURL);
} else {
viewHolder.img.setImageDrawable(null);
}
viewHolder.likeBtn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
new APIManager("like", ctx, Constant.likeAPI + "/"
+ post.commentID + "/" + userID, jsonListener,
getResources().getString(R.string.update_data));
}
});
viewHolder.commentBtn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
ArrayList<PostItem> filterReplyList = new ArrayList<PostItem>();
Intent i = new Intent(ctx, ReplyActivity.class);
i.putExtra("commentID", post.commentID);
// get reply list
for (PostItem reply : replyItemList) {
if (reply.postID.equals(post.commentID)
|| reply.commentID.equals(post.commentID)) {
filterReplyList.add(reply);
}
}
i.putExtra("replyItemList", filterReplyList);
startActivityForResult(i, 0);
}
});
viewHolder.shareBtn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);

sendIntent.putExtra(Intent.EXTRA_TEXT, data);
sendIntent.setType("text/plain");
startActivity(sendIntent);
}
});
}
return v;
}
}
And Here is the imageloader, take the imageview, url as input and put the bitmap in the imageview
public class ImageLoader extends AsyncTask<Object, Void, Bitmap> {
private static String TAG = "ImageLoader";
private InputStream input;
private ImageView view;
private ProgressBar loadingIcon;

// String fileName = imgUrlArray[imgUrlArray.length - 1];
// String newfileName = URLEncoder.encode(fileName, "utf-8");
// imageURL = ((String) params[1]).replace(fileName, newfileName);
imageURL = ((String) params[1]);
if (params.length > 2 && (ProgressBar) params[2] != null)
loadingIcon = (ProgressBar) params[2];
URL url = new URL(imageURL);
HttpURLConnection connection = (HttpURLConnection) url
.openConnection();
connection.setDoInput(true);
connection.connect();
input = connection.getInputStream();
final BitmapFactory.Options options = new BitmapFactory.Options();
BufferedInputStream bis = new BufferedInputStream(input, 4*1024);
ByteArrayBuffer baf = new ByteArrayBuffer(50);
int current = 0;
while ((current = bis.read()) != -1) {
baf.append((byte)current);
}
byte[] imageData = baf.toByteArray();
BitmapFactory.decodeByteArray(imageData, 0, imageData.length, options);
options.inJustDecodeBounds = true;
options.inSampleSize = 2;
options.inJustDecodeBounds = false;
return BitmapFactory.decodeByteArray(imageData, 0, imageData.length, options);
} catch (IOException e) {
e.printStackTrace();
return null;
} finally {
try {
if (input != null)
input.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
#Override

if (result != null && view != null) {
if (loadingIcon != null)
loadingIcon.setVisibility(View.GONE);
view.setVisibility(View.VISIBLE);
view.setImageBitmap(result);
}
}

For the task you are trying to do I would strongly recommend you to use Volley library.
Read from here
All you need to do is as below
mRequestQueue = Volley.newRequestQueue(context);
mImageLoader = new ImageLoader(mRequestQueue, new BitmapLruCache());
mImageView.setImageUrl(BASE_URL + item.image_url, mImageLoader);
Where mImageView is com.android.volley.NetworkImageView instead of a regular ImageView.
Volley takes care of maintaining the cache and the ordering of the images.
if you scroll the listview you will get back recycled convertview, it is not null but it has incorrect imageview. convertView is a view thats created and recycled through scrolling the list. this view makes GC be called less and also save memory for you. it first assigned by your earliest items of list. after you scroll the list, for example item one of list disappears and you see item 15 the convertView of item one is passed again to you. in this time it is not null and it holdes the reference of last imageview, the imageview of item 1.
so this is your problem, you skipped assigning correct imageview to your viewHolder.img.
Ok, what should you do?
the best thing you can do is create in memory cache that holds your downloaded imageview by their URLs as keys of the cache. in getview you check the cache, if it has your URL of current imageview position read from it and set it to viewHolder.img else download the image from internet.
Golden rule is:
ALWAYS OVERWRITE VIEWHOLDER VALUES WITH VALUES OF YOUR ITEM AT INDEX POSITON THAT
GETVIEW PASSES TO YOU
how to create cache? look at Example LRU cache at
http://developer.android.com/training/volley/request.html
and if you want you can also use volley library instead.
if (!post.imageURL.equals("null") && viewHolder.img.getDrawable() == null ) {
new ImageLoader(ctx).execute(viewHolder.img,Constant.comment_imageFolder + post.imageURL);
}
I am guessing that the problem lies here. What happens when you get a recycled view which already has an image from the previous view it was used for? That explains why the image appears in both 1st and 4th position and the change in the display pattern when you scroll.
Get the point? Remove the viewHolder.img.getDrawable() == null and try. See if that helps.
HI all,im trying a develop a sms app from scratch(smsdroid as my reference) . Basically i have Viewpager which shows the conversation list in a a fragment. The fragment has a listview in it. The list view adapter has two different layouts to show sender's and receivers separately. My listview adapter extends Resource cursor adapter.Everything is working well when the app loads.Now in to the problem the image of the receiver is get replaced by the image of the sender on scrolling the listview. Can some one suggest me a way to overcome this problem?
After scrolling the list looks like this
I have read about listview view recyling and all but to be frank i did not understand it completly.
This is my message adapter for the listview

I solved the problem since there was two different layouts to inflate i had to use two different viewholders.
