Question

I want the timeline of the app to be like facebook so i followed this tutorial.

the timeline works fine but volley failed to load the profile pic and the post image .

public class FeedListAdapter extends BaseAdapter {
private Activity activity;
private LayoutInflater inflater;
private List<FeedItem> feedItems;
ImageLoader imageLoader = AppController.getInstance().getImageLoader();

public FeedListAdapter(Activity activity, List<FeedItem> feedItems) {
    this.activity = activity;
    this.feedItems = feedItems;
}

@Override
public int getCount() {
    return feedItems.size();
}

@Override
public Object getItem(int location) {
    return feedItems.get(location);
}

@Override
public long getItemId(int position) {
    return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {

    if (inflater == null)
        inflater = (LayoutInflater) activity
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    if (convertView == null)
        convertView = inflater.inflate(R.layout.feed_item, null);

    if (imageLoader == null)
        imageLoader = AppController.getInstance().getImageLoader();

    TextView name = (TextView) convertView.findViewById(R.id.name);
    TextView timestamp = (TextView) convertView
            .findViewById(R.id.timestamp);
    TextView statusMsg = (TextView) convertView
            .findViewById(R.id.txtStatusMsg);
    TextView url = (TextView) convertView.findViewById(R.id.txtUrl);
    NetworkImageView profilePic = (NetworkImageView) convertView
            .findViewById(R.id.profilePic);
    FeedImageView feedImageView = (FeedImageView) convertView
            .findViewById(R.id.feedImage1);

    FeedItem item = feedItems.get(position);

    name.setText(item.getName());

    // Converting timestamp into x ago format
    CharSequence timeAgo = DateUtils.getRelativeTimeSpanString(
            Long.parseLong(item.getTimeStamp()),
            System.currentTimeMillis(), DateUtils.SECOND_IN_MILLIS);
    timestamp.setText(timeAgo);

    // Chcek for empty status message
    if (!TextUtils.isEmpty(item.getStatus())) {
        statusMsg.setText(item.getStatus());
        statusMsg.setVisibility(View.VISIBLE);
    } else {
        // status is empty, remove from view
        statusMsg.setVisibility(View.GONE);
    }

    // Checking for null feed url
    if (item.getUrl() != null) {
        url.setText(Html.fromHtml("<a href=\"" + item.getUrl() + "\">"
                + item.getUrl() + "</a> "));

        // Making url clickable
        url.setMovementMethod(LinkMovementMethod.getInstance());
        url.setVisibility(View.VISIBLE);
    } else {
        // url is null, remove from the view
        url.setVisibility(View.GONE);
    }

    // user profile pic
    profilePic.setImageUrl(item.getProfilePic(), imageLoader);

    // Feed image
    if (item.getImge() != null) {
        feedImageView.setImageUrl(item.getImge(), imageLoader);
        feedImageView.setVisibility(View.VISIBLE);
        feedImageView
                .setResponseObserver(new FeedImageView.ResponseObserver() {
                    @Override
                    public void onError() {
                    }

                    @Override
                    public void onSuccess() {
                    }
                });
    } else {
        feedImageView.setVisibility(View.GONE);
        Log.i("null","image");
    }

    return convertView;
}

}

if you need more info about the code to help me please notify me thanks in advance.

Answer 1

try this

1.you can use Glide library to load image from url look the below code it can help you in simple way

compile this dependency inside gradle file

compile 'com.github.bumptech.glide:glide:4.0.0-RC0'

than load image like this

Glide.with(HomeClass.this)
            .load(url)
            .into(imageview);

2 .try this if you dont want to use third party library

 new DownloadImage(imamgeview).execute(url);

create a Async Task

public class DownloadImage extends AsyncTask<String, Void, Bitmap> {
ImageView bmImage;

public DownloadImage(ImageView bmImage) {
    this.bmImage = (ImageView ) bmImage;
}

protected Bitmap doInBackground(String... urls) {
    String urldisplay = urls[0];
    Bitmap mIcon11 = null;
    try {
        InputStream in = new java.net.URL(urldisplay).openStream();
        mIcon11 = BitmapFactory.decodeStream(in);
    } catch (Exception e) {
        Log.d("Error", e.getStackTrace().toString());

    }
    return mIcon11;
}

protected void onPostExecute(Bitmap result) {
    bmImage.setImageBitmap(result);
}
}

3 use Picasso for image loading in ImageView. dependency inside gradle file

compile 'com.squareup.picasso:picasso:2.5.2'

than load image in image view like this

Picasso.with(activity).load(img_url).noFade().into(imageview);

i hope that it will work in your case
