    <p>In my Android application an Asyntask is used for loading images from web in a list view.I want to show the center portion of the image and I have tried imageloader for loading images but the problem is image clarity is very poor but I have used it for loading thumbnails because thumbnail is very small.So that I have tried an Asyntask which is given below.The problem with this method is image view shows other images that means image view in first list item will show the next list item's image and after some time it will display the correct image.How can I solve this issue.Or suggest a method for lading images with good clarity.Please help me.Thanks in advance</p> <pre><code>private class DownloadImageTask extends AsyncTask&lt;String, Void, Bitmap&gt; { ImageView bmImage; ProgressBar mProgressBar; String url; public DownloadImageTask(ImageView bmImage, ProgressBar progressBar) { this.bmImage = bmImage; this.mProgressBar = progressBar; } @Override protected void onPreExecute() { mProgressBar.setVisibility(View.VISIBLE); super.onPreExecute(); } protected Bitmap doInBackground(String... urls) { String urldisplay = urls[0]; url = urldisplay; Bitmap mIcon11 = null; try { InputStream in = new java.net.URL(urldisplay).openStream(); mIcon11 = BitmapFactory.decodeStream(in); } catch (Exception e) { // Log.e("Error", e.getMessage()); e.printStackTrace(); } return mIcon11; } protected void onPostExecute(Bitmap result) { Utilities.addBitmapToMemoryCache(url, result); bmImage.setImageBitmap(result); mProgressBar.setVisibility(View.GONE); // result.recycle(); } } </code></pre> <p>}</p> <pre><code>public View getView(final int position, View convertView, ViewGroup parent) { vi = convertView; int type = getItemViewType(position); // Utilities.message_player = new MediaPlayer(); if (vi == null) { inflater = LayoutInflater.from(mcontext); if (type == ITEM_TYPE_ONE) vi = inflater.inflate(R.layout.message_group_list_item, null); else vi = inflater.inflate(R.layout.listlastrow, null); } if (type == ITEM_TYPE_ONE) { if (fontType == true) { } ((ImageView) vi.findViewById(R.id.imageMessage)).setTag(position+"i"); Bitmap bmp = Utilities.getBitmapFromMemCache(feedsImage); if(bmp == null){ DownloadImageTask dwnloadImgTask = new DownloadImageTask(((ImageView) vi.findViewWithTag(position+"i")), ((ProgressBar) vi.findViewById(R.id.progressBar1))); dwnloadImgTask.execute(feedsImage); }else{ ((ImageView) vi.findViewById(R.id.imageMessage)).setImageBitmap(bmp); } } } </code></pre>

    1. COPlease show us where and how you are using this AsyncTask (probaly in your list adapter code ?) The mistake may be in the getView method from the Adapter...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
