Downloading images from a link displaying them in a listview

I have a list where for each item i need to display a image. I am downloading the image from a link and displaying it but with i am facing problems to display them as the list gets populated by text first and then downloads the images later.Also another problem is whenever i go up or down in the list image disappears and download again so the images are gone when i come to to the top the list items

Then in my activity i called the async reciver task to load all the data along with link and gave set them in my model class.

You haveto set ResponseCache in your Main class while downloading bitmap:
Like this:
try {
File httpCacheDir = new File(getApplicationContext().getCacheDir(), "http");
long httpCacheSize = 10 * 1024 * 1024; // 10 MiB
HttpResponseCache.install(httpCacheDir, httpCacheSize);
} catch (IOException e) { }
and
connection.setUseCaches(true);

Downloading Image from URL

I got a List View in my application in which I am displaying the data through Base Adapter. Their is two problems I am facing and referred few posts like but all suggested same procedure i followed.
Issues are
I am trying to download the image from the URL given from JSON. everything is working smoothly but the image never get set to Image View.
I bound Text to Speech on click event of button in Base Adapter class and freed it in onDestroy of of the java class but still I get a error in Log for it stating this and application crashes. Here in log erroe line no 55 is the first statement of onDestroy.
Here is my code
Java File
public class DisplayWeather extends Activity {
String city, date, maximumTemp, minimumTemp, description, weatherImageUrl;

It looks like maybe you're returning your convertView in the getView method before your AsyncTask is finished downloading the image. Can you use a thread instead, and use the Thread join method so that your app waits for the image to be downloaded? For an AsyncTask you usually use a progress dialog until the task is finished, but I don't think you can do that inside of an adapter.
How about replacing this:
new ImageDownload().execute();
with this:
new Thread(new Runnable() {
public void run() {
try{
Log.e("src",weatherURL);
URL url = new URL(weatherURL);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);
connection.connect();
InputStream input = connection.getInputStream();
myBitmap = BitmapFactory.decodeStream(input);
Log.e("Bitmap","returned");
return myBitmap;
}
catch(Exception e){
e.printStackTrace();
return null;
}}
}).join();
and then obviously get rid of the ImageDownload class. I'm just throwing this at you, didn't test it or anything. I think that should get you closer.

What Louis suggested is the correct way. I am sure this will work. The reason why it's not working for you is not sure but try this way:
Runnable runnable = new Runnable() {
#Override
public void run() {
// TODO Auto-generated method stub
try{
Log.e("src",weatherURL);
URL url = new URL(weatherURL);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);
connection.connect();
InputStream input = connection.getInputStream();
myBitmap = BitmapFactory.decodeStream(input);
Log.e("Bitmap","returned"+myBitmap);
if(myBitmap!=null)
{
Log.i("OnPost>>>", ""+myBitmap);
weatherImage.setImageBitmap(myBitmap);
}
}
catch(Exception e){
e.printStackTrace();
}
}
};
Thread t = new Thread(runnable);
t.start();
try {
t.join();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Probably, the start method was missing for you and you might not have called it.
I hope this work.

You have
AQuery aq = new AQuery(Customgrid.this); // declared and initialized in oncreate
in onCreate becomes local to onCreate.
Change to
aq = new AQuery(Customgrid.this);
The instance variable aq was never initialized giving NPE.
public class Customgrid extends Activity {
public int gotbread;
public int get, send;
AQuery aq; // not initialized
Also no network related operation on the ui thread.

I would suggest you to check below solutions for loading images from URL:
Android - Universal Image loader by Nostra
Lazy load of images in ListView
Result you can get if you use Universal image loader:

call this function with url you will get Drawable , and then store this drawables into custom class and then place in grid view.
call function like this
ImageOperations(this, imageurl)
public Object fetch(String address) throws MalformedURLException, IOException {
URL url = new URL(address);
Object content = url.getContent();
return content;
}
private Drawable ImageOperations(Context ctx, String url) {
try {
InputStream is = (InputStream) this.fetch(url);
Drawable d = Drawable.createFromStream(is, "src");
return d;
} catch (MalformedURLException e) {
return null;
} catch (IOException e) {
return null;
}
}

https://github.com/koush/UrlImageViewHelper
UrlImageViewHelper will fill an ImageView with an image that is found at a URL.
The sample will do a Google Image Search and load/show the results asynchronously.
UrlImageViewHelper will automatically download, save, and cache all the image urls the BitmapDrawables. Duplicate urls will not be loaded into memory twice. Bitmap memory is managed by using a weak reference hash table, so as soon as the image is no longer used by you, it will be garbage collected automatically.
else use this,
public static Bitmap loadBitmap(String url) {
Bitmap bitmap = null;
InputStream in = null;
BufferedOutputStream out = null;
try {

Http image parsing problem

I'm trying to set different images by parsing, but I can set only last image. I don't know where the problem is in this code:
public class GridActivity extends Activity{
private EfficientAdapter adap;
String strUrl;
AddAlbumDetailBean aBean;
XmlParser parser;
ArrayList<Object> result;
ArrayList<Object> data;
ImageButton btnAdd;
private Context context;
static Bitmap bitmap;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
Utils.onActivityCreateSetTheme(this);
setContentView(R.layout.photos_activity);
GridView gView = (GridView)findViewById(R.id.gridview);
adap = new EfficientAdapter(this);
gView.setAdapter(adap);
/*btnAdd = (ImageButton)findViewById(R.id.btnAddPhotos);
btnAdd.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
startActivity(new Intent(GridActivity.this,AddAlbum.class));
}
});
*/
}

Through this code i am trying to set image into the dynamic gridview using adapter....
but i can set only last image into the gridview so i dont know how to use bitmap array

There are a lot of problems on your code:
your bitmap is static, so you overriding it...
you have no loop, so you have only the same bitmap "parsed"
(after that I stopped looking)
Try to clean up your code and try to debug step by step so that you understand what your code does...
update:
some tips:
use AsyncTask to request the XML and parse it there
when finished fill the adapter with the parsed image urls
