LIstView Filter From Json Returns First Item Only Everytime

I tried to get help on this post without any luck, I played around with code but still no luck. My list for example is as follows: Blue, Red, Purple from Json remote server.
When I type B.. it returns Blue. OK
When I type X.. it returns no results because no color matched "X". OK
When I type R.. (or RE.. or RED) it returns Blue instead of returning Red.
Conclusion - The code always returns the first item on the list when filtered.
My code:
JSON:
private class JsonReadTask extends AsyncTask<String, Void, String> {

#Override

}
#Override

HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(params[0]);
try {
HttpResponse response = httpclient.execute(httppost);
jsonResult = inputStreamToString(response.getEntity().getContent()).toString();
}
catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {

private StringBuilder inputStreamToString(InputStream is) {

Add Update and Delete Item from Listview on Server Response Dynamically

Hi I don't know asking proper question or not but i want to develop Like Comment on Facebook post, Update comment and Delete Comment.
When i will add comment it will send request to server and it will give response with new values to fill in listadapter and that change may appear on my listview after click on enter or add button, and on delete it will send request to server and in response fill my listAdapter. and change may appear on my listview without refreshing listview. how can i perform this operation .

You might have solved this already but I was working on a different app in Java and came across something similar. Mine was a bit simpler because I am using a local database but ~same thing. In your CommmentActivity's onCreate method pull out the commentAdapter declaration and the CommentList.setOnScrollListener and put them in their own method. Then call your newly defined commentAdapter method in onCreate and after you parse through the response.
Something like this
public void myAdaperMethod(Context context, List<CommentListInfo> list_CommentInfo){
commentAdapter = new ListCommentAdapter(this, list_CommentInfo);
CommentList.setAdapter(commentAdapter);
CommentList.setOnScrollListener(new OnScrollListener(){...}
}
onCreate{
myAdapterMethod(...);
}
post{...}
get{myAdapterMethod(...);}
Hope that helps.

You just need to re-bind your control after the listadapter has the new dataset.
CommentList.DataBind();

Remove notifyDataSetChanged() from getView() , notifyDataSetChanged() will update adapter when the data which you provided for your adapter has been changed , but you are using that wrong when a View of your list has been changed.

Remove notifyDataSetChanged() from getView().
You dot need that here. Rather have Remove notifyDataSetChanged() in onPostExecute() call back of JSONAsyncTask

Use cachecolorHint for come out of your solution:
<ListView
android:id="#+id/listNewsMain"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:cacheColorHint="#android:color/transparent" >
</ListView>

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
