loading images to a recyclerview using a thread

So I have a Recyclerview which holding items with images, I want to load images into the items but when I do that I got a lot of fps drops.
I read that I need to use another thread for the network part and I tried to do that as you can see, and it seems good to me but I can't figure out how to stop the fps drops and make the scrolling in the Recyclerview smooth, this Recyclerview supposed to hold between 10 and 100. Am I supposed to run the activity in a thread?
Note: The fps drops occur with 10 items.

What am I doing wrong?

Instead of writing your own thread and code to fetch, parse, decode and load the image, give Glide a try. It does all that for you with a simple single line code and loads the image in your ImageView

startActivity(intent);
}
});
return convertView;
}
class ViewHolder{
private Button bOrderNo;
}
}
}
The holder gets executed in loop i guess is why it wouldn't send right Id.
How do i get it to send only Id of the clicked orderId
you can check this link to see how json Response looks like http://146.185.178.83/resttest/order

You have a silly mistake in your code . I have edited single line in your code . I think you are getting same "orderId" every time instead of actual "orderId". Check this one . I hope your problem will resolve .
final int index = position;
holder.bOrderNo.setText("Order No: " + orderModelList.get(position).getOrderId());
holder.bOrderNo.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(Order.this, OrderSelected.class);
intent.putExtra("parameter_name", orderModelList.get(index).getId());
startActivity(intent);
}
});

Please try
In place of
intent.putExtra("parameter_name", orderId);
Please put
intent.putExtra("parameter_name", orderModelList.get(position).getId());

Value not added in arraylist on checkbox click in listview.

The checkbox is clicked but value is not added in the arraylist(named data; type String).

Please tell me what is wrong with my code?
}

Whenever you are making any change in the dataset, call notifyDataSetChanged().
Thus it will be like this:
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked) {
data.add(holder.check.getText().toString());
} else {
data.remove(holder.check.getText().toString());
}
notifyDataSetChanged();
}

Listview With Asynctask get no response from server

I want to send Cus_id from postParamName to web server.
According to cus_id I want to fetch data from server and get it into listview.

Your FetchDataTask constructor accepts FetchDataTaskListener as parameter
public FetchDataTask(FetchDataListener listener) {
this.listener = listener;
}
But you have initialized it using activity's context
FetchDataTask task = new FetchDataTask(this);
Could you please check this.
You should set listener correctly, something like this
this.mListener = (FetchDataListener) activity

Android: Simple XML SAX Parser - Displays Same Data Over and Over

I've created an XML parser which populates a listView with data obtained from an XML file. The problem is for some reason the listView shows the same data over and over instead of unique data for each listView item.
I'm not sure exactly what is causing this issue - any insight is greatly appreciated.

You are creating only one instance of Cmd() that is overriding itself, because you have only one <cmd> element.
Change:
if (qName.equalsIgnoreCase("cmd")) {
// create a new instance of cmd
cmd = new Cmd();
}
to:
if (qName.equalsIgnoreCase("Video")) {
// create a new instance of cmd
cmd = new Cmd();
}
You need to create an instance of Cmd() when your parser read every <Video> element.
and change your endElement(String uri, String localName, String qName) method to:
public void endElement(String uri, String localName, String qName)
throws SAXException {
if (qName.equalsIgnoreCase("videos")) {
// add it to the list
/*} else if (qName.equalsIgnoreCase("success")) {
cmd.setSuccess(tempVal);
} else if (qName.equalsIgnoreCase("numberofvideos")) {
cmd.setNumberOfVideos(tempVal);
} else if (qName.equalsIgnoreCase("videos")) {
cmd.setVideos(videos);
} else if (qName.equalsIgnoreCase("video")) {
cmd.setVideo(tempVal);*/
} else if (qName.equalsIgnoreCase("videoname")) {
cmd.setVideoName(tempVal);
} else if (qName.equalsIgnoreCase("videourl")) {
cmd.setVideoURL(tempVal);
videos.add(cmd); //You only need store an instance of your Cmd
}
}
