how to handling button click in tab fragment using RecyclerViewAdapter?

currently i had come out a screen that using tab fragment and RecyclerView like below. I want to know how i going to handle the button click that circle in red. Every time i click, i have get the details of the product that i want to add into the cart. Since the screen that i come out is using RecyclerView , so i'm confusing how to get all the details of the product that i want.
enter image description here
Adapter code
public class ViewHolder extends RecyclerView.ViewHolder {
ImageView row_image;
TextView title;
TextView description;
public ViewHolder(View v, Context c) {
super(v);
mContext = c;
row_image = (ImageView) v.findViewById(R.id.row_image);
title = (TextView) v.findViewById(R.id.row_title);
description = (TextView) itemView.findViewById(R.id.row_description);
}
}
public CatalogPageAdapter(List<CatalogViewData> dataset) {
mDataset = dataset;
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int i) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.catalog_layout, parent, false);
return new ViewHolder(v,parent.getContext());
}
#Override
public void onBindViewHolder(final ViewHolder viewHolder, int i) {
final CatalogViewData fakePageVH = mDataset.get(i);
String points = Double.toString(Double.parseDouble(fakePageVH.getDescription()));
viewHolder.title.setText(fakePageVH.getTitle());
viewHolder.description.setText(points);
String var = fakePageVH.getImage();
new getImage(var, viewHolder).execute();
viewHolder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(v.getContext(), "Title: " + fakePageVH.getTitle(), Toast.LENGTH_SHORT).show();
}
});
}
public class getImage extends AsyncTask<String, String, String> {
String imageUrl;
ViewHolder holder;
Bitmap downloadedBitmap;
Bitmap scaled;
public getImage(String url, ViewHolder h){
imageUrl = url;
holder = h;
}
#Override
protected String doInBackground(String... args) {
try {
URL url = new URL(imageUrl);
downloadedBitmap = BitmapFactory.decodeStream(url.openConnection().getInputStream());
scaled = Bitmap.createScaledBitmap(downloadedBitmap, 150, 100, true);
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return "done";
}
#Override
protected void onPostExecute(String result) {
holder.row_image.setImageBitmap(scaled);
}
}
#Override
public int getItemCount() {
return mDataset == null ? 0 : mDataset.size();
}
}

I guess the green icon isn't an ImageView otherwise would be a silly question. Add an empty ImageView, place it exactly on your circle. Then add it into your viewholder and use viewHolder.dummyImageView.setOnClickListener.
EDIT
xml:
<ImageView
android:id="#+id/dummyImageView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"/>
VievHolder:
public ViewHolder(View v, Context c) {
super(v);
dummyImage = (ImageView) v.findViewById(R.id.dummyImageView);
}
OnClickListener:
ImageView dummyImage;
viewHolder.dummyImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(v.getContext(), "Click!", Toast.LENGTH_SHORT).show();
}
});

ListView not displaying data in fragment

I am using listview to populate data coming from the server. This listview will show that data in a fragmentTab. Now the data is parsing fine and logcat is also showing the data. But the data is not being populated by listview. I tried to see the error through debugging but there is no problem. Even the Holder in adapter catches the data but it's not displayed. I don't know what the problem is. I tried the following questions but didn't got the answer.
Android - ListView in Fragment does not showing up

Thanks in advance.

In onClick() function you have to get instance of textview and pass it to AsyncTask
// if text and img have same parent the you can find textview like this is
TextView tv =(TextView)v.getParent().findViewById(R.id.txt);
// if not then apply call getParent() function multiple time as per your layout
new sendData(tv).execute();
//Create constructor in sendData
public class sendData extends AsyncTask {
private TextView tv;
public sendData(TextView v){
tv=v;
}
...
protected void onPostExecute(Void result) {
super.onPostExecute(result);
urlCount = "http://example.com/getalldata.php?id="
+ strId;
new getCountData(tv).execute();
};
}
private class getCountData extends AsyncTask {
private TextView v;
public sendData(TextView v){
tv=v;
}
....
// in onPostExecute use
tv.setText(String.valueOf(strCount));
}
Edit: you can get correct position by tag position to view and get it inside onClick
// add this line before return
viewHolder.img.setTag(position);
// get position inside onClick()
int position =(Integer)v.getTag();

How to load images effectively and efficiently on scrolling in android

Hello stackoverflow I'm trying to develop an application like Gallery for a particular directory of SD Card. For example I have took WhatsApp Images directory, here is my code

So far every thing is good, but the problem is images gets loaded all at one shot, so scrolling is very slow and some times OutOfMemoryException occurs though decoded file with BitMapFactory, can any one help me to solve this puzzle please.
Edit:
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = null;
if (convertView == null) {
LayoutInflater inflator = context.getLayoutInflater();
view = inflator.inflate(R.layout.list_layout, null);
final ViewHolder viewHolder = new ViewHolder();
viewHolder.text = (TextView) view.findViewById(R.id.label);
viewHolder.text.setTextColor(Color.BLACK);
viewHolder.image = (ImageView) view.findViewById(R.id.image);
viewHolder.image.setVisibility(View.GONE);
viewHolder.cb = (CheckBox) view.findViewById(R.id.item_check_box);
viewHolder.pb = (ProgressBar) view.findViewById(R.id.progressBar);
view.setTag(viewHolder);
} else {
view = convertView;
}
final int pos = position;
ViewHolder holder = (ViewHolder) view.getTag();
holder.text.setText(list.get(position).getName());
holder.image.setTag(list.get(position).getURL());
holder.image.setId(position);
PbAndImage pb_and_image = new PbAndImage();
pb_and_image.setImg(holder.image);
pb_and_image.setPb(holder.pb);
new DownloadImageTask().execute(pb_and_image);
return view;
}
Thanks.

You should use Lazy loading
visit this tutorial for lazy loading here Its very easy.
Let me know if you have any issue on it.
Edit
public class MainActivity extends ListActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String path = Environment.getExternalStorageDirectory()+"/WhatsApp/Media/WhatsApp Images";
final List<Model> list = new ArrayList<Model>();
final File file = new File(path);
final ProgressDialog dialog = ProgressDialog.show(MainActivity.this, "",
"Please Wait...", true);
new Thread(new Runnable() {
public void run() {
dismissDialog(dialog);
for(File fileChild : file.listFiles()){
list.add(get(fileChild.getName(), fileChild.getAbsolutePath()));
}
}
}).start();
ArrayAdapter<Model> adapter = new MyCustomArrayAdapter(this, list);
setListAdapter(adapter);
}
public void dismissDialog(final ProgressDialog dialog) {
runOnUiThread(new Runnable() {
public void run() {
dialog.dismiss();
}
});
}
private Model get(String s, String url) {
return new Model(s, url);
}
}

This could help: UniversalImageLoader
And that's what I did:

* #param java.lang.String - 檔案URL (pic URL or path)
*/
public static void imageLoaderMemoryCache(Context context, final ImageView img, final int failImgID, String url)
{

.displayer(new FadeInBitmapDisplayer(500))
.build();
imageLoader.displayImage(url, img, options, new ImageLoadingListener()
{
#Override
public void onLoadingStarted(String url, View view)
{img.setImageResource(failImgID);} //一開始先顯示預設圖 (display default pic at first)
#Override
public void onLoadingFailed(String url, View view, FailReason failReason)
{img.setImageResource(failImgID);}
#Override
public void onLoadingComplete(String url, View view, Bitmap loadedImage)
{}
#Override
public void onLoadingCancelled(String url, View view)
{}
});
}
Usage (ListView)
public View getView(...)
{
vh.imgCover=(ImageView)convertView.findViewById(R.id.imgCover);
//...
// some stuff
//...
Util.imageLoaderDiskCache(getActivity(), vh.imgCover, R.drawable.cover_sample, "(pic file path)");

Why AsyncTask is not execute in PostExecute method of another AsynkTask?

I am making a sectional listview in which to section first is pending request list and second is already friend there are two button accept and reject in first section of list view.
When I click on accept hit server and change stautus and now my List should be update and first section accepted list should showing in friendlist in second section of listview.

Is am going right way or wrong please any one help me why it is not working...

You have to start your GetAllConnectionDetail task by calling its execute method, seems you don't do that.
