How to Pass Data from Dialog Fragment into Custom Adapters Particular Position - android

I am developing an android app for Restaurant Ordering system, Now I want to add some Description for the particular Item so that I had added the Dialogfragment and set it to the Custom Adapter ImageView Click listener, the dialog fragment showing correctly, as well as data, is also passing from edit text, but it shows in the last element of the listview.
I had tried various procedures and method but it still getting the same please help me, guys.
I am attaching the screen shots of my project

And watch this video for understand problems

You need to follow viewholder pattern. It will resolve your issue. You can check it here https://developer.android.com/training/improving-layouts/smooth-scrolling.html
The only place you're keeping count is in the view. You should make your count a field in the list item ShowProducts and create a getter & setter. For example, in the plus onClickListener, instead of
int a = Integer.parseInt(tvQunatitySetOfSelectedItem.getText().toString());
a++;
You'll have
// for example, in the `plus` listener
int a = showProducts.getCount();
a++;
showProducts.setCount(a);
And don't forget
notifyDataSetChanged();

How to compare two arraylist and enable toggle accordingly in android

I have an app in which listview with two arraylist suppose 1st "listStorage" and second is "existingDataSet" i have to compare these two arraylist value if found same then enable toggle of that index.

newDataSet = new ArrayList<>();
gson = new Gson();
sharedPreference = new MySharedPreference(mContext);
whiteListModel = new WhiteListModel();
//retrieve data from shared preference
String jsonScore = sharedPreference.getAppsArrayListData();
Type type = new TypeToken<ArrayList<WhiteListModel>>() {
}.getType();
existingDataSet = gson.fromJson(jsonScore, type);
}
#Override

listViewHolder.switchCompat.setChecked(true);
}
}
}
can you try this? switch should retain its value false if not contains within 2 list when on getView because it trigger several times.
boolean isChecked = false
for (int i = 0; i<existingDataSet.size(); i++){
for (int j= 0; j<listStorage.size(); j++){
if (existingDataSet.get(i).getPackName().equalsIgnoreCase(listStorage.get(j).getPackName())){
isChecked = true;
}
}
}
listViewHolder.switchCompat.setChecked(isChecked);

Android Listview item, when I implement setCheck(true) in any checkbox some item changed randomly

this is my first post, and I have a doubt about a listview item management, I have seen some post about recycleView, but I donĀ“t understand yet how to implement it in my problem.
Well, I've got a listView that shows some elements like a shopping car where the user clicks the button autorizarDetalleSolicitud, which opens an alertDialog where an user choices a wished amount of that respective item, so if the amount is bigger than zero, the checkbox changes to state TRUE, but when I test this function, I could see that other checkBoxes are activated (or changes to state TRUE) randomly; i.e. When I input an amount to first item, the state of penultimate checkBox changes to TRUE. Thanks for your attention.
//Button of each listview item
public void autorizarDetalleSolicitud(View v) {

SOLUTION!
To solve my problem, I based on this answer recording an array with positions of the checkboxes verifying if they were checked, I mean, this a boolean array, and each checkbox has a status TRUE or FALSE. Thanks to #AnshulTyagi

RecyclerView items positions change or removed when scrolling

I have a problem that I have been trying to solve for too long but I can't know what causes the problem.
I have a marks list that contains Test objects and subject strings that I use as sections between marks, I use getClass() method to determine if an object is a string or Test, if it is a string, I hide the test's RelativeLayout, if it is a test then I hide the RelativeLayout of the subject. But when scrolling, items get removed and and re-added randomly.
my adapter's class:
public class MarksAdapter extends RecyclerView.Adapter<MarksAdapter.MyHolder>{
public class MyHolder extends RecyclerView.ViewHolder{
RelativeLayout card;
TextView title;
TextView total;
View divider;
int posito;
RelativeLayout group;
TextView groupTitle;
TextView groupMark;
public MyHolder(View itemView) {

Note: I already tried the itemViewType method but it didn't work for me
Thanks in advance!
I believe you missed to set holder.card back to visible, like this
if(marks.get(holder.posito).getClass() == Test.class) {
holder.card.setVisibility(View.Visible); //add back this
holder.group.setVisibility(View.GONE);

My project contains listView(homelistView) that contains button(btnList).
When I click on button(btnList) it must go to another Activity. I tried a lot but I didn't find a good example.
Please suggest me a good example regarding this.
Below is my code:
Here is my listview contains button. When on click of button it must go to other activity
--------------------------------A--
button(btnList) B
--------------------------------C---
BUTTON(btnList) D
--------------------------------E--
homempleb.xml Before i used this code in xml. buttonlist worked fine for me as per Mohith verma sample
<ListView
android:id="#+id/homelistView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1.04"
android:dividerHeight="0dip" >
</ListView>
homempleb.xml Currently i added scroll index to my listview and changed the code as per below.. Listbutton is not working for me now..Plz help me
<com.woozzu.android.widget.IndexableListView
android:id="#+id/homelistView"
android:layout_width="match_parent"
android:layout_height="wrap_content"

First remove btnList, btnScan from your MainActivity class.
In your EfficientAdapter class add object Context Context
Change your contructor:
public EfficientAdapter(Context context) {
mInflater = LayoutInflater.from(context);
}
to:
public EfficientAdapter(Context context) {
mInflater = LayoutInflater.from(context);
this.context=context;
}
In your ViewHolder class you need to add Button btnList.
Then in getview method find its view using holder.btnList
Then use:
holder.btnList.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent next=new Intent(context, SeviceDetails.class);
context.startActivity(next);
}
});
in your getview method before return convertView.
try this..
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
View view = convertView;
if (view == null){
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.list_layout_ip_addtional_users, null);
}
//Handle TextView and display string from your list
TextView listItemText2 = (TextView)view.findViewById(R.id.list_item_string_name);
listItemText2.setText(list.get(position));
ImageButton button8 = (ImageButton) view.findViewById(R.id.ip_additional_user_edit);
button8.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(context, IPAdditionalUsersEdit.class);
context.startActivity(intent);
}
});
return view;
}
