How to get specific list item and pass the two values from one activity to another?

I am developing an Android app and I in my SecondActivity I have parsed some JSON values as a listview and I want to open up ThirdActivity when a particular list item is clicked and send the values "name" and "number" to the ThirdActivity.
I have tried by creating an Intent in the OnPostExecute method. But am unable to figure out how to pass the values on to the next activity.

//intent.putExtra("Lesson", listView1.getItemAtPosition(i).toString());
startActivity(intent);
}
});
}

}

Can you try this please
listView1.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int i, long id) {
Intent intent = new Intent(SecondActivity.this, ThirdActivity.class);
HashMap<String, String> lesson = lessonList.get(i);
intent.putExtra("number", lesson.get("number"));
intent.putExtra("name", lesson.get("name"));
startActivity(intent);
}});

Similar question has been asked before. You have most of it in place, just use Intent.PutStringArrayListExtra and then getIntent.getStringArrayListExtra to pass objects between the activities.
Check this:
Intent.putExtra List

Adding onClick to RecyclerView Android [duplicate]

This question already has answers here:
RecyclerView Single Item ID
(2 answers)
Closed 5 years ago.
I have put together some code as shown below which gets data from a JSON file hosted on a server and puts it into a RecyclcerView. This has been working fine but any way I try to add a click method it does not work. I am looking to make it so that if I click one of the rows it will tell me the country it is. I have no idea where I am going wrong but I will attach my code below which gets the JSON data and puts it into the RecyclerView.
Thanks

Instead of adding a click listener on the Recycler view, try adding click listener in the adapter class, in the onBindViewHolder method. That is how you will get the exact item on which the click was executed.
#Override
public void onBindViewHolder(Viewholder holder, final int position) {
YourClassObject item = YourClassObjectList.get(position);
holder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(view.getContext(), "Recycle Click" + position, Toast.LENGTH_SHORT).show();
}
});

Create a interface in your Adapter class
public interface EventsCatalogsAdapter{
void onClickImageCategory(Catalogs catalog);
}
Create a atribute of EventsCatalogsAdapter
private EventsCatalogsAdapter event;
Create constructor
public CatalogsAdapter(EventsCatalogsAdapter event) {
this.event = event;
}
Add setOnClickListener in onBindViewHolder
public void onBindViewHolder(final CatalogsViewHolder holder, final int position){
holder.imageCatalog.setOnClickListener(holder);
}
In you RecyclerView.ViewHolder implements onClickListener event.
class CatalogsViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{
private ImageView imageCatalog;
private TextView tvCatalogName;
private View vLegendCatalog;
public CatalogsViewHolder(View itemView) {
super(itemView);
imageCatalog = (ImageView) itemView.findViewById(R.id.i =vCatalogItem);
tvCatalogName = (TextView)itemView.findViewById(R.id.tvCatalogName);
vLegendCatalog = itemView.findViewById(R.id.vLegendCatalog);
}
#Override
public void onClick(View v) {
event.onClickImageCategory(catalogsList.get(getAdapterPosition()));
}
}

how to work on BUY NOW button in android?

I am developing an Android eCommerce application in which there are two different buttons. The first one is an ADD TO CART button and the other one is a BUY NOW button.
When I click on the ADD TO CART button, it successfully places the item in the cart and after I click on the cart button, the app proceeds to the Cart Activity. I did the same for BUY NOW but the issue is how do I update my cart and move to Cart Activity on a single click?

My recommendation would be to follow the standard communication model for Activity and Fragment where the Activity implements a callback interface defined in the Fragment.
Check this link for details.
In your onItemSelected method of the spinner, you can call the callback method of the Activity with the selected spinner value.

This is how you could do in OOPS ways
Step 1) Make a spinner Item Value variable in Activity Class
public class RekomendasiExercise extends AppCompatActivity implements AdapterView.OnItemClickListener{
private String currentSpinnerItem ;
/*
set current spinner item value
*/
public void setCurrentSpinnerItem(String itemValue)
{
this.currentSpinnerItem = itemValue ;
//Do stuffs in activity with new value
}
Step 2) Now in your fragment class update currentItemSpinner value like this
#Override
public void onItemSelected(AdapterView<?> parent, View v,
int postion, long arg3) {
String SpinerValue3 = parent.getItemAtPosition(postion).toString();
//Update spinner selected item value in activity
((RekomendasiExercise) getActivity).setCurrentSpinnerItem(SpinerValue3);
}

Data didnt load, and not error or warning display

i got trouble, im try convert my fragment into activity, and when im try running the apps, all data not load and no warning or error shown, pls someone help

}
if default in Fragment its running perfectly and no problem, but when im try using activity all data not load.

I can't see any code that would run when the activity is created. You have an onCreateView method (which I am guessing you are carrying over from your Fragment based implementation). Unless somewhere in your code (which I cannot see how) you are calling that method, it never gets called since it is not part of the Activity lifecycle. I would copy over the entire code from that method to onCreate method (as a starting point) and delete the method. I would then make the following changes to the first few lines
// View rootView = inflater.inflate(R.layout.activity_list, container, false);
// Noticed that I commented out the above line and changed the line below
final ListView listView = (ListView) findViewById(R.id.list);
I am not suggesting that this will solve all of your problems as there might be (likely) other issues, but you should potentially be the first step. I strongly suggest you get more familiar with the Activity and Fragment classes and become more comfortable with their lifecycles. Also, you should get rid of
public RekomendasiExercise() {
// Required empty public constructor
}
Best of luck
