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()));
}
}

}
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

Convert Fragment Code to Activity Code

I am trying to convert my Fragment Code to Activity code, but when I try to run the Activity, the Activity opens but the data is null. Here my code

onCreateView
is not a part of activity's lifecycle. You need to move stuff from this method to onCreate:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_list);
final ListView listView = (ListView) findViewById(R.id.list);
adapter = new CustomListAdapter(this, exerciseList);
listView.setAdapter(adapter);
pDialog = new ProgressDialog(this);
// Showing progress dialog before making http request
pDialog.setMessage("Loading...");
pDialog.show();
if(exerciseList.isEmpty()) {
// Creating volley request obj
JsonArrayRequest exerciseReq = new JsonArrayRequest(url,
new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
Log.d(TAG, response.toString());
hidePDialog();
exerciseList.clear();
// Parsing json
for (int i = 0; i < response.length(); i++) {
try {
JSONObject obj = response.getJSONObject(i);
Exercise exercise = new Exercise();
if (obj.getString("nama").equals("abdominal")) {
exercise.setNama(obj.getString("nama"));
exercise.setGambar1(obj.getString("gambar1"));
// Genre is json array
// adding movie to movies array
exerciseList.add(exercise);
}
} catch (JSONException e) {
e.printStackTrace();
}
}
// notifying list adapter about data changes
// so that it renders the list view with updated data
adapter.notifyDataSetChanged();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(TAG, "Error: " + error.getMessage());
hidePDialog();
}
});
// Adding request to request queue
AppController.getInstance().addToRequestQueue(exerciseReq);
}else{
hidePDialog();

listView.setOnItemClickListener(this);

Two activities sending data to each other

Two activities are sending data to each other.
The first activity has a custom list view. The second has one text view and three buttons to increase and decrease a value.
When I click on the first activity, the second activity opens. The second activity increases the text view value and clicked the button. Data goes to the first activity. Same process again.
My problem is that the total value is not displayed in the first activity.
How can i show all increase and decrease values from the second activity in the first activity?

In android you need to perform any actions on views from the main UI thread. This post Running code in main thread from another thread will give you an idea of how to do so.
