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()));
}
}

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.

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

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

}

I started to develop Android recently and I'm having difficulty in solving a thing probably much simpler than what I think.
I am creating a CRUD application that communicates with an online database, I can read and enter data, unfortunately I can't delete and modify the list once it is created.
To manage the data that use JSON and the row in the list that I add is made up of three fields: animal_id, animal_name, animal_type.
The activity data on which I read and on which I want to implement methods to modify and delete via listener is formed by the following code:
import java.sql.Array;
import java.util.ArrayList;

When i click on a list Item, the listener show me the object in this format:
{animal_type=firstType, animal_name=firstName, animal_id=1}
So my question is:
How can I collect only animal_id from the array animalList > ?
Your animalList is an array list with HashMaps as its elements, so when you call animalList.get(position), it will return a HashMap. To retrieve an animal_id just use :
(animalList.get(position)).get(animal_id).toString();
you have to create a Modelclass/Pojo Class (Private variable and getters and setters) for Animals,
ArrayList<AnimalModel> animalsArrayList = new ArrayList<AnimalModel>();
add the Animals object/data to animalsArrayList and listview.setAdapter(animalsArrayList);
then
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// TODO Auto-generated method stub
Object object = speakerListView.getItemAtPosition(position);
AnimalModel animals_data = (AnimalModel) object;
id = animals_data.getAnimal_id()
// call delete Async with thid Id
}
});
You code looks pretty messy. If I were you I would create a Custom Adapter that extends the base adapter and takes as a parameter either a hashmap or a list that you pass in the constructor. There you can have different listeners. Also if you want to notify the activity you can have the "luxury" to pass an interface as a parameter and notify the activity when something changes.
Regarding the json part, I would create two new classes, one which is a Thread Manager that receives tasks and handles them further and another class where u make the http calls and the json parsing.
I have done a similar application that receives data from a nebula interface and displays them to the user.
I have made a custom progress Dialog,I wan to close it in my postExecute method,I have tried as below,But i don't know how to dismiss it.I have tried as below,Can anyone Please tell me how can i dismiss that custom dialog

Its easy try:
pDialog.dismiss();
STEP 1
Declare progress dialog above on create
private ProgressDialog pDialog;
STEP 2
Define preExecute method
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(context);
pDialog.setTitle("Please wait");
pDialog.setMessage("Processing...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
pDialog.setButton(DialogInterface.BUTTON_NEGATIVE, "Cancel", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
pDialog.show();
}
STEP 3
//Your back ground task as it is
STEP 4
ADD postExecute Method
protected void onPostExecute()
{
pDialog.dismiss();
}
You need to just call dismiss() method for ProgressDialog. Like
protected void onPostExecute(){
pDialog.dismiss();
}
You have the progressBar variable that holds a reference to the progress bar in your layout. To hide it, call
progressBar.setVisibility(View.GONE);
The RelativeLayout you're placing the ProgressBar in is unnecessary. Also consider including the ProgressBar statically in your layout and just setting its visibility to VISIBLE/GONE as necessary.
I have made an activity in that one ListView is ther,In that ListView each listItem is having an editText named "qty",which can be edited,one textView is there which displays "price",I need is when i edit the edittext and if the entered value is more than some limi the textView value will change,After that i have to pass them as a parameter to an api as below:
http://yehki.epagestore.in/app_api/updateCart.php?customer_id=41&product_id=30&quantity=90&product_id=23&quantity=90
from that i will get subtotal's of eact item and have to set them to each item in the list,can anyone please help me for it?My code is as below..Please help me save my life...thank you
