I am trying to display posts from a server in listView. So I used recycle-view to achieve that. Everything is working fine except that ll items are displaying twice.
I counted the total fetched items from server, and the count is 5, but adapter.getItemCount is showing 10.
After searching hours on the internet, I tried following :
#Override
public long getItemId(int position) {
return position;
}
#Override
public int getItemViewType(int position) {
return position;
}
and
homeFragmentAdapter.setHasStableIds(true);

After trying everything, I was still not able to resolve the issue. Any help/suggestions are welcome. Let me know If I left out any needed code--if so I can update it here.
`postListGlobal.add(postList);` below this line add ` homeFragmentAdapter.notifyDataSetChanged();` and remove ` homeFragmentAdapter.removeNull(); homeFragmentAdapter.addData(postListGlobal);homeFragmentAdapter.notifyDataSetChanged();` this code.Because in this case list added twice without notifying datasetchange check with your code by removing this.
postListGlobal.clear(); just clear tha arraylist before add .
postListGlobal.clear() before adding new list to the adapter.
And then notifyDataSetChanged() to let adapter know of the changes.

You can use a web view to render your google form within the application.
If for some reason you prefer not to use a web view, it is also possible to use the 'keys' in a google form(obtained via 'inspect element') to integrate the same with your application. Here is a link detailing the steps.
You can use the following in your onCreate():
progressDialog = new ProgressDialog(this);
progressDialog.setCancelable(false);
progressDialog.setMessage("Loading...");
queue = Volley.newRequestQueue(getApplicationContext());
submit.setOnClickListener(view -> {
postData(edit_name.getText().toString().trim(), edit_email.getText().toString().trim(),
edit_number.getText().toString().trim(), edit_remarks.getText().toString().trim());l
});
Also create a function in the activity as follows and in my Google Forms I have 4 entries to make which are name, phone, email and remark:
public void postData(final String name, final String email, final String phone, final String remark) {
progressDialog.show();
StringRequest request = new StringRequest(Request.Method.POST, Constants.url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.d("TAG", "Response: " + response);
if (response.length() > 0) {
Snackbar.make(btn_submit, "Successfully Posted", Snackbar.LENGTH_LONG).show();
finish();
} else {
Snackbar.make(btn_submit, "Try Again", Snackbar.LENGTH_LONG).show();
}
progressDialog.dismiss();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
progressDialog.dismiss();
Snackbar.make(btn_submit, "Error while Posting Data", Snackbar.LENGTH_LONG).show();
}
}) {
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<>();
params.put(Constants.nameField, name);
params.put(Constants.emailField, email);
params.put(Constants.phoneField,"+91"+phone);
params.put(Constants.remarkField, remark);
return params;
}
};
request.setRetryPolicy(new DefaultRetryPolicy(
50000,
DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
queue.add(request);
}
Create a Java class Constants where you enter the url and id of the entries in forms:
public class Constants {
// Google Forms URL .. replace with yours
public static final String url = "https://docs.google.com/forms/d/e/1FAIpQLSf65J3RmZS6QBg_TrsZZFx9s0l6109Q4E6PvUjuZ9go6D9l2g/formResponse";
// Google Form's Column ID
public static final String nameField = "entry.2006520554";
public static final String phoneField = "entry.1196974658";
public static final String emailField = "entry.1054781291";
public static final String remarkField = "entry.839339060"; }
Entry ids can be found by inspecting your Google Forms. For more details refer to the this link.
I need to look for the subject that matches the current time. For example, current time is 1:30. So if I'll run a query with Firebase, it should return the subject Math.
Here's my JSON where "2012123458" is a faculty_id.
schedule:{
"2012123458" : {
"Saturday" : {
"-K8j0EkwmWjj3vMqB2d3" : {
"classroom" : "Lab 3",
"subject" : "Science",
"time_end" : "2:00",
"time_start" : "0:00"
},
"asdasdasd" : {
"classroom" : "Lab 6",
"subject" : "PE",
"time_end" : "18:00",
"time_start" : "17:00"
},
"qweqweqweqwe" : {
"classroom" : "Lab 5",
"subject" : "PE",
"time_end" : "11:00",
"time_start" : "9:00"
}
}
}
}
I've tried this but returns a NullPointerException
gridView.setAdapter(listFaculty);
gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
FacultyList faculty = (FacultyList) parent.getItemAtPosition(position);
String faculty_id = faculty.getID();
//Display schedule in a Dialog box
final Dialog dialog = new Dialog(Faculty.this);
dialog.setContentView(R.layout.dialog_sched);

}
}
else {

}
}
}
#Override
public void onCancelled(FirebaseError firebaseError) {
Log.d("sched", firebaseError.getMessage());
}
});
dialog.show();
}
});
schedule class:
public class schedule {
private String subject;
private String time_end;
private String time_start;
public schedule(){ }
public schedule(String subject, String time_end, String time_start){
this.subject = subject;
this.time_end = time_end;

}
UPDATE:
The problem now is it does not work for some items on the grid view. It brings me back to my app's home screen after clicking on them. An empty dialog box appears for a short period then returns to the home screen.
I am working on an instant chat application.My problem is that when i am sending message through my chat application,Message is displayed two times instead of one.Screen shot is given below :
As you can see in the acreenshot that the message hiii is displayed two times but i have sent only once.

Message is stored in the Bean and Bean is added in the ArrayList .Now i am notifying my adapter that the ArrayList is updated using adapter.notifyDataSetChanged() method.But the problem is List view is displaying my sent message two times.Please help me to solve the issue .
My code gives correct response and sets transaction ID correctly. But on screen, the ID is missing the first time I submit, and when I go back and submit again, then the ID on screen is the ID of the first transaction.
On the first submit, this is rendered:
MOBILE NUMBER: 9129992929
OPERATOR: AIRTEL
AMOUNT: 344
TRANSACTION ID:
On the second submit, this is rendered:
MOBILE NUMBER: 9129992929
OPERATOR: AIRTEL
AMOUNT: 344
TRANSACTION ID: NUFEC37WD537K5K2P9WX
I want to see the second screen the first time I submit.
Response to the first submit:
D/TID IS: ====>NUFEC37WD537K5K2P9WX D/UID IS:
====>27W3NDW71XRUR83S7RN3 D/Response-------: ------>{"tid":"NUFEC37WD537K5K2P9WX","uid":"27W3NDW71XRUR83S7RN3","status":"ok"}

Because you have used Volley library which is already asynchronous, you don't have to use AsyncTask anymore.
Your code can be updated as the following (not inside AsyncTask, direct inside onCreate for example), pay attention to // update TextViews here...:
...
String url = "http://www.example.com/index.php";
RequestQueue requestQueue = Volley.newRequestQueue(this);
StringRequest postRequest = new StringRequest(Request.Method.POST, url,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
try {
JSONObject json_Response = new JSONObject(response);
String _TID = json_Response.getString("tid");
String _uid = json_Response.getString("uid");
String _status = json_Response.getString("status");
String tid_m =mytid.setTId_name(_TID);
Log.d("TID IS","====>"+tid_m);
Log.d("UID IS","====>"+_uid);
// update TextViews here...
txtTransId.setText(_TID);
txtStatus.setText(_status);
...
} catch (JSONException e) {
e.printStackTrace();
}
Log.d("Response-------", "------>" + response);
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e("Responce error==","===>"+error);
error.printStackTrace();
}
}
requestQueue.add(postRequest);
...
P/S: since the reponse data is a JSONObject, so I suggest you use JsonObjectRequest instead of StringRequest. You can read more at Google's documentation.
Hope it helps!
Your line of code should be executed after complete execution of network operation and control comes in onPostExecute(); of your AsyncTask.
confirm_tId.setText(_tid);
