At this point, I would like to update a db field at button click and reload PollActivity.java to force the RecyclerView update (I'd like that the NEW image disappear from the updated CardView). I guess to do this calling a method of my QueryUtils.java (one of the method it will contain), avoiding to write too mutch code inside adapter.
QueryUtils.java
#SuppressLint("Registered")
public class QueryUtils extends Application {
private String tag_string_req = "req_poll_answer_upg";
public void upgPollAnswer(final String UserId, final String PollId, final String AnswerId){

Log.d("NINJA", "Poll: " + PollId);
Log.d("NINJA", "Risposta: " + AnswerId);
StringRequest strReq = new StringRequest(Request.Method.POST, AppConfig.POLL_ANSWER_UPG, new Response.Listener<String>() {

boolean error = jObj.getBoolean("error");
String message = jObj.getString("message");
if (!error) {
Log.d("NINJA", "Messaggio: " + message);
PollActivity pollActivity = new PollActivity();
pollActivity.reloadActivity();
} else {
//myDialog.dismiss();
// Error in login. Get the error message
String errorMsg = jObj.getString("error_msg");
int idErrorRes = getResources().getIdentifier(errorMsg, "string", getPackageName());
String strErrorRes = getString(idErrorRes);
Log.d("NINJA", "ErrorePhP: " + strErrorRes);

}

};
// Adding request to request queue

}
At the end of the update procedure, I call the reloadActivity method in PollActivity, to reload itself. THIS call generate the error below:

I'm new in Android programming and I tried different solution found in this great forum, but none of them worked for me.
Please help me
Problem is that you are trying to create a new instance of activity without the use of intent :
PollActivity pollActivity = new PollActivity();
pollActivity.reloadActivity();
You should replace this code with the following lines:
public void onClickChangeActivity() {
Intent intent = new Intent(this, PollActivity.class);
startActivity(intent);
}
But your solution is far away from the ideal solutions available in the market. Restarting the activity whenever there is a change in data because you have to update data can never be a good way to go.
Try considering one of these ways to prevent activity restart
Create a data stream(list of data) and keep on reading that on
activity level.
Create a local broadcast receiver
Do let me know if you need help in above ways.
As a quick fix for the problem you can use this hackish way
Create a callback
interface Result {
void success(ResponseModel model);
void failure(Throwable throw);
}
In QueryUtils
List resultCallbacks = new ArrayList(); public void
addCallback(Result result) { resultCallbacks.add(result); }
create List resultCallbacks and a method addCallback to add the callbacks
In PollsActivity write this
((QueryApplication)getApplicationContext().getApplication()).addCallbacks(this);
and implement the callback.
On receiving any data update your list and do
RVUpdater.notifyDataSetChanged();
Hope this will help.

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 have a listView that is supposed to accept a shared message and image where the image is placed within the ImageView. This feature works for just the first message, but once an image is shared, each message received after that initial one becomes a copy of that same image even though the blank image placeholder was already set, which is just a one pixel black png:
holder.sharedSpecial.setImageResource(R.drawable.image_share_empty_holder);
An example is below:
The green textbox is the recipient. They have recieved a shared image from the yellow textbox. The yellow textbox then simply sends a normal message and I have set another image as a placeholder for normal messages: holder.sharedSpecial.setImageResource(R.drawable.image_share_empty_holder);
The same previously shared image takes precedence. I have used notifyDataSetChanged() so as to allow for the updating the adapter so that it would recognize not to use the same image, but to no avail.
How can I reformulate this class so that the image shared is only displayed with the proper message and not copied into each subsequent message?

I have gone through your code and this is common problem with listview that images starts repeating itself. In your case I think you have assigned image to Imageview every if and else if condition but if none of the condition satisfy it uses the previous image.
I would suggest to debug the getview method and put break points on the setImageResource. I use volley for these image loading and it has a method called defaultImage so that if no url is there the image is going to get the default one. So add that default case and see if it works.
If any of the above point is not clear feel free to comment.
I'm using the socialAuth plugin to connect a user to linkdin within my app. I have the connection set up correctly and retrieves data. However, I'm unsure how I can get my main activity to wait until the socialAuthListeners have fired and finished. I know a little about threading but I haven't used it with listeners before. Here's my code:
public class LinkdinAuth {
private static final String TAG = "TEST";
// SocialAuth Components
SocialAuthAdapter adapter;
ProgressDialog mDialog;
private Context context;
private boolean loggedIn = false;
private Bundle LinkdinData;
public LinkdinAuth(Context C){
this.context = C;
LinkdinData = new Bundle();
adapter = new SocialAuthAdapter(new ResponseListener());
}
public void adapterAuthorize(View v){
adapter.authorize(v.getContext(), Provider.LINKEDIN);
}
private final class ResponseListener implements DialogListener
{
public void onComplete(Bundle values) {
String providerName = values.getString(SocialAuthAdapter.PROVIDER);
Log.d("Main", "providername = " + providerName);
mDialog = new ProgressDialog(context);
mDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
mDialog.setMessage("Loading...");
//Get profile information
adapter.getUserProfileAsync(new ProfileDataListener());
// get Job and Education information
mDialog.show();
adapter.getCareerAsync(new CareerListener());
loggedIn = true;
Log.d("Main", "LOGGED IN = " + loggedIn );
Toast.makeText(context, providerName + " connected", Toast.LENGTH_SHORT).show();
}
#Override
public void onBack() {
Log.d("Main", "Dialog Closed by pressing Back Key");
}
#Override
public void onCancel() {
Log.d("Main", "Cancelled");
}
#Override
public void onError(SocialAuthError e) {
Log.d("Main", "Error");
e.printStackTrace();
}
}
// To receive the profile response after authentication
private final class ProfileDataListener implements SocialAuthListener<Profile> {
#Override
public void onExecute(String provider, Profile t) {
Log.d("Sign Up", "Receiving Data");
mDialog.dismiss();
Profile profileMap = t;
LinkdinData.putString("Validated ID", profileMap.getValidatedId() );
LinkdinData.putString("First Name", profileMap.getFirstName());
LinkdinData.putString("Last Name", profileMap.getLastName());
LinkdinData.putString("Email", profileMap.getEmail());
LinkdinData.putString("Country", profileMap.getCountry());
LinkdinData.putString("Language", profileMap.getLanguage());
LinkdinData.putString("Location", profileMap.getLocation());
LinkdinData.putString("Profile Image URL", profileMap.getProfileImageURL());
}
#Override
public void onError(SocialAuthError arg0) {
// TODO Auto-generated method stub
}
}
private final class CareerListener implements SocialAuthListener<Career> {
#Override
public void onExecute(String provider, Career t) {
Log.d("Custom-UI", "Receiving Data");
mDialog.dismiss();
Career careerMap = t;
//get education
Log.d("Main", "Education:");
if(careerMap.getEducations() != null){
for(Education E: careerMap.getEducations()){
Log.d("Main", "School = " +E.getSchoolName() );
Log.d("Main", "Major = " + E.getFieldOfStudy() );
Log.d("Main", "Degree = " + E.getDegree() );
Log.d("Main", "Start Date = " + E.getStartDate() );
Log.d("Main", "End Date = " + E.getEndDate() );
}
}
Log.d("SignUp", "Career");
if(careerMap.getPositions() != null){
for(Position P: careerMap.getPositions()){
LinkdinData.putString("Company Name", P.getCompanyName() );
LinkdinData.putString("Job Title", P.getTitle() );
Log.d("Main", "Industry = " + P.getIndustry() );
Log.d("Main", "Start Date = " + P.getStartDate() );
Log.d("Main", "End Date = " + P.getEndDate() );
}
}
}
#Override
public void onError(SocialAuthError e) {
}
}
public boolean isLoggedIn(){
return loggedIn;
}
public Bundle getLinkdinData(){
return LinkdinData;
}
So, as you can see. I have 2 listeners that get data after authorization goes through. And my main activity makes creates an instance, calls the adapterAuthroizeMethod and then if the user logs in a flag is set. Then getLinkedData is called. However I would like it to wait until I know the listeners have fired before calling getlinkdinData. Here's what my Main Activity does after a button press:
L.adapterAuthorize(v);
loggedInWithLinkdin = L.isLoggedIn();
Bundle B = L.getLinkdinData();
Intent i = new Intent(getBaseContext(), UserRegistration.class);
i.putExtra("linkdin bundle", B);
//startActivity(i);
Any ideas?
thanks
Well, not a recommend solution but more of a hack.
Here is what you can do.
Wrap the aync call around this construct :
AtomicBoolean done = new AtomicBoolean(false);
Global ans; // the return value holder
try{
result = someAsyncCall(query, new Thread()); // this new thread is for listener callback
result.setResultListener(result -> {
// do something with result.
ans = result.getAns() ; // set global ans
done.set(true);
synchronized (done) {
done.notifyAll(); // notify the main thread which is waiting
}
});
}
catch (Exception e ) {
Log(e);
}
synchronized (done) {
while (done.get() == false) {
done.wait(); // wait here until the listener fires
}
}
return ans; // return global ans
