Develop Reference

Error in getting value from textviews in getIntent.getParcelableExtra

I was working with android project these days, and It will finish soon, but I got stuck in my project. First, I want to create search activity which will be used for searching movies. The searching activity runs well, but whenever it comes to adding the selected movie, it shown me the error code below:
java.lang.NullPointerException: Attempt to invoke virtual method 'void com.example.idstream.pojo.Movies.setTitle(java.lang.String)' on a null object reference
at com.example.idstream.search.MoviesDetailActivity.addFavorite(MoviesDetailActivity.java:96)
at com.example.idstream.search.MoviesDetailActivity.access$100(MoviesDetailActivity.java:19)
at com.example.idstream.search.MoviesDetailActivity$1.onClick(MoviesDetailActivity.java:78)
This code has an error in this area:
Movies movies = getIntent().getParcelableExtra(EXTRA_TITLE);
movies.setTitle(getIntent().getStringExtra(EXTRA_TITLE));
movies.setRelease_info(getIntent().getStringExtra(EXTRA_RELEASE));
movies.setLanguage(getIntent().getStringExtra(EXTRA_LANGUAGE));
movies.setDescription(getIntent().getStringExtra(EXTRA_OVERVIEW));
movies.setPhotos(getIntent().getStringExtra(EXTRA_PHOTOS));
I've tried to add the selected movie to database in other activity, but it didn't mention any error. But when I tried to save the selected movie to database, it turns out an error. I also tried to send it to a toast, which I wanna make sure whether the value that I sent was successfully retrieved. The toast is successfully get the data.
Here is my SearchFragment.java:
public class SearchMovieFragment extends Fragment implements LoaderManager.LoaderCallbacks<ArrayList<Movies>> {

movies.setDescription(getIntent().getStringExtra(EXTRA_OVERVIEW));
movies.setPhotos(getIntent().getStringExtra(EXTRA_PHOTOS));
movieHelper.deleteMovie(getIntent().getStringExtra(EXTRA_MOVIE));
}
}
And this one is my MovieHelper.java:
public Boolean getOne(String name){
String querySingleRecord = "SELECT * FROM " + DATABASE_TABLE + " WHERE " +DatabaseContract.MovieColoumn.TITLE+ " " + " LIKE " +"'"+name+"'" ;
Cursor cursor = database.rawQuery(querySingleRecord,null);
cursor.moveToFirst();
Log.d("cursor", String.valueOf(cursor.getCount()));
if (cursor.getCount() > 0 ){
return true;
}else if(cursor.getCount() == 0){
return false;
}
return false;
}
public long insertMovie(Movies mMovies){
ContentValues args = new ContentValues();
args.put(IDS,mMovies.getId());
args.put(DatabaseContract.MovieColoumn.TITLE,mMovies.getTitle());
args.put(DatabaseContract.MovieColoumn.RELEASE_INFO,mMovies.getRelease_info());
args.put(DatabaseContract.MovieColoumn.LANGUAGE,mMovies.getLanguage());
args.put(DatabaseContract.MovieColoumn.DESCRIPTION,mMovies.getDescription());
args.put(DatabaseContract.MovieColoumn.PHOTOS,mMovies.getPhotos());
return database.insert(DATABASE_TABLE,null,args);
}

I believe the problem is here:
Movies movies = getIntent().getParcelableExtra(EXTRA_TITLE);
movies.setTitle(getIntent().getStringExtra(EXTRA_TITLE));
Notice that you're using the same EXTRA_TITLE for both.
I think that what's happening is that getParcelableExtra() is returning null, because the implementation of Bundle (the extras) will catch the ClassCastException:
// ...
try {
return (T) o;
} catch (ClassCastException e) {
typeWarning(key, o, "Parcelable", e);
return null;
}
And then you get a NullPointerException when you try to call setTitle().
Instead, create a new Movies instance yourself:
Movies movies = new Movies();
movies.setTitle(getIntent().getStringExtra(EXTRA_TITLE));
Alternatively, you could implement the Parcelable interface in your Movies class, and then you wouldn't have to bother adding all of its fields one by one.

Get data from Search result(in a fragment) and update (other)fragments in the tab layout

I have an Android Activity which has a tab-layout(with four fragments), and first fragment have a search function which search the data through a backend service. When it's success in getting data, then it should update other fragments with relevant data(recycler views and text views). But i cannot get an idea of how to work this thing around. I'll provide what i have done so far, let me know what am i doing wrong and how should i progress. A Code example is more than welcome.
What i have tried so far is within my search fragment, when the search function retrieves success data it will show a list item first of the users profile data. When on click on that item the whole activity will restart and the data is being binded to all the other fragments. What i need to achieve now is without refreshing nor restarting the whole activity, pass the data to relevant fragments and update the views.
Collection Activity is the holder activity for my four fragments of the tab layout

getTag, setTag checkbox issue, how can I get my activity to post checked boxes? The other values are posting ok

I am in the process of changing someone else's code from listView to recyclerView, changing code in my activity and my adapter where required - the adapter is a big change, with OnCreateView, onBindViewHolder and so on...
As the question indicates, category, name, phone, address, comment, public_or_private are posting successfully to mySql db, but nothing for checkedContacts. I'd be very grateful if you could tell me how to fix the problem.
I am quite sure it has to do with something around this line:
//get the other data related to the selected contact - name and number
SelectPhoneContact contact = (SelectPhoneContact) checkbox.getTag();
I am not getting any errors but when I run in debug mode it gets to here and then jumps to:
} catch (Exception e) {
System.out.println("there's a problem here unfortunately");
e.printStackTrace();
}
I think it has something to do with setTag but I find it confusing and I'm not sure where it should be set (if, even, that is the problem).
I'm posting the relevant code for my activity, NewContact and the RecyclerViewAdapter, PopulistoCOntactsAdapter. Thanks for any help.

Clear ListView if response is a empty array?

I have two spinners the first one for month and the second for years.I am trying to call a method send_date() if on Item Selected is called for any of the 2 spinners.
So I have two problems:- 1)send_date() gets called twice the first
time it gets the correct data as expected but the 2nd time it returns
a empty array. 2)When I select another month or year the old data does
not get removed that is the list does not refresh.
The following is my code for on Item Selected :-
public void onItemSelected(AdapterView<?> parent, View view, int position, long id)
{
int i = spinYear.getSelectedItemPosition();
selected_year = years.get(i);
Log.d("Selection Year",selected_year);
tv_year.setText(selected_year);
try {
send_date();
} catch (JSONException e) {
e.printStackTrace();
}
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
And for the month spinner:-
public void onItemSelected(AdapterView<?> parent, View view, int position, long id)
{
int j = spinMonths.getSelectedItemPosition();
selected_month = Months[j];
Date date = null;
try {
date = new SimpleDateFormat("MMMM").parse(selected_month);
} catch (ParseException e) {
e.printStackTrace();
}
Calendar cal = Calendar.getInstance();
cal.setTime(date);
tv_month.setText(String.valueOf(cal.get(Calendar.MONTH)+1));
Log.d("Selection Month",selected_month);
try {
send_date();
} catch (JSONException e) {
e.printStackTrace();
}
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
On response I call the following method for populating the list view with data:-
public void showBS(String response)
{
ParseBS_all pb = new ParseBS_all(response);
pb.parseBS();
bl = new BS_allList(getActivity(),ParseBS_all.doc_no,ParseBS_all.balance,ParseBS_all.total,ParseBS_all.vat,ParseBS_all.profit);
lv_bsall.setAdapter(bl);
}
This is the code for the send_date method:-
//This method is used to send month and year
private void send_date() throws JSONException {
final String year = tv_year.getText().toString();
final String month = tv_month.getText().toString();
StringRequest stringRequest = new StringRequest(Request.Method.POST, SEND_DATE,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
//display.setText("This is the Response : " + response);
String resp = response.toString().trim();
if (resp.equals("Nothing to display"))
{
Toast.makeText(getContext(), "Nothing to Display", Toast.LENGTH_SHORT).show();
// bl.clear();
lv_bsall.setAdapter(bl);
bl.notifyDataSetChanged();
}else
{
Toast.makeText(getContext(), "Response" + response, Toast.LENGTH_LONG).show();
Log.d("RESPONSE for date", response.toString().trim());
showBS(response);
}
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
}) {
#Override
protected Map<String, String> getParams() throws AuthFailureError {
GlobalClass gvar = (GlobalClass) getActivity().getApplicationContext();
String dbname = gvar.getDbname();
Map<String, String> params = new HashMap<>();
params.put(KEY_DBNAME, dbname);
params.put(KEY_MONTH, month);
params.put(KEY_YEAR,year);
return params;
}
};
RequestQueue requestQ = Volley.newRequestQueue(getContext());
requestQ.add(stringRequest);
}
Adapter code for list view.
public class BS_allList extends ArrayAdapter<String>
{
private String[] doc_no;
private String[] balance;
private String[] total;
private String[] vat;
private String[] profit;
private Activity context;
public BS_allList(Activity context, String[] doc_no, String[]balance, String[] total, String[] vat, String[] profit)
{
super(context, R.layout.bs_list_all, doc_no);
this.context =context;
this.doc_no= doc_no;
this.balance = balance;
this.total = total;
this.vat=vat;
this.profit = profit;
}
#Override
public View getView(int position, View listViewItem, ViewGroup parent)
{
if (null == listViewItem)
{
LayoutInflater inflater = context.getLayoutInflater();
listViewItem = inflater.inflate(R.layout.bs_list_all, null, true);
}
TextView tv_docNo = (TextView) listViewItem.findViewById(R.id.tvdoc_no);
TextView tv_balance = (TextView) listViewItem.findViewById(R.id.tv_balance);
TextView tv_tot = (TextView) listViewItem.findViewById(R.id.tv_total);
TextView tv_vat = (TextView) listViewItem.findViewById(R.id.tv_vat);
TextView tv_pf = (TextView) listViewItem.findViewById(R.id.tv_profit);
tv_docNo.setText(doc_no[position]);
tv_balance.setText(balance[position]);
tv_tot.setText(total[position]);
tv_vat.setText(vat[position]);
tv_pf.setText(profit[position]);
return listViewItem;
}
}
Also note that I have set the spinner to point to the current month and year so the first time it works properly.
I am new to programming so any help or suggestion is appreciated.Thank you.

Hi #AndroidNewBee,
As per our discussion made following changes in your code and you will get proper output and it will resolve your issues.
if (resp.equals("Nothing to display"))
{
Toast.makeText(getContext(), "Nothing to Display", Toast.LENGTH_SHORT).show();
bl = new BS_allList(getActivity(),{""},{""},{""},{""},{""});
lv_bsall.setAdapter(bl);
}
And second is check validation as below,
try {
if((selected_year != null & selected_year.length > 0 ) & (tv_month.getText().toString() != null & tv_month.getText().toString().length > 0))
{
send_date();
}
} catch (JSONException e) {
e.printStackTrace();
}

First you shouldn't be using so many String[], instead wrap them in a class
Class BSDataModel{
private String doc_no;
private String balance;
private String total;
private String vat;
private String profit;
//getters and setters
}
Now the reponse result should be added as in ,it returns List<BSDataModel>
List<BSDataModel> reponseList = new ArrayList<>();
//for example adding single response
for(int i=0;i<jsonArrayResponse.length();i++){
BSDataModel singleResponse = new BSDataModel();
singleResponse.setDocNo(jsonArrayResponse.get(i).getString("doc_no"));
singleResponse.setBalace(jsonArrayResponse.get(i).getString("balance"));
//etc..finall add that single response to responseList
reponseList.add(singleResponse);
}
BS_allList.java
public class BS_allList extends ArrayAdapter<BSDataModel>
{
private List<BSDataModel> bsList;
private Activity context;
public BS_allList(Activity context,List<BSDataModel> bsList)
{
super(context, R.layout.bs_list_all, bsList);
this.context =context;
this.bsList = bsList;
}
#Override
public View getView(int position, View listViewItem, ViewGroup parent)
{
if (null == listViewItem)
{
LayoutInflater inflater = context.getLayoutInflater();
listViewItem = inflater.inflate(R.layout.bs_list_all, null, true);
}
TextView tv_docNo = (TextView) listViewItem.findViewById(R.id.tvdoc_no);
TextView tv_balance = (TextView) listViewItem.findViewById(R.id.tv_balance);
TextView tv_tot = (TextView) listViewItem.findViewById(R.id.tv_total);
TextView tv_vat = (TextView) listViewItem.findViewById(R.id.tv_vat);
TextView tv_pf = (TextView) listViewItem.findViewById(R.id.tv_profit);
BSDataModel bsData = bsList.get(position);
tv_docNo.setText(bsData.getDoc());
tv_balance.setText(bsData.getBalance());
tv_tot.setText(bsData.getTot());
tv_vat.setText(bsData.getVat());
tv_pf.setText(bsData.getPF());
return listViewItem;
}
}
Now in your class
BS_allList bl = new BS_allList(getActivity(),responseList);//which you got above
After receiving new Response
// remove old data
responseList.clear(); // list items in the sense list of array used to populate listview
if(newresponseArray.size() > 0){
for(int i=0;i<newjsonArrayResponse.length();i++){
BSDataModel singleResponse = new BSDataModel();
singleResponse.setDocNo(newjsonArrayResponse.get(i).getString("doc_no"));
singleResponse.setBalace(newjsonArrayResponse.get(i).getString("balance"));
//etc..finall add that single response to responseList
reponseList.add(singleResponse);
}
}
//refresh listview
bl.notifyDataSetChanged();

Try this way,
1. adapter.clear();
2. Add/Remove your list Items.
3. listview.setAdapter(adapter);
4. adapter.notifyDatasetChanged();
this procedure should work.

How to make dynamic API calls depending on user preferences?

I am using theMovieDb.com API to fetch data.On launching the app it shows grid view of popular movies. In setting menu, it has option to sort the grid view on the basis of more popular and highest rated. I am using shared preferences to store user preferences and a listener on preference change.But unable to sort the grid view.
