Updating code to save the state of the clicked items

I'm a new developer to android development. I'll like the code below (for querying and displaying images media collection) whose images checkboxes are checked when clicked, to be updated to include onsaveinstancestate to save the state of the clicked/checked items.
public class PhotosFragment extends Fragment {
ArrayList<ImageModel > imageList;
RecyclerView imageRecyclerView;
ImageAdapter imageAdapter;
View view;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
view = inflater.inflate(R.layout.fragment_photos, container, false);
runtimePermission();
return view;
}
private void runtimePermission() {
Dexter.withContext(getContext()).withPermission(Manifest.permission.READ_EXTERNAL_STORAGE)
.withListener(new PermissionListener() {
#Override
public void onPermissionGranted(PermissionGrantedResponse permissionGrantedResponse) {
init();
getAllImages();
setImageList();
}
#Override
public void onPermissionDenied(PermissionDeniedResponse permissionDeniedResponse) {
Toast.makeText(getContext(), "Permission is Required!", Toast.LENGTH_SHORT).show();
}
#Override
public void onPermissionRationaleShouldBeShown(PermissionRequest permissionRequest, PermissionToken permissionToken) {
permissionToken.continuePermissionRequest();
}
}).check();
}
public void init() {
imageRecyclerView = (RecyclerView) view.findViewById(R.id.photos_recycler);
imageList = new ArrayList<>();
}
public void setImageList() {
imageRecyclerView.setLayoutManager((new GridLayoutManager(getContext(), 4)));
imageAdapter = new ImageAdapter(getContext(), imageList);
imageRecyclerView.setAdapter(imageAdapter);
/* Here `isSelected` is a boolean variable. It is true when item is checked and false when not checked. When false, the if condition evaluates to true and the `selectImage()` method is called, otherwise the `unSelectImage()` is called */
imageAdapter.setOnItemClickListener(new ImageAdapter.OnItemClickListener() {
#Override
public void onItemViewClick(int position, View v){
try {
if (!imageList.get(position).isSelected) {
selectImage(position);
} else {
unSelectImage(position);
}
} catch (ArrayIndexOutOfBoundsException ed) {
ed.printStackTrace();
}
}
});
};
public void selectImage(int position) {
imageList.get(position).setSelected(true);
imageAdapter.notifyDataSetChanged();
}
public void unSelectImage(int position) {
imageList.get(position).setSelected(false);
imageAdapter.notifyDataSetChanged();
}
}
Querying the mediastore for images collection
public void getAllImages() {
Uri imageCollection;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
imageCollection = MediaStore.Images.Media.getContentUri(MediaStore.VOLUME_EXTERNAL);
} else {
imageCollection = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;
}
String[] projection = new String[] {
MediaStore.Images.Media._ID,
MediaStore.Images.Media.DISPLAY_NAME,
MediaStore.Images.Media.DATE_ADDED,
MediaStore.Images.Media.SIZE
};
String sortOrder = MediaStore.Images.Media.DATE_ADDED + " DESC";
Cursor cursor = getActivity().getContentResolver().query(imageCollection , projection, null, null, sortOrder);
int idColumn = cursor.getColumnIndexOrThrow(MediaStore.Images.Media._ID);
int nameColumn = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DISPLAY_NAME);
int dateColumn = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATE_ADDED);
int sizeColumn = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.SIZE);
while (cursor.moveToNext()) {
long id = cursor.getLong(idColumn);
String name = cursor.getString(nameColumn);
int duration = cursor.getInt(dateColumn);
int size = cursor.getInt(sizeColumn);
Uri uriImage = Uri.withAppendedPath(imageCollection, ""+ id);
ImageModel imageModel = new ImageModel();
imageModel.setImage(uriImage);
imageList.add(imageModel);
}
cursor.close();
}

How to show spinner selection in gridview?

i am having spinner with country name and below i am showing flags according to country spinner.here i want to show flag according to spinner selection and not all..how can i show that in gridView?
HERE IS MY CODE:
public class FanciersFragment extends Fragment {
private View rootView;
private Spinner spFindCountry;
private RecyclerView rvFanciers;
private ArrayList<CountryDetail> countryDetailArray;
private LinearLayout llContainer;
private String countryCode;
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
rootView = inflater.inflate(R.layout.fragment_fanciers, container, false);
iitializeView();
return rootView;
}
private void iitializeView() {
spFindCountry = (Spinner) rootView.findViewById(R.id.sp_country_find);
rvFanciers = (RecyclerView) rootView.findViewById(R.id.rv_fanc_items);
llContainer = (LinearLayout) rootView.findViewById(R.id.ll_fanciers_container);
GridLayoutManager gridLayoutManager = new GridLayoutManager(getActivity() , 3);
rvFanciers.setHasFixedSize(true);
rvFanciers.setLayoutManager(gridLayoutManager);
getCounties();
}
#Override
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
getActivity().setTitle("FanciersResponse");
}
private void getCounties() {
if(Utility.isNetworkConnected(getActivity())) {
final Call<Countries> resp = Utility.getApiService().getContries();
resp.enqueue(new Callback<Countries>() {
#Override
public void onResponse(Call<Countries> call, Response<Countries> response) {
if (response.code() == 200) {
Countries countries = (Countries) response.body();
if (countries != null)
if (countries.getStatus() != null)
if (countries.getStatus().equals("OK")) {
countryDetailArray = (ArrayList<CountryDetail>) countries.getCountryDetails();
if(countryDetailArray != null)
populateCountrySpinner(countryDetailArray);
pupulateFanciers();
} else {

}
}
#Override

}
});
}
else {
Utility.ShowSnackBar(getResources().getString(R.string.no_internet), llContainer);
}
}
private void pupulateFanciers() {
Fanciers rcAdapter = new Fanciers(getActivity(), countryDetailArray , new Fanciers.OnItemClickListener() {
#Override
public void onItemClick(CountryDetail item) {
if(item != null){
Bundle b = new Bundle();
b.putSerializable(Constants.COUNTRY_DETAILS , item);
Intent intent = new Intent(getActivity() , CountryBaseFanciers.class);
intent.putExtra(Constants.BUNDLE , b);
startActivity(intent);
}
}
});
rvFanciers.setAdapter(rcAdapter);
}
private void populateCountrySpinner(final ArrayList<CountryDetail> countryDetailList) {
ArrayList<String> countryList = new ArrayList<>();
if(countryDetailList != null){
for(CountryDetail countryDetail: countryDetailList ){
countryList.add(countryDetail.getCountryName());
}
}
/*adapterCountry = new ArrayAdapter<String>(getActivity(), R.layout.spinner_layout, R.id.tv_country_name, countryList);
spCountry.setAdapter(adapterCountry);*/
HintSpinner<String> hintSpinner = new HintSpinner<>(
spFindCountry,
// Default layout - You don't need to pass in any layout id, just your hint text and
// your list data
new HintAdapter<>(getActivity(), getResources().getString(R.string.find_country), countryList),
new HintSpinner.Callback<String>() {
#Override
public void onItemSelected(int position, String itemAtPosition) {
// Here you handle the on item selected event (this skips the hint selected event)
countryCode = countryDetailList.get(position).getCountryCode();
}
});
hintSpinner.init();
}
}
I am getting all flags in gridview but i want on selection of spinner..kindly help

Instead of using GridView, try extending an ArrayAdapter class to use images, setting it in a ListView and implementing a filter based on country name. This should be fine if you want only one flag to be displayed at a time.

Add data in SQLite Database using Fragment in Android

I am trying to Add data in SQLite Database using Fragment, but it's not Adding in Database and there is no error while running app.
My code in AddRoom Fragment :
public class AddRoom extends Fragment implements View.OnClickListener {
DatabaseHotel myHotel;
Button bt_addRoom;
EditText ed_roomtype, ed_roomPrice, ed_noOfRoom;
View view;
Context context;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
myHotel = new DatabaseHotel(getActivity());
view = inflater.inflate(R.layout.addroom, container, false);
bt_addRoom = (Button)view.findViewById(R.id.bt_addroom);
ed_roomtype = (EditText)view.findViewById(R.id.ed_roomtype);
ed_roomPrice = (EditText)view.findViewById(R.id.ed_roomprice);
ed_noOfRoom = (EditText)view.findViewById(R.id.ed_noofrooms);
return view;
}
#Override
public void onClick(View v) {
bt_addRoom.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
addRoom();
}
});
}
private void addRoom(){
String roomType = ed_roomtype.getText().toString();
int roomPrice = Integer.parseInt(ed_roomPrice.getText().toString());
int noOfRoom = Integer.parseInt(ed_noOfRoom.getText().toString());
boolean inserted = myHotel.addRoom(roomType, roomPrice, noOfRoom);
if (inserted){
Message.message(context, "Room Added Succeccfully");
}else {
Message.message(context, "Room Not Added!!");
}
}
}
In My Database class : addRoom() method code:
public boolean addRoom(String roomType, int roomPrice, int numberOfRoom){
SQLiteDatabase db = mydb.getReadableDatabase();
ContentValues cv = new ContentValues();
cv.put(Database.ROOM_TYPE, roomType);
cv.put(Database.ROOM_PRICE, roomPrice);
cv.put(Database.NUMBER_OF_ROOMS, numberOfRoom);
try {
long result = db.insert(Database.ROOM_TABLE,null, cv);
if (result == -1){
return false;
}else {
return true;
}
}catch (SQLException e){
Message.message(context, e+"");
}
return true;
}

I think you missed
bt_addRoom.setOnClickListener(this);
in onCreateView(..). You should register OnClickListener first.

What MD said... but you might also want mydb.getWriteableDatabase(); and not getReadableDatabase() as well

Is it possible to send an object from a fragment to another fragment?

The object that I want to send from a fragment to another fragment is "post".
The DemandFragment consist of a listview which consist of items which are post objects.
I need to send the selected item from the listview, in this case postArrayList.get(position), to SelectedPostFragment.
I've tried with bundle but this is not working...
Does someone know how to fix this?
DemandFragment:

I believe your Post class needs to implement Parcelable as well to pass it in a bundle between fragments with putParcelable().
Check out: Parcelable.
This is also a great example.
Basic implementation:
public class Post extends ParseObject implements Serializable, Parcelable {
...
public int describeContents() {
return 0;
}
public void writeToParcel(Parcel out, int flags) {
out.writeString(getId());
out.writeSring(getUsername());
...
}
public static final Parcelable.Creator<Post> CREATOR
= new Parcelable.Creator<Post>() {
public Post createFromParcel(Parcel in) {
return new Post(in);
}
public Post[] newArray(int size) {
return new Post[size];
}
};
private Post(Parcel in) {
// Items must be read in the order they were written.
setId(in.readString());
setUsername(in.readString());
...
}
}
Try that on for size, hope it helps.

Use the activity as a transporting mechanism.
Create an interface for the activity to implement, which the activity passes to the fragment upon instantiation. Whenever you want to transfer data, call the callback for the interface. Co-ordinate with the activity which fragment it needs to interact with and then post your data in another callback that will be linked to the fragment.
If all of this is too complex, then just use Otto and enjoy sending events everywhere without having to worry about detaching/attaching interfaces/listeners upon configuration change.

Accessing a Loader created in one fragment from another fragment

I have an app with a fairly standard fragment layout. An expandable listview fragment on the left and a panel on the right that is used for different things depending on what the user chooses to do with the list on the left (displaying data, adding new data, etc).
I'm using the LoaderManager (first time using loaders) with CommonWare's loaderex library as I have no need or desire to create a Content Provider for my database just so I can use a standard CursorLoader. This setup works great for displaying my list.
The issue I am having is when I use the second fragment to add data to the database. I cannot figure out how to trigger a re-load of the list in the first fragment. For the life of me I cannot figure out how to grab the loader from the first fragment in the second so that it will be aware that the data needs to be pulled again, nor can I seem to figure how to manually trigger a re-load.
As this is my first attempt at using Loaders, if I'm doing something improperly I'd be happy to be (gently) re-directed down a better path.

With a regular CursorLoader, this would happen automagically via the ContentObserver framework, which eventually boils down to a bunch of static data members.
With SQLiteCursorLoader, ContentObserver is not available, with the closest simulacrum being to route your CRUD operations through the Loader so it knows to reload the Cursor. And that is really only designed for use within a single activity.
So, as Luksprog suggested, your best option is to delegate CRUD work to the containing activity.
If these fragments might be hosted by disparate activities (e.g., for small/normal vs. large/xlarge screen sizes), define a common interface for handling this work, and have the fragments delegate to the interface.
