Data in RecycleCiew from Sql database only updates after i restart the app

I am making a feature for my app where the user can add a new food item inside RecyleView. But instead using a new activity I opted out for a popup that appears in the Main Activity where you can enter the food and the price which means the activity doesn't refresh. How can I display the items in the RecycleView without restarting the app?
Code in Main Activity:
public class SecondScreen extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.second_screen);
myDB = new MyDataBaseHelper(SecondScreen.this);
foodID = new ArrayList<>();
foodName = new ArrayList<>();
foodPrice = new ArrayList<>();
popUp();
//Data from Sql Tables
storeDataInArrays();
customAdapater = new CustomAdapater(SecondScreen.this, foodID, foodName, foodPrice);
recyclerView.setLayoutManager(new LinearLayoutManager(SecondScreen.this));
recyclerView.setAdapter(customAdapater);
//Storing the data from the sql table
public void storeDataInArrays(){
Cursor cursor = myDB.readAllData();
//Gets the count of the rows
if(cursor.getCount() == 0){
Toast.makeText(this, "No data", Toast.LENGTH_SHORT).show();
}else{
while(cursor.moveToNext()){
foodID.add(cursor.getString(0));
foodName.add(cursor.getString(1));
foodPrice.add(cursor.getString(2));
}
}
}
}
public void PopUP(){
btnAddFood.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
MyDataBaseHelper myDB = new MyDataBaseHelper(SecondScreen.this);
myDB.addFood(edtFoodName.getText().toString().trim(),
edtFoodPrice.getText().toString().trim());
//Dismisses the popUp after button click
myDialog.dismiss();
}
});
}
}
Code for RecycleView Adapter
public class CustomAdapater extends RecyclerView.Adapter<CustomAdapater.MyViewHolder> {
Context context;
private ArrayList foodID, foodName, foodPrice;
CheckBox chkItem;
//Constructor
CustomAdapater(Context context, ArrayList foodID, ArrayList foodName, ArrayList foodPrice){
//Declares to global variables that can be used in the MainAcivity
this.context = context;
this.foodID = foodID;
this.foodName = foodName;
this.foodPrice = foodPrice;
}
#NonNull
#Override
public CustomAdapater.MyViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
//Inflates the item_row layout
LayoutInflater inflater = LayoutInflater.from(context);
View view = inflater.inflate(R.layout.item_row, parent, false);
return new MyViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull CustomAdapater.MyViewHolder holder, int position) {
holder.checkItem.setText(String.valueOf(foodName.get(position)));
holder.foodPrice_txt.setText(String.valueOf(foodPrice.get(position) + "$"));
}
#Override
public int getItemCount() {
return foodID.size();
}
public class MyViewHolder extends RecyclerView.ViewHolder {
TextView foodPrice_txt;
CheckBox checkItem;
public MyViewHolder(#NonNull View itemView) {
super(itemView);
checkItem = itemView.findViewById(R.id.chkItemRow);
foodPrice_txt = itemView.findViewById(R.id.txtPriceRow);
}
}
}

Call notifyItemInserted after adding the item to your database and array lists, to update your adapter.
Like so:
String foodName = edtFoodName.getText().toString().trim();
String foodPrice = edtFoodPrice.getText().toString().trim();
myDB.addFood(foodName, foodPrice);
foodNames.add(foodName);
foodPrices.add(foodPrice);
customAdapater.notifyItemInserted(foodNames.size() - 1);

Custom Card View Adapter : notify data set changed not working

Im setting up a custom card-view slider adapter and on startup the card view loads up fine but after items is added/replaced in the array list and the notify adapter method is called, no changes occur to the content.
I have already tried adding the items directly from the adapter via a public method and the item gets added however, it is always placed at the last position.
This is my adapter :
static class UploadImageAdapter extends CardSliderAdapter<ImageObject>
{
private Context context;
private ArrayList<ImageObject> arrayList;
private OnUploadButtonClick onUploadButtonClick;
public interface OnUploadButtonClick{
void upload(int position);
}
UploadImageAdapter(Context context, ArrayList<ImageObject> items) {
super(items);
this.context = context;
this.arrayList = items;
}
static class ViewHolder{
ImageView image;
ImageButton addImage;
Button removeImage;
View layout;
}
#Override
public void bindView(int position, #NotNull View itemContentView, ImageObject imageObject) {
final ViewHolder holder = new ViewHolder();
holder.image = itemContentView.findViewById(R.id.card_image);
holder.addImage = itemContentView.findViewById(R.id.upload_image_btn);
holder.removeImage = itemContentView.findViewById(R.id.card_remove_btn);
holder.layout = itemContentView.findViewById(R.id.card_image_layout);
if (imageObject.hasImage) {
Glide.with(context)
.load(Uri.parse(imageObject.getImage_path()))
.placeholder(R.color.offsetWhiteBackground)
.centerCrop()
.transition(withCrossFade())
.into(holder.image);
holder.addImage.setVisibility(View.GONE);
holder.layout.setVisibility(View.VISIBLE);
holder.removeImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
}
else {
holder.layout.setVisibility(View.GONE);
holder.addImage.setVisibility(View.VISIBLE);
holder.addImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
onUploadButtonClick.upload(position);
}
});
}
}
#Override
public ImageObject getItem(int position) {
return arrayList.get(position);
}
void setOnUploadButtonClick(OnUploadButtonClick onUploadButtonClick){
this.onUploadButtonClick = onUploadButtonClick;
}
#Override
public int getItemContentLayout(int position) {
//TODO return the item layout of every position
return R.layout.upload_image_card;
}
}
And below is where i instantiate :
private void setCardSlider() {
upload = new ArrayList<>();
for(int i = 0; i < 3; i++){
upload.add(new ImageObject(i,false,""));
}
adapter = new UploadImageAdapter(getContext(), upload);
CardSliderViewPager cardSliderViewPager = rootView.findViewById(R.id.image_upload_slider);
cardSliderViewPager.setAdapter(adapter);
uploadDialog = new UploadDialog(getActivity(), getContext());
adapter.setOnUploadButtonClick((int position) -> {
uploadDialog.callUploadDialog();
mPosition = position;
});
}
public void uploadImage(){
uploadDialog.callUploadDialog();
}
public void setImage(Uri uri){
upload.get(mPosition).setHasImage(true);
upload.get(mPosition).setImage_path(uri.toString());
adapter.notifyDataSetChanged();
}

I would suggest using notifyItemChange instead. There you use a position as a parameter and it doesn't need to redraw everything.

Select only one image in RecyclerView

I have a RecyclerView.Adapter which has some Arrays there.
ArrayList with Strings and ArrayList with Integer. Strings are like url and Integer is the photo.
When the app is open for first time the first item is selected.
I have another method for click which makes another item as selected and this works, but the problem is that the first item stays as selected and so for every image click makes as selected, I want only one item to be selected and take a color.
This is my code.
Adapter of RecyclerView
public class ListViewAdapter extends RecyclerView.Adapter<ListViewAdapter.ViewHolder>{
private int selectedItem;
private ArrayList<Integer> mImages = new ArrayList<>();
private ArrayList<String> mSearchUrl = new ArrayList<>();
private Context mContext;
public ListViewAdapter(ArrayList<Integer> images, ArrayList<String> SearchUrl, Context context) {
mImages = images;
mContext = context;
mSearchUrl = SearchUrl;
}
#NonNull
#Override
public ViewHolder onCreateViewHolder(#NonNull ViewGroup viewGroup, int i) {
View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.s_engine_item, viewGroup, false);
return new ViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull final ViewHolder viewHolder, final int i) {
selectedItem = 0;
if (selectedItem == i) {
viewHolder.image.setBackgroundColor(Color.parseColor("#30000000"));
}
Glide.with(mContext).load(mImages.get(i))
.into(viewHolder.image);
viewHolder.searchUrl.setText(mSearchUrl.get(i));
viewHolder.image.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
viewHolder.image.setBackgroundColor(Color.parseColor("#30000000"));
selectedItem = i;
}
});
}
#Override
public int getItemCount() {
return mImages.size();
}
public class ViewHolder extends RecyclerView.ViewHolder{
ImageView image;
TextView searchUrl;
public ViewHolder(#NonNull View itemView) {
super(itemView);
image = itemView.findViewById(R.id.ivEngine);
searchUrl = itemView.findViewById(R.id.ivEngineText);
}
}
}
And this is the MainActivity.class
public void intSearch() {
mImages.add(R.drawable.s_bing);
mSearchUrl.add("https://www.bing.com/search?q=");
mImages.add(R.drawable.s_google);
mSearchUrl.add("https://www.google.com/search?q=");
mImages.add(R.drawable.s_yahoo);
mSearchUrl.add("www.yahoo.com");
mImages.add(R.drawable.amazon_white256);
mSearchUrl.add("www.amazon.com");
mImages.add(R.drawable.amazon_white256);
mSearchUrl.add("www.amazon.com");
mImages.add(R.drawable.amazon_white256);
mSearchUrl.add("www.amazon.com");
initRecyclerView();
}
private void initRecyclerView() {
LinearLayoutManager layoutManager = new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false);
RecyclerView recyclerView = findViewById(R.id.lvEngines);
recyclerView.setLayoutManager(layoutManager);
ListViewAdapter adapter = new ListViewAdapter(mImages, mSearchUrl, this);
recyclerView.setAdapter(adapter);
}

Initialize your selected item globally
public class ListViewAdapter extends RecyclerView.Adapter<ListViewAdapter.ViewHolder>{
private int selectedItem = 0;
.....
Then inside your onBindViewHolder whenever you click a new Image notify your adapter for changes in the last selected item cell.
viewHolder.image.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int previousSelectedItem = selectedItem;
selectedItem = i;
notifyItemChanged(previousSelectedItem);
viewHolder.image.setBackgroundColor(Color.parseColor("#30000000"));
}
});

Just remove this line from onBindViewHolder
selectedItem = 0;
and add an else to the background condition, like:
if (selectedItem == i) {
viewHolder.image.setBackgroundColor(Color.parseColor("#30000000"));
}else{
viewHolder.image.setBackgroundColor(“YOUR_DEFAULT_COLOR”);
}
and update the onClick:
viewHolder.image.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
selectedItem = i;
notifyDataSetChanged();
}
});

How avoid refresh checkbox while expand list in android

I'm making NLevel expandable list using listview. I've added checkbox only last level data in list view. I have stuck in below scenario.
If I check checkbox then when I expand listview means checkbox gets automatically unchecked.I don't want it to be like that. If I checked checkbox it should stay checked until I uncheck manually.
Please anyone help me!! It's been two days I stuck here.
Here goes my code:
MainActivity.java

Thanks in advance!!

i think you need to store the checkbox state in a boolean (is checked), and reflect that on the view, when getView() is called.
1- Add boolean checked to NLevelItem :
private boolean checked = false;
//add setter: setChecked(boolean)
//add getter isChecked()
2- Use that boolean in getView() (last one where checkbox is added)
#Override
public View getView(final NLevelItem item) {
// .......
final CheckBox checkBox = (CheckBox)view.findViewById(R.id.check);
checkBox.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//store checkbox state, note that NLevelItem item might need to be defined with 'final'
item.setChecked(checkBox.isChecked());
if(checkBox.isChecked()){
tempList.add((String) ((SomeObject)childs.getWrappedObject()).getName()+"+"+name);
}
else {
tempList.remove((String) ((SomeObject)childs.getWrappedObject()).getName()+"+"+name);
}
}//onClick()
}//setOnClickListener()
//update checkbox state from the corresponding NLevelItem
checkBox.setChecked(item.isChecked());
//.......
}//getView()
-EDIT:
to select 1 item, you need to iterate all items, set checked = false, but 1
i am not sure if you have to do it on:
List<NLevelItem> list;
or
List<NLevelListItem> filtered;
in the adapter class
private void selectOnly(int position){
for(int a=0;a<list.size();a++){
if(a == position){
list.get(a).setChecked(true);
continue;
}
list.get(a).setChecked(false);
}//for loop
notifyDataSetChanged(); // to update views (checkbox state)
}
Usage: selectOnly(15);

Use ViewHolder class to set and get Tag like this:
public class ListAdapter extends BaseAdapter {
private Context con;
private List<String> dataLt;
private static LayoutInflater inflater = null;
public ListAdapter(Context context, List<String> dataList){
con = context;
dataLt = dataList;
inflater = (LayoutInflater)con.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
return dataLt.size();
}
#Override
public Object getItem(int position) {
return position;
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View vi = convertView;
ViewHolder holder;
if(convertView==null){
/****** Inflate tabitem.xml file for each row ( Defined below ) *******/
vi = inflater.inflate(R.layout.list_item_search, null);
/****** View Holder Object to contain tabitem.xml file elements ******/
holder = new ViewHolder();
holder.textView = (TextView) vi.findViewById(R.id.textView);
/************ Set holder with LayoutInflater ************/
vi.setTag( holder );
}
else
holder=(ViewHolder)vi.getTag();
return vi;
}
public static class ViewHolder{
TextView textView;
}
}
Hope this may help.

Android custom list view data is not updating while using shared preference

I am trying to get the value from shared preference and display it in customized list view. But the problem is list view is not getting updated with second value, means first time it's perfectly working fine but second time it overwrites the first value or may be it is opening another screen and displaying over there.
I want to add all the shared preferences data in list view one by one. please help me to solve this. Following is my code.
ListModel.java
public class ListModel {
private String Title = "";
private String Description = "";
/*********** Set Methods ******************/
public void setTitle(String Title) {
this.Title = Title;
}
public void setDescription(String Description) {

OnItemClickListener(int position) {
mPosition = position;
}
#Override
public void onClick(View arg0) {

sct.onItemClick(mPosition);
}
}
}
Class Which reads shared preferencedata
public class Assignment extends Activity {

}
});
}
public void setListData() {
final ListModel sched = new ListModel();
/******* Firstly take data in model object ******/

}
public void onItemClick(int mPosition) {

.get(mPosition);
Toast.makeText(
CustomListView,
"" + tempValues.getTitle() + "" + ""
+ tempValues.getDescription(), Toast.LENGTH_LONG)
.show();
}
}
This function shows how i am writing data in shared Preference
public void sharedPrefernces() {
if (Code.title != null)
PreferenceConnector.writeString(this, PreferenceConnector.TITLE,
Code.title);
if (Code.description != null)
PreferenceConnector.writeString(this, PreferenceConnector.DESC,
Code.description);
}

In setListData() you're only adding 1 item to the Adapter, so the listView is not going to have the 2nd item shown.
