STRIKE_THRU_TEXT_FLAG not working as Expected

STRIKE_THRU_TEXT_FLAG not working as Expected - java

This is my RecyclerView Adaptor Class
public class TodoAdaptor extends RecyclerView.Adapter<TodoAdaptor.SingleTodoView> {
private CheckBox checkbox;
private TextView title, dueDate;
private Context context;
private ArrayList<SingleTodo> todoList;
private onItemCLickListener itemCLickListener;

this.context = context;
this.todoList = todoList;
this.itemCLickListener = onItemClickListener;
}
#NonNull

public SingleTodoView onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.single_todo, parent, false);
return new SingleTodoView(v, itemCLickListener);
}
#Override
public void onBindViewHolder(#NonNull SingleTodoView holder, int position) {
SingleTodo singleTodo = todoList.get(position);
checkbox.setChecked(singleTodo.isComplete());
title.setText(singleTodo.getTitle());
if (singleTodo.isComplete()) {
title.setPaintFlags(title.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG);
Toast.makeText(context, "IsCompleted", Toast.LENGTH_SHORT).show();
} else {

Toast.makeText(context, "Not IsCompleted", Toast.LENGTH_SHORT).show();
}
if (singleTodo.getDueDate().isEmpty()) {
dueDate.setVisibility(View.GONE);
} else {

}
}
#Override
public int getItemCount() {

}
class SingleTodoView extends RecyclerView.ViewHolder {
private SingleTodoView(#NonNull View itemView, final onItemCLickListener itemCLickListener) {
super(itemView);
checkbox = itemView.findViewById(R.id.todo_list_completed_checkbox);
title = itemView.findViewById(R.id.todo_list_title);
dueDate = itemView.findViewById(R.id.todo_list_due_date);
title.setOnClickListener(new View.OnClickListener() {

checkbox.setOnClickListener(new View.OnClickListener() {

}
});
}
}
public interface onItemCLickListener {

}
}
This is My Adaptor
todoAdaptor = new TodoAdaptor(this, singleTodoArrayList, new TodoAdaptor.onItemCLickListener() {
#Override
public void onTextClickListener(int position) {
singleTodo = singleTodoArrayList.get(position);
singleTodo.setTitle("This is Test");
singleTodoArrayList.set(position, singleTodo);
todoAdaptor.notifyItemChanged(position);
}
#Override
public void onCheckboxClickListener(int position) {
singleTodo = singleTodoArrayList.get(position);
singleTodo.setComplete(!singleTodo.isComplete());
singleTodoArrayList.set(position, singleTodo);
todoAdaptor.notifyItemChanged(position);
}
});
and This is my SingleTodo Class
package com.example.simpletodo.classes;
public class SingleTodo {
private int id;
private String title;
private String dueDate;
private boolean isComplete;
public SingleTodo(int id, String title, String dueDate, boolean isComplete) {
this.id = id;
this.title = title;
this.dueDate = dueDate;
this.isComplete = isComplete;
}
public int getId() {
return id;
}
public String getTitle() {
return title;
}
public String getDueDate() {
return dueDate;
}
public boolean isComplete() {
return isComplete;
}
public void setId(int id) {
this.id = id;
}
public void setTitle(String title) {
this.title = title;
}
public void setDueDate(String dueDate) {
this.dueDate = dueDate;
}
public void setComplete(boolean complete) {
isComplete = complete;
}
}
Whenever I check the checkbox, Text of that item should paint Strikethrough and Its not working as Expected
I have 3 Items in the list, when i click checkbox Item get Checked and Text Strikethrough works but when i again click checkbox checkbox stay checked (although Object is being Updated as it should be) and strikethrought text revert to normal, and i have to click checkbox twice again for check box to get unchecked
other issue is that when i checked on item and then i try to check other item, Current Item text get replaced by one of the other checked item Text.
Images :
Default:
When i click the Checkbox Once:
When i Click the Checkbox Again:
When i Checked multiple Items one by one(I have not changed position of any item before checking they was in default order and after checking --in order-- this is what i get)
Any Help is Appreciated. I just want my code to work as Expected.

I found the Solution from this Question
I had to change my Adaptor Class. I Declared Views inside my view holder class and onBindViewHolder, i am using first parameter (holder) to get my Views
public class TodoAdaptor extends RecyclerView.Adapter<TodoAdaptor.SingleTodoView> {
private boolean darkTheme;
private Context context;
private ArrayList<SingleTodo> todoList;
private onItemCLickListener itemCLickListener;
public TodoAdaptor(Context context, ArrayList<SingleTodo> todoList, boolean darkTheme, onItemCLickListener onItemClickListener) {
this.darkTheme = darkTheme;
this.context = context;
this.todoList = todoList;
this.itemCLickListener = onItemClickListener;
}
#NonNull
#Override
public SingleTodoView onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View v = LayoutInflater.from(context).inflate(R.layout.single_todo, parent, false);
return new SingleTodoView(v, itemCLickListener);
}
#Override
public void onBindViewHolder(#NonNull SingleTodoView holder, int position) {
SingleTodo singleTodo = todoList.get(position);
holder.checkbox.setChecked(singleTodo.isComplete());
holder.title.setText(singleTodo.getTitle());
if (singleTodo.isComplete()) {
holder.title.setPaintFlags(holder.title.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG);
} else {
holder.title.setPaintFlags(holder.title.getPaintFlags() & (~Paint.STRIKE_THRU_TEXT_FLAG));
}
if (singleTodo.getDueDate().isEmpty()) {
holder.dueDate.setVisibility(View.GONE);
} else {
holder.dueDate.setVisibility(View.VISIBLE);
holder.dueDate.setText(singleTodo.getDueDate());
}
}
#Override
public int getItemCount() {
return todoList.size();
}
class SingleTodoView extends RecyclerView.ViewHolder {
private CheckBox checkbox;
private TextView title, dueDate;
private SingleTodoView(#NonNull View itemView, final onItemCLickListener itemCLickListener) {
super(itemView);
checkbox = itemView.findViewById(R.id.todo_list_completed_checkbox);

This happens when you try to have a structure like this in the database:
"list": {
"-Nasdueqriyew": "First value",
"-Nberqiy39esd": "Second value",
"-Nc3hadsiuhad": "Third value"
}
And then try to map it to a List or array in your Java class.
The JSON structure is not a list, because it was pairs of keys and values, which in Java translates to:
Map<String, Object>
So most likely, the List<itemData> in your code needs to be a Map<String, itemData>.

Open an specific activity when I click an item from an recyclerView

I need some help with two of my recycler views(one named "recentRecycler", and the other "topPlacesRecycler").My question is, how do I make to be redirected on a specific Activity when I click a specific item from the recycler. For example:
1- when I click the first item from the "recentRecycler" to be redirected to "Parlament.class"
2- when I click the first item from the "topPlacesRecycler" to be redirected to "Ramada.class"

I'm pretty new with Android Studio so every feedback would be gladly accepted.
Thanks in advance!

The best solution that does not overload the adapter would be to use interface.
Declare an interface in your adapter like this...
public class RecentsAdapter extends RecyclerView.Adapter<RecentsAdapter.RecentsViewHolder> {
Context context;
List<RecentsData> recentsDataList;
private RecentsAdapter.OnRecentItemclickListener listener;
public void setOnRecentItemclickListener(RecentsAdapter.OnRecentItemclickListener listener){
this.listener = listener;
}
public RecentsAdapter(Context context, List<RecentsData> recentsDataList) {
this.context = context;
this.recentsDataList = recentsDataList;
}
#NonNull
#Override
public RecentsViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(context).inflate(R.layout.recents_row_item, parent, false);
return new RecentsViewHolder(view, listener);
}
#Override
public void onBindViewHolder(#NonNull RecentsViewHolder holder, int position) {
holder.countryName.setText(recentsDataList.get(position).getCountryName());
holder.placeName.setText(recentsDataList.get(position).getPlaceName());
holder.price.setText(recentsDataList.get(position).getPrice());
holder.placeImage.setImageResource(recentsDataList.get(position).getImageUrl());
}
#Override
public int getItemCount() {
return recentsDataList.size();
}
public static final class RecentsViewHolder extends RecyclerView.ViewHolder{
ImageView placeImage;
TextView placeName, countryName, price;
public RecentsViewHolder(#NonNull View itemView, RecentsAdapter.OnRecentItemclickListener listener) {
super(itemView);
placeImage = itemView.findViewById(R.id.place_image);
placeName = itemView.findViewById(R.id.place_name);
countryName = itemView.findViewById(R.id.country_name);
price = itemView.findViewById(R.id.price);
itemView.setOnclickListener( -> {
if(listner == null)return;
int pos = getAdapterposition()
if(pos == RecyclerView.NO_POSITION)return;
listner.onRecentItemclickListener(pos);
});
}
}
public interface OnRecentItemclickListener {
void onRecentItemClickListener(int position);
}
}
Add then in you activity
private void setRecentRecycler(List<RecentsData> recentsDataList){
recentRecycler = findViewById(R.id.recent_recycler);
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(this, RecyclerView.HORIZONTAL, false);
recentRecycler.setLayoutManager(layoutManager);
recentsAdapter = new RecentsAdapter(this, recentsDataList);
recentRecycler.setAdapter(recentsAdapter);
recentsAdapter.setOnRecentItemclickListener(this::onOpenParlamentClass)
}
private void onOpenParlamentClass(int position){
//perform your intent here. you can also get the clicked item using the position of the data list and pass it to the receiving activity
}
Happy coding. If you are new to android you can also consider Kotlin.

public static final class RecentsViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
ImageView placeImage;
TextView placeName, countryName, price;
public RecentsViewHolder(#NonNull View itemView) {
super(itemView);
placeImage = itemView.findViewById(R.id.place_image);
placeName = itemView.findViewById(R.id.place_name);
countryName = itemView.findViewById(R.id.country_name);
price = itemView.findViewById(R.id.price);
itemView.setOnClickListener(this);
//you can do same code for another recyclerview.
}
#Override
public void onClick(View view) {
Intent intent = new Intent(context, Parlament.class);
view.getContext().startActivity(intent);
}
}

How to Highlighted single Text and background color when using recycle view

I'll use RecyclerView And I've more than 10 items in the list And I Have to change a text color and background layout on a single click of the item and else all the item color not change. Please suggest me the right way to solve this issue. I'll try to change the color in BindViewHolder, ViewHolder and Adapter click item but I'm Successful to change the color but unsuccessful to change the color back.

How to debug this runtime error?

This is a part java file which has the function loadMenu and when the corresponding intent opens, the app closes unexpectedly.
private void loadMenu() {
FirebaseRecyclerAdapter<Category,MenuViewHolder> adapter = new FirebaseRecyclerAdapter<Category, MenuViewHolder> (Category.class,R.layout.item_menu,MenuViewHolder.class,category) {
#Override
protected void populateViewHolder(MenuViewHolder viewHolder, Category model, int position) {
viewHolder.txtMenuname.setText(model.getName());
Picasso.with(getBaseContext()).load(model.getImage())
.into(viewHolder.imageView);
final Category clickItem = model;
viewHolder.setItemClickListener(new ItemClickListener() {
#Override
public void OnClick(View view, int position, boolean isLongClick) {
Toast.makeText(navi.this,""+clickItem.getName(),Toast.LENGTH_SHORT).show();
}
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
}
});
}
};
recycle_menu.setAdapter(adapter);
}
This is my MenuviewHolder class:I just created a database for images in firebase and linking it to my app, but its not showing images just background.
public class MenuViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
public TextView txtMenuname;
public ImageView imageView;
private ItemClickListener itemClickListener;
public MenuViewHolder(View itemView) {
super(itemView);
txtMenuname = (TextView)itemView.findViewById(R.id.menu_name);
itemView = (ImageView)itemView.findViewById(R.id.menu_image);
itemView.setOnClickListener(this);
}
public void setItemClickListener(ItemClickListener itemClickListener){
this.itemClickListener = itemClickListener;
}
#Override
public void onClick(View view) {
itemClickListener.OnClick(view,getAdapterPosition(),false);
}
}
