I am updating my recyclerview by using LiveData as below:
viewModel = ViewModelProviders.of(getActivity()).get(MyViewModel.class);
viewModel.getPurchaseList().observe(getViewLifecycleOwner(), new Observer<List<ProductsObject>>() {
#Override
public void onChanged(#Nullable List<ProductsObject> productsObjects) {
adapter.submitList(productsObjects);
//adapter.notifyDataSetChanged();
}
});
And I am using a FloatActionButton to change the value of my MutableLiveData as below:
FloatingActionButton fab = view.findViewById(R.id.cart_fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
viewModel.setPurchasePrice(0, 101.2);
}
});
All the data gets changed and onChanged is called as expected, but it only updates my recyclerview when I enable the adapter.notifyDataSetChanged();
If I create a new ProductsObject inside the FAB and submit a new list, the recyclerview gets updated without calling adapter.notifyDataSetChanged(); as below:
FloatingActionButton fab = view.findViewById(R.id.cart_fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//viewModel.setPurchaseAmount(0, 101.2);
ProductsObject prod = new ProductsObject("6666", 5, 152.2, "new product");
List<ProductsObject> prodList = new ArrayList<>();
prodList.add(prod);
adapter.submitList(prodList);
}
});
I appreciate if anyone could explain why.
Here is my adapter:
public class CartFragAdapter extends RecyclerView.Adapter<CartFragAdapter.CartFragViewHolder> {
private static final String TAG = "debinf PurchaseAdap";
private static final DiffUtil.ItemCallback<ProductsObject> DIFF_CALLBACK = new DiffUtil.ItemCallback<ProductsObject>() {
#Override
public boolean areItemsTheSame(#NonNull ProductsObject oldProduct, #NonNull ProductsObject newProduct) {
Log.i(TAG, "areItemsTheSame: old is "+oldProduct.getCode()+" ; new is "+newProduct.getCode());
return oldProduct.getCode().equals(newProduct.getCode());
}
#Override
public boolean areContentsTheSame(#NonNull ProductsObject oldProduct, #NonNull ProductsObject newProduct) {
Log.i(TAG, "areContentsTheSame: old is "+oldProduct.getPrice()+" ; new is "+newProduct.getPrice());
return oldProduct.getPrice() == newProduct.getPrice();
}
};
private AsyncListDiffer<ProductsObject> differ = new AsyncListDiffer<ProductsObject>(this, DIFF_CALLBACK);
#NonNull
#Override
public CartFragViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_purchase, parent, false);
return new CartFragViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull CartFragViewHolder holder, int position) {
final ProductsObject purchaseList = differ.getCurrentList().get(position);
holder.mCode.setText(purchaseList.getCode());
holder.mPrice.setText(String.valueOf(purchaseList.getPrice()));
holder.mDescription.setText(purchaseList.getDescription());
}
#Override
public int getItemCount() {
Log.i(TAG, "getItemCount");
return differ.getCurrentList().size();
}
public void submitList(List<ProductsObject> products){
Log.i(TAG, "submitList: products.size is "+products.size());
differ.submitList(products);
}
public class CartFragViewHolder extends RecyclerView.ViewHolder {
public TextView mCode, mPrice, mDescription;
public CartFragViewHolder(#NonNull View itemView) {
super(itemView);
mCode = (TextView) itemView.findViewById(R.id.item_productCode);
mPrice = (TextView) itemView.findViewById(R.id.item_productPrice);
mDescription = (TextView) itemView.findViewById(R.id.item_productDescription);
}
}
}
And here is my ViewModel:
public class MyViewModel extends ViewModel {
MutableLiveData<List<ProductsObject>> purchaseList = new MutableLiveData<>();
public LiveData<List<ProductsObject>> getPurchaseList() {
return purchaseList;
}
public void setPurchasePrice(int position, double price) {
List<ProductsObject> itemList = purchaseList.getValue();
if (itemList != null && itemList.get(position) != null) {
Log.i("debinf ViewModel", "setPurchaseAmount: "+itemList.get(position).getPrice());
itemList.get(position).setPrice(price);
purchaseList.postValue(itemList);
}
}
}
AsyncListDiffer saves only the reference of the list. This means that if you submit a modified list instead of submitting a new list, AsncListDiffer won't be able to detect any difference because both the previous list and the new list are referencing the same list with the same items.
To fix this you need to create a new list and new item. Change MyViewModel#setPurchasePrice as below:
public void setPurchasePrice(int position, double price) {
List<ProductsObject> itemList = purchaseList.getValue();
if (itemList != null && itemList.get(position) != null) {
List<ProductsObject> newList = new ArrayList<>();
for (int i = 0; i < itemList.size(); i++) {
ProductsObject prevProd = itemList.get(i);
if (i != position) {
newList.add(prevProd);
} else {
ProductsObject newProd = new ProductsObject(..., price, ...);
newList.add(newProd);
}
}
purchaseList.postValue(newList);
}
}

how to inser ViewPager in to Custom RecyclerView android?
please help me .
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType)

View view =
LayoutInflater.from(parent.getContext()).inflate(R.layout.mnlist ,
parent, false);
viewPager = (ViewPager) view.findViewById(R.id.viewpager);
setupViewPager(viewPager);
return new ListViewHolder(view);
}
What to write getSupportFragmentManager() ?
private void setupViewPager(ViewPager viewPager)
{
ViewPagerAdapter adapter = new
ViewPagerAdapter(getSupportFragmentManager());
adapter.addFragment(new HomeFragment(),"a");
adapter.addFragment(new OneFragment(), "b");
adapter.addFragment(new TwoFragment(),"c");
viewPager.setAdapter(adapter);
}
i write code following ,but not answer , Because "ForceClose Activity".
#Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
((ListViewHolder) holder).bindView(position);
ViewPagerAdapter adapter = new ViewPagerAdapter(((AppCompatActivity) ctx).getSupportFragmentManager());
viewPager.setAdapter(adapter);
tabLayout.setupWithViewPager(viewPager);
viewPager.setOffscreenPageLimit(2);
}
public class ViewPagerAdapter extends FragmentStatePagerAdapter {
private String[] tabTitles = new String[] {"Tab 1", "Tab 2"};

I'm trying to implement endless scrolling in my firebase recycler view.I limit my query to 5 items then the users scrolls to the end of the list the query is updated and the limit is increased my another 5. But the adapter only updates when i leave and return to the activity. I tried notifydatasetchange(), but that doesn't work. I tried recyclerview.setadapter(). It works but it also resets the scroll position of my recycler view.Nothing else seems to work.

when i run my app, i get much more radiobuttons than i need. It seems the radiobuttons repeat themselves in the same group. I don't really understand what is is going on. Here is my custom ArrayAdapter. I would like to know the problem here
public class QuestionsListAdapter extends ArrayAdapter<QuestionProperties> {
List<QuestionProperties> list;
Context test;
public QuestionsListAdapter(Context context, int resource, List<QuestionProperties> list2) {
super(context,resource,list2);
test = context;
list =list2;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view;
final RadioButton[] rB;
RadioHolder holder = new RadioHolder();
view= convertView;
LinearLayout.LayoutParams layoutParams = new RadioGroup.LayoutParams(
RadioGroup.LayoutParams.WRAP_CONTENT,
RadioGroup.LayoutParams.WRAP_CONTENT);
if(view == null)
{
LayoutInflater inflator = ((Activity) test).getLayoutInflater();
view = inflator.inflate(R.layout.question_list_row, null);
holder.questionTV = (TextView) view.findViewById(R.id.qTextView);
holder.radiogroup = (RadioGroup) view.findViewById(R.id.radio_group);
view.setTag(holder);
}
else{
//view = convertView;
holder = (RadioHolder) view.getTag();
}
holder.questionTV.setText(String.valueOf(list.get(position).getQuestionNo())+"."+" " + list.get(position).getQuestion());
rB=new RadioButton[list.get(position).possibleAns.length];
for(int count = 0; count<(list.get(position).possibleAns.length);count++)
{
rB[count]= new RadioButton(test);
rB[count].setId(count);
rB[count].setText(list.get(position).possibleAns[count]);
layoutParams.weight=1.0f;
layoutParams.setMargins(15, 0, 5, 10);
rB[count].setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
String a = String.valueOf(v.getId());
Toast.makeText(QActivity.context, "Radio Button "+ a,Toast.LENGTH_SHORT).show();
}
});
holder.radiogroup.addView(rB[count],layoutParams);
}
return view;
}
static class RadioHolder {
protected TextView questionTV;
protected RadioGroup radiogroup;
}
Finally after some hacks i solved it! i removed all the radio buttons in the else clause.
The solution..

//holder.radiogroup.check(list.get(position).getSelectedAns());

}
else{

holder.radiogroup.removeAllViews();
}
