My 2D array has 5x3. In array I have stored id, name, image source string. I trying to put these values in Adapter to make newInstance, but all values in Fragment are passed as null.
My Adapter:
private class ScreenSlidePagerAdapter extends FragmentStateAdapter {
ScreenSlidePagerAdapter(FragmentActivity fa) {
super(fa);
}
#Override
public Fragment createFragment(int position) {
if (position < q_question.length) {
int i = 0;
int id = 0;
String name = "";
String src = "";
while (i < 5) {
if (!TextUtils.isEmpty(q_question[i][0]) && TextUtils.isDigitsOnly(q_question[i][0])) {
id = Integer.parseInt(q_question[i][0]);
}
name = q_question[i][1];
src = q_question[i][2];
i++;
}
return ScreenSlidePageFragment.newInstance2(id, name, src);
}else
return null;
}
#Override
public int getItemCount() {
return q_question.length;
}
}
My Fragment:
public class ScreenSlidePageFragment extends Fragment {
private static final String ARG_RESOURCE_ID = "resource_id";
private static final String ARG_RESOURCE_NAME = "resource_name";
private static final String ARG_RESOURCE_SRC = "resource_src";
private int id;
private String Name;
private String Src;
public ScreenSlidePageFragment() {
// Required empty public constructor
}
public static Fragment newInstance2(int id, String name, String src) {
ScreenSlidePageFragment fragment = new ScreenSlidePageFragment();
Bundle args = new Bundle();
args.putInt(ARG_RESOURCE_ID, id);
args.putString(ARG_RESOURCE_NAME, name);
args.putString(ARG_RESOURCE_SRC, src);
fragment.setArguments(args);
return fragment;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (getArguments() != null) {
id = getArguments().getInt(ARG_RESOURCE_ID);
Name = getArguments().getString(ARG_RESOURCE_NAME);
Src = getArguments().getString(ARG_RESOURCE_SRC);
}
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_screen_slide_page, container, false);
// assign our image's resource id here
ImageView imageView = view.findViewById(R.id.question_image);
Button button = view.findViewById(R.id.answer_one);
imageView.setImageDrawable(Drawable.createFromPath(Src));
button.setText(Name);
Log.e("test", id + Src +"//"+ Name); // There id always are 3, and src and name null
return view;
}
}
Have no time to answer, but i managed it myself.
Removing while (i < 5) statement from ScreenSlidePagerAdapter and leave all code in it outside statement, and all working.

I want to scrape MAL for character imgurl to later display using Picasso and name of character but am having troubles accessing the correct class files.
Here is the website under inspect. TYSM in advance.
Inspect MAL
Here is my CharacterList class which identifies the HTML classes
private RecyclerView recyclerView;
private ParseAdapter adapter;
private ArrayList<ParseItem> parseItems = new ArrayList<>();
private ProgressBar progressBar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_to_watch_list);
configureBackButton();
progressBar = findViewById(R.id.progressBar);
recyclerView = findViewById(R.id.recyclerView_character);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
adapter = new ParseAdapter(parseItems, this);
recyclerView.setAdapter(adapter);
Content content = new Content();
content.execute();
}
private class Content extends AsyncTask<Void, Void,Void>{
#Override
protected void onPreExecute() {
super.onPreExecute();
progressBar.setVisibility(View.VISIBLE);
progressBar.setAnimation(AnimationUtils.loadAnimation(CharacterList.this, android.R.anim.fade_in));
}
#Override

super.onPostExecute(aVoid);
progressBar.setVisibility(View.GONE);
progressBar.setAnimation(AnimationUtils.loadAnimation(CharacterList.this, android.R.anim.fade_out));
adapter.notifyDataSetChanged();
}

Document doc = Jsoup.connect(url).get();
Elements data = doc.select("tr.people");
int size = data.size();
for (int i = 0; i < size; i++){
String imgUrl = data.select("a.mr8.ml12.fl-l")
.select("img")
.eq(i)
.attr("src");
String title = data.select("tr.mt24.di-ib.information")

Log.d("items", "img: " +imgUrl + " .title: " + title);
}
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
}
I believe my ParseAdapter and ParseItem are working but just in case here they are
public class ParseAdapter extends RecyclerView.Adapter<ParseAdapter.ViewHolder> {
private ArrayList<ParseItem> parseItems;
private Context context;
public ParseAdapter(ArrayList<ParseItem> parseItems, Context context){
this.parseItems = parseItems;
this.context = context;
}
#NonNull
#Override
public ParseAdapter.ViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.parse_item, parent, false);
return new ViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull ParseAdapter.ViewHolder holder, int position) {
ParseItem parseItem = parseItems.get(position);
holder.textView.setText(parseItem.getTitle());
Picasso
//with vs get()
.with(this.context)
.load(parseItem.getImgurl())
.into(holder.imageView);
}
#Override
public int getItemCount() {
return parseItems.size();
}
public class ViewHolder extends RecyclerView.ViewHolder{
ImageView imageView;
TextView textView;
public ViewHolder(#NonNull View itemView) {
super(itemView);
imageView = itemView.findViewById(R.id.imageView_character);
textView = itemView.findViewById(R.id.textView_character);
}
}
}
public class ParseItem {
private String imgurl;
private String title;
public ParseItem(){
}
public ParseItem(String imgurl, String title) {
this.imgurl = imgurl;
this.title = title;
}
public String getImgurl() {
return imgurl;
}
public void setImgurl(String imgurl) {
this.imgurl = imgurl;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}}
I figured it out nevermind. Here is the class identification part in case anyone is stuck later on.
Elements data = doc.select("td.people");
int size = data.size();
for (int i = 0; i < size; i++){
String imgUrl = data.select("a.fl-l.ml12.mr8")
.select("img")
.eq(i)
.attr("data-src");
String title = data.select("div.information.di-ib.mt24")
.select("a.fs14.fw-b")
.eq(i)
.text();
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);
}
}

I want to add multiple items of same date in same single single card view but instead it is creating multiple Card View for multiple items of same date
You have to use RecyclerView Multiple ViewTypes. for detail please check this example.
Also visit this example.
Yeah I found the solution it worked perfect for Me.....we
have to just make changes to the card View by removing
spaces..
.
like this below...
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="wrap_content"
card_view:cardMaxElevation="0.1dp"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:background="#303030"
card_view:cardElevation="5dp"
android:foreground="?android:attr/selectableItemBackground"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_marginLeft="#dimen/dp_2"
android:layout_marginRight="#dimen/dp_2">
<...Your All Text Boxes and further Layout inside this
cardView...>
</android.support.v7.widget.CardView>
and I have add Header for each CardView....and it looks like
this
Outout is shown in below image
I need your help I am new in android programming. How can I save all the content in the list view save into text file this is my code of try to save the file but the problem is how can i put the listview array list to get the data i don't know how to put it where to put it please help how to do it to save the content of my listview
