RecyclerView catch catch onItemClickListener

RecyclerView catch catch onItemClickListener - android

I have 2 RecyclerViews that uses the same XML file to inflate views through the adapter.
One RecyclerView does catch clicks while the other doesn't.
The first RecyclerView is on another fragment and the code is similar to the second RecyclerView.
I have tried a lot of changes to the XML file(MaterialCardView) such as removing clickable attribute or changing the layout_weight to be 1 on the card but all of them didn't work.
Also, I can't understand why it would work only on 1 with the same settings on the other.
Here is the code for the second part which is not working:
Fragment - section of matter
list = view.findViewById(R.id.user_display_details_rv); //Getting the RecyclerView
list.setHasFixedSize(true);
int numOfColumns = 2;
list.setLayoutManager(new GridLayoutManager(getContext(), numOfColumns,GridLayoutManager.VERTICAL,false));
adapter = new UserDisplayDetailsAdapter(viewModel,getLayoutInflater());
list.setAdapter(adapter);
list.addItemDecoration(new RecyclerView.ItemDecoration() {
#Override
public void getItemOffsets(#NonNull Rect outRect, #NonNull View view, #NonNull RecyclerView parent, #NonNull RecyclerView.State state) {
outRect.set(5,20,5,20);
}
});
adapter.setOnItemClickListener((v,pos)->{
String pollId = Objects.requireNonNull(viewModel.getUserFilledPolls().get(pos).getPollId());
Navigation.findNavController(v).navigate(FragmentUserDisplayDetailsDirections.actionFragmentUserDisplayDetailsToFragmentOtherUserPoll(pollId,userId));
});
Adapter
public class UserDisplayDetailsAdapter extends RecyclerView.Adapter<UserDisplayDetailsHolder> {
UserDisplayDetailsViewModel viewModel;
LayoutInflater layoutInflater;
OnItemClickListener onItemClickListener;
public UserDisplayDetailsAdapter(UserDisplayDetailsViewModel viewModel, LayoutInflater layoutInflater) {
this.viewModel = viewModel;
this.layoutInflater = layoutInflater;
}
#NonNull
#Override
public UserDisplayDetailsHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
LayoutInflater inflater = (LayoutInflater) MyApplication.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.poll_list_square,parent,false);
return new UserDisplayDetailsHolder(view,onItemClickListener);
}
#Override
public void onBindViewHolder(#NonNull UserDisplayDetailsHolder holder, int position) {
Poll poll = Objects.requireNonNull(viewModel.getUserFilledPolls().get(position));
holder.bind(poll);
}
#Override
public int getItemCount() {
if(viewModel.getUserFilledPolls() == null){
return 0;
}
return viewModel.getUserFilledPolls().size();
}
public void setOnItemClickListener(OnItemClickListener listener){
this.onItemClickListener = listener;
}
}
Holder
public class UserDisplayDetailsHolder extends RecyclerView.ViewHolder {
MaterialTextView pollsName;
ShapeableImageView icon;
public UserDisplayDetailsHolder(#NonNull View itemView, OnItemClickListener onItemClickListener) {
super(itemView);
pollsName = itemView.findViewById(R.id.homescr_poll_pollName);
icon=itemView.findViewById(R.id.homescr_poll_icon);
itemView.setOnClickListener(v->{
int pos = getAdapterPosition();
onItemClickListener.onItemClick(v,pos);
});
}
public void bind(Poll poll) {
pollsName.setText(poll.getPollName());
}
}

Recyclerview expanding itself

I am trying to do same design in here. I have nested Recyclerview in my structure. I have BasketParentItem class and it keeps child products list. As you can see in here when i click the checkbox list expanding itself. This happens when i call notifyDataChangeSetChildAndParent() in listener. Any idea how to solve it ?
Edit: I solved problem. I removed divider on parent adapter now it's working well here
holder.rv_child_Basket_Parent.addItemDecoration(new DividerItemDecoration(mActivity.getApplicationContext(), DividerItemDecoration.VERTICAL));
holder.cb_Basket_CardView_Child.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if(list.get(position).isChecked()){
holder.cb_Basket_CardView_Child.setChecked(false);
list.get(position).setChecked(false);
}else{
holder.cb_Basket_CardView_Child.setChecked(true);
list.get(position).setChecked(true);
}
boolean allCheck = false;
for (BasketParentItem b : Basket.basketList) {
ArrayList<MyProduct> tempList = b.getChildItemList();
if (tempList.contains(list.get(position)) ) {
for (MyProduct mP : tempList) {
if(mP.isChecked()){
allCheck = true;
}
}
if(!allCheck){
//set parent uncheck
b.setChecked(false);
}
}
}
notifyDataChangeSetChildAndParent();
}
});

Android: Custom List View is not working properly

My apologies for not providing a proper source code.
basically what I have in my list view xml layout is:
listleave.xml
leaveSummary.xml
leavedB
Custom Adapter
ApplyLeave
I'm creating an app where I have a list view and when I'm running my app I'm getting an error in Locgat.
Caused by:java.lang.NullPointerException: Attempt to invoke virtual
method 'void
android.widget.ListView.setAdapter(android.widget.ListAdapter)' on a null
object reference
at com.example.huzai.civilsoft1.ApplyLeave.loadDataInListView(ApplyLeave.java:258 )
at com.example.huzai.civilsoft1.ApplyLeave.onCreate(ApplyLeave.java:84)
In the line loadDataInListView when I'm not commenting l1.setAdapter(customAdapter); the app crashes but when I'm commenting it works properly.
Result of not commenting: l1.setAdapter(customAdapter);

Please tell me where I'm going wrong.

You are getting null l1.
Confirm your id of ListView in your activity_apply_leave.xml. It should be leaveApplicationSummary.
EDIT:
Your ListView is in listleave.xml but you are using activity_apply_leave.xml in your Activity.
Move your ListView from listleave.xml to activity_apply_leave.xml.

Recycleview custom layout constraint are changing for each inflated view causing problems

I have a recyclerview that inflates data fetched from json.
The issue I am facing are design issues - sometimes the text is aligned correctly and the image is shown and sometimes the text is too long, causing what I think is for the image not to be shown.
here is my XML:
<?xml version="1.0" encoding="utf-8"?>

android:id="#+id/heroImage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

android:src="#mipmap/ic_launcher"
app:layout_constraintBottom_toBottomOf="parent"

<TextView

android:layout_marginTop="16dp"
android:layout_marginEnd="16dp"
android:autoSizeMaxTextSize="25dp"
android:autoSizeMinTextSize="15dp"
android:text="Hero Title"
android:textSize="25dp"
android:textStyle="bold"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:id="#+id/heroDescription"
android:layout_width="200dp"

app:layout_constraintStart_toEndOf="#+id/heroImage"
app:layout_constraintTop_toBottomOf="#+id/heroTitle" />
</android.support.constraint.ConstraintLayout>
</android.support.constraint.ConstraintLayout>
and here is my adapter:
public class HeroesAdapter extends RecyclerView.Adapter<HeroesAdapter.HeroesViewHolder> {
private List<Hero> heroList;
public HeroesAdapter(List<Hero> heroList) {
this.heroList = heroList;
}
#NonNull
#Override
public HeroesViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View rowView = LayoutInflater.from(parent.getContext()).inflate(R.layout.hero_cell, parent, false);
return new HeroesViewHolder(rowView);
}
#Override
public void onBindViewHolder(#NonNull HeroesViewHolder holder, int position) {
Hero currentHero = heroList.get(position);
String str = String.join(",", currentHero.abilities);
holder.heroTitle.setText(currentHero.title);
holder.heroAbilties.setText(str);
Picasso.get().load(currentHero.image).resize(500,500).into(holder.heroesImage);
}
#Override
public int getItemCount() {
return heroList.size();
}
public static class HeroesViewHolder extends RecyclerView.ViewHolder {
ImageView heroesImage;
TextView heroTitle;
TextView heroAbilties;
public HeroesViewHolder(#NonNull View itemView) {
super(itemView);
heroesImage = itemView.findViewById(R.id.heroImage);
heroTitle = itemView.findViewById(R.id.heroTitle);
heroAbilties = itemView.findViewById(R.id.heroDescription);
}
}
}
This is the result I am getting and this is the wanted result.
the issues I am facing are:
making each row have a clean design and act the same for all.
images are sometimes shown, sometimes not.
bottom view is "half in screen" and half out of screen.

By using LinearLayout you can design your hero_cell that will give you the desirable output. as I do it for now.

I want to manage RadioButton on click of both CardView and RadioButton , I have used following code:

public class FragmentListTransport extends Fragment implements View.OnClickListener {
FragmentListOfTransportBinding mBinding;
public FragmentListTransport() {
// Required empty public constructor
}
#Override
public View onCreateView(#NonNull LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
mBinding = DataBindingUtil.inflate(inflater, R.layout.fragment_list_of_transport, container, false);
mBinding.parentCard1.setOnClickListener(this);
mBinding.parentCard2.setOnClickListener(this);
mBinding.parentCard3.setOnClickListener(this);
mBinding.parentCard4.setOnClickListener(this);
return mBinding.getRoot();
}
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.parent_card_1:
mBinding.radioButton1.setChecked(true);
mBinding.radioButton2.setChecked(false);
mBinding.radioButton3.setChecked(false);
mBinding.radioButton4.setChecked(false);
break;
case R.id.parent_card_2:
mBinding.radioButton1.setChecked(false);
mBinding.radioButton2.setChecked(true);
mBinding.radioButton3.setChecked(false);
mBinding.radioButton4.setChecked(false);
break;
case R.id.parent_card_3:

mBinding.radioButton2.setChecked(false);
mBinding.radioButton3.setChecked(true);
mBinding.radioButton4.setChecked(false);

mBinding.radioButton1.setChecked(false);
mBinding.radioButton2.setChecked(false);
mBinding.radioButton3.setChecked(false);
mBinding.radioButton4.setChecked(true);
break;
}
}
}
Is there any best way to manage it?

I don't easiest way then following (If you have easy way then I will accept it.):
/**

public class FragmentListTransport extends Fragment implements View.OnClickListener {
FragmentListOfTransportBinding mBinding;
public FragmentListTransport() {

}
#Override

mBinding = DataBindingUtil.inflate(inflater, R.layout.fragment_list_of_transport, container, false);
mBinding.parentCard1.setOnClickListener(this);
mBinding.parentCard2.setOnClickListener(this);
mBinding.parentCard3.setOnClickListener(this);
mBinding.parentCard4.setOnClickListener(this);
mBinding.radioButton1.setOnClickListener(this);
mBinding.radioButton2.setOnClickListener(this);
mBinding.radioButton3.setOnClickListener(this);
mBinding.radioButton4.setOnClickListener(this);
return mBinding.getRoot();
}
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.parent_card_1:
case R.id.radio_button_1:
clickedRadioButton(mBinding.radioButton1);
break;
case R.id.parent_card_2:
case R.id.radio_button_2:
clickedRadioButton(mBinding.radioButton2);
break;
case R.id.parent_card_3:
case R.id.radio_button_3:
clickedRadioButton(mBinding.radioButton3);
break;
case R.id.parent_card_4:
case R.id.radio_button_4:
clickedRadioButton(mBinding.radioButton4);
break;
}
}
private void clickedRadioButton(RadioButton radioButton) {
mBinding.radioButton1.setChecked(false);
mBinding.radioButton2.setChecked(false);
mBinding.radioButton3.setChecked(false);
mBinding.radioButton4.setChecked(false);
radioButton.setChecked(true);
}
}
If anyone has easiest way then this, please post answer. I will accept.

But, when i run it i only see white background, i mean because this is bottomnavigationview i only can see the navigation from what i write above. How can i fix it, is there something missing ? Thanks in advance and sorry for my bad english.
Here is my ProfilFragment.java
public class ProfilFragment extends Fragment {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_profil, container, false);
SharedPreferences mPrefs = this.getActivity().getSharedPreferences("userinfoafterlogin", MODE_PRIVATE); //add key
String response = mPrefs.getString("userinfo", null);
try{
JSONObject json = new JSONObject(response);
json = (JSONObject)json.get("nameValuePairs");
json = (JSONObject)json.get("userData");
json = (JSONObject)json.get("nameValuePairs");
String fullname = (String)json.get("fullname");
String phone = (String)json.get("phone");
String desc = (String)json.get("Deskripsi");
TextView labelfullname = (TextView)v.findViewById(R.id.fullnametext);
TextView labeltelp = (TextView)v.findViewById(R.id.notelptext);
TextView labeldesc = (TextView)v.findViewById(R.id.deskripsitxt);
labelfullname.setText(fullname);
labeltelp.setText(phone);
labeldesc.setText(desc);
return v;
}catch (JSONException e) {
Log.e("MYAPP", "unexpected JSON exception", e);
return v;
}
}
}
