I want to hide checkbox of all lists if I clicked one list within activity using recyclerview.
But when I implement it, only the check box in the recyclerview list of the clicked position disappears. How can I hide the checkbox of the entire list?
Of course it is possible on the reyclerview adapter, but I want this function to be implemented in activity.
In activity, the adapter was declared:
RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getApplicationContext());
recyclerViewAdapter = new RecyclerViewAdapter(this, patientList, selected_patientList);
recyclerView.setLayoutManager(mLayoutManager);
recyclerView.setItemAnimator(new DefaultItemAnimator());
recyclerView.setAdapter(recyclerViewAdapter);
And I wrote the code that hides the check box when click the recyclerview list in activity :
recyclerView.addOnItemTouchListener(new RecyclerItemClickListener(this, recyclerView, new RecyclerItemClickListener.OnItemClickListener() {
#Override
public void onItemClick(View view, int position) {
CheckBox checkBox = (CheckBox) view.findViewById(R.id.checkBox) ;
checkBox.setVisibility(View.GONE);
}
And my recyclerview adapter code is
public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.MyViewHolder> {
private Activity activity;
public ArrayList<PatientItem> patientList = new ArrayList<>();
public ArrayList<PatientItem> selected_patientList = new ArrayList<>();
Context mContext;
boolean checkboxIsVisible = true ;
public RecyclerViewAdapter(Context context, ArrayList<PatientItem> patientList, ArrayList<PatientItem> selected_patientList) {
this.mContext = context;
this.patientList = patientList;
this.selected_patientList = selected_patientList;
}
public class MyViewHolder extends RecyclerView.ViewHolder {
TextView patientType;
TextView clinicID;
TextView patientName;
TextView dateFirst;
TextView dateFinal;
CheckBox checkBox ;
ConstraintLayout cl_listitem;
public MyViewHolder(View itemView) {
super(itemView);
patientType = (TextView) itemView.findViewById(R.id.typeViewItem);
clinicID = (TextView) itemView.findViewById(R.id.clinicIDItem);
patientName = (TextView) itemView.findViewById(R.id.patientNameItem);
dateFirst = (TextView) itemView.findViewById(R.id.dateFirstItem);
dateFinal = (TextView) itemView.findViewById(R.id.dateFinalItem);
checkBox = (CheckBox) itemView.findViewById(R.id.checkBox) ;
cl_listitem = (ConstraintLayout) itemView.findViewById(R.id.cl_listitem);
}
}
#Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.patient_list_item, parent, false);
final RecyclerViewAdapter.MyViewHolder vHolder = new RecyclerViewAdapter.MyViewHolder(itemView) ;
return vHolder;
}
#Override
public void onBindViewHolder(MyViewHolder holder, int position) {
PatientItem data = patientList.get(position);
holder.patientType.setText(data.getPatientType());
holder.clinicID.setText(data.getClinicID());
holder.patientName.setText(data.getPatientName());
holder.dateFirst.setText(data.getDateFirst());
holder.dateFinal.setText(data.getDateFinal());
holder.checkBox.setChecked(data.isDeleteBox());
holder.checkBox.setVisibility(checkboxIsVisible?View.VISIBLE:View.GONE);
if(data.getPatientType() == "P"){
holder.patientType.setText("");
holder.patientType.setBackground(ContextCompat.getDrawable(mContext, R.drawable.parkinson));
}
else if(data.getPatientType() == "ET"){
holder.patientType.setText("");
holder.patientType.setBackground(ContextCompat.getDrawable(mContext, R.drawable.essential_tremor));
}
else{
holder.patientType.setText("ㅡ");
}
}
#Override
public int getItemCount() {
return patientList.size();
}
public void clear() {
int size = patientList.size() ;
patientList.clear() ;
notifyItemRangeRemoved(0, size);
}
//어댑터 정비
public void refreshAdapter() {
this.selected_patientList = selected_patientList;
this.patientList = patientList;
this.notifyDataSetChanged();
}
}
I solved this problem like this.
I declared onBindViewHolder at RecyclerViewAdapter:
holder.checkBox.setVisibility(checkboxIsVisible?View.VISIBLE:View.GONE);
And, I declared visible() method in RecyclerViewAdapter :
public void visible(){
checkboxIsVisible = false ;
this.notifyDataSetChanged();
}
Than, I use visible method in activity :
recyclerView.addOnItemTouchListener(new RecyclerItemClickListener(this, recyclerView, new RecyclerItemClickListener.OnItemClickListener() {
#Override
public void onItemClick(View view, int position) {
recyclerViewAdapter.visible();
}
When I run this, when I click on one list, all the check boxes on the list disappear.

I am using Recyclerview. I added a menu with Recyclerview. I want to make a switch case in Recyclerview. So when I click on item 1, when I click on item 2, I click on step 3. When I click on my item .. I want to call a function. Currently I tried to read the position of the items with getAdapterPosition, but the output is always -1. For example, when I click on model, when I click on model2, I want to call a function.

Please add this property in your parent layout in xml file
android:descendantFocusability="blocksDescendants"
Set adapter in RecyclerView as below:
private void setAdapter() {
recyclerView.setHasFixedSize(true);
mLayoutManager = new LinearLayoutManager(context, LinearLayoutManager.HORIZONTAL, false);
recyclerView.setLayoutManager(mLayoutManager);
recyclerView.setNestedScrollingEnabled(false);
recyclerView.setHasFixedSize(true);
mainAdapterClass = new MainAdapterClassw(context, AuctionManager.list);
recyclerView.setAdapter(mainAdapterClass);
}
In my case it was occurred because of gravity property inside EditText, It was like: android:gravity="center", So removing this property resolved the issue.
public class HashTagSearchAdapter extends RecyclerView.Adapter<HashTagSearchAdapter.HashTagViewHolder> {
Context context;
List<TagSearchObject> tagResponses;
public HashTagSearchAdapter (Context context, List<TagSearchObject> tagResponses){
this.context = context;
this.tagResponses = tagResponses;
for (int i =0;i<tagResponses.size();i++){
Log.e("tagfor",tagResponses.get(i).toString());
}
Log.e("constructor",tagResponses.size()+"");
Log.e("constructor","here");
}
#Override
public HashTagViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(context).inflate(R.layout.tag_search_list,parent,false);
Log.e("onCreate","here");
return new HashTagViewHolder(view);
}
#Override
public void onBindViewHolder(HashTagViewHolder holder, int position) {
TagSearchObject userTagResponse = tagResponses.get(position);
Log.e("tag",userTagResponse.toString());
holder.name.setText(userTagResponse.getName());
holder.count.setText(userTagResponse.getChallengeCount()+" public posts");
}
#Override
public int getItemCount() {
Log.e("getItemCount",this.tagResponses.size()+"");
return tagResponses.size();
}
class HashTagViewHolder extends RecyclerView.ViewHolder{
ImageView hashtag;
TextView name,count;
public HashTagViewHolder(View itemView) {
super(itemView);
name = (TextView) itemView.findViewById(R.id.name);
count = (TextView) itemView.findViewById(R.id.count);
}
}
}
here logcat is :
E/tagfor:TagSearchObject{id='1', name='hahah', challengeCount='1'}
E/constructor: 1
E/constructor: here
Because you have not added a layout manager and/or your recycler view is not visible. Since it's not visible, no attempt to draw is made and itemCount is never called because, well, there is nothing to draw.
set layout manager before setAdapter to the RecyclerView
LinearLayoutManager llm = new LinearLayoutManager(getApplicationContext());
HashTagSearchAdapter hashTagSearchAdapter = new
HashTagSearchAdapter(context,tagSearchObjects);
recyclerView.setLayoutManager(llm);
recyclerView.setAdapter(hashTagSearchAdapter);
I have made a RecyclerView adapter and using that adapter to inflate data in recycler view , I previously used the general Method of ListView onItemClickListner but it doesn't seems to work with RecyclerView , Plese anyone help me out with this
My RecyclerView Adapter class is :
public class TimeAdaptra extends
RecyclerView.Adapter<TimeAdaptra.RecyclerViewHolder> {
ArrayList<String> time, status;
public TimeAdaptra(ArrayList<String> title, ArrayList<String> dec) {
this.time = title;
this.status = dec;
}
#Override
public RecyclerViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.time_slice, parent, false);
RecyclerViewHolder recyclerViewHolder = new RecyclerViewHolder(view);
return recyclerViewHolder;
}
#Override
public void onBindViewHolder(RecyclerViewHolder holder, int position) {
holder.myTitle.setText(time.get(position));
holder.mydec.setText(status.get(position));
}
#Override
public int getItemCount() {
return time.size();
}
public static class RecyclerViewHolder extends RecyclerView.ViewHolder {
TextView myTitle;
TextView mydec;
public RecyclerViewHolder(View view) {
super(view);
myTitle = (TextView) view.findViewById(R.id.timee);
mydec = (TextView) view.findViewById(R.id.status);
}
}
}
And I am doing inflation like this :
public class Slots extends AppCompatActivity {
RecyclerView recyclerView;
RecyclerView.Adapter adapter;
RecyclerView.LayoutManager manager;
private ArrayList<String> Time = new ArrayList<String>();
private ArrayList<String> Status = new ArrayList<String>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_slots);
Time.add("18:00");
Status.add("Available");
recyclerView = (RecyclerView) this.findViewById(R.id.timeslice);
manager = new LinearLayoutManager(this);
recyclerView.setLayoutManager(manager);
recyclerView.setHasFixedSize(true);
adapter = new TimeAdaptra(Time, Status);
recyclerView.setAdapter(adapter);
adapter.notifyDataSetChanged();
Make the RecyclerViewHolder implement View.OnClickListener like this:
public static class RecyclerViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{
TextView myTitle;
TextView mydec;
public RecyclerViewHolder(View view) {
super(view);
myTitle = (TextView) view.findViewById(R.id.timee);
mydec = (TextView) view.findViewById(R.id.status);
myTitle.setOnClickListener(this);
mydec.setOnClickListener(this);
}
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.timee:
// do task
break;
case R.id.status:
//do task
break;
}
}
}
If you want to click on each item of the list then you should get the id of the root layout of the xml your are inflating and setOnClickListener() to it.
I here by attached my code.
I have a fragment with in that have recycler list item list.
If i click the recycler item on fragment i can't move to new activity.
And i want to get the recycler item value which item i have clicked.
So kindly please suggest me to how to intent fragment to activity once clicked recycler list item with in fragment and how to get the recycler item value?

}
// inner class to hold a reference to each item of RecyclerView
public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{

//imgViewIcon = (ImageView) itemLayoutView.findViewById(R.id.item_icon);
name=namelist.getText().toString();

itemLayoutView.setOnClickListener(this);
}
#Override public void onClick(View view) {
}
}
public interface OnItemClickListener {
public void onItemClick(View view , int position);
}
public void SetOnItemClickListener(final OnItemClickListener mItemClickListener) {
this.mItemClickListener = mItemClickListener;
}
// Return the size of your itemsData (invoked by the layout manager)
#Override
public int getItemCount() {
return itemsData.length;
}
} //Update - Code formatting
Modify your constructor DetailAdapter as following:
public DetailAdapter(Context context, DetailModel[] itemsData) {
this.context = context;
this.itemsData = itemsData;
}
On your onClick() method in adapter add following code:
#Override
public void onClick(View view) {
int pos = getAdapterPosition();
String tempName = itemsData[pos].getName();
String tempNumber = itemsData[pos].getNumber();
Intent intent = new Intent(context, YourActivity.class);
startActivity(intent);
}
Add this on your adapter,
View.OnClickListener mOnClickListener = new OrderClickListener();
then
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.contactnamenumber, parent, false);
view.setOnClickListener(mOnClickListener);
return new ViewHolder(view);
}
now in adapter,
private class OrderClickListener implements View.OnClickListener {
#Override
public void onClick(View v) {
mOrderSelect.onOrderSelect(rvOrderHistory.getChildLayoutPosition(v));
}
}
From above steps you can get the position which item is clicked. Here you can go to next activity.
