Expanding Listview using Recyclerview inside Scrollview

Expanding Listview using Recyclerview inside Scrollview - android

I tried below code to implement an expend and collapse content using recyclerview(listview) a link
final boolean isExpanded = position==mExpandedPosition;
holder.details.setVisibility(isExpanded?View.VISIBLE:View.GONE);
holder.itemView.setActivated(isExpanded);
if (isExpanded)
previousExpandedPosition = position;
holder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mExpandedPosition = isExpanded ? -1:position;
notifyItemChanged(previousExpandedPosition);
notifyItemChanged(position);
}
});
In my case when i click the particular position in recyclerview its expanding but it goes above the recyclerview.I cant see the full expanded content.i can see only partial content.In this case i need to scroll the recyclerview to view the full content.But i am searching for a solution to view the content without scroll the recyclerview. If i click another position in recyclerview that should be placed over an recyclerview.

Try to use NestedScrollView instead of ScrollView and set below to your activity :-
recyclerView.setNestedScrollingEnabled(false);

RecyclerView items inside BottomSheetDialogFragment need double touch after fast scrolling

I have a RecyclerView inside BottomSheetDialogFragment. The RecyclerView items touch working normally when it's scrolling slowly.
But when the RecyclerView is scrolled fast and after the list stops (without touching), than touching on any item doesn't work on fast touch. It needs double touching.
See in the below example gif, when touching on Andhra Pradesh it's working fine. After slow scrolling, touching on Haryana also works fine. Then doing a fast scroll and touching on Punjab doesn't work on the first touch. Touching again it works.
Following is the code:
OperatorListDialogFragment.java
package com.*;
import *;
public class OperatorListDialogFragment extends BottomSheetDialogFragment{
private static final String ARG_NAME = "item_name";
private static final String ARG_LOGO = "item_logo";
private Listener mListener;
private String header;
private Context mContext;
public static OperatorListDialogFragment newInstance(String[] name, int[] logo, String header) {
final OperatorListDialogFragment fragment = new OperatorListDialogFragment();
final Bundle args = new Bundle();
args.putStringArray(ARG_NAME, name);
args.putIntArray(ARG_LOGO, logo);
args.putString("header", header);
fragment.setArguments(args);
return fragment;
}

headerTV.setText(getArguments().getString("header"));

recyclerView.setLayoutManager(new LinearLayoutManager(getContext()));
recyclerView.setAdapter(new OperatorAdapter(getArguments().getStringArray(ARG_NAME), getArguments().getIntArray(ARG_LOGO)));

Bug in recycle grid. Changing UI without click randomly

I have a recycler inside fragment in view pager.
The problem that it put likes on user accounts in UI randomly but in DB everything is fine.
In logs, I see that random is not influence on BD. So the bug is only in UI part. After the refresh of the list, it can appear again and after that disappear.
I would like to share code but I already don't have an I idea where the problem could be. It might be in adapter/refresh list listener / XML or any other places. Please let me know what part of the code you need and I will provide it. Maybe it is a bug of recycler as itself and I can't fix it.

Firebase RecyclerView expandable view not working (Do not wish to use any 3rd Party Library)

I have used a FirebaseRecyclerAdapter in my application for displaying a series of events. When i select an event form the recycler view it must expand the recycler view item and show me the details and other items of that event such as dates, description and others. I used a concept from Google I/O 2016 but could't land anywhere as my event is not showing only. I want only a specific set of items to be displayed when expanded.
EventView.java
public class EventView extends AppCompatActivity {
DatabaseReference databaseReference;
RecyclerView recyclerView;
int mExpandedPosition = -1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_event_view);

Android RecyclerView and CardView LayoutManager always crash in Fragment

my app always crash,i try to access a fragment that displays a cardview using RecyclerView.
Here is my Fragment
public class Fragmentone extends Fragment {
private RecyclerView recyclerView;
private List<TestBean> listItem;
private RecyclerAdapter adapter;
public Fragmentone() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_fragmentone, container, false);
recyclerView = (RecyclerView) view.findViewById(R.id.recyclerview);
initData();
adapter = new RecyclerAdapter(listItem,getActivity());
LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity());
recyclerView.setHasFixedSize(true);
layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
recyclerView.setLayoutManager(layoutManager);
recyclerView.setAdapter(adapter);
return view;
}
private void initData() {
listItem = new ArrayList<>();
listItem.add(new TestBean("佛山傻逼酒店","二月17号","二月18号","600","已付款"));
}
}
and this is my adapter
public class RecyclerAdapter extends RecyclerView.Adapter<RecyclerAdapter.ListViewHolder> {

Edit text items are being overlapped in recyclerview

The problem is each and every time when I send the edittext field from pressing save button I think the items are being overlapped or it may be every time i add the values from edit text field old one may be replaced by new values.They are not appearing in the list.
This is the class from where i send the edit text fields
public class MyEditor extends AppCompatActivity {
EditText textIn,txtHeading;
Button buttonAdd,btnsave;
ArrayList<String> nameList = new ArrayList<String>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.editor);
txtHeading = (EditText)findViewById(R.id.heading);
buttonAdd = (Button)findViewById(R.id.add);
btnsave =(Button) findViewById(R.id.btn_save);
btnsave.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String newName = txtHeading.getText().toString();
Intent intent = new Intent(getApplicationContext(),BuilderPage.class);
intent.putStringArrayListExtra("key", nameList);
nameList.add(newName);
int listsize = nameList.size();
for (int i=0;i<listsize;i++){
Log.i("Lists are", nameList.get(i)) ;
}
startActivity(intent);
Toast.makeText(MyEditor
.this,"You added" +newName.toUpperCase()+ "in your view",Toast.LENGTH_LONG).show();
}
});
}
}
This is my Layout that contains RecyclerView.

public void onClick(View v) {

if(listener != null){

}
}}

You are using same textitemname everytime.change
#Override
public void onBindViewHolder(RecyclerViewAdapter.ItemHolder holder, int position) {
holder.setItemName(itemsName.get(position));
}
to
#Override
public void onBindViewHolder(RecyclerViewAdapter.ItemHolder holder, int position) {
holder.textItemName.setText(itemsName.get(position));
}
