listview wih item click listener fetch wrong data in searchview

when i fetch data from firebase to listview with a itemclicklistener and its working fine,
But when i add a searchview to the listview, Searchview will fetch the itementer image description here but the itemclicklistener showing a wrong result (its showing its position), Please help.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btMenu = findViewById(R.id.btMenu);
sr_txt = findViewById(R.id.sr_txt);
listView = findViewById(R.id.listView);
databaseReference = FirebaseDatabase.getInstance().getReference("dreamapp");
dream1 = new Dream();
title_list = new ArrayList<>();
answer_list = new ArrayList<>();
arrayAdapter = new ArrayAdapter<>(this,R.layout.item,R.id.item,title_list);
databaseReference.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(#NonNull DataSnapshot snapshot) {
for (DataSnapshot d:snapshot.getChildren())
{
dream1 = d.getValue(Dream.class);
title_list.add(dream1.getTitle());
answer_list.add(dream1.getAnswer());
}
listView.setAdapter(arrayAdapter);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int i,long id) {
Intent intent = new Intent(MainActivity.this, answer.class);
String p=answer_list.get(i);
intent.putExtra("answer",p);
startActivity(intent);
}
});
}
#Override
public void onCancelled(#NonNull DatabaseError error) {
}
});
sr_txt.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
MainActivity.this.arrayAdapter.getFilter().filter(query);
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
MainActivity.this.arrayAdapter.getFilter().filter(newText);
return false;
}
});
}
And i have passed the answerlist values from firebase to another intent which is given below , where the result is fetching as position number from database which i need as itemsposition.
package com.example.dreamapp;
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.TextView;
public class answer extends AppCompatActivity {
TextView textView1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_answer);
textView1 = findViewById(R.id.answertext);
String answertxt = getIntent().getStringExtra("answer");
textView1.setText(answertxt);
}
}

Hi i have found the solution for this, When i added one more arrayadapter and listview , then i used it it in the searchview then it worked, it get the results if i search the exact words in it,
sr_txt.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
MainActivity.this.arrayAdapter.getFilter().filter(query);
MainActivity.this.arrayAdapter2.getFilter().filter(query);
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
MainActivity.this.arrayAdapter.getFilter().filter(newText);
MainActivity.this.arrayAdapter2.getFilter().filter(newText);
return false;
}
});
And SearchView
sr_txt.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
MainActivity.this.arrayAdapter.getFilter().filter(query);
MainActivity.this.arrayAdapter2.getFilter().filter(query);
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
MainActivity.this.arrayAdapter.getFilter().filter(newText);
MainActivity.this.arrayAdapter2.getFilter().filter(newText);
return false;
}
});
But still i face an issue with searchView, When i search it searches the entire characters from the array, i need a solution if i could search only five characters from it , it will work fine.

How to implement on click in cardview + recycler view with firebase?

I have implemented a cardview along with a recyclerview that fetch data from firebase. I want to implement onclick methods to cards that goes for different activities. How can i add on click method for the cards? Here is my mainactivity.
public class English extends AppCompatActivity {
ViewHolder apt;
RecyclerView mRecyclerView;
FirebaseDatabase mFirebaseDatabase;
DatabaseReference mRef;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_english);
mRecyclerView = findViewById(R.id.recyclerView);
mRecyclerView.setHasFixedSize(true);
mRecyclerView.setLayoutManager(new LinearLayoutManager(this));
mFirebaseDatabase = FirebaseDatabase.getInstance();
mRef = mFirebaseDatabase.getReference("English");
}
private void firebaseSearch(String searchText){
Query firebaseSearchQuery=mRef.orderByChild("artist").startAt(searchText).endAt(searchText + "\uf8ff");
FirebaseRecyclerAdapter<englishacti, ViewHolder> firebaseRecyclerAdapter=new FirebaseRecyclerAdapter<englishacti, ViewHolder>(englishacti.class,R.layout.row,ViewHolder.class,firebaseSearchQuery) {
#Override
protected void populateViewHolder(ViewHolder holder, englishacti model, int position) {
holder.setDetails(getApplicationContext(),model.getAlbum(),model.getDescription(),model.getImage(),model.getArtist());
}
};
mRecyclerView.setAdapter(firebaseRecyclerAdapter);
}
#Override
protected void onStart() {
super.onStart();
FirebaseRecyclerAdapter<englishacti,ViewHolder> firebaseRecyclerAdapter;
firebaseRecyclerAdapter = new FirebaseRecyclerAdapter<englishacti, ViewHolder>(englishacti.class,R.layout.row,ViewHolder.class,mRef) {
#Override
protected void populateViewHolder(ViewHolder viewHolder, englishacti model, int position) {
viewHolder.setDetails(getApplicationContext(), model.getAlbum(), model.getDescription(), model.getImage(), model.getArtist());
}
};
mRecyclerView.setAdapter(firebaseRecyclerAdapter);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu,menu);
MenuItem item = menu.findItem(R.id.action_search);
SearchView searchView = (SearchView) MenuItemCompat.getActionView(item);
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
firebaseSearch(query);
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
firebaseSearch(newText);
return false;
}
});
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id=item.getItemId();
if (id==R.id.action_settings){
return true;
}
return super.onOptionsItemSelected(item);
}
}

please take a look at my snipshed code, in my case i use this way to implement setonlclick in recycleview item and send value to other activity
holder.setName(userName);
holder.setUserImage(userThumb, getContext());
holder.mView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent chatIntent = new Intent(getContext(), Tampung_chatActivity.class);
chatIntent.putExtra("user_id", list_user_id);
chatIntent.putExtra("user_name", userName);
startActivity(chatIntent);
}
});
full code you can see at here :

Firebase Database is showing after clicking Searchview. How to solve this?

Hi I am using Firebase Database with search query. I am also using offline method to store data from firebase offline. But after implementing searchview when I am opening the page it is showing blank. Data is coming after clicking the search icon. How to solve this? My application is on the playstore. It is the Link of the Application
And Here is my search query Code
private void firebaseUserSearch(String searchText) {
Query firebaseSearchQuery = mUserDatabase.orderByChild("Title").startAt(searchText).endAt(searchText + "\uf8ff");
FirebaseRecyclerAdapter<Blog,BlogViewHolder> firebaseRecyclerAdapter = new FirebaseRecyclerAdapter<Blog, BlogViewHolder>(
Blog.class,
R.layout.bank_row,
BlogViewHolder.class,
firebaseSearchQuery
) {
#Override
protected void populateViewHolder(BlogViewHolder viewHolder, final Blog model, int position) {
final String fav_key=getRef(position).getKey();
viewHolder.setDetails(getApplicationContext(), model.getTitle(), model.getDescription(), model.getExample());
viewHolder.setFavourite(fav_key);
viewHolder.favourite.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
mfavourite=true;
databasefavourite.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
if(mfavourite){
if (dataSnapshot.child(fav_key).hasChild("Title")){
databasefavourite.child(fav_key).child("Title").removeValue();
mfavourite = false;
}else {
databasefavourite.child(fav_key).child("Title").setValue(model.getTitle());
mfavourite = false;
}
if (dataSnapshot.child(fav_key).hasChild("Description")){
databasefavourite.child(fav_key).child("Description").removeValue();
mfavourite = false;
}else {
databasefavourite.child(fav_key).child("Description").setValue(model.getDescription());
mfavourite = false;
}
if (dataSnapshot.child(fav_key).hasChild("Example")){
databasefavourite.child(fav_key).child("Example").removeValue();
mfavourite = false;
}else {
databasefavourite.child(fav_key).child("Example").setValue(model.getExample());
mfavourite = false;
}
}
}
#Override
public void onCancelled(DatabaseError databaseError) {
}
});
}
});
}
};
mResultList.setAdapter(firebaseRecyclerAdapter);
}
It is my code for onStart()
#Override
protected void onStart() {
super.onStart();
FirebaseRecyclerAdapter<Blog,Idioms.BlogViewHolder>firebaseRecyclerAdapter=new FirebaseRecyclerAdapter<Blog, Idioms.BlogViewHolder>
(Blog.class,R.layout.bank_row,Idioms.BlogViewHolder.class,mUserDatabase) {
#Override
protected void populateViewHolder(Idioms.BlogViewHolder viewHolder, final Blog model, int position) {
final String fav_key=getRef(position).getKey();
viewHolder.setDetails(getApplicationContext(), model.getTitle(), model.getDescription(), model.getExample());
viewHolder.setFavourite(fav_key);
viewHolder.favourite.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
mfavourite=true;
databasefavourite.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
if(mfavourite){
if (dataSnapshot.child(fav_key).hasChild("Title")){
databasefavourite.child(fav_key).child("Title").removeValue();
mfavourite = false;
}else {
databasefavourite.child(fav_key).child("Title").setValue(model.getTitle());
mfavourite = false;
}
if (dataSnapshot.child(fav_key).hasChild("Description")){
databasefavourite.child(fav_key).child("Description").removeValue();
mfavourite = false;
}else {
databasefavourite.child(fav_key).child("Description").setValue(model.getDescription());
mfavourite = false;
}
if (dataSnapshot.child(fav_key).hasChild("Example")){
databasefavourite.child(fav_key).child("Example").removeValue();
mfavourite = false;
}else {
databasefavourite.child(fav_key).child("Example").setValue(model.getExample());
mfavourite = false;
}
}
}
#Override
public void onCancelled(DatabaseError databaseError) {
}
});
}
});
}
};
mResultList.setAdapter(firebaseRecyclerAdapter);
}
And it is my search action code
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main_menu, menu);
MenuItem item = menu.findItem(R.id.action_search);
SearchView searchView = (SearchView) MenuItemCompat.getActionView(item);
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
firebaseUserSearch(query);
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
firebaseUserSearch(newText);
return false;
}
});
return super.onCreateOptionsMenu(menu);
}

How do I Query this in Android Studio using Firebase?

In my software I need a Query, how do I Query 2 information from the Database?? I need the "uid" and "book", check the link for watching my Database: https://i.stack.imgur.com/9TSt6.png
listWN = (RecyclerView) findViewById(R.id.listReading);
listWN.setLayoutManager(new LinearLayoutManager(this));
bookYouAreIn = getIntent().getStringExtra("book");
firebaseauth = FirebaseAuth.getInstance();
String currentUserId = firebaseauth.getCurrentUser().getUid();
mDatabase = FirebaseDatabase.getInstance().getReference("Data");
mQuery = mDatabase.orderByChild("book").equalTo(bookYouAreIn); **---> HOW DO I ADD HERE: AND mDatabase.orderByChild("uid").equalTo(firebaseauth.getCurrentUser().getUid());**
mDatabase.keepSynced(true);
if(!firebaseauth.getCurrentUser().getUid().equals(currentUserId)){
startActivity(new Intent(WordNote.this,LoginActivity.class));
finish();
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main_secondmenu, menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if(item.getItemId() == R.id.action_addWords){
Intent postIntent = new Intent(WordNote.this, PostActivity.class);
postIntent.putExtra("bookToPost", bookYouAreIn);
startActivity(postIntent);
}
return super.onOptionsItemSelected(item);
}
#Override
protected void onStart() {
super.onStart();
final FirebaseRecyclerAdapter<MyReading, MyReadingViewHolder> firebaseRecyclerAdapter = new FirebaseRecyclerAdapter <MyReading, MyReadingViewHolder>
(
MyReading.class,
R.layout.list_reading,
MyReadingViewHolder.class,
mQuery )
{
#Override
protected void populateViewHolder(final MyReadingViewHolder viewHolder, final MyReading model, final int position) {
final String wordNote_key = getRef(position).getKey();
viewHolder.setWord(model.getWord());
viewHolder.setNote(model.getNote());
mDatabase.child(wordNote_key).addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
String user = (String) dataSnapshot.child("uid").getValue();
String bookNow = (String) dataSnapshot.child("book").getValue();
if(firebaseauth.getCurrentUser().getUid().equals(user)){
mDatabase.child(wordNote_key).orderByChild("uid").equals(user);
}
else {
viewHolder.nView.setVisibility(View.GONE); **--> IT DOESN'T GO AWAY, IT KEEPS STAYING AS A BLANK VIEW**
}
}
#Override
public void onCancelled(DatabaseError databaseError) {
}
});
viewHolder.nView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent singleIntent = new Intent(WordNote.this, HandleWordNote.class);
singleIntent.putExtra("listWords", wordNote_key);
startActivity(singleIntent);
}
});
}
};
listWN.setAdapter(firebaseRecyclerAdapter);

See my answer from this post.
In your case, the field would be: uid_book: "OKtUxSleCGbU0F_Pasqua".
Hope it helps.

Firebase Android SearchView by values

I have worked for search about how to search in firebase by vaule and I couldn't have a fully answer so I am asking now ...
I have used this method and I couldn't get the correct result:
I need to search by "Username".
Here's my database:
mSearchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
mQuery = mDatabase.orderByChild("Username");
return false;
}
});
And also I have used:
mSearchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
mQuery = mDatabase.orderByChild("Username").equalTo(newText)
return false;
}
});
but I couldn't so can anyone give me fully correct answer please
Thanks AtaerCaner for helping me and also thanks for trying to help me as much as you can, but I still haven't got any result from the Search View so I will give the method that is in my class:
mDatabase.addChildEventListener(new ChildEventListener() {
#Override
public void onChildAdded(final DataSnapshot dataSnapshot, String s) {
mSearchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
String A = (String) dataSnapshot.child(Post_Key).child("Username").getValue();
mQuery = mDatabase.orderByChild(A).equalTo(query);
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
String A = (String) dataSnapshot.child(Post_Key).child("Username").getValue();
mQuery = mDatabase.orderByChild(A).equalTo(newText);
return false;
}
});
}
So Please check the method if its correct or not ..

Let's think i'm searching Mike. First, bring all users by username with mDatabase.child("Users").orderByChild("Username"). But i want the Mike's datas, so i add .equalTo("Mike"). This returns a query as i say then set an .addListenerForSingleValueEvent to get datas of Mike. The information i want will come as iterable object with one item in this callback. Then cast it to your User modal.
mDatabase.child("Users").orderByChild("Username").equalTo("Mike").addListenerForSingleValueEvent(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
User user = dataSnapshot.getChildren().iterator().next().getValue(User.class);
}
#Override
public void onCancelled(DatabaseError databaseError) {
}
});
As far as i see in your code you get the query with mQuery = mDatabase.orderByChild(A).equalTo(newText) but you don't do anything with it.
Maybe this guy can help you
