I have an activity where I want to search matching values in my firebase database. I don't want anything to appear up until something is typed on my SearchBar, after something has been typed I want to display values that match what was typed in my SearchBar. I have created an activity and it is not displaying anything up until you type something, my problem is that it does not retrieve the matching values but it shows everything within my database directory.
This is my activity:
public class MyUsersActivity extends AppCompatActivit {
private Toolbar toolbar, searchtollbar;
private RecyclerView mUsersList;
private DatabaseReference mUsersDatabase;
private LinearLayoutManager mLayoutManager;
Menu search_menu;
MenuItem item_search;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_search);
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
//getSupportActionBar().setTitle("Search Users");
//toolbar.setTitleTextColor(android.graphics.Color.WHITE);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
mUsersDatabase = FirebaseDatabase.getInstance().getReference().child("Users");
mLayoutManager = new LinearLayoutManager(this);
mUsersList = (RecyclerView) findViewById(R.id.users_list);
mUsersList.setHasFixedSize(true);
mUsersList.setLayoutManager(mLayoutManager);
setSearchtollbar();
}
@Override

super.onStart();
}
public static class UsersViewHolder extends RecyclerView.ViewHolder {
View mView;
public UsersViewHolder(View itemView) {
super(itemView);
mView = itemView;
}
public void setDisplayName(String name){
TextView userNameView = (TextView) mView.findViewById(R.id.user_single_name);
userNameView.setText(name);
}
public void setUserStatus(String status){
TextView userStatusView = (TextView) mView.findViewById(R.id.user_single_status);
userStatusView.setText(status);
}
public void setUserImage(String thumb_image, Context ctx){

Picasso.with(ctx).load(thumb_image).placeholder(R.drawable.my_profile).into(userImageView);
}

How can I implement the match function to retrieve what's matching in my database?
