multiple items get selected automatically when i select one item in recyclerview
What i m doing is
i just want to fetch contacts with no duplication and list all contacts in recyclerview And make visible two textviews (one is for number and second is for name)Its Done But The problem is
when i click on an item it gets clicked 4 times (for example if i click on an item it make visible two textviews but the same item with same name and number get visible like with i have clicked 4 items and see pics )

You should set OnclickListener inside ViewHolder and get clicked Item's posision with getLayoutPosition() method.
public class ContactsViewHolder extends RecyclerView.ViewHolder {

I have a sample app where the contacts in my android phone are listed and I can search for them. However, very often the contacts are listed twice. I only want them to be listed once. What should I change in my code to fix this? I've posted the relevant parts of my code below.
I did try here how to remove duplicate contacts from arraylist but I couldn't modify the code sufficiently to suit my needs.

I am working with GridView. I want to update GridView on some basis. But notifyDataSetChanged() method is not working.
I am selecting tables on basis of section name. When I select section name very first time than I got tables of that section. But when I go to sections fragment again and select diff. section than I get previously selected tables only. That means notifyDataSetChanged() is not working.
What I have tried is like below.

At last I got the solution.
I have done like below...
I was maintaining a FLAG called getTableStatus to get the tables of particular section. If the value of getTableStatus is FALSE than only TableStatusAsync is called. At first selection of section, tables are coming from web service and those tables are being inserted in DB.
On second time, selecting of SECTION, tables are coming from DB not from web service. And tables are coming from DB are of previously selected SECTION. So, there is nothing to do with notifyDataSetChanged().
I have just change the FLAG value to FALSE by calling pref.setTableStatus(false); on selection of SECTION. Now, TableStatusAsync is called every time when you change your selection of SECTION.
Modified Code...
TableScreenSectionwiseActivity.java
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
pref.setSectionId(view.getTag().toString());
pref.setTableStatus(false);
pref.setTableServiceStatus(false);
Fragment fragment = new TableScreenActivity();
ReplaceFragment.getReplaceFragment(getActivity(), fragment, "");
}

I have created a custom Adapter for list which different items and each item has a button to invite. The item should flip horizontally when the respective invite button is clicked and that is working fine. The problem is that when I click invite button of first item then invite button of 4th item is also clicked. I am attaching the code hee

The View objects are recycling and you're using the same ViewHolder object (and other UI components) for both positions. The view being clicked has had its tag updated to the position desired, but the animation object is the same as another position due to the recycling.

AS i am new to android, i am not sure if the above code to check for user selection of checkboxes should be done in which section of the fragment? I would actually like to populate this data if the user has selected the Done menu presented on the top right corner but then i am finding it difficult to spend the sparse boolean array from fragment to activity. Is there a way this can be accomplished?
Adding code for the main activity which has the "Done" menu button:
package com.project.iandwe;
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.view.ViewPager;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.widget.Toast;
import com.project.iandwe.Adaptor.FragmentContactAdaptor;
import com.project.iandwe.Adaptor.UserDatabaseAdapter;
/**

public class AddContacts extends FragmentActivity {
ViewPager viewPager = null;
String name;
String eventId,description,date, time, location;
protected void onCreate( Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.add_contacts);
viewPager = (ViewPager) findViewById(R.id.pager_contacts);
FragmentManager fragmentManager = getSupportFragmentManager();
viewPager.setAdapter(new FragmentContactAdaptor(fragmentManager));
//viewPager.setCurrentItem(1);
Intent intent = getIntent();
eventId = intent.getExtras().getString("eventId");
name = intent.getExtras().getString("name");
description = intent.getExtras().getString("description");
date = intent.getExtras().getString("date");
time = intent.getExtras().getString("time");
location = intent.getExtras().getString("location");
}
public boolean onCreateOptionsMenu(Menu menu){
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.add_event_finish,menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_finish:
//UserDatabaseAdapter userDatabaseAdapter = new UserDatabaseAdapter(this);
//long id = userDatabaseAdapter.insertUserEvent(name,description,date,time,location);
//if (id>0 ) {
Toast.makeText(this,"Event successfully Created",Toast.LENGTH_LONG).show();
Intent intent = new Intent(this, HomePage.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(intent);
finish();
// }
return true;
default:
return super.onOptionsItemSelected(item);
}
}
}
In the menu done handler try to get your adapter in this way:
ContactsFragments fragment = (ContactsFragments) getSupportFragmentManager()
.findFragmentByTag("ContactsFragments");
ListView listView = fragment.listView;
ContactSelectAdaptor adapter = (ContactSelectAdaptor)listView.getAdaptor();
If you have the adaptor then your sparseb boolean array is visible.
