You should set OnclickListener inside ViewHolder and get clicked Item's posision with getLayoutPosition() method.
public class ContactsViewHolder extends RecyclerView.ViewHolder {
TextView txt_contactname;
TextView txt_contactName;
TextView txt_contact_no;
LinearLayout linearLayout;
SwitchCompat switchBlock;
TextView txtno;
public ContactsViewHolder(View itemView) {
super(itemView);
this.txtno = (TextView) itemView.findViewById(R.id.txtno);
this.txt_contactname = (TextView) itemView.findViewById(R.id.txt_contactName);
this.txt_contactName = (TextView) itemView.findViewById(R.id.txt_contact_name);
this.txt_contact_no = (TextView) itemView.findViewById(R.id.txt_contact_no);
this.linearLayout = (LinearLayout) itemView.findViewById(R.id.linearlayout);
this.switchBlock = (SwitchCompat) itemView.findViewById(R.id.switchButton_block);
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int position =getLayoutPosition();
//Your logic
}
});

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.
I've a custom list view with 4 textViews and 2 buttons,which i am filling up via database,
TV NAME | TV EMAIL | TV NO | TV ID(database primary key,set invisible) | ButtonEDIT | ButtonDelete.
I successfully got the id from the database,which is set as primary key.
Now what i want to do is,when i PRESS ButtonEDIT,it should toast a message something like
"Edit selected for ID :" + TVID.getText().toString(),so basically i want to display the value which is stored in the TVID(i.e. my database id).
But when i am trying to do it,it only displays the firstID (0) for buttons of different rows,please do help asap.

Try adding this to your adapter:
public class MyAdapter extends BaseAdapter
{
public static HashMap<Integer,String> myList=new HashMap<Integer,String>();
...
#Override
public View getView(final int position, View convertView, ViewGroup parent)
{
...
myList.put(position,String.valueOf(data.get(position).getID()));
return convertView;
}
...
}
Now in your activity,
public class viewnameactivity extends Activity
{
...
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent,View v,int position,long id) {
pos = adapter.getUserArray(position);
String TVID=MyAdapter.myList.get(position); // this will give you tvid for each listitem
}
});
...
}
How can i get image from image url in image view.
My imageUrl is coming from databaseadapter.
In Fields class LocationImage dataype is string but in setBackgroundResource method it is asking for int value as parameter. LocationImage url is getting from database, so that i've taken that as string variable.
