onCheckedChanged called automatically

I have a switch in a recyclerview and data is displayed in the recyclerview after retrieving data from DB. When the recyclerview is opened I read DB and if a field in DB is "Y" I enable the switch or else I disable the switch. Now the problem is along with it the onCheckedchanged listener is also called, I want the onCheckedChanged to be called only when user sets the switch manually.

On opening the recyclerview below is executed:

holder.enabledisable.setChecked(messengerRecord.get_is_valid().equalsIgnoreCase("Y"));

ViewHolder class:

public class viewHolder extends RecyclerView.ViewHolder implements CompoundButton.OnCheckedChangeListener{
public SwitchCompat enabledisable;
 public viewHolder(View v) {
            enabledisable = (SwitchCompat) v.findViewById(R.id.enabledisable);
            enabledisable.setOnCheckedChangeListener(this);
...................................
...................................

OncheckedChanged method which is called when the recyclerView is just opened:

@Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            Log.v("ranjith","called oncheckedchanged");
            MessengerRecord rec;
            rec = dbHelper.getRecord(descview.getText().toString());
            switch (buttonView.getId()) {
                case R.id.enabledisable:
                    if (isChecked) {
                        rec.set_is_valid("Y");
                        dbHelper.updateRecord(rec);
                     }
}

In Layout file:

<android.support.v7.widget.SwitchCompat
    android:layout_marginRight="16dp"
    android:layout_marginEnd="16dp"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:focusable="false"
    android:id="@+id/enabledisable"
    android:layout_alignRight="@+id/textview_to"
    android:layout_alignEnd="@+id/textview_to"
    android:layout_alignParentRight="true"
    android:layout_alignParentEnd="true"/>

It's weird all of us have this problem but not official Google answer to this simple problem.

The MOST simple it's to check:

buttonView.isPressed()

If true, means the user clicked the view.

No global variables needed.

Hope this helps.
