Android Question

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"/>

Answer

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.
