Spinner's currently selected item is repeatedly selected

I would like to have the event occur even when the Spinner's currently selected item is repeatedly selected. For example, if 0 is selected and 0 is selected again, I want to make the event fly again.


```
public class MySpinner extends Spinner{

OnItemSelectedListener listener;

public MySpinner(Context context, AttributeSet attrs)
{
super(context, attrs);
}

@override
public void setSelection(int position)
{
super.setSelection(position);

if (position == getSelectedItemPosition())
{
listener.onItemSelected(null, null, position, 0);
}
}

public void setOnItemSelectedListener(OnItemSelectedListener listener)
{
this.listener = listener;
}
}
```

I used this code to define an extension class. How do you apply this to your existing Spinner?

Below is the current source.

```
public static TextView mTXT_DRS4DL, mTXT_DRS4D_NXT;
public static Spinner mSPI_DRS4DL, mSPI_DRS4D_NXT;
public static ArrayList<String> mLIST_DRS4DL, mLIST_DRS4D_NXT;
public static ArrayAdapter<String> mADAPTER_DRS4DL, mADAPTER_DRS4D_NXT;
private static boolean isFirstSelected = true;
private static String mCheckString = "";

{

mSPI_DRS4DL = PlatMainActivity.instance.findViewById(R.id.spi_DRS4DL);
mLIST_DRS4DL = new ArrayList( Arrays.asList());
mADAPTER_DRS4DL = new ArrayAdapter<>(PlatMainActivity.instance, R.layout.support_simple_spinner_dropdown_item, mLIST_DRS4DL);
mSPI_DRS4DL.setAdapter(mADAPTER_DRS4DL);

mSPI_DRS4D_NXT = PlatMainActivity.instance.findViewById(R.id.spi_DRS4D_NXT);
mLIST_DRS4D_NXT = new ArrayList( Arrays.asList());
mADAPTER_DRS4D_NXT = new ArrayAdapter<>(PlatMainActivity.instance, R.layout.support_simple_spinner_dropdown_item, mLIST_DRS4D_NXT);
mSPI_DRS4D_NXT.setAdapter(mADAPTER_DRS4D_NXT);
}
```

```
public static void Search(String mSearch)
{
String mRemoveName;

if(mSearch.contains("DRS4DL")) {
mRemoveName = mSensorSearch.replaceAll(":DRS4DL", "");
mADAPTER_DRS4DL.add(mRemoveSensorName);
mADAPTER_DRS4DL.notifyDataSetChanged();
}
else if(mSearch.contains("DRS4D-NXT")) {
mRemoveName = mSensorSearch.replaceAll(":DRS4D-NXT", "");
mADAPTER_DRS4D_NXT.add(mRemoveSensorName);
mADAPTER_DRS4D_NXT.notifyDataSetChanged();
}
}
```

```
public static void SensorSpinnerEvent()
{
mSPI_DRS4DL.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

//AbstractDataInterface.SendCmdMessage(mMessage, AbstractDataInterface.SEND_TO_DATA, PlatCmdMessage.MsgTouch.Req.SelRadar, 0);
}

@override
public void onNothingSelected(AdapterView<?> parent) {

}
});

mSPI_DRS4D_NXT.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

if(isFirstSelected)
{
isFirstSelected = false;
} else {
switch (position) {
case 0:
mCheckString = mLIST_DRS4D_NXT.get(0);
Log.e("LOG", "---------------------------------------------------->> DRS4D_NXT Check String : " + mCheckString);
break;

case 1:
mCheckString = mLIST_DRS4D_NXT.get(1);
Log.e("LOG", "---------------------------------------------------->> DRS4D_NXT Check String : " + mCheckString);
break;

case 2:
mCheckString = mLIST_DRS4D_NXT.get(2);
Log.e("LOG", "---------------------------------------------------->> DRS4D_NXT Check String : " + mCheckString);
break;
}
}
}

@override
public void onNothingSelected(AdapterView<?> parent) {

}
});
}
```
