Setting a spinner onClickListener() in Android

Question

I'm trying to get an onClickListener to fire on a Spinner, but I get the following error:

Java.lang.RuntimeException is "Don't call setOnClickListener for an AdapterView. You probably want setOnItemClickListener instead,"

I'm sure I want to call onClickListener and NOT onItemClickListener. I found a question asked by someone else on Stack Overflow, Is there a way to use setOnClickListener with an Android Spinner?

The answer stated there is:

You will have to set the Click listener on the underlying view (normally a TextView with id: android.R.id.text1) of the spinner. To do so:

Create a custom Spinner In the constructor (with attributes) create the spinner by supplying the layout android.R.layout.simple_spinner_item Do a findViewById(android.R.id.text1) to get the TextView Now set the onClickListener to the TextView

I have tried the answer noted there, but it doesn't seem to work. I get a null pointer to the TextView after I do the findViewById().

This is what I'm doing:

Spinner spinner = (Spinner) findViewById(R.id.spinner);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,R.layout.layoutspinner,dataArray);

spinner.setAdapter(adapter);

TextView SpinnerText = (TextView)findViewById(R.id.spinnerText);
if (SpinnerText == null) {
    System.out.println("Not found");
}
else {
    SpinnerText.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View arg0) {
            //Do something
        }
    });
}

File layoutspinner.xml

<?xml version="1.0" encoding="utf-8"?>
<TextView
    xmlns:android="http://schemas.android.com/apk/res/android"
                  android:id="@+id/spinnerText"
                  android:singleLine ="true"
                  android:layout_width="fill_parent"
                  android:layout_height="wrap_content"
                  android:textSize="6pt"
                  android:gravity="right"/>

What am I doing wrong?

I'm new to Stack Overflow, I didn't find any way to post an aditional question to the other thread (or comment since I have to little rep) so I started a new question.

Per recomendation I tried this:

int a = spinnerMes.getCount();
int b = spinnerMes.getChildCount();
System.out.println("Count = " + a);
System.out.println("ChildCount = " + b);
for (int i = 0; i < b; i++) {
    View v = spinnerMes.getChildAt(i);
    if (v == null) {
        System.out.println("View not found");
    }
    else {
        v.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //Click code
            }
        });
    }
}

But LogCat isn't showing promising results.

10-14 16:09:08.127: INFO/System.out(3116): Count = 7
10-14 16:09:08.127: INFO/System.out(3116): ChildCount = 0

I have tested this on API levels 7 and 8 with the same results.

Answer 1

Personally, I use that:

    final Spinner spinner = (Spinner) (view.findViewById(R.id.userList));
    spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {                

            userSelectedIndex = position;
        }

        @Override
        public void onNothingSelected(AdapterView<?> parent) {
        }
    });
