POSetting a spinner onClickListener() in Android

Body
copied!<p>I'm trying to get an onClickListener to fire on a Spinner, but I get the following error:</p> <blockquote> <p>Java.lang.RuntimeException is "Don't call setOnClickListener for an AdapterView. You probably want setOnItemClickListener instead,"</p> </blockquote> <p>I'm sure I want to call onClickListener and NOT onItemClickListener. I found a question asked by someone else on Stack Overflow, <em><a href="https://stackoverflow.com/questions/3523078">Is there a way to use setOnClickListener with an Android Spinner?</a></em></p> <p>The answer stated there is:</p> <blockquote> <p>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:</p> <p>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</p> </blockquote> <p>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().</p> <p>This is what I'm doing:</p> <pre><code>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 } }); } </code></pre> <h3>File layoutspinner.xml</h3> <pre><code><?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"/> </code></pre> <p>What am I doing wrong?</p> <p>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.</p> <p>Per recomendation I tried this:</p> <pre><code>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 } }); } } </code></pre> <p>But <a href="https://sites.google.com/site/androidhowto/how-to-1/save-logcat-to-a-text-file" rel="noreferrer">LogCat</a> isn't showing promising results.</p> <pre><code>10-14 16:09:08.127: INFO/System.out(3116): Count = 7 10-14 16:09:08.127: INFO/System.out(3116): ChildCount = 0 </code></pre> <p>I have tested this on API levels 7 and 8 with the same results.</p>
