copied!<p>I have this bug in my app only on Android 4.4.</p> <p>In the debugger it shows the same message as the question asker.

This is strange, since the code is failing inside a <code>ListAdapter</code>, where you don't supply layout params in <code>getView</code>. </p> <p>I used to inflate <code>android.R.layout.simple_spinner_item</code> for standard spinner items. It looks like this item uses <code>ellipsing</code>. So in my <code>getView</code> I now call:</p> <pre><code>view.setEllipsize(null); </code></pre> <p>This fixes my problems on Android 4.4.</p> <p><strong>Edit</strong></p> <p>It turns out the problem is not the ellipsing, but improper inflating of a view in <code>getView</code>.</p> <pre><code>inflater.inflate(android.R.layout.simple_spinner_item, null);//WRONG inflater.inflate(android.R.layout.simple_spinner_item, parent, false);//GOOD </code></pre> <p>Note that you supply <code>false</code> to not attach the view immediately to the parent, because this is in a adapter that attaches children when needed. Otherwise you will get errors. </p> <p>When you inflate properly, you don't need to set <code>ellipseSize</code> to <code>null</code>. This is because when you inflate the good way, with a parent, it handles the <code>LayoutParams</code> properly, causing the ellipse code not to raise <code>NullPointerException</code>.</p> <p>So, inflate properly, and then you don't have to worry anymore.</p>
