    <blockquote> <p>However, when a spinner is clicked, the drop-down list appears at full width and covers the whole table. </p> </blockquote> <p>That is because it is really a pop-up dialog.</p> <blockquote> <p>There must be a way of restricting the width of the list.</p> </blockquote> <p>This is difficult, as you are not the one creating the dialog. I do not even see how you could accomplish this by extending Spinner with your own subclass, given the way <code>Spinner</code> is written. You might have to clone the <code>Spinner</code> source code, move it to another package (or class name), and alter <code>performClick()</code> to change the size of the <code>AlertDialog</code> using the techniques outlined in <a href="https://stackoverflow.com/questions/4406804/how-to-control-the-width-and-height-of-default-alert-dialog-in-android">How to control the width and height of the default Alert Dialog in Android?</a>.</p> <p>And, bear in mind that the behavior of <code>Spinner</code> is significantly different on Honeycomb, and it remains to be seen how it looks on Ice Cream Sandwich. We do not have the Honeycomb source code, so my clone-the-class solution is going to give you problems on newer devices.</p> <blockquote> <p>I have seen a note on R.attr.dropDownWidth which looks as though it may help but I have no idea how to implement this method, let alone if it will actually work.</p> </blockquote> <p>It is not a method, but rather an attribute you could set in a style. However, based on the source code, it appears that this is only used for <code>AutoCompleteTextView</code>'s drop-down.</p>

    1. COHi CommonsWare, Yes, I had come to the same conclusion and am going to leave things as they are. As you say, this situation may be different in later versions but, for now at least, I need to stay backwardly compatible. Thanks anyway. Alan ...

    2. COHaving uploaded onto a different device I notice that the elements of the spinner and the list are quite difficult to select. I had set the textview in the row xml as 'wrap-content' and it meant that, if there were only 1 or 2 characters in the tv, you had to actually hit one of them to select the row. By changing to 'fill_parent' the tv stretches right across the row and makes selection easier. I thought this might help others. Best wishes, Alan ...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
