OK, I have solved the problem myself, through a process of iteration! Others might find this useful. Just create an empty PreferenceScreen in the xml: <pre><code> <PreferenceScreen android:title="Show filters for category" android:summary="Click to choose subjects to delete" android:key="filterShow"> </PreferenceScreen> </code></pre> Then in the code there is no need for the onClick listener - the contents of the screen are created in the onCreate function. Actually, since the contents of the screen need to change when the choice made in the Category list preference (see original code) changes, this needs to go in a separate function which is called both from onCreate and onSharedPreferenceChanged: <pre><code>public static final String KEY_FILTER_SHOW = "filterShow"; ... private PreferenceScreen mFilterShow; ... // In onCreate: // Get a reference to the PreferenceScreen mFilterShow = (PreferenceScreen)getPreferenceScreen().findPreference(KEY_FILTER_SHOW); // Now the code to create the contents of the screen mFilterShow.removeAll(); CheckBoxPreference cb1 = new CheckBoxPreference(this); cb1.setTitle("This is cb1"); cb1.setKey("cb1_key"); cb1.setDefaultValue(true); mFilterShow.addPreference(cb1); </code></pre> The above is just "proof of concept". It works exactly as you would expect. In my final version, I will create an array of CheckBoxPreferences with 'new' initially, then re-use them (changing title and default) when setting up the contents of the screen for each Category choice as it changes. The number of check boxes required may be different for each category - I will create an array for the maximum number required, then add as many as I need in each case.

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.
