    <p>In short, I'm working on a "DurationPickerDialog" that works similarly to how the DatePickerDialog works but works based on the <a href="http://www.w3.org/TR/2001/REC-xmlschema-2-20010502/#duration" rel="nofollow noreferrer">xsd:duration</a> type, so the user specifies the number of years, months, days, etc.</p> <p>I've also implemented a "fuzzy duration" function that gives me durations as a string like "one month ago". I would really like to be able to update the DurationPickerDialog's title in the same manner that the DatePickerDialog's title is updated, but there seems to be a problem. In the DatePickerDialog, they have it set to be a single line all the time, so that it doesn't get "jumpy." Here's how Android's source does the DatePickerDialog's title.</p> <pre><code>// Note: before the skim-readers look at this bit, realize that this is NOT my // code but Android's internal code for the DatePickerDialog. @Override public void show() { super.show(); /* Sometimes the full month is displayed causing the title * to be very long, in those cases ensure it doesn't wrap to * 2 lines (as that looks jumpy) and ensure we ellipsize the end. */ TextView title = (TextView) findViewById(R.id.alertTitle); title.setSingleLine(); title.setEllipsize(TruncateAt.END); } </code></pre> <p>Unfortunately, I cannot access their <code>R.id.alertTitle</code>, because it is part of <code>com.android.internal.R</code>. </p> <p>I have seen implementations like <a href="https://stackoverflow.com/questions/3578929/android-how-to-create-a-dialog-with-a-scrolling-title">this stackoverflow post</a> where it would have me modify the <code>Window.FEATURE_CUSTOM_TITLE</code> attribute, but that doesn't seem to let me modify the title (easily) after that.</p> <p>There was also <a href="https://stackoverflow.com/questions/820398/android-change-custom-title-view-at-run-time">another stackoverflow post</a> that mentioned how to change the title at runtime between two different XML layouts, but that also doesn't seem like it would be all too helpful, since the title should be modified every time the duration changes, and creating an XML layout for each duration is obviously not a good idea.</p> <p>So, since they "cheated" by accessing a value that us mere mortals don't have access to, is there another way that I could go about doing it?</p> <hr/> <p><strong>Edit:</strong> And through some black magic, it seems that it now <em>does</em> ellipsize the text like I was wanting? Only earlier it wasn't, and now I can't seem to reproduce the problem. So, I suppose while we're at it, can someone explain to me how I might have accomplished this magic?</p>

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.
