Excellent code!
I found it while trying to get rid of my Lint Warnings for “unused” custom attributes.
Fell into a nasty little trap with the namespace because of an article on stackoverflow.com recommending

1	xmlns:app="http://schemas.android.com/apk/res/com.mycompany.projectname"

as a namespace in Java file and corresponding XML file, which results in an immediately crash. While

1	xmlns:app="http://com.mycompany.projectname"

works fine.
Any ideas how this namespace tying Java code and XML stuff together really works?

Bests,
Tobias

I have some kind problems with the seek bar, when touch on thumb to change value it disappears, when I release my finger it appears….
Also seek bar is “GONE”, when I have more then one element in preference category..
How to solve this?

activity android:theme=”@android:style/Theme.Dialog

- Sorry that got culled out I guess, had to remove the opening less-than sign.

Found two issues with this great code, thank you for that btw…

I’m using this in a preference activity, and in the androidmanifest.xml I declare a theme for the preference activity . This causes the seek bar to not display. Anyone else encounter this?

Also, another issue is the text and summary are not matching the default device theme colors, would be nice to have.

Thanks again!

Hmm, I’m not sure why that would be. I’m fetching the value in my app without any problems, but I’m not setting it outside the PreferenceActivity. Let me know if you find the issue.

Thanks for the info! I haven’t seen that happen, but it probably depends on what your listener is doing. I’ve swapped the order as you suggested, since it should be safer.

Thanks for writing this up in such detail — I learned a lot from it. I made a similar SeekBar in one of my projects and found that it ran fine in the android virtual device launched from Eclipse, but when I actually ran it on my phone, the app would crash as soon as I pressed the menu item that started up the Preferences screen. I fixed this issue by inverting the order of two lines in the initPreference method of the SeekBarPreference class. Here’s the order that worked for me:

mSeekBar.setMax(mMaxValue – mMinValue);
mSeekBar.setOnSeekBarChangeListener(this);

I am not sure if it works, cause if I use sharedpreferance with the same key in another place in my application it does not give value set within PreferanceActivity. Also if I set value outside PreferanceActivity with shared rpeference editor it doesn’t change value within SeekBarPreference.

I assumed you could just listen for them on the preference, but something seems to be grabbing keystrokes before they get there. I’ll post an update if I figure out how to do it.
