A Preference that shows a Dialog with a SeekBar widget.
This Preference is based on support library preference-v7.
In your PreferenceFragmentCompat, override onDisplayPreferenceDialog(Preference) as follows:
@Override
public void onDisplayPreferenceDialog(Preference preference) {
if (!SeekBarPreference.onDisplayPreferenceDialog(this, preference)) {
super.onDisplayPreferenceDialog(preference);
}
}This SeekBarPreference is written according to EditTextPreference implementation, and can be used in a similar way.
Attributes set in XML can also apply to the SeekBar in the dialog.
For instance, you can specify android:max in XML to set the maximum value for the SeekBar.
You can also get and customize the SeekBar that will appear in the Dialog by calling SeekBarPreference.getSeekBar().
The summary of SeekBarPreference is optionally formatted with its progress and max. You can also subclass it and use SeekBarPreference.getRawSummary() to format with your custom information.
