Is possible to change the summary of EditTextPreference dynamically in Android?
I set up a preferenceScreen to edit the settings in my application. I would like to insert an EditTextPreference that contains a Title like "set your name" and a summary containing the name开发者_如何学Python entered.
Is that possible? thank you in advance!
Sure, here is a short example:
EditTextPreference etp = (EditTextPreference) findPreference("the_pref_key");
etp.setSummary("New summary");
This requires that you display your preferences either from a PreferenceActivity
or from a PreferenceFragment
, since findPreference()
is a method of these classes. You most likely do that already.
To change the summary every time the user changes the actual preference, use a OnPreferenceChangeListener
and check if the relevant key changed in the callback.
After it has changed, just edit the summary like above.
