Android combined preference

Question

My desired preference order looks very similar to leaving the EditTextPreference box, only that it behaves like a “split button” that combines two settings: if the user clicks on the text on the left, a text editing dialog box appears; which allows the user to set a “label” for preference; if the user clicks the button on the right, another window appears that allows the user to set a “date” for preference.

I suppose I can extend EditTextPreference, but I'm not sure how I can support two separate keys for one preference control (or “widget” in Android terms). Or can you "confuse" two settings without a subclass?

Indeed, you do not need to use the built-in widgets to control your preferences; for example, in my application, I use PreferenceScreen to bring up a multi-choice dialog box with a custom list / adapter. If you want to process your own key / value store, you can bind the preference using the findPreference () method, set the value to PreferenceActivity onCreate (), and store the value in onPause () activity. Exploring the key / value store of preferences can be done using getSharedPreferences (file, MODE.PRIVATE) and the associated retrieval method. To edit them, take the returned SharedPreferences object and call edit () / commit () after changing it.
