I have CheckBoxPreference and 2 others: one is Edit Test Pref. and another is ListBox Pref. How I can enable list box pref and disable edit text pref. when CheckBoxPreference is turned on?

Seems it’s duplicate of this question

You can override public void onSharedPreferenceChanged(final SharedPreferences sharedPreferences, final String key) and when it get called with key.equals(<Your key for setting>) do something like:

boolean isEnabled = sharedPreferences.getBoolean(key, true);
getPreferenceScreen().findPreference("list box preference key").setEnabled(isEnabled);
getPreferenceScreen().findPreference("list box preference key").setEnabled(!isEnabled);

Also, do the same in onCreate() to have Your preferences screen proper initial setup.
