multiple dependency in checkboxpreference android or listpreference's dependency

Question

For example: i have three checkboxes in my preference screen and there is 3 different listpreference(A,B,C) depended on each checkbox. i want to make the user select only one checkbox at a time. How do i achieve this?

1. There is no radio button in preference screen

2. I can not use Listpreference , if i can use it

     ListPreference
       android:key="livewallpaper_testpattern"
       android:title="@string/livewallpaper_settings_title"
       android:summary="@string/livewallpaper_settings_summary"
       android:entries="@array/livewallpaper_testpattern_names"
       android:entryValues="@array/livewallpaper_testpattern_prefix"
   

Array of this Listprefrence is "blue"," red", "white"

if it is blue ListPreference A depends on blue

if it is red ListPreference B depends on red

if it is white ListPreference C depends on white

How can i do this?

i searched 3-4 pages in google and here almost everything about these but i could not find any answer.

Best Regards,

Thanks in advance..

You can override onSharedPreferenceChanged in your PreferenceActivity class and enable/disable appropriated Preferences programmatically:

public class MyPreferences extends PreferenceActivity implements OnSharedPreferenceChangeListener {
    ...
    public void onSharedPreferenceChanged(SharedPreferences sharedPreferences, String key) {
        if (key.equals("livewallpaper_testpattern")) {
            if (/* check if livewallpaper_testpattern equals to blue */) {
                findPreference("ListPreferenceKey_A").setEnabled(true);
                findPreference("ListPreferenceKey_B").setEnabled(false);
                findPreference("ListPreferenceKey_C").setEnabled(false);
            } else if (/* check if livewallpaper_testpattern equals to red */) {
                // enable B, disable A & C
            } else if (/* check id livewallpaper_testpattern equals to white */) {
                // enable C, disable A & B
            }
        }
    }
