[android-developers] How to active the other item in PreferenceActivity’XML

 

Hi,

Following is my XML for PreferenceActivity to use.

 

<PreferenceCategory android:title=" Settings" >

                <CheckBoxPreference android:key="key1"

                        android:title="key1 test"

                        android:defaultValue="false"

                        android:summary="This is the key1" />

               

                <ListPreference android:key="key2"

                        android:entries="@array/sentries"

                        android:title="key2 setting"

                        android:summary="This is the key2"

                        android:defaultValue="0"

                        android:enabled = "false"

                        android:selectable="false"

                        android:entryValues="@array/svalues">

                </ListPreference>

 

</PreferenceCategory>

 

 

When the user clicks the key1 to 'true' , the key2 will be active for use. Otherwise key2 will keep in not selectable.

Can anyone tell me how doing it?
