Question

I need check a value and enable or disable programatically “checkboxpreference”. I using this code but getPreferenceScreen() wants a method and I don’t know which method use. (I use this on android 2.1).

                        <CheckBoxPreference
                        android:enabled="true"
                        android:title="Now"
                        android:defaultValue="false"
                        android:key="keep" />



protected void check(){

        // read values

        if (values){
getPreferenceScreen().findPreference("checkbox-preference-key").setEnabled(true);
        }
        else {
getPreferenceScreen().findPreference("checkbox-preference-key").setEnabled(false);

Answer 1

Use getPreferenceManager() instead.

So your code now looks like:

getPreferenceManager().findPreference("keep").setEnabled(values);

This is the equivalent of

if (values){
  getPreferenceManager().findPreference("keep").setEnabled(true);
}
else {
  getPreferenceManager().findPreference("keep").setEnabled(false);
}
