<PreferenceScreen
xmlns:android="http://schemas.android.com/apk/res/android">
<CheckBoxPreference
    android:key="checkBoxenableincomingcall"
    android:title="Enable incoming call"
    android:defaultValue="true"
    android:summary="hasse running as background service" />
<CheckBoxPreference
    android:key="checkBoxmakephoneringonincoming"

public class EditPreferences extends PreferenceActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    addPreferencesFromResource(R.xml.preferences);
}

}

推荐答案

有你的 preferenceActivity 实施在preferenceChangeListener ，然后用它注册您的复选框。当你发现它已被pressed禁用preference

have your PreferenceActivity implement OnPreferenceChangeListener and then register your checkbox with it. When you detect that it has been pressed disable the preference

//in onCreate
findPreference("checkboxpreferencekey").setOnPreferenceChangeListener(this);


public boolean onPreferenceChange(Preference preference, Object newValue){
   if(preference.getKey().equals("checkboxpreferencekey")){
      preference.setEnabled(false);
      return true;
   }
   else return true;
}

这是你可以禁用它，你仍然需要某种形式的回调，或从服务广播知道什么时候再次启用它。但是，当它的时候，你做同样的方式。

That is how you can disable it, you will still need some sort of callback or broadcast from your service to know when to enable it again. But when its time you do it the same way.

findPreference("checkboxpreferencekey").setEnabled(true);
