Android掩藏Preference与PreferenceGroup

属性布局文件test.xml

<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">  	<PreferenceCategory   android:key="base"  android:title="test">      		<CheckBoxPreference  android:key="sub01" /> 		<CheckBoxPreference  android:key="sub02" /> 	</PreferenceCategory></PreferenceScreen>

隐藏Preference与PreferenceGroup

PreferenceGroup base = ((PreferenceGroup) findPreference("base"));Preference sub01 = findPreference("sub01");

隐藏Preference:

base.removePreference(sub01); 

如果需要隐藏PreferenceGroup整个组的话包括sub01和sub02

base.removeAll()；
