CustomPreferenceCategory不能转换为android.preference.GenericInflater $ Parent

我做了CustomPreference，它和PreferenceCategory一起工作良好，但是CustomPreferenceCategory有个问题，就像uk.co.bla.bla.customwidget.viewgroup.CustomPreferenceCategory不能转换为android .preference.GenericInflater $父

CustomPreferenceCategory.class

public class CustomPreferenceCategory extends PreferenceCategory { 
private TextView txt; 
public CustomPreferenceCategory(Context context, AttributeSet attrs) { 
    super(context, attrs); 
    this.setWidgetLayoutResource(R.layout.preference_category_title); 
} 


@Override 
protected void onBindView(View view) { 
    super.onBindView(view); 
    txt = (TextView) view.findViewById(R.id.text_view_preference_category_title); 
} 

public void setText(String text, int color) { 
    txt.setText(text); 
    txt.setTextColor(color); 
} 
}

preference_category_title

<android.support.percent.PercentRelativeLayout 
xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:app="http://schemas.android.com/apk/res-auto" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:background="@color/grey_231" 
> 
<TextView 
    android:id="@+id/text_view_preference_category_title" 
    android:layout_width="wrap_content" 
    android:layout_height="32.5dp" 
    android:text="@string/profile_preference" 
    android:textSize="14dp" 
    android:gravity="center" 
    app:layout_marginLeftPercent="3.5%" 
    android:textColor="@color/charcoalGrey_30" 

    /> 
    </android.support.percent.PercentRelativeLayout>

preference.xml

<uk.co.bla.bla.customwidget.viewgroup.CustomPreferenceCategory 
    android:name="uk.co.bla.bla.customwidget.viewgroup.CustomPreferenceCategory" 
    android:key="@string/profile_preference" 
    android:layout="@layout/preference_category_title"> 

    <uk.co.bla.bla.customwidget.viewgroup.CustomPreferenceButton 
     android:name="uk.co.bla.bla.customwidget.viewgroup.CustomPreferenceButton" 
     android:layout="@layout/preference_button" 
     android:key="@string/edit_profil_button_preference"/> 

    <uk.co.bla.bla.customwidget.viewgroup.CustomPreferenceButton 
     android:key="@string/change_password_preference" 
     android:layout="@layout/preference_button"/> 
    </uk.co.bla.bla.customwidget.viewgroup.CustomPreferenceCategory>
