How to customize CheckBoxPreference header text color

Question

How to change header text color in CheckBoxPreference?

Answer 1

As zenob said, this can be solved with a custom layout. The application uses the preferences layout defined in the structure:

custom_preferece_layout.xml

The Preference is able to place a specific widget for its particular type in the "widget_frame" layout. --> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="wrap_content" android:minHeight="?android:attr/listPreferredItemHeight" android:gravity="center_vertical" android:paddingRight="?android:attr/scrollbarSize"> <RelativeLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="15dip" android:layout_marginRight="6dip" android:layout_marginTop="6dip" android:layout_marginBottom="6dip" android:layout_weight="1"> <TextView android:id="@+android:id/title" android:layout_width="wrap_content" android:layout_height="wrap_content" android:singleLine="true" android:textAppearance="?android:attr/textAppearanceLarge" android:ellipsize="marquee" android:fadingEdge="horizontal" android:textColor="#FF0000" /> <TextView android:id="@+android:id/summary" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@android:id/title" android:layout_alignLeft="@android:id/title" android:textAppearance="?android:attr/textAppearanceSmall" android:maxLines="4" /> </RelativeLayout> <!-- Preference should place its actual preference widget here. --> <LinearLayout android:id="@+android:id/widget_frame" android:layout_width="wrap_content" android:layout_height="match_parent" android:gravity="center_vertical" android:orientation="vertical" /> </LinearLayout> 

the textColor attribute is defined for the TextView header in the above layout. Use this layout with checkbox preference in xml preference.

mypreference.xml

 <?xml version="1.0" encoding="utf-8"?> <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"> <CheckBoxPreference android:key="testcheckbox" android:title="Checkbox Title" android:summary="Checkbox Summary..." android:layout="@layout/custom_preference_layout"></CheckBoxPreference> </PreferenceScreen> 

The flag preference header will have the color defined in the custom layout.

One simple solution I found is to add this to your style

  <item name="android:textColorSecondary">#000000</item> <item name="android:textColorPrimary">#000000</item> 

textColorPrimary will change the color of the name checkBoxPreference and textColorSecondary will change the color of summary .

You open the color.xml file and change it to Light Blue # 4096ff:

 <color name="colorAccent">#4096ff</color>

Unfortunately, you cannot access the CheckBoxPreference layout - it is declared in the internal package.

You can create your own preferences using a custom layout.
