How to change text color of preference category in

Question

The textColor attribute isn't working. Here's my XML:

<PreferenceCategory
        android:title="Title"
        android:textColor="#00FF00">

Any ideas?

Answer 1

Other way around will be mention the theme in your AppTheme, application level

    <style name="AppBaseTheme" parent="Theme.AppCompat.Light.NoActionBar">
        .....//your other items
        <item name="preferenceTheme">@style/PrefTheme</item>
    </style>

    <style name="PrefTheme" parent="@style/PreferenceThemeOverlay">
        <item name="preferenceCategoryStyle">@style/CategoryStyle</item>
    </style>

    <style name="CategoryStyle" parent="Preference.Category">
        <item name="android:layout">@layout/pref_category_view</item>
    </style>

XML : pref_category_view

<?xml version="1.0" encoding="utf-8"?>
<TextView android:id="@android:id/title"
          style="?android:attr/listSeparatorTextViewStyle"
          xmlns:android="http://schemas.android.com/apk/res/android"
          android:layout_width="match_parent"
          android:textColor="@color/red"
          android:layout_height="wrap_content"
    />

Important: I am using PreferenceFragmentCompat from lib v7 Preference.

One solution is to make a theme for your PreferenceScreen. So in your themes.xml or styles.xml (better to put it in themes.xml) :

<style name="PreferenceScreen" parent="YourApplicationThemeOrNone">
    <item name="android:textColor">@color/yourCategoryTitleColor</item>
</style>

then in your AndroidManifest.xml :

<activity
      android:name="MyPreferenceActivity"
      ...
      android:theme="@style/PreferenceScreen" >
</activity>

It worked perfectly for me.

Answer 3

public class MyPreferenceCategory extends PreferenceCategory {

 public MyPreferenceCategory(Context context) {
    super(context);
    // TODO Auto-generated constructor stub
  }
 public MyPreferenceCategory(Context context, AttributeSet attrs) {
    super(context, attrs);
  }
 public MyPreferenceCategory(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
    // TODO Auto-generated constructor stub
  }

 @Override
 protected View onCreateView(ViewGroup parent) {
    // It's just a TextView!
 TextView categoryTitle =  (TextView)super.onCreateView(parent);
 categoryTitle.setTextColor(parent.getResources().getColor(R.color.orange));

    return categoryTitle;
  }
}

And in your prefs.xml:

<com.your.packagename.MyPreferenceCategory android:title="General">
.
.
.
</com.your.packagename.MyPreferenceCategory>

Define your own PreferenceTheme and override colors.

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="preferenceTheme">@style/AppTheme.PreferenceTheme</item>
</style>

<style name="AppTheme.PreferenceTheme" parent="PreferenceThemeOverlay.v14.Material">
    <item name="colorAccent">`#color_value`</item>
</style>

A lot of the other answers didn't work for my case. I'm using a PreferenceFragmentCompat and I didn't want to have actual code doing this. So I simply made a copy of the preference category xml file and changed the textColor field. The file goes under the Apache license, Version 2.

<?xml version="1.0" encoding="utf-8"?>

  <LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginBottom="8dp"
    android:layout_marginTop="8dp"
    android:layout_marginStart="?android:attr/listPreferredItemPaddingLeft"
    android:orientation="vertical">
    <TextView
      android:id="@android:id/title"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:layout_marginTop="16dp"
      android:paddingEnd="?android:attr/listPreferredItemPaddingRight"
      android:textAlignment="viewStart"
      android:textColor="@color/app_accent"
      android:textStyle="bold"
      tools:ignore="RtlSymmetry"/>
    <TextView
      android:id="@android:id/summary"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:ellipsize="end"
      android:singleLine="true"
      android:textColor="?android:attr/textColorSecondary"/>
  </LinearLayout>

And imported it in my .xml layout for the Preference fragment:

 <PreferenceCategory
    android:layout="@layout/preference_category_companion"
    android:key="my_preference_title"
    android:title="@string/my_preference_title">

To change text color of preference category only set a theme to your PreferenceActivity in your Android Manifest and make sure that colorAccent item exists. This color is taken by your PreferenceCategory.
