How to change text color of preference category in Android?

Question

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

Answer 1

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.

Answer 2

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

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">

Answer 4

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>

Answer 5

An easy way to do this is to set the custom layout for the preferenceCategory here:

<PreferenceCategory
    android:layout="@layout/preferences_category"
    android:title="Privacy" >

Then set your code inside your preferences_category layout file:

<TextView
    android:id="@android:id/title"
    android:textColor="@color/deep_orange_500"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:textSize="16sp"
    android:textStyle="bold"
    android:textAllCaps="true"/>

Answer 6

Inspired by @AliSh answer, but I needed to only change the colour of one Preference text item. So, for all the Kotlin guys out there:

class TextColorPreference : Preference {

    constructor(context: Context) : super(context)

    constructor(context: Context, attrs: AttributeSet) : super(context, attrs)

    constructor(
        context: Context, attrs: AttributeSet,
        defStyle: Int
    ) : super(context, attrs, defStyle)

    override fun onBindViewHolder(holder: PreferenceViewHolder?) {
        super.onBindViewHolder(holder)

        context?.let {
            (holder?.findViewById(android.R.id.title) as? TextView)?.setTextColor(
                ContextCompat.getColor(
                    it,
                    R.color.colorPrimary
                )
            )
        }
    }
}

And then put it in your xml/prefs.xml:

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">

    <this.should.be.your.package.TextColorPreference
        android:id="@+id/settings_logout"
        android:key="@string/prefs_key_logout"
        android:title="@string/settings_logout" />
</PreferenceScreen>
