How to change text color of preference category in Android?

Question

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

Answer 1

use this customize PreferenceCategory class :

public class MyPreferenceCategory extends PreferenceCategory {
    public MyPreferenceCategory(Context context) {
        super(context);
    }

    public MyPreferenceCategory(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public MyPreferenceCategory(Context context, AttributeSet attrs,
            int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    protected void onBindView(View view) {
        super.onBindView(view);
        TextView titleView = (TextView) view.findViewById(android.R.id.title);
        titleView.setTextColor(Color.RED);
    }
}

and add this at your Pref.xml file :

<ali.UI.Customize.MyPreferenceCategory android:title="@string/pref_server" />

Answer 2

Using Material Theme, you just have to override the following property :

<style name="YourTheme" parent="@style/Theme.MaterialComponents">
    <item name="colorAccent">@color/your_custom_color</item>
</style>

Answer 3

Actually just found out that preference category text using colorAccent.

If your app didn't using style of colorAccent, you can go to styles.xml and find
<item name="colorAccent">@color/colorPrimary</item>, and change the color as you want.

Answer 4

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.

Answer 5

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>
