The textColor attribute isn't working. Here's my XML:
<PreferenceCategory
android:title="Title"
android:textColor="#00FF00">
Any ideas?
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" />
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.
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"/>
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.
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"
/>
For more customization visit v7 Preferences res
Important: I am using PreferenceFragmentCompat from lib v7 Preference.
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>
Or you can also use this answer
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.
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.

<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">
