use this customize PreferenceCategory class :
使用此自定义 PreferenceCategory 类：
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 :
并将其添加到您的 Pref.xml 文件中：
<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) :
一种解决方案是为您的 PreferenceScreen 制作一个主题。所以在你的themes.xml 或styles.xml（最好把它放在themes.xml 中）：
<style name="PreferenceScreen" parent="YourApplicationThemeOrNone">
<item name="android:textColor">@color/yourCategoryTitleColor</item>
</style>
then in your AndroidManifest.xml :
然后在你的 AndroidManifest.xml 中：
<activity
android:name="MyPreferenceActivity"
...
android:theme="@style/PreferenceScreen" >
</activity>
It worked perfectly for me.
它非常适合我。

An easy way to do this is to set the custom layout for the preferenceCategory here:
一种简单的方法是在此处为首选项类别设置自定义布局：
<PreferenceCategory
android:layout="@layout/preferences_category"
android:title="Privacy" >
Then set your code inside your preferences_category layout file:
然后在您的首选项_类别布局文件中设置您的代码：
<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 PreferenceActivityin your Android Manifest and make sure that colorAccentitem exists. This color is taken by your PreferenceCategory.
要更改首选项类别的文本颜色，只需PreferenceActivity在您的 Android 清单中为您设置一个主题，并确保存在colorAccent项目。此颜色由您的PreferenceCategory.

Other way around will be mention the theme in your AppTheme, application level
其他方式将在您的AppTheme 中提及主题，应用程序级别
<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: 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
如需更多定制，请访问v7 Preferences res
Important: I am using PreferenceFragmentCompatfrom lib v7 Preference.
重要提示：我使用PreferenceFragmentCompat从LIB V7偏好。

Actually just found out that preference category text using colorAccent.
If your app didn't using style of colorAccent, you can go to styles.xmland find <item name="colorAccent">@color/colorPrimary</item>, and change the color as you want.
实际上刚刚发现使用colorAccent.
如果您的应用程序没有使用 样式colorAccent，您可以去styles.xml查找<item name="colorAccent">@color/colorPrimary</item>，并根据需要更改颜色。

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:
在您的 prefs.xml 中：
<com.your.packagename.MyPreferenceCategory android:title="General">
.
.
.
</com.your.packagename.MyPreferenceCategory>

Define your own PreferenceTheme and override colors.
定义您自己的 PreferenceTheme 并覆盖颜色。
<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>

Inspired by @AliSh answer, but I needed to only change the colour of onePreferencetext item. So, for all the Kotlin guys out there:
受到@AliSh 答案的启发，但我只需要更改一个Preference文本项的颜色。所以，对于所有的 Kotlin 人来说：
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:
然后把它放在你的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>

Using Material Theme, you just have to override the following property :
使用 Material Theme，您只需覆盖以下属性：
<style name="YourTheme" parent="@style/Theme.MaterialComponents">
<item name="colorAccent">@color/your_custom_color</item>
</style>
