Change text color of preference category in Android

  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" />

2. With XML

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"/>
