Android 首选项片段文本颜色

我想更改 android 首选项片段中的文本颜色。我目前正在使用自定义主题来更改复选框图像、背景、onClick 突出显示，除了文本颜色之外，一切都非常有效。我不想使用默认主题，我想拥有自己的主题，这样一切看起来都是我想要的，但只是更改文本颜色，有人可以帮忙吗？

样式.xml

<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:android="http://schemas.android.com/apk/res/android">
    <style name="selectedTextStyle">  
        <item name="android:textSize">18sp</item>
    </style>
    <style name="buttonTextStyle">  
        <item name="android:textSize">20sp</item>
    </style>
    <style name="PreferencesTheme" >
        <item name="android:windowBackground">@drawable/lists_background</item>
        <item name="android:listViewStyle">@style/listViewPrefs</item>
        <item name="android:checkboxStyle">@style/MyCheckbox</item>

    </style>
    <style name="MyTextAppearance" parent="@android:style/TextAppearance">
        <item name="android:textColor">@color/black</item>
      </style>
    <style name="listViewPrefs" parent="@android:Widget.ListView">
        <item name="android:listSelector">@layout/list_selector_master</item>
        <item name="android:textAppearance">@style/MyTextAppearance</item>
    </style>
    <style name="MyCheckbox" parent="android:Widget.CompoundButton.CheckBox">
        <item name="android:button">@drawable/btn_check</item>
    </style>

</resources>

显现：

        <activity
            android:name="com.package.SettingsActivity"
            android:theme="@style/PreferencesTheme"
            android:configChanges="keyboard|orientation" >
        </activity>

活动：

import android.app.Activity;
import android.os.Bundle;
import android.preference.PreferenceFragment;

public class SettingsActivity extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // Display the fragment as the main content.
        getFragmentManager().beginTransaction()
                .replace(android.R.id.content, new SettingsFragment())
                .commit();

    }
    public static class SettingsFragment extends PreferenceFragment {
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);

            // Load the preferences from an XML resource
            addPreferencesFromResource(R.xml.preferences);

        }
    }

}

这是两个TextView对象来自偏好.xml http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/4.1.1_r1/frameworks/base/core/res/res/layout/preference.xml（布局为Preference):

    <TextView android:id="@+android:id/title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:singleLine="true"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:ellipsize="marquee"
        android:fadingEdge="horizontal" />

    <TextView android:id="@+android:id/summary"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@android:id/title"
        android:layout_alignLeft="@android:id/title"
        android:textAppearance="?android:attr/textAppearanceSmall"
        android:textColor="?android:attr/textColorSecondary"
        android:maxLines="4" />

所以看起来你可以覆盖textAppearanceLarge and textColorSecondary在你的主题中实现颜色变化。这是一个例子：

<style name="AppTheme">
    <item name="android:textAppearanceLarge">@style/MyTextAppearance</item>
    <item name="android:checkboxStyle">@style/MyCheckBox</item>
</style>

<style name="MyCheckBox" parent="@android:style/Widget.CompoundButton.CheckBox">
    <item name="android:button">@android:drawable/btn_star</item>
</style>

<style name="MyTextAppearance" parent="@android:style/TextAppearance.Large">
    <item name="android:textColor">#ff0000</item>
</style>
