Question

我有一个偏好片段：

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

public class SettingsFragment extends PreferenceFragment{

@Override
public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    addPreferencesFromResource(R.xml.preferences);
}

}

加载此xml资源文件：

<?xml version="1.0" encoding="utf-8"?>

<PreferenceCategory
    android:title="Checkbox Preference">

    <CheckBoxPreference
        android:key="update"
        android:defaultValue="True"
        android:summary="joo"
        android:textColor="@color/colorText"
        android:textSize="40dp"
        android:title="@string/prefUpdate"/>

    <CheckBoxPreference
        android:key="inspection"
        android:defaultValue="False"
        android:summary="joo"
        android:textColor="@color/colorText"
        android:textSize="40dp"
        android:title="@string/prefInspection"/>

</PreferenceCategory>

我在此活动中显示它：

import android.app.Activity;
import android.app.FragmentManager;
import android.app.FragmentTransaction;
import android.os.Bundle;

public class SettingsActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    FragmentManager settingsFM = getFragmentManager();
    FragmentTransaction settingsFT = settingsFM.beginTransaction();
    settingsFT.replace(android.R.id.content, new SettingsFragment());
    settingsFT.commit();

}

}

此活动的主题是：

<style name="AppTheme" parent="Theme.AppCompat.NoActionBar">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
  <item name="android:windowBackground">@color/colorWindowBackground</item>        
    <item name="android:windowActionBar">false</item>
</style>

问题是，没有显示android：summary和android：title，只有复选框可见。文本颜色设置为黑色，背景颜色设置为白色。

编辑：不知何故，文字颜色设置为黑色，但标题和摘要为白色

我的颜色：

<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="colorPrimary">#3F51B5</color>
<color name="colorPrimaryDark">#303F9F</color>
<color name="colorAccent">#FFFFFF</color>
<color name="colorWindowBackground">#FFFFFF</color>
<color name="colorText">#000000</color>
<color name="colorButtonPressed">#2a3993</color>
<color name="colorGrayDivision">#484848</color>
</resources>
