android - CS0117 "Resource"不包含 "Xml"的定义

Question

我创建了 settings.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.preference.PreferenceScreen
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/my_preferences_settings">
    <android.support.v7.preference.PreferenceCategory android:title="Category 1">
        <android.support.v7.preference.SwitchPreferenceCompat
            android:key="key1"
            android:title="Switch Preference"
            android:summary="Switch Summary"
            android:defaultValue="true" />
        <android.support.v7.preference.EditTextPreference
            android:key="key2"
            android:title="EditText Preference"
            android:summary="EditText Summary"
            android:dialogMessage="Dialog Message"
            android:defaultValue="Default value" />
        <android.support.v7.preference.CheckBoxPreference
            android:key="key3"
            android:title="CheckBox Preference"
            android:summary="CheckBox Summary"
            android:defaultValue="true"/>
    </android.support.v7.preference.PreferenceCategory>
</android.support.v7.preference.PreferenceScreen>

在styles.xml中添加了preferenceTheme

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

  <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="colorPrimary">@color/ColorActionBar</item>
    <item name="colorPrimaryDark">@color/ColorActionBar</item>
    <item name="colorAccent">@color/accent</item>
    <item name="preferenceTheme">@style/PreferenceThemeOverlay</item>
  </style>

  <style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
    <item name="android:listDivider">@color/background3</item>
    <item name="preferenceTheme">@style/PreferenceThemeOverlay</item>
  </style>
  <style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />
  <style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />
</resources>

设置 fragment

using Android.OS;
using Android.Views;
using Android.Util;
using Android.Preferences;
using Android.Support.V7.Preferences;

namespace Aprepara.Droid.Activities.Fragments
{
    public class SettingsFragment : PreferenceFragmentCompat
    {
        public override void OnCreatePreferences(Bundle savedInstanceState, string rootKey)
        {
            AddPreferencesFromResource(Resource.Xml.settings);
        }

        public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
        {
            Log.Info("Aprepara.Droid", "SettingsFragment");
            // Use this to return your custom view for this Fragment
            return inflater.Inflate(Resource.Layout.settings, container, false);
        }
    }
}

但它显示资源中不存在 XML 的错误。

我正在使用这个例子作为引用......

有人能帮帮我吗？为什么资源中不存在 XML？

Answer 1

but it is displaying the error that XML does not exist in Resource.

在您的Resource文件夹中创建一个xml文件夹，并将您的settings.xml放入这个xml文件夹中.

效果:
