Question

implementation "com.android.support:appcompat-v7:28.0.0-rc01"
implementation "com.android.support:preference-v14:28.0.0-rc01"

这是我build.gradle中的代码。我编写了settings_pref.xml。它在Android Studio和我的手机中无法正确显示。

这是settings_pref.xml。

<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <PreferenceCategory
        android:title="@string/settings_about">

        <Preference
            android:title="@string/settings_version"
            app:key="version"
            android:summary="%s"/>

        <Preference
            android:title="@string/settings_rate"
            app:key="rate"
            android:summary="@string/settings_rate_desc"/>

        <Preference
            android:title="@string/settings_licenses"
            app:key="licenses"/>

    </PreferenceCategory>

    <PreferenceCategory
        android:title="@string/settings_thanks">
        <Preference
            android:title="@string/settings_lizhaotailang"
            app:key="lizhaotailang"
            android:summary="@string/settings_lizhaotailang_desc"/>
        <Preference
            android:title="@string/settings_hongyang"
            app:key="hongyang"
            android:summary="@string/settings_hongyang_desc"/>
    </PreferenceCategory>

    <PreferenceCategory
        android:title="@string/settings_support">
        <Preference
            android:title="@string/settings_source_code"
            app:key="source_code"
            android:summary="@string/settings_source_code_link"/>
        <Preference
            android:title="@string/settings_send_advices"
            app:key="send_advice"
            android:summary="@string/settings_send_advices_desc"/>
    </PreferenceCategory>

</PreferenceScreen>

这是strings.xml

    <string name="settings_about">About</string>

如果我更改了低于28.0.0的支持库版本，如下所示：

implementation "com.android.support:appcompat-v7:27.1.1"
implementation "com.android.support:preference-v14:27.1.1"

它正确显示。

我该怎么解决？如果我不想更改我的支持库版本：28.0.0-rc01？

为什么PreferenceScreen在sdk版本28中无法正确显示？怎么解决呢？
