以下是偏好设置屏幕的截图:

我还包括布局和java代码:

布局/ toolbar.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/primary_dark"
android:elevation="0dp"
app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
tools:ignore="UnusedAttribute" />

布局/ activity_settings.xml

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

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <include layout="@layout/toolbar" />
</LinearLayout>

XML / fragment_settings.xml

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
    <PreferenceCategory android:title="Notifications">
        <SwitchPreference
            android:defaultValue="false"
            android:key="currencyNotificationOnOff"
            android:title="@string/notification_enable" />

        <com.adwitiya.currencyplus.view.TimePickerDialog
            android:defaultValue="08:00"
            android:dependency="currencyNotificationOnOff"
            android:key="scheduleNotificationTime"
            android:showDefault="true"
            android:title="Notification Time" />
    </PreferenceCategory>
    <PreferenceCategory android:title="">
        <Preference
            android:key="about"
            android:title="@string/about" />
        <Preference
            android:key="disclaimer"
            android:title="@string/disclaimer" />
        <Preference
            android:key="help"
            android:title="@string/help" />
    </PreferenceCategory>
    <PreferenceCategory android:title="General">
        <Preference
            android:key="spreadWord"
            android:title="@string/prefs_spread_word" />
        <Preference
            android:key="rateUs"
            android:title="@string/rate_us" />
        <Preference
            android:key="feedback"
            android:title="@string/feedback" />
    </PreferenceCategory>
</PreferenceScreen>

SettingsActivity.java

public class SettingsActivity extends ActionBarActivity {

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

        setContentView(R.layout.activity_settings);

        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        getSupportActionBar().setHomeButtonEnabled(true);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);

        getFragmentManager().beginTransaction()
                .replace(android.R.id.content, new SettingsFragment()).commit();
        TimePickerDialog timePicker = new TimePickerDialog(this);
        PreferenceManager.setDefaultValues(this, R.xml.fragment_settings, false);
    }
}

SettingsFragment.java

public class SettingsFragment extends PreferenceFragment {

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

        handleSettingsOptions();
    }
    ....
}

我无法将工具栏保留在顶部,并且不能将首选项屏幕元素保留在其下方。滚动选项后,它会在工具栏顶部移动。

我正在使用单个首选项屏幕,每个首选项都会打开一个webview。

提前感谢您的回复。

修正了问题。我所做的更改如下:

  1. 从'activity_settings.xml'
  2. 中删除了工具栏
  3. 从“SettingsActivity.java”
  4. 中删除了与工具栏相关的代码
  5. 在'AndroidManifest.xml'中,我在活动中添加了'Theme.AppCompat.Light.DarkActionBar'主题(根据您的要求进行更改)。

希望这项工作对其他人来说,接受的答案对你不起作用。

布局/ activity_setting.xml 中更改代码,如下所示

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

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

<include layout="@layout/toolbar" />

<!-- added code -->
<FrameLayout
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"/>

</LinearLayout>

SettingsActivity.java 中,替换此代码

getFragmentManager().beginTransaction()
            .replace(android.R.id.content, new SettingsFragment()).commit();

有了这个

getFragmentManager().beginTransaction()
            .replace(R.id.container, new SettingsFragment()).commit();

以下对我有用:

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/coordinatorLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <include layout="@layout/toolbar" />

    </android.support.design.widget.AppBarLayout>

    <android.support.v4.widget.NestedScrollView
        android:id="@+id/contentPanel"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fillViewport="true"
        app:layout_behavior="@string/appbar_scrolling_view_behavior" />

</android.support.design.widget.CoordinatorLayout>

这样您仍然可以使用常规工具栏,其主题将保持不变。
