Question

我有一个Settings.xml布局，其中包含按钮，textviews等。我正在努力将其更改为使用PreferenceScreens进行设置布局。我知道我不能像我们在LinearLayout或其他任何方式中使用的那样使用按钮。我的问题如下：

有没有办法可以使用我的settings.xml中的按钮，视图到我的Preference_settings.xml？
有没有办法在Settings.xml和Preference_Settings.xml之间建立连接？

这是我的settings.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginLeft="5dp"
    android:layout_marginRight="5dp"
    android:orientation="vertical"
    android:weightSum="10" >

    <RelativeLayout
        android:id="@+id/top_panel"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dp" >

        <Button
            android:id="@+id/select_flight_button"
            android:layout_width="@dimen/settings_button_width"
            android:layout_height="wrap_content"
            android:textColor="@drawable/custom_text_color_for_buttons"
            android:textSize="@dimen/button_text_size"
            android:textStyle="bold" />      
    </RelativeLayout>


    <LinearLayout
        android:visibility="gone"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_gravity="bottom|center_horizontal"
        android:layout_weight="2.25"
        android:layout_marginTop="5dp"
        android:layout_marginBottom="17dp"
        android:gravity="top|center_horizontal"
        android:orientation="horizontal" >

        <ImageButton
            android:id="@+id/app_version_tablet_id"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginRight="5dp"
            android:background="@color/transparent"
            android:gravity="center_horizontal"
            android:src="@drawable/tablet_info" />

        <TextView
            android:id="@+id/last_outbound_sync_timestamp"
            style="@style/settings_sync_text"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="top"
            android:layout_marginTop="10dp"
            android:layout_marginLeft="5dp"
            android:focusable="false"
            android:text="@string/last_sync_time_unknown" />

</LinearLayout>

这是我的preference_settings.xml

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">

    <PreferenceCategory
        android:title="Flight Selection" >

        <Preference
            android:title="Change Flight"
            android:selectable="true"
            android:key="@string/choose_flight"
            android:icon="@drawable/icon_select_flight" />
        <Preference
            android:title="Close Flight"
            android:selectable="true"
            android:key="@string/close_flight_successful"
            android:icon="@drawable/icon_select_flight" />

    </PreferenceCategory>

    <PreferenceCategory
        android:title="Terminal Panel" >

        <Preference
            android:title="Change Terminal"
            android:selectable="true"
            android:icon="@drawable/icon_terminal" />

    </PreferenceCategory>

    <PreferenceCategory
        android:title="Printer Panel" >

        <Preference
            android:title="Choose Printer"
            android:icon="@drawable/icon_printer" />

    </PreferenceCategory>
        <SwitchPreference
            android:title="Enable Sync" />

</PreferenceScreen>

如果您想从布局中选择单个视图以添加另一个布局，那么不，您不能这样做。但是，可以在另一个布局中添加整个布局。

在preference_settings.xml

中也是如此

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">

<!-- Your layout views from settings will start from top place the layout wherever you want-->
<include layout="@layout/settings" />

<PreferenceCategory
    android:title="Flight Selection" >

    <Preference
        android:title="Change Flight"
        android:selectable="true"
        android:key="@string/choose_flight"
        android:icon="@drawable/icon_select_flight" />
    <Preference
        android:title="Close Flight"
        android:selectable="true"
        android:key="@string/close_flight_successful"
        android:icon="@drawable/icon_select_flight" />

</PreferenceCategory>

<PreferenceCategory
    android:title="Terminal Panel" >

    <Preference
        android:title="Change Terminal"
        android:selectable="true"
        android:icon="@drawable/icon_terminal" />

</PreferenceCategory>

<PreferenceCategory
    android:title="Printer Panel" >

    <Preference
        android:title="Choose Printer"
        android:icon="@drawable/icon_printer" />

</PreferenceCategory>
    <SwitchPreference
        android:title="Enable Sync" />
