问题描述

我正在 Android 上测试新的工具栏和 AppCompat 主题，但遇到了问题.我的工具栏标题文本在纵向模式下看起来大小正常，但在横向模式下变得相当小，尽管我没有在代码中做任何事情来更改标题的文本大小.以下是屏幕截图:

I'm testing the new Toolbar and AppCompat theme on Android and ran into a problem. My toolbar title text looks normal-sized on portrait mode but it became rather small on landscape mode although I didn't do anything in the code to change the title's text size. Here are the screen shots:

activity_main.xml:

<!-- A DrawerLayout is intended to be used as the top-level content view using match_parent for both width and height to consume the full space available. -->
<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    tools:context="com.techfunmyanmar.jujaka.ui.MainActivity">

    <android.support.v7.widget.Toolbar
        android:id="@+id/main_toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="?attr/colorPrimary"
        app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

    <android.support.v4.widget.DrawerLayout
        android:id="@+id/drawer_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <!-- As the main content view, the view below consumes the entire
             space available using match_parent in both dimensions. -->
        <FrameLayout
            android:id="@+id/container"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

        <!-- android:layout_gravity="start" tells DrawerLayout to treat
             this as a sliding drawer on the left side for left-to-right
             languages and on the right side for right-to-left languages.
             If you're not building against API 17 or higher, use
             android:layout_gravity="left" instead. -->
        <!-- The drawer is given a fixed width in dp and extends the full height of
             the container. -->
        <fragment
            android:id="@+id/navigation_drawer"
            android:name="com.techfunmyanmar.jujaka.ui.NavigationDrawerFragment"
            android:layout_width="@dimen/navigation_drawer_width"
            android:layout_height="match_parent"
            android:layout_gravity="start"
            tools:layout="@layout/fragment_navigation_drawer" />
    </android.support.v4.widget.DrawerLayout>
</LinearLayout>

styles.xml:

<resources>
    <!-- Base application theme. -->
    <style name="AppBaseTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <item name="windowActionBar">false</item>

        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/primary</item>
        <item name="colorPrimaryDark">@color/primary_dark</item>
        <item name="colorAccent">@color/accent</item>

    </style>

    <!-- Main application theme. -->
    <style name="AppTheme" parent="AppBaseTheme">

    </style>

    <style name="DrawerArrowStyle" parent="Widget.AppCompat.DrawerArrowToggle">
        <item name="spinBars">true</item>
    </style>
</resources>

推荐答案

我尝试设置工具栏的 android:titleTextAppearance 但没有应用该样式.然后我意识到我正在使用 AppCompat 主题，所以我使用了 app:titleTextAppearance 并且现在正在应用样式.看起来横向中的小写字母是内置 AppCompat.Toolbar.Title 样式本身的问题，所以我覆盖它以手动设置字体大小.最终代码:

I tried to set android:titleTextAppearance of the toolbar but the style wasn't being applied. Then I realized I'm using the AppCompat theme so I used app:titleTextAppearance and the style is now being applied. It looks like the small letters in landscape are a problem in the built-in AppCompat.Toolbar.Title style itself so I overrode it to set the font size manually. The final code:

工具栏 XML:

<android.support.v7.widget.Toolbar
        android:id="@+id/main_toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:titleTextAppearance="@style/ToolbarTitle"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

工具栏样式:

<style name="ToolbarTitle" parent="@style/TextAppearance.Widget.AppCompat.Toolbar.Title">
        <item name="android:textSize">20sp</item>
</style>
