没有填充的自定义标题栏(Android) [英] Custom title bar without padding (Android)

问题描述

所以我使用

有没有办法去除灰色边框?框架布局在 com.android.internal.R.id.title_container 中定义，因此通过 ID 访问框架会很脆弱.

解决方案

我一直在为同样的问题苦苦挣扎，现在我有了答案！

您可能已经在几个地方看到过，您需要创建一个 themes.xml 资源:

请注意，在讨论自定义标题栏的网站中并不经常提到您需要在视图、活动或应用程序级别选择此主题.我在应用程序级别通过向应用程序添加 android:theme 属性来做到这一点:

您还需要一个styles.xml 来定义WindowTitleBackgroundStyle.与我在网上看到的该文件的各种版本不同，我在文件中添加了一行，将填充设置为 0，从而消除了您抱怨的填充:

So I am using the techniques in this thread to use a custom background for my titlebar. Unfortunately the framework places my layout inside a FrameLayout (title_container) which has padding as seen below.

Is there anyway to remove the grey borders? The frame layout is defined in com.android.internal.R.id.title_container, so accessing the frame by ID would be fragile.

解决方案

I was struggling with this same issue and now I have the answer!

As you probably have seen several places, you need to create a themes.xml resource:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="MyTheme" parent="android:Theme">
            <item name="android:windowTitleSize">44dip</item>
            <item name="android:windowTitleBackgroundStyle">@style/WindowTitleBackground</item>
    </style>
</resources>

Note it is not often mentioned in the sites talking about custom title bars you need to select this theme at the view, activity, or application level. I do it at the application level by adding android:theme property to the application:

  <application android:icon="@drawable/icon"
               android:label="@string/app_name"
               android:theme="@style/MyTheme">

You also need a styles.xml to define that WindowTitleBackgroundStyle. Unlike the various versions of this file I have seen floating aroung the web, I have added one additional line to the file that sets the padding to 0 which gets rid of the padding you are complaining about:

<?xml version="1.0" encoding="UTF-8"?>
<resources>
    <style name="WindowTitleBackground">
        <item name="android:background">@android:color/transparent</item>
        <item name="android:padding">0px</item>
    </style>
</resources>
